354 CHONDROSOMA: APOCHEIMA: POEOILOPSIS. By J.. B. Pbout. 



Jarva is brown mottled with ferruginous, frequently with V-shaped ochreous dorsal marks on the 2nd and 

 3rd abdominal segments. Polyphagous on trees. Moth in January- — March, sometimes even in December, 

 well protected on the tree-trunks on which it rests. Central Europe to the Ural, very common. 



sinuosaria. PH. sinuosaria Btlr.(l9c). Very similar to large pet^ana, the cells longer, lines rather sharply expressed, 



postm^dian of fore wing sometimes crossing the cell-spot, then strongly incurved so as to touch the middle 

 line on the fold, first 2 lines of hindwing placed further from base, etc. Japan;? Ussuri district. 



verecunda- PH. verectuidaria Leech (19 c). More slenderly built than the two preceding, more whitish, without 



na. olivaceous admixture, recalling weakly marked titea Cram., from N. America. Japan, only one example known. 



104. Genus : Choudrusoma Anker. 



Head, body and legs exceedingly shaggy-haired. Eye small. Antenna in ^ bipectinate to apex, with 

 long, thick branches. Abdomen in (J short, stout, rather obtuse, .spinose. Hindtibia Avithout median spurs. 

 Wings relatively shorter than in the succeding genera. Eorswing with 1st — 2nd subcostal comcident, free. 

 Hindwing with 2nd subcostal stalked with 1st radial (very variably); 2nd radial very slender. $ wingless, 

 hairy. Only one species known. 



fiduciaria. C. fiduciaria Anker (19 b). ^ wings rather thuily scaled. Known at once by the shape and by th^ 



white patches in and behind the cell. $ uniform dark brown. — The larva is said to be smooth, green, with yellow- 

 ish lateral stripe. On Euphorbia. Lower Austria, Hungarj' and the Tarbagatai district. October — November. 



105. Genus : Apoclieinia Hbn. 



(^ longer-winged than Chondrosoma, cells longer (though rather long \n all this group of genera), 

 forewing with 1st and 2nd subcostal separate. Thorax broader. Abdomen spinose. Eye normal. Only 4 species 

 known, and even these doubtfully congeneric. One is South African. 



Mapidaria. A. hispidaria Schiff. (= ursularia Don., tauaria Newm.) (19 b). cJ forewing brown, dusted and clouded 



with dark fuscous, thus coloured nearly as in the (J of Lycia hirtaria, from which it differs in its smaller 

 size, narroT\'er wings, paler and differently marked hindwing, etc. Ai'ea distaUy to postmedian line of fore- 

 wing generally pale, sometimes strikingly contrasted. 2 similar to that of Phigalia pedaria but largey and with 

 obscura. more hairy legs, venter and antenna. — ab. obscura Kidine has the body and wings almost uniform brown- 

 cottei. black. — cottei Ov.. from Digne, is larger, more robust, clearer grej^ (not mixed with ochreous), the markings 

 sharply black. — Larva similar to that of Phigalia pedaria but with the humps less developed and without 

 the ochreous V-shaped dorsal marks: variable in colouring. On oak and occasionally birch, ha-wthorn, etc.. 

 May — June. Mot.h in February — March, rather local in Central Europe, Italy, the Balkans and Dauria. 



cinerarius. A. cinerarius Ersch. (19 b). Less yellowish grey-brown than hispidaria, easily distinguished by the 



position and angulation of the dark lines. Hindwing longer and narrower. Antenna, as in hispidaria, yellow. 

 Zerafshan, Ferghana. Issyk-kul and Hi. 



106. Genus: Poecilopsis. Harrison,. 



Middle and hind tibiae \\ith the spurs very slender and short, sometimes almost obsolete. The hairy 

 clothing of head, body and legs stronger than in Nyssia, including (as in Apocheima) the $ antenna. Wings 

 more thinly scaled, semitransparent. ,^ foreAving with 1st and 2nd subcostals stalked, their stalk commonly 

 longer than in Nyssia. <? genitalia with ..gnathos" larger and broader, although more pointed, than in the 

 allied genera, not indented at the base; ,, vesica" with a band of extremety strong ,,cornuti". $ wings more 

 pomted than in Nyssia, with longer hairs. Larva less smooth and cylindrical than in Nyssia, 8th abdominal 

 segment with 2 well-developed warts. Pupa not so stout as in Nyssia. Only 3 or 4 species known, Palearctic 

 and Nearctic. 



pcrnonaria. P. potTionaria Hbn. (= ? grisea Thnbg., vertumnaria Lef., stigmatclla Zett.) (19 c). Wings narrow, 



the frmges white or whitish, strongly dark-chequered. Thorax and abdomen not quite so robust as in lapponaria. 

 with a strong admixture of whitish hair. Collar white. Legs ringed with white. Ground-colour whitish grey, 

 with the veins blackish and a sprinkling of orange scales. 2 blackish with an admixture of orange scales, 

 the hairs grey. The larva is yellowish grey \\ath orange-yelloM' collar and segment-incisions and blackish sub- 

 dorsal and lateral spots. On oak, fruit-trees, etc. The moth appears in March and April and is local in Central 

 helenae. and North Europe (except England and Holland); ? Asia Minor. — hybr. helenae Harrison (pomonaria S 

 X N. zonaria $). (j^ very like zowana but more ochreous, the blackish lines and suffusions not so clearly marked.
