14 ACRONICTA. By W. Warren. 



preceding species, by Gkaesek in Amurland, who gives the larva as dark green, sparsely clad with short- 

 brown bristles, thickened at their tips: fullfed in autumn, on oak. 



centralis. A. centralis Ersch. (2h). Forewing ashy grey, with black lines and stigmata, and a fuscous shade 



beyond outer bne; recorded from Central Asia. 



consanguis. A. consanguis Btlr. (3i). Like pntinosa Guen., but larger and paler: at present only known from Japan. 



cuspis. A cuspis Hbn. (21a). Like A. psi L., but paler, bluer grey; the black streaks thicker; stigmata 



united by a short black bar: occurs sparingly throughout Europe and in Western Asia, but not recorded 



from England. — Larva like that of psi, but the fleshy process on segment 5 bears a long tuft of black 



leucocuspis. hairs; it is fullfed in autumn, living on alder only. — leucocuspis Btlr., occurring in North China, Japan 



taurica. and Corea is larger and darker in tint. — taurica Stgr., on the contrary, is a much paler form, with the 



stigmata far apart, queried by Staitdinqee as possibly a distinct species. 



digna. A. digna Btlr. (= michael Oberth.) (2 i). Forewing pale grey in the cT, darker in ?, with a thick 



black streak from base: median shade broad, bent in middle; hindwing dull whitish. Occurs in Amurland, 

 Japan and Corea. 



eleagni. A. eleagni Alph. (2i). Differs from aceris in having the thorax and forewing tinged with luteous, 



the normal markings tending to become obsolete; recorded from Bokhara. The larva, which does not seem 

 to have been described, is said to feed on Eleagnus hortensis. 



fasciata. A. fasciata Moore (2i). Like strigosa F., but larger and darker, more coarsely scaled; a broad black 



divisa. streak, interrupted in the ab. divisa Moore, runs along submedian fold; hindwing brownish fuscous; 

 originally described from India , but occurs also in China and Japan , in Kashmir and Burma , and with 

 slight local differences also in the Kei Islands, New Guinea and North Australia. 



gastridia. A. gastridia Swinh. (2i). Forewing pale grey, with ill-defined markings; inner margin of hindwing 



and the abdomen fulvous - tinged ; this species in the first instance recorded from Murree, N. W. India, 

 extends northwards into Kashmir. 



hemileuca. A. hemileuca Bung. (2k). Like strigosa F., but larger; forewing darker, reddish grey; hindwing 



pure white: found at Kuku Nor, Tibet. 



hercules. A. hercules Fldr. (= elongata Oberth.). One of the largest species of the genus, closely resembling 



the North American luteicoma Guen.; found in Japan and Amurland. The larva is describe! by Gkaesek as 

 short, thick, and chestnutbrown in colour, sparingly clothed with glossy black bristles, the tips of which 

 are slightly clubbed, and having a very large, shining black, head ; fullfed in autumn, on elm, resting, like 

 others of the genus, in a half-coiled position on the upper surface of the leaf. 



intermedia. A. intermedia nom. nor. (= increta Btlr. nom. praeocc.) (2 k). Like tridens L. but consistently larger, 



with more uniformly dark grey forewings; the stigmata united by a black dash; the tibiae and anal seg- 

 ments of abdomen laterally streaked with black : occurs in Japan , Corea and West China , and is surely 

 distinct from tridens. 



jankowskii. A. jankowskii Oberth. (2k). Forewing pale grey, with a dark central fascia forked at costa; hind- 



wing of d* whitish, of ? wholly brown. This is a small species, found in Amurland and Japan, somewhat 

 like sinens Wlk. 



kaighalika. A. karghalika Moore. Like tridens and with similar markings, but darker; the basal black streak- 



shorter, and the interval between the two lines wider. Karghalik, Yarkand. 



leporina. a. leporina L. (3a). Forewing white, the lines indicated by black spots; fairly common in May 



and June throughout Europe, in Armenia and Amurland. Larva pale green, or yellowish, with long silky 



white hairs, which are also sometimes yellowish, curling over the sides; fullfed in autumn; on alder and 



bradyponna. birch. — ab. bradyporina Tr. (3a), occurring in N. Europe and the commoner form in Britain, has the 



semwirga. wings dusted with grey, and the markings more developed. — ab. semivirga Tutt has the outer margin of 



teporella. forewing broadly grey. — In leporella Stgr. (= cineracea Graes.) (3 a) confined to Eastern Asia and Japan, 



rosea, the forewing is greyish white with indistinct markings. — ab. rosea Tutt (= la rose Engr.) is said to have 



the forewing and the segmental incisions of abdomen of a bright rose colour. 



leucoptera. A. leucoptera Btlr. Forewing like rumicis; hindwing white, with base and inner margin brown. 



and a broad black outer border; a Japanese species, which Leech sinks to longa Guen. from N. America. 



A. ligustri F. (3b). Forewing purplish fuscous, more or less greenish-tinged, with a paler patch 

 beyond cell; prothorax conspicuously whitish. — Snellen makes this species the type of his genus Cra- 

 niopkora, because the dorsal segments are all tufted. Widely distributed, but not abundant, throughout
