emarginate on each side, frontal part not carinate, vertex tuber- 

 culated between the eyes; prothorax closely asperate punctate, 

 granulate in the anterior declivity and towards the sides which are 

 strongly sinuate behind ; the base, which is angularly produced 

 behind, is entirely marginate ; elytra finely striate, intervals almost 

 plane, moderately densely and strongly rugose punctate ; pygidium 

 sub-densely asperate punctate.

Described from one example, probably a 3 . 



Hab. Southern Ehodesia (Victoria Falls)." 



Onthophagus (Proagoderus) quadrituber, n. sp. 



Head and prothorax metallic green, posterior part of the prothorax 

 usually tinted with obscure blue in the centre; elytra testaceous 

 with a brownish tinge and with the juxtasutural stria metallic 

 green ; pygidium light greenish bronze. Epistoma rounded, frontal 

 part without ridge or with a very short one (<?), with a very 

 angularly arcuate ridge ( ? ) ; vertex with a horn that is usually 

 very long, regularly arcuate, strongly gibbose beneath a little before 

 the middle ( $ ) ; vertex with a carina, straight or sometimes slightly 

 arcuate backwards in its median part ( ? ). Prothorax more or less 

 broadly smooth in the centre along the whole or nearly the whole of 

 the length ( $ ) ; on about two-thirds of the length behind ( ? ) ; the 

 punctuation of the remainder of the surface is large, asperous except 

 on the sides (<?), and moderately granular, the anterior part and a 

 broad space on the sides ( $ ) granular ; the anterior part in the $ 

 bears two large teeth situated nearly behind the anterior angles ; the 

 discoidal part has two large dentiform tubercles situated at about 

 the anterior third part of the length and divided by a moderately 

 large depression turning behind into a longitudinal furrow reaching 

 the base ; in addition there is on each side a somewhat strong 

 depression between the tubercle and the tooth; in the ? the 

 anterior part has a strong median projection ogival at tip, and on 

 each side a moderately large tubercle ; the sides are strongly sinuate 

 near the posterior angles, the base has a very narrow fold on the 

 sides, and expands broadly into a lamina in the centre. Intervals 

 of elytra plane, the punctuation simple, close and moderately strong. 

 Length 10-13 mm.
