152 Annals of the South African Museum. 



Abdomen smooth, shining ; the apex of the apical segment is 

 narrowly white. 



The apex of the fore femora and the tibiae are testaceous in front. 



The ^ has the wings fuscous violaceous except for a hyaline 

 cloud extending from the commencement of the radius to the base 

 of its apical third ; the antennae want the white ring ; the sides of 

 the face have the red colour tinged with yellow, the red on the base 

 of the mandibles being also tinged with yellow ; in it also the apex 

 of the petiole has a violaceous tinge and the abdomen is more 

 densely pilose ; the second segment is narrow at the base ; it 

 becomes gradually wider towards the apex. The apex of the 

 clypeus is more transverse than it is in the J . The palpi in both 

 sexes are black ; the mandibles broadly rufous at the base. 



The S I have described may belong to another species, as, e.rj., 

 the fore wings are not hyaline at the base and the hinder pair are 

 entirely smoky. The material at my command does not warrant me 

 in describing the $ as a distinct species. Cryptus inctipennis, 

 Tosq., from Cafifraria (only the J is known), is clearly another 

 species of Cryptaulax. No mention is made of a tubercle or small 

 tooth or projection on the apex of the clypeus, which is. described as 

 having the " margine anteriore rotundata " ; and the posterior lobes 

 of the " prothorax " are said to be transversely striated ; and the 

 pleurae " are more finely punctured " than the mesonotum ; in the 

 S I have described they are not punctured, but coarsely reticulated, 

 although not quite so strongly as in the $ . The transverse median 

 nervui'e, however, is said to be interstitial ; but the mesonotum is 

 said to be " sans aucune division," and the transverse median ner- 

 vure is broken above the middle. As the areolet is described as 

 " small " it can hardly be a true Cryptus. It is further to be noted 

 that the abdomen is said to be " smooth," which is certainly not the 

 case with either the J or $ I have described. 



Ceyptaulax erythkostomus, sp. nov. 



Black, the clypeus and mandibles, except at the apex, red ; wings 

 hyaline ; a cloud commencing on the inner side of the transverse 

 basal and transverse median nervures, extending to the base of the 

 stigma and the middle of the disco-cubital nervure, the cloud being 

 therefore much narrowed in front, and the apex from shortly behind 

 the base of the apical third of the radius, fuscous violaceous ; the hind 

 wings are entirely hyaline ; the nervures and stigma black. 3 . 



Length 12-13 mm.
