broadly dilated at tip, quadri-dentate outwardly, intermediate and 

 posterior ones with two and one spine respectively, and briefly 

 digitate at apex ; the basal abdominal segment is produced between 

 the hind coxas into a long cuneiform process slightly impressed trans- 

 versely and representing probably an absorbed sixth ventral segment ; 

 prosternal intercoxal process very declivous but sharp at tip. 



This genus seems to be found in South Africa only, and includes 

 one species, the two sexes of which seem, however, to have been 

 described as two different species.

Male : Black, opaque, glabrous ; head transverse, straight laterally 

 and also in the anterior part, where there is a median, moderately 

 sharp tubercle and another one on each side of it ; above the eye but 

 in a line with it, there is a slightly arcuate longitudinal ridge, the 

 intervening space is bi-impressed, and there is a transverse, basal, 

 shallow impression ; the surface has numerous deep but moderately 

 round punctures ; mandibles short, very robust, strongly bi-dentate 

 inwardly, convex and with a distinct prominence on the upper part ; 

 prothorax finely and closely punctulate, the punctures are deeper 

 and more numerous in the anterior part, the anterior outer angles 

 are rounded, the lateral part is ampliate and moderately rounded, 

 very obliquely attenuate towards the base with the outer basal 

 angles very sharp ; it is distinctly marginate all round, not very 

 convex, the base is only slightly emarginate in the centre, and there 

 is a slight, median, longitudinal furrow in the posterior part only; 

 scutellum not punctate at apex ; elytra not broader at the base than 

 the base of the prothorax, oblongo-ovate, a little longer than the 

 prothorax, convex, outer margins costate, almost reflexed for two- 

 thirds of the length, not striate, but having somewhat regular but 

 faint series of shallow punctures ; abdominal segments feebly punc- 

 tured except the apical one ; sternum and femora a little punctate ; 

 intercoxal prosternal process sharply aculeate ; anterior tibiae strongly 

 quadri-dentate, the two apical teeth broad, triangular, the two basal 

 ones a little smaller ; above the digitation there is a blunt, feebly
