This has been called the same as the Furopean dispar Ijinnanis," but 

 the moths are twice the size and the female more dusky colored. I 

 should call it a good geographical race at least. Swinhoe lists it as a 

 distinct species.* The egg mass, larva, and pupa are preserved, all as 

 in dispar, but proportionateh' larger. 



EUPROCTIS CONSPERSA Butler.

Food plant: Thea cJiinensls. 



The larva? are apparently gregarious. Head rounded, 

 pale reddish, inmiaculate. Bod}^ cylindrical, robust, ta- 

 pering a little on the thorax. Tubercles small, flattened, 

 with weak, but numerous, hairs, longer subventrally. 

 On joints 5 to 12 a circular subdorsal area involving warts 

 i and ii is slightly raised and tufted with hairs. The areas 

 become continent on joints 5 and 6, but are smaller and separate pos- 

 teriorly. Dorsal eversible glands of joints 10 and 11 weak, and not 

 contrastingly colored. Dorsum reddish; a ])road l)lack subdorsal band 

 separated by a narrow yellowish line from a black lateral one aliout 

 half the width of the subdorsal. , Sides and subventer pale. Subdorsal 

 areas black, weakly tufted with short hairs, which do not 

 form tussocks. Subdorsal wart of joint 2 suljpapillose.

Food plant: Morxis alba. 



The larva differs strikingly in coloration from its Eu- 

 ropean representative, though it has the same structure 

 and pattern. The subdorsal tubercles of joint 2, sub- 

 ventral ones (tubercle v), and a patch on joint 13 are 

 bright red, but the other markings are yellow. Instead 

 of the double narrow red dorsal line of the European larva there is a 

 broad yellow band covering the whole dorsum to tubercle ii, single, or 

 divided by a reddish dorsal line. The semicircle about the tuft on
