the transverse row ; metasternum, hardly impressed longitudinally ; 

 basal intercoxal process of prosternum strongly sloping, triangular, 

 carinate all round and grooved transversely along the lower part. 



Length 23-27 mm. ; width 11-13 mm. 



Boheman evidently saw female examples only, judging from his 

 description, and from his type. The males seem to be much rarer, 

 and I have seen only two examples. There is little doubt that 

 Bhizoplatis amhignns, Gerst., is identical with Boheman's B. castanci- 

 jpennis. 



Hab. Transvaal (Johannesburg, Potchefstroom, Klerksdorp, 

 Lydenburg). I believe, but am not quite sure, that my male 

 example from Johannesburg was found in a Termite nest. 



Sub-Family EUTELIN^. 



Ligula horny and fused with the mentum, slightly or strongly sloping 

 backwards ; labial palpi inserted laterally ; maxillas always robust, or 

 very robust, inner lobe obliterated, but showing faintly in Isoplia, 

 upper lobe provided with strong, more or less falcate teeth, with the 

 exception of Gnatholabis, mandibles plane, and densely ciliate 

 inwardly, sub-triquetrous, or very convex and triquetrous, and 

 fringed on the base only with short dense ciliae {Adorctus, &c.), 

 projecting slightly or distinctly beyond the labrum which is free, 

 horizontal, sub-horizontal or quite vertical ; clypeus simple, not in- 

 cised ; genae reduced to a mere canthus ; eyes large ; antennae eight- to 

 ten-jointed, club tri-jointed not much developed in the African insects, 

 even in the male ; sci;tellum of moderate size in the South African 

 genera, with the exception of PhcEuoincris where it is very elongated ; 

 elytra covering the basal part of the propygidium and having or 

 not an epipleural membrane ; anterior coxae transverse, except in 

 Phcenovieris , and Isoplia ; mesosternum produced sometimes in a 

 projecting aculeate or carinate process, mesothoracic epimera more 

 or less projecting ; legs mostly robust, hind and intermediate tibiae 

 with two or more oblique rows of short bristles on the outer part, 

 and having two apical spurs ; claws of anterior and intermediate 

 tarsi unequal, sub-parallel or very little diverging, the more robust 

 claw mobile, a seta between the two claws ; last three spiracles of 

 the abdomen placed on the ventral segment. 



Owing to the presence of unequal claws, the stronger of which is 

 hinged, this Sub-Family is connected with the HopliincB, but is at 

 once distinguished by the presence of two apical spurs on the inter-
