 thaji dorsum; clark- fuscous ; cilia oehreous. Hindwing-s rather short, ternien slight- 

 ly rounded; orange; basal half fuscous, the line of junction irregularly dentate; 

 cilia orange. Underside similar.

 / Palpi short, porreet; second joint sometimes hairy beneath; terminal joint 

 minute. Thorax and abdomen without crests; tuft large, especially in S. Pos- 

 terior tibiae with two pairs of spurs. Forewings without areole, 9 absent (coinci- 

 dent with 8), 7, 8, 10 stalked, 10 arising before 7, 6 approximated, connate, or 

 short-stalked. Hindwings with <lisc(icellulars angled, 3, 4, 5 separate, 6 and 7

The three genera Porthesia, Acijphas, and nahrophylla are doubtless deriva- 

 tives of Euproctis, wliicli they resemble in general appearance, but there are im- 

 portant structural differences. Acyphas is different from Euprnctk in the vena- 

 tion of both wings, and there is room for one or more intermediate genera . The 

 first species ascribed to this genus by Walker appears to be an Orgijia, but I 

 opine that the type was tixed by Kirby, and Swinhoe's name comes too late. 

 Although Acyphas is at present known only from Australia, it is not improbable 

 that it will be found to have a wider distribution, when the Indo-Malayan species 

 referred to Euproctis are critically examined.
