1897.] of the Goleoptera of South Africa. 97 



worthy of note that this variety does not occur with the type form, 

 which seems so far to be restricted to Stellenbosch, while the former 

 has only been met with at Muizenberg, where I found several females 

 and one male at the foot of grass ; but on the slopes of Table 

 Mountain I have met with some female examples in which the little 

 spine on the first dorsal segment has disappeared ; and this is to a 

 certain extent a transitory form between the type and the variety 

 bimucronata. 



Tkibe GONIACEEINI. 



Body variable in shape ; head elongate and provided with an 

 antennal tubercle, depressed laterally in front and more or less 

 dilated ; eyes placed forward ; antennae geniculate ; maxillary palpi 

 of moderate size ; abdomen marginate ; first ventral segment of 

 abdomen conspicuous, and projecting over the posterior coxae, 

 posterior and intermediate coxae apart from each other ; one tarsal 

 claw provided with a setiform appendage. 



In this tribe the antennae are geniculate as in the Curculionidce, 

 and not unlike therefore Metopius from America, but they are greatly 

 differentiated by other characteristics. 



The insects included in this tribe are not numerous, and seem to 

 be exceedingly rare ; they occur in America and Africa, but are 

 much more numerous in America, and four species included in two 

 genera were so far known from Abyssinia, Zanzibar, and the Gaboon ; 

 but my friend Mons. Eugene Simon, the well-known arachnologist, 

 who visited South Africa in 1892, has discovered a fifth one in the 

 Transvaal. These five species are known from single specimens only, 

 three of which I have myself captured in Abyssinia and Zanzibar 

 flying at sunset. 



Gen. OGMOCEBUS, Eaffr., 

 Eev. Entom., vol. hi., 1882, p. 7. 



Body oblong, somewhat depressed ; head provided with a frontal 

 tubercle, depressed laterally in front ; eyes set forward ; antennae 

 geniculate, elongate, eleven- jointed, club triarticulate ; maxillary 

 palpi moderate, triarticulate, first joint rather elongate, slightly 

 incurved, thickened at tip, second smaller, third briefly fusiform ; 

 abdomen broadly marginate ; legs somewhat elongate ; first joint 

 of antennae minute, second and third subcylindrical, third longer 

 than the others. 



Some species included in the genus (0. giganteus, agymsibanus) 

 are among the largest known Pselaphidce.
