Plate XXXV., figs. 14, 14a. 



Trans. S. Afric. Phil. Soc, vol. iv., 1888, p. 97. 



Fuscous bronze, with a little brighter sheen on the head and 

 prothorax, briefly pubescent, antennae flavous ; head closely punc- 

 tulate on the clypeus, vertex nearly impunctate, genge sub-angular 

 at about the median part, clypeus aculeate, obtuse at tip, and 

 recurved there but not strongl}^ frontal carina and suture of genae 

 distinct ; prothorax ampliate laterally, distinctly marginate all 

 round, rounded at base, retuse in front in both sexes, although 

 less so in the female than in the male, and more or less strongly 

 bi-tuberculate in the centre of the anterior part, it is very closely 

 scabrose and briefly but deeply pubescent ; elytra ampliate, narrowly 

 and shallowly geminate and punctato-striate, intervals plane and 

 filled with closely set minute briefly setigerous granules, second 

 interval not wider than the third, humeral callus distinct ; pygidium 

 very closely scabroso-punctate, briefly pubescent ; metasternum 

 closely punctate, median longitudinal line distinct ; inner part of 

 anterior tibiae non-spinose, apical spur moderately slender, nearly 

 straight in the male, but a little curved in the female. 



Male : Basal part of vertex produced in a laminate horn broad 

 at base, gradually attenuate as far as the median part, cylindrical 

 from there and curving forward, this horn may be higher than 

 the apex of the anterior part of the prothorax, or reduced to a 

 triangular carina, the two tubercles in the anterior part of the 

 prothorax, which is abruptly declivous, are not close to one another 

 and are more or less sharply conical. 



Female : Vertex wath a basal transverse high carina, slightly 

 aculeate at both ends and also in the centre ; anterior part of 

 prothorax less retuse than in the male, but with two small tubercles 

 set nearer to one another. 



Length 8-10 mm. ; width 5-6 mm. 



Hah. Natal (Durban, Malvern, mouth of the Umkomas Biver), 

 Cape Colony (Griqualand West), Southern Ehodesia (Victoria Falls, 

 Salisbury). 



Onthophagus ^equatus, n. spec. 



A close ally of the preceding species, but the colour is brighter 

 bronze, and the elytra have a humeral and an apical testaceous 

 red patch on each side, the intervals of elytra, which are also 

 geminato-striate with the striae closely punctured, have only two 

 series of not closely set setigerous punctures, and in the male
