rufo-testaceous, with the basal margin nigrescent or fuscous, 

 antennae rufescent, club fuscous. Head hardly broader than long, 

 with sub-angulate gense, piceous tinted with coppery, sparingly 

 pubescent, minutely punctate in the centre and more deeply and 

 closely in front and on the genae, anterior margin of clypeus 

 moderately raised, sub-truncate or hardly distinctly sinuate in the 

 anterior part, vertex with an erect, subulate tooth dilated at base 

 and slightly shorter than the head in the $ , while the $ bears 

 there a transverse granule or a little distinct carinule ; prothorax 

 deeply emarginate at apex, obtusely and moderately rounded at the 

 base, convex on the upper part, somewhat distinctly retuse in front, 

 deeply and moderately closely punctate and with a rufous macule in 

 the middle of the sides ; elytra very finely striate, with the intervals 

 sparsely and most minutely granulate punctate, and with the punc- 

 tures very briefly setulose ; pygidium black like the under side, 

 sparsely punctate.

I mistook this species for Gaccobius viridicollis, Fahr. (Cat. i., 

 p. 173), which it greatly resembles, but from which it differs by the 

 armature of the head. d'Orbigny records it from Natal and the 

 Transvaal (Pietersburg). It was originally described from Abyssinia, 

 and has been found in British and German East Africa. 



Onthophagus declivicollis, d'Orbign., 

 Ann. Soc. Ent. Fr., lxxi., 1902, p. 72. 



" Somewhat shiny, black, head and prothorax blackish bronze, 

 elytra black piceous, briefly flavous pubescent on the upper side. 

 In the $ the head in front and on the vertex is nearly smooth, the 

 clypeus rugose, rounded at apex, the front has an arcuate carina, 

 and the vertex a narrow lamina briefly dentate on each side towards 

 the base, produced into a horn in the centre, and situated between 

 the eyes ; prothorax simply, strongly and moderately densely punc- 

 tate, the intervals between the punctures are nearly plane; in 

 the $ the anterior part is raised and produced in the middle, emar- 

 ginate and bi-tuberculate at apex, slightly hollowed near by and 

 smooth there, sides hardly sinuate behind, base marginate ; elytra 

 not deeply striate, intervals sub -convex and with an uneven surface, 

 moderately densely and irregularly granular, but the sides are 

 strongly and nearly simply punctate. Pygidium moderately deeply, 

 and moderately densely punctate.
