Adelidea braunsi, n. sp. 



A small species, at once distinguished by the equally infuscated, 

 not spotted wings, which have, moreover, a short discoidal cell. 



Two 9 specimens from Willowmore (Cape), April, 1920 (collected 

 by Dr. H. Brauns, in whose honour the species is named). 



The present species cannot be the A. fasclpennis of Macquart as 

 one may conclude from the name, the wings being described as 

 yellowish at base and dark spotted.

 style. Face rounded, convex, blackish brown, with short blackish 

 hairs at sides and at mouth liorder. Palpi black, long ; proboscis
