tri-dentate at apex, and with the apical part either straight in a Hne 

 with the base of the outer apical tooth, or truncate below its base, 

 anterior tarsi slender, apical spur strong, thick and curved inwardly 

 nearly at right angles at tip ; intermediate and posterior tibiae broadly 

 dilated and compressed at apex, shallowly grooved on the upper side 

 and with the edges of the groove closely serrulate ; tarsi short, 

 triangular, except the fifth which is elongate and a little longer than 

 the other four, which gradually decrease in size ; the basal one is 

 very broad in several species but not as long as the two following 

 put together. The two sexes are alike. The last sternite or cylin- 

 drical joint of the genital armature of the male is as long, or slightly 

 longer than the valve, the shape of which, although variable in 

 thickness proportionally to the size, remains nearly the same 

 (pi. xxxviii., figs. 31-32). 



The lateral emargination of the elytra is strong in six species 

 only ; it is less marked in C. harratti, and in C. nana, armata, and 

 imitativa it is absent, but in these last three species there is a 

 supra- marginal, longitudinal carina beginning where the emargina- 

 tion occurs in the first-named species, and reaching almost to 

 the rounding of the posterior part ; these three species have also 

 tuberculate elytra. 



Found either in fungi or sometimes in dung, and the cocoon 

 of the larva is like that of a Copns, according to Mr. R. M. Light- 

 foot. 



The genus is represented on the West Coast of Africa (Guinea) 

 and in Eastern Africa (Usagara). One species from Northern India, 

 the clypeus of which is quadri-dentate, has also been described, but 

 it probably belongs to the genus Delopleunos. 



Key to the Species. 



A=. Elytra very deeply sinuate laterally. 

 B^. Prothorax excavate or retuse in front. 



C3. Striae of elytra slightly punctate, intervals plane. 

 D3. Head with a frontal carina. 



Head with a transverse frontal line ; prothorax sloping 

 for two-thirds of the length, carinate and with the 

 carina moderately deeply emarginate in the centre 

 with the angles of the emargination not dentate — 



Head with a transverse interrupted frontal line . . klugi. 



Head with a non-interrupted frontal line vicina. 



Head with the frontal raised line in the shape of a 

 triangle ; prothorax sloping for half the length and 

 strongly bi-tubercul ate at the top auspicata.
