Onthophagus trinodosus, Falir., 

 Insect. Caffrar., ii., p. 280. 



Quite similar in shape to O.parumnotatus, and .might at first sight 

 be taken for a variety of it in which the prothorax is light bronze 

 and tlie testaceous spots have invaded the whole of the elyti'a 

 leaving only from seven to eight fuscous round spots as a remaindei' 

 of the original colour, but the granules on the prothorax are finer, 

 and are set so closely as to be almost contiguous, and the intervals 

 on the elytra are filled with more numerous and therefore more 

 closely set setigerous punctures ; the pygidium is also more closely 

 punctulate ; the number of fuscous round spots on the elytra varies 

 from six to eight. In his original description Fahroeus rightly 

 mentions seven spots only on the elytra ; in the only example at my 

 disposal, a male, there are eight distinct ones.

Testaceous or pale-chesnut and with a lesser or deeper bronze 

 tinge on the head and the median part of prothorax ; head granulato- 

 punctate, clypeus rounded, but slightly blunt at tip, frontal carina 

 very distinct, antennae flavous ; prothorax not very convex, am- 

 pliated laterally, rounded in the middle at base, truncate vertically 

 in the anterior part which is not excavate but is perpendicular and 

 has the upper edge of the truncate part produced into four sharp 

 recurved tubercles, the two median ones of which are a little longer 

 than the two sub-lateral ones," it is covered with closely set punc- 

 tures, but the sides are scabroso-punctate, and there is a smooth 

 not very distinct longitudinal line in the middle ; elytra elongate, 



* In tlic figure the prothoracic tubeLCules arc not sufficiently in line.
