Genus POWELL AN A Bethune Baker 



Powellana Bethune Baker, 1908, Proc. zool. Soc. Lond. 1908 : 114 ; Aurivillius, 1920 : 360. 

 Type-species : Powellana cottoni Bethune Baker, by original designation. 



Eyes naked ; palpi protruding far beyond the frons, second segment slightly swollen, clothed 

 with adpressed scales, third segment fairly long, acuminate ; antennae slender, with a poorly 

 differentiated, gradually swollen, fusiform club ; $ fore leg with long slender tibia, short un- 

 segmented tarsus, bearing fine spines below. 



Wing venation (Text-fig. 272). Vein 11 branches from 10 near its base, a rare condition 

 which occurs also in Neoepitola. 



Male genitalia (Text-fig. 89). Uncus crescentic, the hind edge evenly rounded ; subunci 

 long, slender, curving, swollen in the distal half, then tapering ; tegumen triangular ; vinculum 

 narrow, prolonged to form a long saccus ; lower fultura fused to a fold of the base of the valves, 

 closely sheathing the base of the penis ; valves oblong, ending in a small rounded process ; 

 penis robust, elongate, slightly curved, the apex obliquely cut and widely open ; uncus and 

 distal edge of valves densely pilose. 



The genitalia of P. cottoni closely resemble those of most of the species of Epitola.
