222 H. STEMPFFER 



third segment slender, acuminate, clothed with white scales on the inside and black scales on 

 the outside ; antennae slender, about three-fifths the length of the costa, club oval, flattened, 

 well differentiated ; thorax fairly robust, clothed below with long silky hair ; q* fore leg, femur 

 clothed with long grey hair, tibia slightly shorter than the femur, tarsus unsegmented, finely 

 spinose below. 



Wing shape. Fore wing subtriangular, apex angular margin convex, hind wing oval, no tail, 

 anal angle rounded. 



Wing venation (Text-fig. 330). Fore wing with 11 veins. 



Male genitalia (Text-fig. 193). Uncus composed of two oval lobes fused to the posterior edge 

 of the tegumen, each lobe bearing near its apex a small prominent tubercle crowned with long 

 strong stiff bristles (N.B. as this tubercle is rather soft, it is easily displaced when the genitalia 

 are mounted ; sometimes it is pushed sideways as in the case in the figure, sometimes it is 

 pushed upwards, projecting above the posterior margin of the tegumen so that it is difficult to 

 prepare mounts that are strictly comparable in respect of all details) ; subunci long, slender, 

 curving, tapering gradually from the base to the pointed apex which bears a wide-open claw ; 

 tegumen very large, prolonged towards the eighth abdominal segment by a wide rounded 

 expansion ; vinculum narrow, almost at right-angles to the tegumen when seen in side view, 

 lower fultura composed of two long curved arms fused together at their bases and arising from 

 the origin of the valves ; valves oblong, their general shape reminding one of a human leg 

 including calf, ankle and foot, the internal surface bearing near its base a small protuberance 

 which possibly corresponds to a connection between the valves and the tergal elements of the 

 genitalia ; penis short, massive, vesica with numerous cornuti ; uncus densely clothed with 

 long fine hair, distal portion of the valves sparsely clothed with short hairs. 



The male genitalia of all the species or subspecies of Harpendyreus examined are 

 of the same type as those of H. reginaldi except those of H. notobia (see below). 

 Their specific characters are found mainly in the shape of the valves, but these
