CRYPTOBLABESl PHYCITIDAE 



horny apical hook. Labial palpi rather long, curved, ascending, 

 with oppressed scales, terminal joint moderately long, pointed. 

 Maxillary palpi short, loosely scaled. Forcwings : 4 and 5 

 approximated. Hindwings : cell hardly reaching £, 4 and 5 

 approximated, 7 anastomosing with 8 to middle. 



Includes only the single species. Imago with forcwings 

 narrow, costa slightly arched.
