of tibiae with a short straight spur, outer angle of anterior pair with 

 a truncate process ; tarsi moderately long and stout. 



Cape Colony (Drege). 



Type in the Stockholm Museum. 



Its more elongate shape and the greater width of the thorax as 

 compared with the elytra give this insect a very distinctive facies ; 

 the conical tubercles at the base of the elytra are also peculiar to it. 

 I have seen only the type specimen.

Long. 7f ; lat. 4J mm. 



Colour uniform earthy-brown, the apices of the tubercles on the 

 elytra bare and black ; with short thick black suberect setae. 



Head with a low obtuse central carina. Prothorax dorsally 

 broader than long, the sides strongly rounded, broadest behind 

 middle, constricted near apex and narrowed behind, the base 

 subtruncate ; upper surface with the punctures hidden by the 

 dense scaling, the posterior portion very convex and with two small 

 depressed tubercles in the middle, very steeply declivous in front, 

 the transverse subapical impression shallow and without fovese. 

 Elytra oblongo-ovate, the basal margin slightly sinuate and not 

 broader than the base of the prothorax, shoulders rounded, sides 

 subparallel thence to beyond middle, the declivity steep but rounded 

 dorsally ; upper surface convex, with irregular rows of large sub-

South Africa [Sir Andrew Smith). 



Type in the British Museum. 



Nearly allied to hinodosus, Mshl., from which it differs in its 

 strongly declivous and more rounded thorax, its rounded shoulders, 

 the thick setae and the absence of the prominent basal tubercles on 

 the elytra.
