upper^ in the same straight line^ slightly concave ; discoidal nervule 

 well developed ; second median nervule arising immediately before the 

 lower end of the cell ; first median arising about four times as far from 

 the base of the second as the second does from the third ; suhmedian 

 and internal nervures sinuous. Antennce exactly half the length of the 

 costa of the forewing, with a well-formed curved club. Palpi with 

 the third joint minute, pointed ; second and first densely pilose, broad. 

 Thorax rather robust. Hind legs with a dense bunch of hairs spring- 

 ing from the base of the tibia and lying along that joint, which they 

 equal in length. Abdomen short, robust, not nearly reaching to the 

 anal angle of the hindwing. Female. Differs from the male only in 

 the hindwing being considerably broader, and in lacking all the male 

 secondary sexual characters. 



In neuration Crossium appears to agree very closely with Capita and 

 Pisola* Moore, but may be distinguished by the outline of the wings. 

 In the forewing the male of Crossiura has the apex less sharply pointed 

 than in Capita, more so than in Pisola ; and the inner margin is longer 

 than in Capila, shorter than in Pisota. The shape of the hindwino- 

 is quite different, being greatly lengthened, and the dilatation and 

 folding-over of the wing-membrane of the anal angle, which is there 

 furnished with long stout setae, is an altogether unique feature in 

 the family as far as I know, though, perhaps, Mr. Butler's genus 

 Spathilepiaf which, according to Mr. Kirby's Catalogue of 

 the Butterflies, contains seven species all inhabiting South America, 

 may have a somewhat analagous structure, the anal angle of the 

 hindwing being " clothed with long radiating spatulate scales in 

 place of ordinary fringe."

Habitat : Khasi Hills. 



Expanse : S, 2*5 to 27 ; $ , 2-65 to 275 inches. 



*The neuration of the genus Pisola is apparently very erratic. In one out of five 

 specimens of the male from Sikkim in my collection the fourth subcostal nervule 

 of the forewing is emitted after the apex of the discoidal cell — a quite abnormal 

 feature in the Heiperiidoe ; and in one out of three female specimens from Sikkim 

 the neuration of the hindwing is ao abnormal that I have given a sketch of it on 

 PI. J, Fig. 3.
