4. Protoparce perplexa sp. nov. 



cJ. In colour and markings almost exactly like P. pelleiiia H.-S. (1854). 

 Head and palpi a little more extended black; nuderside of abdomen less shaded 



with fuscous, the base being white. Forewing broader and along the costal 



margin darker than in F. pellenia, the black sericeous patch situated below R' 

 longer, the sericeous area conseijuently more incurved between R' and costal 



margin. The light discal band of the hindwing much shaded with black ; the 



black submarginal band narrower than in P. pellenia. 



On iindi'fside the discal lines of forewing fainter even than in P. pellenia. 

 Hindwing darker, only the abdominal area being greyish white ; the black-brown 

 discal dentate line single, there being just a vestige of the proximal line found 

 on the disc in P. pellenia. 



Harpe very much broader than in P. pellenia, widest at apex, which is 

 rounded and curved inward. The other parts of the genitalia as in P. pellenia. 



1 c?. The conspicuous difference in the harpe induces us to treat the specimen 

 as representing a distinct species.
