H. STEMPFFER 



Eyes large, smooth ; palpi fairly long, ascending and projecting well beyond the frons, second 

 segment clothed with long, erect hair, third segment short ; antennae long, slender, white-banded, 

 club well differentiated, clavate ; thorax moderately stout, abdomen long and reaching beyond 

 anal angle in the male ; q* fore leg with tibia not swollen, tarsus unsegmented, finely spinose 

 below. 



Wing venation (Text-fig. 239). In the o* of eleaza on the fore wings vein 10 arises from the 

 upper angle of the cell ; in the $ it branches from the common stem of vein 6 and 7 + 8 + 9 ; 

 in isca vein 10 arises from the anterior margin of the cell. On the hind wing vein 5 is nearer to 

 6 + 7 than to 4 in all species. 



Male genitalia (Text-fig. 24). Uncus deeply divided, formed of two long symmetrical leaf- 

 like expansions with pointed apices. Subunci absent. Tegumen reduced to a narrow strip. 

 Vinculum narrow with an indistinct saccus. Lower fultura fused to the base of the valves and 

 sheathing the internal part of the penis. Valves oblong, slightly falcate at the apex. Penis 

 small, proximally widely open dorsally, the distal (outer) part strongly recurved. Uncus 

 delicately pubescent, distal half of valves thickly hairy. 



All the male genitalia of Psenderesia that I have examined bear a definite resem- 

 blance to those of P. eleaza : the uncus is always bifid, though less deeply divided, 

 the subunci are absent, the valves oblong. The penis of P. paradoxa shows a certain 

 resemblance to that of eleaza, but those of isca (Text-fig. 25), ouesso, nigeriana, 

 phaeochiton, osheba, clenchi, rougeoti, bent and rutilo, differ in that the distal portion 

 of the penis is not recurved. The penis of bicolor (Text-fig. 26) is of a very different 

 type, the outer portion very long, cylindrical, bent at an obtuse angle and open 

 dorsally to allow the passage of the vesica, which bears numerous cornuti.
