NOVITATES ZOOLOQICAE XXII. 1915. 325 



Discomiosis gen. nov. 



Face smooth. Palpii.s short, shortl\- rough-scaled. Tongue pre.sent. Antenna 

 in c? with short, veiy slender pectinations, which are well ciliated and surmounted 

 witli fascicles of long cilia. Femora glabrous. Hindleg with femur, tibia, and 

 tarsus about equal in length ; hindtibia of tj with strong hair-pencil and a pair of 

 terminal spurs ; near to them a rather larger, compact, spur-like tuft ; in ¥ with a 

 pair of terminal spurs and one proximal (in crescentifera both). Forewing with 

 termen smooth, oblique, gently curved ; areole double, >SC^ arising from cell ; SC' 

 from posterior wall of distal areole, seldom near its apex ; \i" from very slightly 

 before middle of DC! ; M' sejiarate. Hindwing with termen typically somewhat 

 sinuous and snbcrenulate ; SC^ very shortly stalked with R', sometimes connate ; 

 M' separate.

32. Discomiosis anfractilinea sp. nov. 



$ ? , 23-26 mm. Face and palpus black, the latter pale beneath. Vertex and 

 antennal shaft pale ochreous brownish. Thorax and abdomen concoloroas with 

 wing.s, the abdomen dorsally with two or three blackish belts on the anterior 

 segments. 



Forewing pale ochreous brownish, sometimes with a slight olivaceous tinge, 

 sometimes more pinkish ; scattered fuscous irroration ; lines blackish fuscous, 

 thickened at costa, deeply (the postmedian nnusnally deeply) inangled behind C, 

 strongly and acutely projecting distad behind SC and more or less strongly zigzag 

 throughout their course, at costa and hindmargiii ajiproximately equidistant ; ante- 

 median and postmedian generally fine and sharp, the latter with some long proximal 

 teeth between the veins ; median shade weaker and broader, outbent so as to pass 

 far distally to the discal dot, which is minute but sharji; subterminal dark dashes 

 and strong terminal black dots, both between the veins ; fringe dark-spotted opposite 



the veins. Hindwing with discal dot surrounded by a slightly raised oval white 



ring, of which the posterior part is sometimes almost obsolete (as in Acidalia 

 cxiguaria AValk. xxi. p. 368, nee Swinh. Tr. Ent. Soc. Lond. 1904, p. 560) ; a 

 median dark line closely following this ; postmedian line, distal area and fringe 

 about as on forewing. 



Under-surface very weakly marked, but scarcely glossy ; forewing slightly 

 snffnsed, hindwing paler, both with discal and terminal dots and traces of post- 

 median line ; fringe weakly spotted.

33. Discomiosis synnephes sp. nov. 



(? ?, 19-21 mm. Face and palpus blackish fnscons, the latter somewhat paler 

 beneath. Vertex and antenna pale. Body and legs concolorons with wings ; fore- 

 coxa and femur partly infuscated. 



Forewinq rather glossy, light brown, variable in colour (the type $ much more 

 ochreous, the ? duller, more greyish), the distal area throughout shaded with blue- 

 grey ; antemedian line almost entirely obsolete, sometimes discernible at costa;
