setose ; prothorax as broad as long, truncate at the apex, with the 

 anterior angles projecting, outer sides much recurved, very slightly 

 ampliated from apex to past the median part and slightly sinuate 

 above the base, thus imparting it a subquadrate shape, beset with 

 irregularly set, briefly setigerous punctures ; scutellum sharply 

 triangular ; elytra truncate at the base with the humeral angle not 

 very sloping, one-third broader than the prothorax, parallel for four- 

 fifths of the length, gradually rounded in the posterior part, hardly 

 convex for two-thirds of the length, the convexity more pronounced 

 towards the declivity, striate, with the intervals faintly convex in the 

 median discoidal part, nearly plane laterally, with the eighth interval 

 broader than the others, closely and regularly punctured, the punc- 

 tures briefly setigerous ; abdomen and tibiae pubescent ; legs dark 

 red with the intermediate and posterior tibiae and also the tarsi 

 darker, nearly black. Length 22 mm. ; width 8 mm. 



Hab. Zambezia (Salisbury). 



This insect, like Bhoioalomelus angusticollis, emits, when captured, 

 a fetid smell.

Mentum with a short median tooth triangular and bifid at tip ; 

 ligula triangular, broad at tip ; paraglossse disunited at a short 

 distance from the tip of the ligula and projecting much beyond it, 

 inner part of the lobes nearly straight, outer part rounded, tip very 

 sharp ; last joint of palpi fusiform, truncate at tip ; antennae not 

 very slender, the three basal joints glabrous, the others densely 

 pubescent ; mandibles long ; labrum a little broader than long, 

 truncate ; head slightly narrowed behind the eyes ; prothorax 

 broader in the anterior than in the posterior part and slightly sinuate 

 above the posterior angle ; elytra oblong, plane, narrowly striate, a 

 little sinuate behind ; legs moderately long ; tarsi triangular, not 

 grooved on the upper part, pubescent, those of the first pair a little 

 dilated and cordiform in the male, and with two series of lamelliform 

 scales under the three basal joints ; these scales do not extend 

 beyond the median part of the joints ; claws long, not pectinate. 



The genus is represented in South Africa by two species, one of 

 which may be said to be cosmopolitan.
