bristly ; lobes of ligula broad, joints of labial palpi moderately 

 long, apical one a little longer than the basal, sub-fusiform but 

 more swollen outwardly than inwardly ; head simple, with a dis- 

 tinct transverse clypeal and frontal carina ; prothorax diagonally 

 ampliate laterally from the anterior angle to a short distance from 

 the median part where it is a little rounded, and quite straight from 

 there to the basal angle which is moderately sharp ; scutellum short ; 

 elytra convex, nearly parallel, segments of abdomen apparently 

 connate, except the last one which is free ; metasternum grooved 

 but not impressed ; anterior tibiae strongly tri-dentate outwardly, 

 diagonal at tip, and not thickened inwardly, apical spur strong, 

 with the tip bent slightly inwards in the male, tarsi short, basal 

 joint of intermediate and posterior tibiae only half the length of the 

 longest apical spur. 



The characters distinguishing this genus from some species of Am- 

 moecius are, besides the abdominal segments which are not free 

 except the last one, the inwardly bent apical spur of the anterior 

 tibiae, and the ampliate ante-median part of the prothorax. 



The only two species known to me have the same habits as 

 AjjJiodius ; the sculpture of the elytra is very singular ; in one species 

 the line dividing transversely the punctures on the elytra has 

 become so raised that there are really twenty rows of punctures on 

 each side ; in the other it is only on the sides and in the posterior 

 part that this line is well defined. 



The genus, so far as is now known, is confined to South Africa.

Elytra with twenty punctured striae on each side cxmrita. 



Elytra with twelve strise on each side transitoria.

Black, shining, glabrous ; head closely punctate, clypeus broadly 

 emarginate, genae in a line with the clypeus but projecting much at 

 right angle with the eye, there is a distinct, transverse, clypeal 

 carina and another one not quite so well defined between the eyes ; 

 prothorax diagonally ampliated laterally from the outer angle to a 

 short distance from the median part where it is a little rounded, and 

 nearly straight from there to the posterior angle which is moderately 

 sharp, it is somewhat convex, marginate along the base which is
