386 Mr. A. G. Butler on Madagascar Lepidoptera. 



with strongly convex costal margin (so that when at rest it 

 appears in front of the primaries as in Gastropacha) , densely 

 fringed with hair ; costal vein bifurcate from base, the supe- 

 rior furca terminating at the middle of the margin, and the 

 inferior one a little before apex ; subcostal simple, emitted 

 close to the costal vein, which it almost touches just beyond 

 the furcation ; no discocelluhtr ; median vein four-branched. 

 Type L. anomala. 



40. Lechriolejns anomala , sp. n. 



Ochreous : primaries traversed by three tawny stripes, the 

 first of which is slightly irregular and crosses the wing at basal 

 fourth, the second zigzag and central, the third discal, macular, 

 and zigzag ; a large ferruginous spot in the cell : secondaries 

 pale towards the base ; a central costal brownish dash : abdo- 

 men pale, with testaceous anal tuft, having dull golden reflec- 

 tions in fresh females, in which it has not been disturbed for 

 the purpose of oviposition. Under surface uniformly ochraceous, 

 excepting the anal tuft ; costal area of primaries on each side 

 of the singularly modified subcostal streak clothed with long 

 appressed hairs mixed with ordinary scales. Expanse of 

 wings 2 inches 4 lines. 



Evidently not a rare species. 



This genus is aberrant in almost every character, its 

 neuration being, in fact, unlike that of any characterized genus 

 of moths ; the arrangement of the scales upon the partially 

 bare patch on the primaries is, moreover, so abnormal that, 

 but for the large anal tuft which the female evidently cuts off", 

 like the genera Euproctis and Porthesia, to cover its eggs with, 

 I should feel obliged to found a new family for its reception. 

 As it is, I am satisfied that this and two other genera which I 

 must characterize here are sufficiently aberrant to be regarded 

 as a distinct subfamily, for which I therefore propose the name 

 of Lechriolepidinw. 



The two following genera were received in previous collec- 

 tions ; but, from their similarity to known genera, their struc- 

 tural differences were unfortunately overlooked. 



Rahiipeza, gen. nov. 



Allied to Lechrtolepis, but with the aspect of Gogane ; in 

 neuration it differs from Lechrtolepis as follows : — primaries 

 with the lower radial emitted from the superior angle of the 

 cell instead of as a fourth median branch ; discocellular trans- 

 verse and slightly angulated ; costal vein of secondaries with 

 its superior furca extremely short, so as to answer the purpose 

 of a precostal veinlet, subcostal with two branches. In other
