MIGHOBISTON: SEBASTOSEMA; ZAMACRA. By L. B. Prout, 357 



hairy, the pair of spurs moderately long. Forewing with 1st — 2nd subcostal coincident. I know only the ^. 

 The single species is E.' Palearctic. 



N. lefuarius Ersch. (= olgaria 06., inaturaria Ghr.) (19 e). Recognizable at a glance by the fuscous leiuarius. 

 borders and the characteristic pale area from base of forewing to near its apex, very light ochreous brown or 

 in its posterior part white. S. E. Siberia, China and Japan. 



111. G6nus: Microbistoii ^tgr. 



Similar to Chondrosoma, abdomen less strongly (if at all) spinose, -less densely hairy, antennal pectina- 

 tions more slender, hindtibiae apparently with all spurs, forewing even shorter, all veins present, cell of 

 hindwing longer, 2nd subcostal scarcely stalked. Only the following species known. I believe the above cha- 

 racters are correct, but I have no material for dissection and the extreme hairiness renders examination 

 difficult. 



M. lanaria Sv. (= tartaricus Stgr.) (19 e). Forewing of (^ coloured about as in hispidaria, the lines lanaria. 

 black, often only the postmedian well-defined, blackest (spotted) at costa and principal veins, terminal region 

 pale. Hindwing paler, with dark antemarginal band, postmedian line broken into a few spots or almost 

 obsolete. Underside similarly but somewhat more weakly marked, hindwing with distinct cell-dot. Ural 

 and Central Asia, March — ^April; ? E. Siberia. 



M. turanicus Stgr. is perhaps merely a larger, darker variety of the preceding. ForeM'ing dark brown- iwamo-us. 

 grey with 4 partly obsolete blackish lines, hindwing somewhat lighter, dirty grey, mostly with dark discal 

 dots; both wings beneath with 2 distinct dark lines, which are more or less completely wanting in lanaria. 

 Transcaucasia. 



112. Genus: ISebastosema Warr. 



Palpus short, hairy. Tongue obsolete. Antenna in ^ bipectinate to apex. Body and legs haii-y. Fore- 

 wing with 1st — 2nd subcostal coincident, arising from a minute areole. Hindwing with costal vein rather 

 far from cell, connected by a slight bar about the middle, 2nd subcostal short-stalked, 2nd radial wanting. 

 9 unknown. Established for a Japanese species of very distinct appearance but evidently related to the Biston 

 group, though the cells are scarcely more than one-half the wing-length. 



S. bubonaria Warr. (19 e). Unlike any other species. Forewing violet-grey with large, round cell- hubonoria. 

 mark, black postmedian line and ferruginous submarginal band. Hindwing orange, darker distally, median 

 and postmedian lines black. Japan. 



113. Genus: Zamacra Meyr. 



Face rough-haired, with triangular horny projection. Palpus long-haired. Tongue rudimentary. An- 

 tenna in (J plumose. Pectus and femora densely long-haired. Hindtibia with terminal spurs only (except 

 excavata). Forewing long and narrow, costa .straight, 1st — 2nd subcostal coincident, anastomosing with costal. 

 Hindwing very narrow, especially in the $, costal margin gently concave, 2nd subcostal stalked, 1st median 

 stalked. Larva with strong spines, mostly 5 pairs to a segment, the dorsal pair largest, those on the 6th 

 andJTth abdominals slight. The moth rests in a very curious position, with the forewing rolled up and erected. 



ff A. Hindtibia with2spurs (Zamacra). 



: -1 ■' Z. flabellaria Heeger (19 f). Brown-grey with darker irroration, cell-spots and lines. Apex of hind- flabellaria. 

 wing very acute. Larva green, with oblique pale subdorsal markings, the spines rose-colour. On Calendula, 

 Senecio, Chrysanthemutn, etc., fond of the flower-buds. Pupa stout, cremaster extremely blunt; somewhat 

 rugose but strongly glossy, yellow brown with abdomen more reddish; in a strong earthen cocoon. Moth in 

 the early spring, perhaps again later. Local, S. Europe and N. Africa to the Caspian Sea. 



Z. diaphanaria Piing. The $ differs from that of flabellaria in having more strongly projecting antennal diaphana- 

 joints. Both sexes with the wings slightly broader distally, the margin more strongly crenulate. that of the '"'"■ 



forewing less extremely oblique, 1st median vein not stalked, colour browner, 1st line of forewing more regu- 

 larly curved or bent, followed by some pale shading, median shade broad, forked anteriorly, the space between 

 this and the outer shade on both wings whitish, thinly scaled. Askhabad and N. Persia. 



Z. juglansiaria G/aes. (= albofasciaria Leech, '! okamotonis Matswnura) (19 e). Different in colouring, juglansia- 

 bright red-brown with whitish postmedian band. Apex of hindwing less acute than in the two preceding. '"*"" 



The larva was said to have been found on Juglans mandschurica, but as it was compared with that of Abraxas 

 grossulariata some confusion must have occured. Ussuri district and Japan.
