274 ENTEPHRIA. By L. B. Prout. 



23. Genus : £iitei>hria Hhn. 



(See Vol. 4. p. 234; SuppL-Vul. 4. p. 137.) 



An essentially Palaearctic- gemis of chiefly iiiountain Larentiines. with the forewing-pattern adapted 

 to the coloration of tlie rocks on which they rest. Extenial cliaracters nearly as Coenotephna, except that in 

 a few species the discocelkilars are not biangulate. The only scientific groiinding of the genus was given by 

 Chatman in 1908. who demonstrated the taxononiic value of the "juxta" and "ealcar" of the ,^ genitaUa in 

 separating this from other alpine species of siniilar facies ; until tliis has been tested in all the outlieis, it cannot 

 be asserted that our Classification of them is accurate. 



ravaria. E. ravaria Led. (Vol. 4. \A. V.i n). A lather large and glossy species, distinguishable froni the niost siniilar 



Entephria by the non-biangulate discocellulais of the hindwing. The forewing has not, in any example known 

 to me, such strong colonr contrasts as in our figure. Chiefly S. Siberian, but 2 large Kashmir ,^,^ (Koksar and 

 Rala) seera to agree well. 



jusairkt. E. fuscaria Leech (Suppl.-Vol. 4. pl. 13 e). A rather obscure grey species with darker basal patcli and 



median band, otherwise weakly niarked. Antennae broken in the miique type, but the short pieces which reniain 

 become strongly dentate. Hindwing with termen waved, discocellulars simple, 2nd radial arising mnch before 

 the middle. Ta-tsien-lu. 



pol'wtaria. E. poliotaria Hmps. (Vol. 4. pl. 13 n). A true Entephria by all characters, smaller and darker than the 



Palaearctic cyanata Hbn., not so glossy as nobiliaria H.-Sch., hindwing whitish grey, with cell-dot and on the 

 underside indications of postmedian line. Kashmir and Chobia. 



ncurbüKüi-ia. E. neurbouaria Oberth. (Vol. 4. pl. 9 k). Unmistakable in the bright green tint and brown markings. 



The whitish hindwing. both above and beneath, has markedly punctiform lines. By the genitalia not a trne 

 Entephria. Szecluian and N. Tibet, the type from Ta-tsien-lu. 



iiidrifoKcia- E. tiigrifasciaria Leech (Vol. 4, pl. 7 i). founded on a J* from Pu-tsu-fong. has a somewhat more crenulate 



'"'• and sinuate hindwing than most Entephria. Grey with blackish median band and a deeply dentate blackish 

 line beyond it. Antenna simple, retinacidmn rather large; perhaps akin to Triphosa. 



stellata. E. Stellata Warr. (= adjrouaria Oberth.) (Vol. 4. pl. 10 i). Thorax and forewing mixed fuscous and olive- 



yellow and marked with b 1 u e - w h i t i s h , nearly all the latter markings punctiform, the lunulate sub- 

 terminal nearly complete. Hindwing beneath. from cell-dot outward, traversed by alternate brownish and 

 white waved lines. Tonglo, Sikkim, 10 000 feet (loc. typ.) and through Tibet to Szechuan; also in Kashmir. 

 This, too, is no true Entephria, but its actual affinities have not yet been ascertained. 



arficntipiwm- E. argetitiplumbea Hmps. (Suppl.-Vol. 4, pl. 17 c). Small for an Entephria and unusually glossy, with 



hea. whitish hindwing, rather strongly marked on the underside. Face somewhat prominent, nearly smooth, almost 

 white. Moderately variable, but not closely like any other known species. Indian Tibet, up to 12 000 feet; 

 also known from Bhotan. Sikkim and Kashmir. 



iiuMckttis- E. punctatissima Warr. (27 e). Perhaps (as Elwes, in coli., suggested) near caesiata Schifj. (Vol. 4, 



*"""• pl. 9 f). Palpus longer (over 1^4). Slightly rounder-winged ; median band of forewing broader, bounded on each 

 side by large white vein-dots; subterminal also conspicuously punctiform; the thick black pairs of terminal 

 marks alternated (between the veins) with white spots. Sikkim, at high elevations; discovered on the Nepal 

 frontier, 10 000 — 12 000 feet. E. poliotaria, which shows also a tendency towards punctiform markings, is smaller, 

 more blue-grey, the median band more narrowed posteriorly, the subterminal line more continuous. 



nndfwava. E. multicava sp. n. (27 f). Siniilar to the largest, greyest pi(7icfatissi')na. Palpus somewhat shorter 



(scarcely l]^), more heavily scaled. Abdomen with white dorsal spots very conspicuous. Forewing with termen 

 less curved; cell-spot somewhat enlarged; white spots in part still better developed, all the 3 rows between 

 median band and subterminal well formed, the third (nearest the subterminal) niucli more so than in punctatis- 

 sima, tliough a little irrorated with grey; Ist j^ostmedian dark line more strongly outbent opposite the cell- 

 spot; the white subterminal dots, especially the large one of cellule 3, set on well-defined black wedge-marks. 

 Hindwing slightly more elaongate than in pHyicfatissima . the cell-dot, postniedian line and subterminal shade 

 well developed both above and beneath. North Burma: Adung Valley, 12 000 feet, 28 September 1931 (Lord 

 Cranbrook), 1 $ in the British Museum. 



iitirii/iiifa. E. aurigutta Prout (Suijpl.-Vol. 4. pl. 13 g). Only the type $ known, collected on Mount Omei at 11000 



feet; in this the areole is undivided, but in all eise it seenis so typically an Entephria that I suppose the venation 

 to represent a "sport". In its dark slaty-grey colouring and tiie developnient of a pale postmedian band on the 

 hindwing it rivals or surpasses the darkest form oi ravaria Led.. or it might be likened to a dark form o\' flari-
