Head and Thorax greyish fuscous, mixed with ochreous and pale cinereous scales. Forewings pale brownish ochreous, sprinkled with greyish fuscous scales on a short basal patch, produced along the dorsum, where the dark sprinkling becomes thicker and is dilated outward and upward nearly to the middle, forming, with a thinner sprinkling on the costa before the middle, an ill-defined broad band interrupted by a narrow pale cinereous space along the cell ; this is extended outward, gradually widened towards the apex, which it does not reach, and is interrupted by an irregular broad greyish fuscous band, obliquely placed, crossing the end of the cell, but not reaching to the costa or dorsum ; its upper and lower margins are produced respectively in narrow greyish fuscous lines which meet and enclose the outer end of the pale cinereous space which obviously represents the upper fold of the wing; above it are three or four * I retained the genus Lineodes, of which I possessed a fairly representative collection, owing to its having been originally included in the Pterophorina ; for this reason Mr Meyrick did not deal with Lineodes in treating of the Pyraustidae to which family it belongs.

The abdomen is whitish with transverse bands of tawny reddish brown across the segments, the ovi- positor is strongly extruded. This species so greatly resembles Thyrocopa gigas Btl., that great care must be taken in separating them. In the case of the t no real difficulty arises owing to the structure of the antennae, but in the $ it will be found better to rely upon the com- parative length of the terminal and median joints of the palpi ; the terminal being much shorter in proportion to the median than in Thyrocopa gigas, although there is much variation in their relative lengths in this species. 14.

On comparing Mr Meyrick's specimens, determined by him as usiiata Btl, on which he founded the genus Thyrocopa, I am compelled to regard them as representing a species distinct from Dr. Butler's type. It is possible that the error originated through the Rev. T. Blackburn having retained in his own collection specimens erroneously regarded as representing his No. 69, which he sent to the British Museum. The chief points of difference appear to be that the true tisitata Btl has darker, less powdery, and more uniformly coloured forewings, and very distinctly darker hindwings, the whole insect being more shiny with a slight purplish gloss which is not apparent in Meyrick's specimens. The % is larger than the ^, but the average size of specimens is certainly smaller than that of the true tisitata Btl, The above description is taken from a J in fair condition which was one of the original types of ^tisitata Meyr.

No confusion can arise between Azinis hilarella $ and any species of Ethnia, the large mat of scales on the underside of the hindwings, which are black above except in the flexal region, at once distinguish it. Azinis hilarella %, which is with difficulty distinguished from some of the species o{ Ethmia, by appearance only, may be at once recognised by the transverse vein connecting the discoidal vein to vein 8. The true genus Azinis Wkr. (^^ Theoxenia Wlsm.) has as yet only been recorded from Ceylon. No other species belonging to the Oecophoridae occurring in Hawaiia and colonella being confined to gardens in Honolulu, where it feeds on a cultivated plant, at present unrecorded, it is probable that the species has been introduced with the plant on which it feeds from one of the groups of islands. Mr Perkins noted it as " common at Honolulu — introduced." HI. HYPONOMEUTIDAE. = ELACHISTIDAE M^yV, + FLUTELLIDAE Meyr. 16. Batrachedra Stn. Type (i) G7^acillaria praeangusta Hw. (Stn. 1854).

This is a most difficult insect to describe ; its general appearance is a pale yellowish green, with indistinct mottled shading, and small ill-defined raised spots, it has however no very characteristic markings, although certainly distinct from all other species known to me. 74, (2) Aphthonetus fugitivay sp. nov. (PI. XV. fig. 25). Antennae stout, hoary greyish. Palpi pale hoary grey, dusted with fuscous. Head and Thorax hoary greyish. Forewings hoary greyish- white, spotted and dusted with olivaceous fuscous, some of the spots on the basal half having an admixture of ochreous scales with a tendency to be raised above the wing-surface ; it is difficult to say that any spots are more distinct than others, but if such could be selected they would be two costal spots, one before and one beyond the middle (above and between which the cilia, which extend along the whole margin, are very pale ochreous) and another about the end of the fold — the whole wing has thus a mottled appearance without defined pattern ; cilia hoary greyish, intermixed with brownish fuscous speckling. Exp. al. 14 mm. Hindwings and cilia shining, leaden greyish, Abdom.en shining, pale greyish cinereous, the usual three smooth basal patches being brownish fuscous.

Kauai : Mts., 3000-4000 ft, (5) v.-vi. 1894 ; Halemanu. 4000 ft, (17) v. 1895. Twenty-two specimens. This species varies much in the contrast between the darker and paler portions of the wmg. In some specimens the oblique cinereous fascia dividing the basal from the median portion is quite absent, while in others again the tendency of the shades, at least beyond where the fascia should be, is longitudinal ; in intermediate forms the central portion is obscurely outlined and tends to assume the form of a large costal triangle reaching downward to the fold. The head, thorax and cilia are concolorous with tlie wing, the latter usually partaking of the pale stippling which characterises its lighter portions. The forewings are somewhat narrower and more pointed than in the allied species corticicolor and mediocris. 76. (4) Aphthonetus corticicolor, sp. nov. (PI. XV. fig. 27). Antennae bronzy brownish. Palpi pale brownish cinereous, shaded with fuscous externally. Head and Thorax brownish fuscous. Forewings dull brownish ochreous, much suffused and mottled with tawny brown and fuscous, with tufts of raised scales ; an outwardly oblique tawny brown basal patch is followed by a pale oblique fascia, almost entirely obliterated by fuscous scaling, this is followed by a wider oblique tawny brown band before the middle, diffused outwardly on its lower half and confluent with the regular brown and fuscous mottling which extends to the apex ; cilia brownish cinereous, tawny fuscous on their basal half at the termen.

Forewings dark brown, shaded with fuscous about the basal half of the fold, 6j — 2 520 FAUNA HAWAIIENSIS the brown ground-colour being mapped out in one or more bowed-out wavy shades by the intervention of pale brownish ochreous costal patches (one before, one at, and one beyond the middle) more or less diffused across the wing ; this is especially noticeable in the third or outer patch, its semicircular extension preceding the dark brown apical region where some pale brownish cinereous mottling occurs, also around the margins and through the cilia ; on the dorsum beyond the middle a pale patch is even more conspicuous than those on the costa. Exp. al. 13 — 15 mm. Hindwings greyish ; cilia brownish grey. Abdomen and legs pale brownish cinereous. Type t (26758) Mus. Wlsm, Hab.

The distinction of this species from corticicolor, Wlsm., and others is sufficiently obvious when looking at them side by side, but the points of difference are exceedingly difficult to describe, among these the pale dorsal patch may be chiefly relied upon. 78, (6) Aphthonetus passerella, sp. nov.

Abdomen moderate. Legs, hind tibiae loosely haired. The species are generally variable, the ^ in some species with expansible lateral thoracic hair-pencil. Neelysia is probably derived from Hyposmocoma, through Dysphoria (or an ally), having veins 4 and 5 of the forewings stalked. The loss of a vein in Neelysia and Aphthonetus is thus indicated as caused by coincidence of these veins. Aphthonetus differs in emitting 6 of the forewings from 7, in having 6 and 7 of the hindwings stalked, in the clothing of the median joint of the palpi and the scale- tufts on the wing-surface. 104.

In one variety (281 12) the white is distinctly suffused with rust-brown along the dorsum, the basal patch being also strongly tinged with the same colour. This species differs from scolopax in the much more conspicuous white costal spot and in the clearer definition of the pattern, also in the form of the outer pale fascia, which in this species tends to encroach, above the middle, on the dark space preceding it. It differs from tetraonella in the possession of a subcostal hair-pencil. 297. (161) Hyposmocoma tetraonella, sp. nov. (PL XXIV. fig. 2).

Some specimens are paler than the type and lose the marginal spots. The descriptions of the varieties of this species show a wide range of difference in intensity and distribution of colour. I had originally regarded them as distinct, but the intergradations are numerous and it appears to me to be one of the rare instances in which a species ranging over several of the islands fails to establish for itself any recognisable local form. The size as well as the colour of the specimens is very variable and this difference is to be found in connection with each separate pattern or peculiarity. If anyone had before him the varieties described above without the intermediate gradations he would undoubtedly regard them as distinct species, but in the absence of a knowledge of their life-histories it seems preferable to describe them as varieties rather than species. 312.

Labial Palpi moderately long, recurved ; median joint considerably thickened above and beneath with dense, somewhat rough scales, attenuated towards base ; terminal joint as long as median, acute, posterior edge from base nearly to apex clothed with long, dense, obliquely projecting scales. Ocelli absent. Haustellum strong, scaled. Head with appressed scales. Thorax not crested. Fore- wings elongate, narrow, apex obtusely pointed, termen obliquely rounded, dorsum somewhat excavate from vein 3 to i ; surface with large tufts of raised scales : neura- tion 1 2 veins ; 7 and 8 stalked ; 3 approximated to 4 ; 4 from angle of cell ; 5 closely approximated to 4, remote from 6 ; 11 from middle of radius ; 10 approximated to 9 ; media almost obsolete. Hindwings as broad as forewings, elongate-ovate, cilia rather long (i) ; i with costal fold containing an expansible subcostal hair-pencil : neuration 8 veins ; 6 remote from 5, gradually approximated to 7 at base ; 8 free, not connected with middle of cell by transverse vein ; 3 about equidistant from 2 and 4 ; 4 from angle of cell, 4 and 5 normally stalked, but sometimes connate or even separated by a small space ; discoidal weak ; media strong from 6 to base. Abdomen not depressed, $ genital segments well-developed ; % with ovipositor extruded. Legs, posterior tibiae clothed above with long dense hairs. Larva in a flattened case rounded at either end somewhat resembling an old- fashioned spectacle case ; feeding on rotten wood. The above description is largely copied from Meyrick (/. c.) but some additions and modifications have been rendered necessary after carefully studying a long series presenting considerable variation in the neuration of the hindwings. The series of Diplosara lignivora, Btl., consists of 48 (13 ^ + 35 ?) specimens; of these 23 (8 ^? + 15 ?) have veins 4 and 5 of the hindwings stalked, in some the stalk is short (almost connate), in others it is long or very long ; 7 (r ^ + 6 $) speci- mens have these veins connate in one wing and stalked in the other, the length of the MICROLEPIDOP TERA 647 stalk varying ; 8 (2 ^ + 6 ?) specimens have veins 4 and 5 connate in both wings ; 3 (?) specimens have these veins connate in one wing and very closely approximated in the other, while 7 (2 ^ + 5 $) have them very closely approximated in both wings. One specimen (28675, ?) from Kauai, belonging to the series with 4 and 5 connate, is teratological, with nine veins, 3 and 3^'' being stalked. These variations do not appear to be dependent on locality. The greatest variation is shown in the series of 27 from Hawaii (i2k;;7<;kJ;4<;4c:). Only 2 speci- mens were received from Lanai (i <; i <.<). The 7 specimens from Molokai do not vary, all being < Oahu 4 specimens (3 ^ ; i c). Kauai 8 specimens (2 <-<\ 4 < ; 2 c), in this series no specimen is >^ in both wings. Diplosara lignivora is very variable in size and appearance but such variation is individual and cannot be correlated with locality or with neuration. 322. (i) Diplosara lignivora, Btl. (PI.

This species differs from maculipennis, Crt., noticeably in the marking out of the veins on the costal half of the forewings by white lines, in which it agrees with rectivittella, Z., from Bogota, but from this species it differs in the presence of an angular excrescence at the upper edge of the white dorsal streak. If rectivitlella can rightly be regarded as a species distinct from the cosmopolitan macidipeiinis then albovenosa has at least equal claims, but as the ordinary form is undoubtedly associated with it in Hawaiia it is quite possible that the distinctions relied upon may prove to be merely varietal, since all the points of difference mentioned by Zeller in his description of the South American species appear to come within the range of variation exhibited by the common form. In a very lengthy series from wide geographical range I have found no variety of niaculipennis exhibiting the distinctly marked lines of veining on the costal half of the wing which characterise rectivitlella and albovenosa, F.

Legs, hind tibiae with densely packed closely appressed scales above. Eccoptocera comes nearest to Holocola. Meyr., but is distinguished by its notched antennae ; Heligmocera, Wlsm., differs in the antennae having a sinuation extending over several joints, instead of a notch, and veins 3 and 4 of the hindwings are stalked. Strepsicrates, Meyr., has a notch in the antennae, but it is at about one-fifth from the base, and veins 7 and 8 of the forewings are separate. Baikrotoma, Meyr., has a notch immediately above the basal joint of the antennae, but veins 7 and 8 oi the forewings are separate. Proteopteryx, Wlsm., differs in not having the antennae notched, in having veins 7 and 8 of the forewings separate and 3 and 4 of the hindwings stalked. All these 674 FAUNA HAWAIIENSIS genera have twelve veins in the forewings and possess costal folds in the t, others belonging to this group, e.g. Palaeobia, Meyr., are easily separable from the genera mentioned by the absence of the costal fold. The only allied genus which agrees with Eccoptocera in having only eleven veins in the forewings, a costal fold and notched antennae, is Hendecasticha, Meyr., but while Eccoptocera has 7 and 8 stalked and 6 obsolete Hendecasticha has 7 and 8 coincident — and therefore no stalked apical veins. The coincidence of veins 3 and 4 of the hindwings (an unreliable character among the species of these genera) appears to be maintained throughout the long series of Hawaiian specimens. 365.

This species is very closely allied to the European corticana, Hb., and so far as one can judge from a small series it is equally variable in colour and more variable in size. The females are all paler than the dark male above described, but some males are decidedly paler (than No. 28075) and show a tendency to greater suffusion and therefore obliteration of defined markings, the median streak being absorbed in the sufifused shading, the dorsal markings also being scarcely traceable. On the other hand the females tend to develop more clearly defined spots and blotches, varying rather in the degree of confluence between them than in the amount of general suffusion of the darker colouring over the wing surface — in one specimen the dorsal markings are con- fluent, forming a dark blotch which spreads across the wing to the costa. 379.

This species is so similar to Bactra lanceolana, Hb., in the variation of its colouring that a detailed description made from a single specimen could only be misleading. The ground-colour is for the most part pale fawn (certainly browner than the general idea of the meaning conveyed by the word ''stramineous " as used by Butler). The speckling along the costa and dorsum as well as on the disc and the slender lines indicating the pattern of the neuration (always more noticeable) are of a darker fawn- brown, or even fuscous tint, tending in some cases to blackish. The main feature of the variation is in the degree of insistence of a dark shade running from the base to the apex through the middle of the wing, in some specimens this is strongly marked, and is 88—2 688 FAUNA HAWAIIENSIS diffused downward nearly to the dorsum, in others it is entirely absent, but the spots at the end of the cell and at the basal third of the fold are nearly always recognisable in addition to the speckled appearance of the wing-surface, especially along the margins. In size the species also varies considerably (Exp. al. 14 — 34 mm.) as is the case with its European representative, and were it not for the uniformly greater length of the palpi one could scarcely hesitate to regard it as a mere geographical variety of our well- known Bactra lanceolana presenting some exaggerated forms approaching in the width of the wing the larger variety of this insect which has so frequently been suspected of special distinction.

Forty-six specimens. After examining a very long series of this species I find I can separate it from lanceolana, Hb., by one character only, viz., the comparative length of the palpi which in the European species are distinctly shorter. In all other respects the numerous varieties found in both regions can be absolutely matched. In company with others, at least equally competent to form an opinion, I have hitherto regarded straminea as inseparable from lanceolana, Hb., but if we admit the value of the longer terminal joint of the palpi, which certainly enables us to separate the Hawaiian from the European form, the name sti^aminea may be retained to designate this geographical and local race. When describing Chiloides, Butler called attention to the "separate emission of the second and third median branches " of the hindwings, this observation applies equally to very numerous specimens of our common Bactra lanceolana although not to all, and in the Hawaiian series exactly similar specimens from the same locality taken on the same day vary in this particular. Meyrick [Tr. N.Z. Inst xvii. 142 (1885)] has drawn especial attention to the identity of the New Zealand and Hawaiian species, and in redescribing Chiloides, Btl., (subsequently changed to Noteraula, Meyr.) he laid great stress upon the structure of the antennae, but a careful examination and comparison shows that in the Hawaiian examples they are uniformly shortly biciliate, whereas the New Zealand examples are biciliate from i — i^, the joints having also a more dentate appearance (*' antennae in MICROLEPIDOPTERA 689 male serrate, with whorls of moderate cilia," Meyr.). In describing the genus Badra from British specimens, Meyrick [HB. Br. Lp. 456 {1895)] uses the words "antennae in t moderately ciliated" in reference to lanceolana, Hb., from which the palpi rather than the antennae must be relied upon to separate the Hawaiian species. I have not felt justified in reversing Mr Meyrick's decision on the strength of so slight a difference but its permanence and uniformity throughout the series might not unreasonably be held to constitute a character of special value, and as I am unable to regard Noteraula, Meyr., as generically distinct from Badra, Stph., and CMloides, Bd., it would be appropriate that straminea, Meyr. (nee Btl.) should bear at least the varietal name Badra noteraula (n. n.). II. TORTRICINAE. % 44, Pararrhapttca, gen. nov.

Exp. al. (^) 20 — 28 ($)mm. Hindwings and cilia tawny brownish. Abdomen tawny brownish. Legs cinereous, with tawny brown shades and tarsal blotches. Type t (26312) Molokai, Mus. Wlsm. Var. B : the whole win^-surface is suffused with brownish fuscous, bedewed with shining, tawny bluish mottling, the hoary whitish ground-colour showing only in three costal patches, each interrupted by a dark spot on the margin, and in one smaller patch at the apical angle of the cell. Paratype % (26563) Maui, Mus. Wlsm. Var. C : the basal patch is bounded by an oblique white band, dilated towards the dorsum and interrupted by a dark costal dot ; there is also a pale patch on the middle of the costa interrupted by a dark spot, with three smaller pale costal spots beyond it, a small white spot also lies at the end of the cell. Paratype t (26566) Maui, Mus. Wlsm. Var. D : the pale markings are scarcely traceable, but are situated as in Var. C, although extending across the basal patch to the dorsum. Paratype Z (26385) Molokai, Mus. Wlsm. Var. E : the ground-colour is pale buff-brown and the darker markings are much mixed with rich chestnut-brown, especially visible on the upper halves of the basal patch and central fascia and in a costal patch at the outer third as well as in the apical cilia; the central fascia is connected at the tornus with the terminal suffusion which extends to the apex ; there is a distinct dark tawny fuscous spot at the posterior extremity of the thorax, but I can see no sufficient ground for separating this specimen from those above described although its general colour and appearance is somewhat dissimilar.

Forewings reddish brown, blotched or mottled indistinctly with shades of dark brownish ochreous and suffused with a thick sprinkling of shining, oHvaceous grey scales arranged in transverse lines towards the apex, the broad costal fold in the ^ having a somewhat richer tint than the wing-surface, tending to chestnut-brown : in Var. A a strong snow-white spot lies at the tornal angle of the cell (this is absent in Var. B, in which the brownish ochreous mottling is more distinctly visible in a large dorsal patch and on the outer end of the fold as well as towards the apex, the intermediate spaces inclining to tawny fuscous and therefore decidedly darker than the reddish brown of Var.

[i.e. Asychna, Stn.] its nearest ally was Oenophila N-flavwn, Hw. Staudinger (Berl. Ent. Zts. xiv. 325) regarded Opogona as intermediate between Bucculatrix, Z. and Phyllobrostis, Stgr. Staudinger and Rebel (Cat. Lp. Pal. 11. 220) place Opogona in Lyonetiadae between Bucculatrix and Opostega, thus following Staudinger and Wocke (Cat. Lp. Eur. 335), but removing Opostega from the N epticulidae to the Lyonetiadae, MICROLEPIDOPTERA ^ , . Walker placed his genus Cachura at the end of the Lyonetiadae following Bucculatrix, with Leucanthiza, Clms., intervening. Stainton described Lozostoma as one of the Elachisiidae allied to Cosmopteryx, Hb., \Lo20stoma (t Loxostoma) is invalid being homonymous with Loxostovia, Biv. (1838) Moll^^, Meyrick (Pr. Lin. Soc. NSW. xxii. 415) followed Stainton in referring Lozostoma to the Elachistidae which he defined as having ''Maxillary palpi rudi- mentary," but Opogona dimidiatella, Z., zx\^ panchalcella, Stgr., Lozostoma flavofasciata, Stn., and sterodyta, Meyr., etc., Cachura ol)jectella, Wkr., Argyresthia (?) aurisi]iiainosa, Btl, and various Malaysian and Australian species all agree in having the maxillary palpi strongly developed and folded. It therefore follows that Opogona, Z. {^Lozostoma, Stn.) is approximately correctly located in the Tineidae in the neighbourhood of Opostega, Z., while its nearest ally is perhaps Dendronettra, Wlsm. (Pr. Z. Soc. Lond. l8gi, 509—10, PL XLI. 6) which is apparently an older and less specialised form than either Opogona or Opostega. Opogona aurisquaniosa, Btl., has been bred from sugar-cane and banana in Hawaiia and subcervinella. Wkr. (n. %yn.=^plu7nipes, Btl.) is noted as injurious to developed sugar-canes and in potatoes and other stored tubers in Mauritius. Unfortunately we have no exact record of the habits of either species, but van Deventer [Tijd. Ent. xln'ti. 83 — 4' PI- X. 1^-^(1904)] figures and describes the larva of Opogona fiiviiceps, F. & R., feeding on the Kokos-palm in Java. Meyrick [HB. Br. Lp. 728 (1895)] remarks of Opostega '' Larva almost unknown," which sums up concisely the present state of our knowledge of this genus. Stainton [Ent. Ann. 1868, 133] mentions the breeding of a crippled specimen of Opostega auritella, Hb., from flower-stalks of Caltha palustris by Sleich, and Buttner [Stett. Ent. Ztg. xli. 468, No. 2966 (1880)] records the breeding of a second cripple by Knaack from the same plant. Warren [Ent. Mo. Mag. xxv. 145 (1888)] states that he had by chance bred two specimens of salaciella, Tr. (these apparently fed among the flowers, or in the flower-stalks, of Rumex acetosella) and suggests that crepus- culella, Z., may feed in Mentha palustris, and spatulella, HS., in the flower-stalks of Wych-elm. 416.

Seventeen specimens. The larva makes a slender tortuous mine, in which the frass is disposed in a con- tinuous thread along the middle, in the upper side of leaves of (?) This mine commences sometimes at the mid-rib, sometimes at the outer edge of the leaf and terminates in an ovate blotch equal to about one-fifth of the width of the leaf itself in such specimens as I have before me (27968 — 70). Its habits appear to be most similar to those of coffeifoliella, Ntnr., and latifoliella, Mill. & Rgt Mr. Perkins who bred this species in Kauai made the following note " bred from blotch, or mine and blotch combined, on various plants, v. 1895. Pupa butterfly-like, living in web on leaves." He also found it (apparently the imago) ''on the leaves of a berry -bearing plant called 'Kikania'" in Oahu. There is obviously some error of observation in Mr. Perkins' notes, the larvae of some other Tineid must have been collected inadver- tently with those of G. marginestrigata. 429.

M rt ^ " " ^ * * * * * * * * * * * * Crocidosema plebeiana, Z., Trichoptilus oxydactyhis, Wkr., and Setomorpha rtdella, Z., are widely distributed, and probably not artificially introduced. Plutella maculipennis, Crt., is universally distributed, feeding on cabbages and other Cruciferae. It is difficult to determine the natural range of this species which F. H. I. 97 75^ FAUNA HAWAIIENSIS has undoubtedly been extended by commerce — only if the larva feeds on no native Crucifer in Hawaiia would it be possible to demonstrate that the insect has been intro- duced, although probably this is the case. Bedellia somnulentella, Z., and minor, Busck— These species feed on Convolvulus and Ipomoea ; the former is widely distributed, the latter, which has been recently differentiated, was hitherto only known to occur in Texas. Two endemic species of Bedellia are found in Hawaiia, and others in Australia, it is therefore possible that these two have not been artificially introduced, Phthoriniaea operctilella, Z., mines the leaves of Tobacco, and bores into the tubers of the Potato, causing serious damage. It is now widely distributed, and carefully weighing the evidence deducible from the long list of references given under this species (pp. 483 — 4), it would appear to have originated in the United States, where it feeds also on other Solanaceae, and was doubtless introduced to the Islands via San Francisco. Gelechia gossypiella, Sndrs., is noted by Mr. Perkins as an introduced species, highly injurious to Cotton, at Honolulu ; it is recorded from India and Japan, but is not known to occur in America. Tinea fuscipunc tell a, Hw., Monopis crocicapitella, Clms., Monopis monachella, Hb., Endrosis lactella, Schifif, and Oecia niactdata, Wlsm., are domesticated species, doubtless introduced by commerce, Oecia maculata, hitherto only recorded from Brazil and the West Indies, is common in houses, having the same habits as Endrosis lactella — it probably ranges through Central America (a second species occurring in Costa Rica), and was not improbably introduced to the Islands from San Francisco, where it will doubtless be found. The American Monopsis crocicapitella, Clms., is now recognised as identical with a European species disguised under the synonyms hyalinella, Stgr., lonibardica, Hrng., and heringi, Rdsn. ; this also occurs in Tenerife. Archips postvittamis, Wkr., is certainly an importation from Australia, where it is common and very variable ; Mr. Perkins also notes its occurrence in New Caledonia. The late Francis Walker established a record when dealing with specimens of this species, describing them under 1 2 different idionyms distributed among 4 genera in two subfamilies of the Tortricidae, Ereunetis minuscula, Wlsm., is from the West Indies (and probably Colombia), while E, simulans, Btl., occurs in the Marquesas and Fiji — other species are found in Australia, and allied genera in Malaysia and Africa, it would therefore appear that these forms are widely distributed, and it would be rash to assume that they have been introduced. Platyptilia fuscicornisy Z., only hitherto recorded from Colombia, is probably more widely distributed, but confused with cosmodactyla, Hb., and acanthodactyla, Hb., this may, or may not have been introduced — evidence is wanting. Stoeberhinus testacetis, Btl., Opogona aurisquamosa, Btl., and Ej^eunetis simulans^ MICROLEPIDOPTERA 759 Btl., are Pacifican forms, all occurring in the Marquesas, atirisquamosa in the Society Islands, and simulans in Fiji. The distribution of the remaining two species is peculiar, Stag7natopho7'a Jionorariella, Wlsm., occurring in Pitcairn Island, while its close ally Stagmatophora qiiad^H fas data, Wlsm., is found in New Guinea. Ethmia colonellay Wlsm., although not yet recorded elsewhere, has almost certainly been imported from Malaysia, but so much error has been introduced under the name ''hilarella, Wkr.," which was the original record of this species from Hawaiia, that great caution is needed in tracing its derivation. Let it be noted that there are several yellow hind-winged forms of Ethmia allied to colonellay very closely related to each other, but distinct, and that ^bicolorella, Pgnstk. (nee Gn.), from Malaysia, appears to be identical with colonella. DESCRIPTION OF PLATE X. (VOL. I.) MICROLEPIDOPTERA, PYRALIDINA. PTEROPHORINA, ORNEODINA, TINEINA—TORTRICIDAE.
