dilated at apex into a strongly triangularly divergent, bluntly 

 furcate, thick process, carinate across the diverging parts and 

 longitudinally along the basal part of the horn, which varies in 

 length from 1 to 3 mm. ; in the small development the short 

 anterior horn is very considerably reduced, being little more than 

 1 mm. in length, the head is excavated only as far back as the 

 eyes and deeply emarginate in the centre instead of being bi- 

 dentate ; in the 2 the head and clypeus are not excavate, the 

 latter is narrowed at the base and slightly rounded laterally, the 

 anterior margin is plainly sinuate in the centre ; prothorax of 

 the usual shape, but slightly more trapezoidal in the $ than in 

 the $ , arcuate on each side of the scutellum, and equally so above 

 it ; elytra elongated, attenuate towards the apex in the usual 

 manner ; anterior tibiae of $ dentate outwardly at apex only, and 

 simple inwardly, those of the ? sharply tri-dentate, sternal process 

 grooved from the base to a distinct suture separating the metasternal 

 from the mesosternal, the latter short, bluntly triangular with the 

 apical part slightly reflexed. 



The genus includes one species having many (so-called) varieties, 

 and which ranges west and east from Senegambia to Southern 

 Bhodesia.
