AMNESICOMA; PHILEREME. By L. B. Prout. 



markings purer and more extended, the costal blotch being large and broad, the antemedian usually well- 

 developed and the apex more definitely white-marked. W. China; also as a rare aberration in the N. W. Him- 

 rivularia. alayas. — rivularia Leech, from Omei-shan, is rather darker and more richly coloured than the type form, 

 the white costal mark nearly as in that, the postmedian line conspicuous, broader than in the other forms, 

 the apex scarcely whitish; hindwing whitish, with a dark marginal band of equal breadth (about 3 mm) and 

 postmutata. intensity throughout, fringes chequered. Underside sharply marked. Possibly a distinct species. - postmutata 

 suhsp. 1100., which may also be a distinct species, has the forewing coloured nearly as in the hidian type, but 

 somewhat transitional towards penguionaria, the white costal patch reaching to the middle of the wing, but 

 throughout obscured by grey dusting; the hindwing white (rather clearer than in rivularia) with a dark border 

 nearly as in that form. How-kow, Tibet; also one example from Omei-shan. Rather larger than rivularia. 



penguio- 

 naria. 



Ph. penguionaria Oh. (6 1) differs from amplicata in the complete loss of the white costal patch, almost 

 the only white marking which remains being the dentate shade (sometimes reduced to a row of dots) distally 

 to the postmedian; veins a good deal marked with bright ochreous. Hindwing rather more uniform than in 

 amplicata, nowhere extremely dark; one or two wavy lines present. Under surface rather uniformly dusted, 

 forewing without white apex; postmedian line of both wings rather less angled behind 3'''* radial than in ampli- 

 cata. Ta-chien-lu and How-kow, Tibet, reaching elevations of over 3000 m. 



tonohignea- 

 ria. 



Ph. tonchignearia Oh. (6 1, as bicolor; 9 h) is somewhat smaller than amplicata, with rather more curved 

 but less oblique distal margin, the forewing therefore appearing rather shorter and more rounded. The subbasal 

 line of the forewing runs more obliquely towards the hindmargin, the antemedian projects less strongly distad 

 behind the median vein; the hindwing both above and beneath lacks the postmedian line, being clear white, 

 with smoky suffusion at base and narrowly along inner margin and a more sharply defined blackish border 

 than even in rivularia. The white costal blotch in the middle of the forewing is extremely variable in 

 development. Forewing beneath with smoky proximal half and a broad blackish distal border, the latter 

 preceded by a black mark on the costa and containing a sharply defined white apical spot. W. China, Tibet 

 and Kulu. Hampson and Leech have sunk this species to the Indian Amnesicoma bicolor Moore, to which it 

 bears an extraordinary resemblance but which differs in the generic characters, tonchignearia being a typical 

 Photoscotosia. 



alhomacu- Ph. albomacularia Leech (1 1 g) is easily distinguished from tonchignearia by its much broader dark 



laria. border, both above and beneath. The wings are slightly longer (approaching amplicata). Omei-shan, July, 

 only one example known. 



48. Genus: Aiiiuesicoiua Wa 



rr. 



Habitus and general characters of Photoscotosia but the forewing without hair-pencil, the hindwing 

 with anterior margin and costal vein less strongly curved. 



Only 3 species are known, inhabiting India and Tibet. It forms a transition between Photoscotosia and 

 Cidaria and might probably be united with either, according to the weight attached to particular characters. 



nuncupata. A. nuncupata PUng. Very near Photoscotosia leechi in size and markings, the colour more red-brown, 



especially in the median area, the distal edge of which is not so distinctly dentate; underside less glossy, 

 dusted with grey, darker, especially the hindwing, which shows a distinct cell-spot. Occurs together with 

 leechi in the Koko-nor district, end of July. 



49. Genus: Philereme Hbn. 



This genus, often called by Stephens's later name of Scotosia, is doubtfully tenable, as it only differs 

 from Triphosa in the cf genitalia, which show enormously developed anal clasps. 



Larva and pupa similar to those of Triphosa and Calocalpe, the larvae sometimes feeding exposed, 

 sometimes spun up in leaves. 



Distributed in the Palearctic Region. 



vetulata. Ph. vetuiata Schiff. (^ ? undulataria Hufn., affectata Ev.) (8a, b). Shiny grey-brown, both wings 



traversed by numerous slightly darker wavy lines, which are angulated subcostally on the forewing; both 

 wings with blackish discal dot above and beneath. I have never seen really banded specimens; ixiAQeA vetulata 

 generally varies very little. It inhabits Central and North Europe, parts of Siberia and Transcaucasia. —
