PREFACE.

THE present part of the “Illustrations of Typical Specimens of Lepidoptera Fleterocera in the British Museum” deals exclusively with the Tortricide of North America in the National Collection. Many species originally named by the late Mr. Walker are now fully described and figured. But our knowledge of this group has received, besides, an important addition by numerous new species discovered and collected by Lord Walsingham in 1871 and 1872, chiefly in California and Oregon. These are now for the first time described, the types

having been presented by him to the Museum.

INTRODUCTION.

In describing several new species of TYortricide from North America, and re- describing such of Mr. Walker’s species as had not been anticipated by other authors, and of which the types are now in the British Museum, I have thought it advisable to adopt as far as possible the system of classification laid down by Heinemann in his ‘Schmetterlinge Deutschlands und der Schweiz,’ published in 1865.

Many systems of generic subdivision have been suggested for this difficult group; but all appear to have been founded upon a study of European species only. So far as I have been able to judge, none of these various systems are sufficiently perfect and natural to facilitate the arrangement of a cosmopolitan collection. It is very desirable that some comprehensive system should be devised; but for this purpose a very careful study of specimens from all parts of the world is obviously necessary, and it may be long before such a work can be successfully undertaken. Until this has been done, any arrangement of this group of insects must, I think, be considered, in part at least, provisional.

In the meanwhile Heinemann’s system, although not infallible when applied to large numbers of species with which he was necessarily unacquainted, seems to afford a wider and sounder basis for generic classification than those of other authors. He attaches much value to differences of neuration; and although

Vl INTRODUCTION.

perhaps (in opposition to the views urged by the late Mons. Peyerimhoff in the ‘Annales de la Société Entomologique de France,’ 1876, p. 577) he depends too much upon the presence or absence of the costal fold for generic division, his critics have not yet produced any system of classification which can be said to supersede that of Heinemann, or to depart from the general guiding principles which he laid down. Many genera which have been perhaps linked together by the discovery of intermediate forms, or which have not presented in themselves sufficiently strong permanent characteristic differences, besides some few, perhaps, which might possibly have remained clearly defined and acknowledged, seem to have been merged by him under more comprehensive generic titles, in which they have sunk to the rank of subgenera. It may be objected to this system that distinctions sufficient to separate the numerous subgenera are really equally

sufficient to be of full generic value.

Whilst following the method of determination laid down by Heinemann, I have ventured so far to depart from his system of arrangement for the purposes of this volume as to recognize his subgenera as genera, thus avoiding that departure from strict binominal nomenclature which is involved in the practice of writing names in such a form as Tortrix (Cacecia) rosaceana, Harris;” and had I been following it less faithfully I should have been much disposed to break up the large genus Pedisca into at least three separate divisions, which could, I think, be clearly defined.

Heinemann uses Grapholitha, H.-S., as one of the subgenera of Grapholitha, Tr. Since Heinemann’s limitation of the subgenus is not exactly coextensive with Herrich-Schaffer’s limitation of the genus, I have preferred to speak of Grapho- litha (1.-S.), Hein., as expressing that Heinemann’s subgenus is adopted as distin-

guished from the larger and more comprehensive genus of Treitsche.

An additional reason for adopting Heinemann’s method seems to be presented by the fact that Prof. C. H. Fernald, of Maine State College (who is, I believe, about to publish a complete list of the North-American Tortricide), has been guided in his investigations by the rules laid down by Heinemann; and as the present volume treats exclusively of North-American species, it will be found convenient that their classification corresponds, as far as possible, with that which

has been adopted in compiling such a national catalogue.

INTRODUCTION. Vil

I must express my grateful acknowledgments to those gentlemen who have assisted me in acquiring the necessary information for this volume—to H. T. Stainton, Esq., to Mr. C. G. Barrett, and others in this country, to Prof. P. C. Zeller, of Stettin, and especially to Prof. Fernald, of Maine State College, and to Mr. Cresson and others of the Entomological Society of Philadelphia, for enabling me to become acquainted with many of the species described by American, as well

as European, authors whose types I have had no opportunity of examining.

I hope that all adequate precaution has been taken against mere additions to synonymy, which in this group of insects is already so extensive ; but I can scarcely expect to have entirely avoided the error of redescription ina family of Lepidoptera peculiarly difficult to render recognizable even by coloured figures, and equally difficult to recognize from mere descriptions. Many Californian species approach very closely to well-known European forms, but seem to have some constant, although slight, distinguishing peculiarities. I have not knowingly ventured to describe any such as new, except where I have been able carefully to compare a considerable series of specimens, as in the case of Penthina vetulana, Penthina consanguinana, Pedisca hirsutana, Pedisca illotana, Rhyacionia juncticiliana, and others. I have in all cases stated the number of specimens now in the British Museum collection only, without reference to those available for comparison in my own collection.

To facilitate the study of the North-American Tortricide represented in the collection of the British Museum, I have given after each genus a list of such of Mr. Walker’s species as were placed in that genus by him, but which, for various

reasons, have not now retained this position in the catalogue of types.

In these lists reference is made to such synonyms only as are entitled to take precedence of the names given by Mr. Walker. For these Iam indebted partly to Messrs. Grote and Robinson (Trans. Amer. Ent. Soc. 1868, ii. pp. 83, 84), partly to information received from Prof. Fernald, whose observations on Walker’s types will probably appear before this volume is printed, and partly to my own observation and comparison of Walker’s specimens, by which means I have in all cases carefully verified the synonymy.

I have ventured to add a list of all the European species which up to

the present time have been observed in North America, together with such as I

Vili INTRODUCTION.

have myself met with or recognized, and which have not before been recorded as occurring in that country.

Mr. Edwin Wilson has exercised great care and patience in faithfully render- ing the form and markings of the various specimens. In the case of some of Mr. Walker's types, which are in extremely poor condition, this has been a difficult task; but the measure of success with which it has been accomplished will,

I trust, be the means of preserving a reliable record of this portion of Mr. Walker’s work.

found in Walker’s type of sudnivana, especially the brown (not black) colouring of the costal patch, and the grey (not pure white) cilia of the fore wings, as well as its smaller size. I took a specimen at Washington in May 1871; and I have seen another specimen from North America, both of which approach the Muropean form more closely in these particu- lars. It may eventually be found that the true doscana also occurs there.

Teras nivisellana. (Plate LXI. fig. 3.)

Head, palpi, and antenne dark ferruginous brown; thorax white. Fore wings white, with numerous tufts of raised scales ; a triangular brownish patch rather beyond the middle of the costa, containing towards its apical angle a bluish-purple shade, internally margined with black ; an ochreous shade runs through the costal patch and is diffused over the wing towards the anal angle, containing one or more spots of raised scales of the same colour and extending towards some rich ferruginous-brown streaks near the apical margin and apex; there is a conspicuous tuft of raised ferruginous-brown scales near the basal third of the dorsal margin, with a small black dot on the fold immediately above it: underside pale reddish brown, the costa touched with white: cilia reddish brown. Hind wings pale reddish fuscous. 2 92. Expanse of wings 16 millims.

Mount Shasta, California, August 1871, at an elevation of about 5000 feet. The species was also met with in May of the following year near Rouge River, in Oregon.

This is evidently the North-American representative of the common European T. varie- gana, Schiff.; but it differs from all varieties I have seen of that insect in the costal trian- gular spot being distinctly divided from the apical shade, as well as in the form of the apical shade itself, which in the species above described occupies a wider space on the dorsal than on the costal margin. I should hesitate to consider it a mere variety unless some intermediate forms should yet be found.

Teras simpliciana. (Plate LXI. fig. 4.)

Antenne fuscous; head, palpi, and thorax white. Fore wings white with a slight yellowish tinge, with some streaks of dusky scales towards the apex: a purplish-black sub- obtuse triangular patch at the costa slightly beyond the middle, reaching over the upper edge of the cell; in this patch are a few slightly raised darker scales : a minute black spot lies in the basal third of the wing below the fold, and sometimes another smaller one on the cell above it, rather nearer the base. Hind wings tinged with brownish grey; cilia paler. 2 9. Expanse of wings 14 millims.

Teras foliana. (Plate LXI. figs. 5 & 6.)

Head and palpi ochreous, the latter projecting not more than the length of the head beyond it, second joint thickly clothed with ochreous scales which partly conceal the short apical joint; antennz brownish ochreous, slightly pubescent in the male; thorax brownish ochreous in front, pale straw-colour behind, where there is a raised tuft of scales of the same colour. Fore wings—with the costa arched ; apex produced, almost falcate; dorsal margin nearly straight—pale straw-colour, more or less suffused or reticulated with ochreous brown; a very pale yellowish triangle is preceded by a pale oblique chestnut-brown shade from the middle of the costa, which in some specimens is carried round more faintly on its outer edge ; a narrow pale chestnut-brown line runs along the apical margin ; and in some specimens (as in fig. 6) the whole surface of the wings is strongly reticulated with the same colour: cilia at the anal angle straw-coloured, along the apical margin paler: underside glossy pale reddish straw-colour, the costal triangle sometimes indicated in pale staw-colour. Hind wings pale straw-colour, with a faint rosy tinge; cilia and legs ighter. Hxpanse of wings 19-21 millims.

Southern extremity of Lower Lake, Lake County, California, June 23rd, 1871.

This species is nearly allied to Teras contaminana, No. 683 of Staudinger and Wocke’s Catalogue, placed by Wilkinson in the genus Dictyopteryx of Stephens, which genus is

apparently merged in Jeras, Tr., by Heinemann. The types figured are both males. There are six males and one female in the Museum

collection.

Teras pulverosana, Walk. Cat. Lep. Het. xxviii. p. 291. Sciaphila implexana, Walk. Cat. Lep. Het. xxvui. p. 338.

Palpi projecting about the length of the head beyond it, thickened in the middle; the apical joimt short, depressed. Fore wings—with the costa rather abruptly arched near the base, straighter beyond; the apical margin oblique, slightly impressed below the apex— purplish cinereous, slightly irrorated with fuscous ; paler beneath, with two oblique angulated lines of slightly raised fuscous scales, the first before the middle forming the inner edge of an indistinct purplish-fuscous fascia; the second beyond the middle reaching the apical margin above the anal angle and enclosing the apical portion of the wing, which is indistinctly streaked and mottled with purplish fuscous. Hind wings paler, with a faint purplish tinge, indistinctly speckled transversely towards the costal margin. Type ¢. Expanse of wings 19 millims.

St. Martin’s Valls, Albany River. Presented by Dr. Barnston.

I have thought it desirable to figure this specimen, which, although nearly allied to the common Teras hastiana, Linn., and not in good condition, is probably the type of a smaller and distinet species, having perhaps also a wide range of variation. It is apparently darker than any of the specimens figured by Robinson in plate vii. of the ‘Transactions of the

B2

Caput vestitum. Palpi capite bis longiores utrinque a medio fastigati. Antenne 3 utrinque pectinate. Ale antice latitudine plus quam bis longiores ; costé precipue apud basin arcuatd, apice vix producto: 3 venis undecim singulis, vend septimd apud costam ante

apicem finitd; 3 vend septima furcatd, apice furcam interjacente.

Head thickly clothed above and in front. Palpi twice as long as the head, thickened in the middle, the apical joint slightly depressed, tapering. Antenne pectinated on both sides in the male. Fore wings more than twice as long as wide, without a costal fold; costa arched abruptly at the base; apex scarcely produced ; apical margin not oblique, slightly concave below the apex : veins of the fore wings in the male eleven, branch 7 ending in the costal margin. The female slightly larger than the male and almost without ornamentation ; branch 7 of the fore wings forked before the apex, which lies between its two branches.

This genus is separated from Lofotenia, H.-S., Heterognomon, Ld., &c. by the pectinated antenne and by the number of veins in the fore wings of the male; differing in this latter character, as well as in the form of the wings themselves, from Amphisa, Curt., Dichelia, Gn., &c., in which genera veins 7 and 8 arise from a common pedicle in both sexes.

of the hind wings. Fore wings pale straw-colour ; the costa arched somewhat abruptly at the base, where there is a strong chestnut-brown shade: a wedge-shaped spot of a similar colour points outwards from the costa before the middle towards the anal angle ; a narrow chestnut- brown shade extends vertically downwards from the apex halfway along the apical margin, the wing thence being rounded off obliquely to the dorsal margin: cilia very pale straw- colour. Hind wings yellowish white, with a chestnut-brown shade at the apex. Legs pale straw-colour; the first pair of tarsi chestnut-brown above. The female slightly larger than the male; fore wings unicolorous ochreous chestnut, hind wings yellowish white: antenn simple. 3 ¢,12. Expanse of wings ¢ 30 millims., ? 33 millims.

Var. adumbranum.

In this var. ¢ the chestnut-coloured wedge-shaped mark on the costa is much occupied by dark fuscous scales, and it blends into a chestnut shade, which is continued along the costa to the apex, and downward through the wing to the dorsal margin beyond the middle, forming a sort of large irregular triangle, from the inner edge of which a slight projection extends towards the base of the wing along the fold. There is an oblique line of faint fuscous scales halfway between the costal wedge-shaped mark and the apex, reaching downwards towards the anal angle. The space between the thorax and the middle shade is of a more ochreous tint than the space beyond it above the anal angle, which is very pale straw-colour. The female has the fore wings darker than in the typical form, but nearly unicolorous; a paler oblique fascia, scarcely perceptible beyond the middle; the space above the anal angle also pale. 1 ¢,1 9. Expanse of wings ¢ 30 millims., ? 33 millims.

Both varieties of this species occur in the month of August, on the western slopes of Mount Shasta, California, at an elevation of about 6000 feet, among thickets of Man- zanita,”’ Arctostaphylos glauca (Lindl.), on which I have little doubt the larva feeds. Ina

considerable series I have met with no varieties intermediate between the two forms above described ; but it would be at least premature to consider them distinct species.

Palpi very long, projecting fully three times the length of the head beyond it; the second joint nearly three times as long as the apical joint, slightly enlarged towards its base, tapering forward: antennz simple. Fore wings—with the costa abruptly arched near the base, straight beyond, the apex not rounded; apical margin straight, not oblique—tawny fawn-colour, the whole surface streaked with very minute detached streaks of tawny-fuscous scales in broken

wavy lines, some slightly raised; with a slender raised tawny-fuscous line from about the middle of the costa, bulged outward, and running to the dorsal margin before the anal angle ; another from the costa before the apex to the anal angle, nearly parallel to the apical margin, and a very slender similar line along the apical margin itself. Hind wings with a rufous tinge, very faintly mottled; cilia paler. Underside of fore wings reddish ochreous. Type 9. Expanse of wings 20 millims.

With a specimen from San Domingo and another from Ega are two specimens labelled “United States, Doubleday.” A marginal note in the British Museum register, by Mr. E. Doubleday, states that the collection presented by him was made by himself in the United States in 1837-1838, with a few additions from other sources,”—I presume, North-American sources. In any case there seems to be no sufficient reason for doubting that two specimens of the species above described are from North America.

The species is most nearly allied to Tortri#’”’ laterana, Rob. ; but whereas in Robinson’s species the “‘central fascia is distinctly limited’ and “filled in with blackish above and deep ferruginous below the middle,’ Walker’s rostrana has the raised margins of the central fascia interrupted, and the interjacent space scarcely perceptibly darker than the ground- colour of the wing; moreover the general arrangement of the lines is not the same in both species, so far as I am able to judge from specimens in my own collection. Walker’s descrip- tions of his three species—rostrana, restitutana, and connexana—will be found to be, almost word for word, the same, the only noticeable difference being in the palpi.

rostrana. “Third joint nearly half the length of the second.” restitutana. “Third joint not more than one third the length of the second.” connexana. “Third joint not more than one fourth the length of the second.”

I have been unable to perceive these differences in his type specimens, which appear to belong without doubt to one and the same species.

CACHCIA, Hib.

Cacecia patulana. (Plate LXI. fig. 1.) Tortrix patulana, Walk. Cat. Lep. Het. xxviii. p. 325.

Palpi short, thickened in the middle, projecting nearly the length of the head beyend it; together with the head brownish ochreous: antenne with the basal joint thickened, paler. Fore wings—with the costa rounded towards the base, deeply impressed beyond the middle ; the apex produced, subfalcate ; the apical margin concave below the apex—shining pale reddish straw-colour, thickly covered with minute detached transverse streaks of slightly raised black and chestnut-brown scales: three subobsolete, abbreviated, oblique chestnut-brown fasciz are faintly indicated—the first very indistinct near the base; the second from the middle of the costa ; and the third beyond it, followed by four minute very oblique black streaklets in the depressed portion of the costa: cilia at the apex chestnut-brown, below it paler. Hind wings very pale straw-colour, tinged with reddish towards the apical margin. Underside of

This species, which seems to be a true Cacecia, should properly have been figured on Plate LXII., among the other species of that genus.

Fore wings—fully twice as long as wide, with the costa arched at the base, concave beyond the middle, with a well-developed appressed costal fold in the male ; apex produced ; apical margin scarcely indented below the apex—reddish chestnut, with shining whitish ochreous spots and markings contaiming some silvery scales: an irregular whitish ochreous oblique fascia, angulated at its outer edge below the middle, forms the external margin of a rather mottled basal patch ; beyond it, about the middle of the costa, is a triangular whitish ochreous spot, followed by two irregular spots of the same colour tending towards the anal angle, giving the appearance of an oblique fascia broken up into three parts, the middle part preceded by a spot of fuscous scales at the end of the cell: beyond the median costal spot are four smaller spots, also on the costa, the third from the apex being the most conspicuous : cilia pale whitish ochreous. ‘Thorax and abdomen whitish ochreous. Hind wings pale reddish chestnut. The anal appendages large and hirsute. ‘Type g. Expanse of wings 20 millims.

The locality of Walker’s type is not known; but it agrees precisely with Robinson’s figure, who gives Texas as. the habitat of the species. I have several specimens from Texas in my own cabinet (some now added to the national collection), which, although exhibiting some variation from the original type, are probably correctly referred to this species.

The very decided costal fold in the male seems to separate this species from the genus Lozotenia according to Heinemann’s limitation, to which reference is made in the remarks which follow the description of Cacecia argyrospila.

I have thought it desirable to figure a variety of this species received from Canada, which approaches somewhat nearly to the Texan varieties mentioned above, but is perhaps even more deprived of the typical markings.

In this specimen, a male, the palpi (which are missing in the type) are slender, not profusely clothed, having the apical joint exposed; the antennz strongly pubescent. The fore wings pale yellowish fawn-colour, shaded with brown towards the costa and with scattered fuscous scales towards the apical margin; four very pale yellowish-fawn spots on the costa, the first rather triangular scarcely beyond the middle, the last two towards the apex containing some silvery scales posteriorly ; a spot of fuscous scales at the end of the cell is followed by a pale shining dash. The fascizeform arrangement of the pale markings in the type is completely lost in this variety. The dorsal margin is touched

Cacoecia transiturana, Walk. Cat. Lep. Het, xxyiil. p. 312. Tortrix sanbornana, Rob. Trans. Am. Ent. Soc. u. pl. i. fig. 8.

Palpi short, reddish ochreous, the apical joint obtuse. Head, antennz, and fore wings reddish ochreous; the latter with minute transverse irregular reddish-brown streaks, the most conspicuous of these forming the inner margin of an oblique subobsolete central fascia, which contains some purplish-fuscous scales towards the costa and below the middle, and reaches the dorsal margin before the anal angle. Beyond the middle of the costa is a spot also containing a shade of purplish fuscous, and indicating a subobsolete abbreviated fascia pointing towards the apical margin above the anal angle; there is also a subobsolete outwardly oblique basal patch, indented above the middle. Hind wings pale greyish ochreous, darker towards the abdominal margin: cilia concolorous, but very shming. Type 9. Ex- panse of the wings 26 millims.

Robinson gives Texas, Florida, Massachusetts, Pennsylvania, and New York as localities for the species.

Head and palpi brownish ochreous ; thorax and antennze deep brownish red. Fore wings —with the costa arched to the middle, flattened towards the apex; an appressed costal fold at the base in the male; the apical margin not indented, slightly oblique—deep brownish red, with several paler transverse streaks and mottlings, especially noticeable above the anal angle and before the middle of the dorsal margin; with three conspicuous shining yellowish- white costal spots—the first halfway between the middle and the base of the wing, elongate oblique, abruptly terminated on the upper edge of the cell ; the second triangular (not oblique or fascizeform, as in some varieties of the same species from California), interrupted on the costa by one or two minute reddish-brown costal dots ; the third near the apex, smaller than the preceding ones, blending into a pale streak before the apical margin. Hind wings brownish fuscous, with a reddish tinge towards the apex. Hxpanse of wings 20 millims.

In paler varieties, such as fig. 6, the reddish-brown colour is restricted to an oblique median fascia, a costal spot, and an indistinctly mottled basal patch, all possible intermediate gradations being met with.

CACCICIA. 9

Type ? (fig. 5): Georgia, from Mr. Milne’s collection. Var. ¢ (fig. 6): May 19, 1871, near San Francisco.

I should have been inclined to follow Prof. Zeller in placing this species in the genus Lozotenia, on account of the apex not being produced as in most species of Cacwcia ; but it cannot be said to have only a weak costal fold, “sehr schwachem Umschlage und zuriick- gestrichener Behaarung an demselben,” which is considered by Heinemann (p. 31) to be characteristic of LoZotenia, the fold in this species being very decided.

The species also occurred about Mendocino in the middle of June, and as far north as Mount Shasta in August. One specimen emerged on the 21st of June from a pupa found a few days previously between united leaves of A’sculus californica (Nutt.), the Californian horse-chestnut.

It is widely distributed—Missouri, Ohio, Massachusetts, New York, and Texas being given as localities for it by Zeller and Robinson.

There are now five males and one female in the collection, besides the two named above.

Retinia georgiana, Walk. Cat. Lep. Het. xxvii. p. 372. Tortrix georgiana, Grote, Bull. Buff. Soc. pl. i. fig. 4, vol. 1. p. 15.

Palpi projecting nearly the length of the head beyond it, together with the head reddish ochreous, the short apical joint exposed: antennz dull reddish ochreous, pubescent in the - male. Kore wings—with appressed costal fold at the base in the male; the costa rounded towards the base; apex rounded; apical margin convex—bright reddish chestnut, with shining pinkish ochreous bands and mottlings ; a wide basal patch, its external margin out- _wardly angulated at the middle, consists of three parallel shining pinkish ochreous fasciz widening in equal gradations from the base; a rather narrow oblique fascia of the same colour, from the middle of the costa running to the aval angle, is divided about the middle into three separate branches, all reaching the dorsal margin, the first only bemg narrowly interrupted below the middle (in some varieties these three branches become detached and form separate spots); one or more pinkish ochreous streaks cross the apical portion of the

_ wing from the costa to the apical margin: cilia pinkish ochreous. Hind wings brown, with

pale ochreous cilia. Type 2. LExpanse of wings 23 millims. Georgia. From Mr. Milne’s collection.

In the above description I have departed from the usual custom in taking the darker shade to be the ground-colour.
