completed as follows : Clypeus arcuately rounded and with the 

 anterior margin entire, head somewhat roughly punctured on 

 the clypeus, sides and vertex, but with the median frontal part 

 finely punctate and bulging without being tuberculate ; near the 

 vertex and above the eyes is a short, median, transverse ridge, and 

 the whole head is densely pubescent, the pubescence is short, erect, 

 and sub-flavescent ; prothorax simple, with the base weakly margi- 

 nate, covered with equi-distant, simple punctures all setigerous and 

 separated by an interval equal to their own diameter ; pygidium 

 covered with fine umbilicate punctures. 



M. H. d'Orbigny separates G. inconspicuus, Fahr., from C. fuligi- 

 nosus, Both., from Abyssinia, with which it was united by Harold. 

 As it is now included in the genus Caccobins, Fahraeus' specific name 

 is no longer in synonymy, and must be retained.

This species differs from C, inconspicuus in bearing a slightly 

 more sparse pubescence ; the prothorax has deeper and broader 

 punctures, some of them somewhat umbilicate ; in the anterior part 

 there is a minute longitudinal carina wanting in C. inconspicuus ; 

 the head is more scrobiculate in the centre, the frontal carina is 

 similar, but there is no trace of a ridge on the vertex, and the 

 pygidium bears larger umbilicate punctures.

Caccobius obtusus, Fahr., $ , Catal. i., p. 221. 

 C. mastrucatus, Per., $ , Cat. i., p. 191. 



M. H. d'Orbigny, to whom I sent, at his request, my examples 

 of the two sexes of this species, pronounce the 2 to be that of 

 C. fuliginosus, although the two were taken together. The £ is less 

 densely pubescent both on the prothorax and on the elytra, and the 

 punctures on the former part are broader, deeper, and umbilicate. 

 Moreover, the minor development of the $ has, like the ? , a minute 

 longitudinal carina on the prothorax. 



Caccobius viridicollis, Fahr., Cat. i., p. 193. 



According to d'Orbigny (Ann. Soc. Ent. Fr., 1902, p. 9), I have 

 mistaken two species under that name, i.e., 0. brevicollis, Fahr., and
