Only the above species has been described as belonging to 

 this genus, which is easily distinguished from the other Ateuchidte 

 and Copriidse by its hemispherical shape and its obtusely rounded 

 clypeus. The var. lyceus was applied by Westwood to the large 

 shining examples of hacchus, but as this is no distinguishing feature 

 the name will probably have to become a synonym. 



I have just had the opportunity of examining a series of 

 insects captured in Matabili-land during the recent outbreak, 

 and was struck with a few extremely diminutive forms of hacchus; 

 and, as all of them are without exception under 16 lines, I take 

 the opportunity of describing it as follows : — 



hacchus var. ivaterhousei. — Size smaller, punctures on disc of 

 thorax thick, coarser round base and margins, the posterior 

 margin strongly sinuate. The striae on the elytra deeper, and 

 the basal portion of the elytra not crenulate as in hacchus, of a 

 dull black colour, the hind tibiae being furnished with a number 

 of short spines very close together, and more numerous than in 

 hacchus; the spines or teeth in one or two examples are obsolete, 

 being evidently worn away by friction ; the carinae on the meta- 

 sternum scarcely visible and almost obsolete ; metasternum im- 

 punctate. L. c. 15 lines (16 = 1 in.). Hab. Matabili-land.
