124 H - STEMPFFER 



Male genitalia (Text-fig. no). Uncus composed of two suboval lobes slightly angled apically 

 and separated by the deep depression of the posterior edge of the tegumen ; subunci curved, 

 very stout in the middle, the lower edge bearing short spines in its basal third ; tegumen large, 

 hood-shaped ; vinculum narrow dorsally and having a weak saccus ; lower fultura strongly 

 developed and with two wide flattened arms which are almost wholly fused together ; valves 

 composed of two lobes, the upper one oval, semi-membranous and, on this account, often 

 distorted when the genitalia are mounted for the microscope, the lower process shaped as an 

 elongate rectangle with the apex excised ; penis elongate, widely open dorsally, distally club- 

 shaped ; uncus and apices of valves pilose. 



The male genitalia of the other species of Hemiolaus are very similar to those of 

 caeculus. The shape of the subunci furnishes good specific characters.
