176 Mr. W. Warren on new 



band projects basewards slightly at anal angle of fore wings 

 and decidedly in the hind wings, the first part of the outer 

 line running to its angle and forming the edge of the fuscous 

 border to the anal angle. Underside yellowish. Abdomen 

 and thorax with patagia yellowish ; head and collar fuscous. 



Expanse of wings 20 mitlira. 



Several from the Khasias. 



Lasiacme, gen. nov. 



A development of Marasmia^ Led. ; like it the male fore 

 wing has a large fovea in the cell, covered with a flock of 

 hair above, and containing woolly hair beneath ; but the 

 present genus is characterized by the length of the abdomen 

 in the male and by the presence on the apex of hind wings 

 of male of a bed of hair-like scales on the upper surface. The 

 neuration is inconstant ; in one species the second subcostal 

 is free and closely approximated to the stem of the third and 

 fourth, in the other it is stalked with them ; so that, if neura- 

 tion alone were followed, one would have to be placed in 

 Doh'chosticha, Meyr., the other in Epiminia, Meyr., the types 

 of which two species are without the hair-covered fovea in 

 the cell. 



Type Lasiacme pilosa, sp. n. 



Lasiacme ptlosa, sp. n. 



Fore wings almost wholly suffused with dark fuscous 

 grey, the usual pale ground-colour only appearing beyond the 

 postmedian line; this runs obliquely parallel to hind margin 

 for two thirds, is very shortly curved in between first and 

 second median, then oblique again to inner margin at middle, 

 where it approximates to the end of the first line, which is 

 very obscure ; costa between the two lines with dark spots ; 

 tuft of fovea dark fuscous, the expansible tuft of hair white; 

 marginal area and fringes dark fuscous. Hind wings white, 

 with broad fuscous border, narrowing to a point at anal angle ; 

 a dark linear cell-spot ; the upper part of the postmedian line 

 forms a short streak from below the costa a short way in 

 front of the inner edge of the costal border ; the lower part 

 forms a continuation of the linear cell-spot to the anal angle ; 

 within this line the inner margin is slightly tinged with 

 fuscous ; the bed of hairs on the hind wings is narrow and 

 extends from apex nearly halfway to base. Underside 

 duller ; the foveal space, which is oblong and large, ochreous 

 white ; the down when expanded whitish. Frenulum long
