ampliato-ovate, narrowly but deeply geminato-striate, and with the 

 intervals slightly raised and having each three series of deep, round 

 scrobiculate punctures, second interval not wider than the third, 

 humeral callus distinct ; pygidium finely shagreened and covered 

 with a dense greyish pubescence ; metasternum deeply punctured 

 in the centre and smooth only in the impressed line which is 

 distinct ; inner part of anterior tibiae non-spinose at the tip and 

 apical spur long, moderately slender and nearly straight in both 

 sexes. 



The presence of a slight frontal carina in the female is the only 

 outward character distinguishing it from the male. 



Length 5-6 mm. ; width 3-3i mm.

Onthophagus dispar, n. spec. 



Black, sub-opaque, very slightly pubescent ; head very rugose, 

 genae rounded, projecting a little laterally, clypeus semicircular, 

 sub-truncate at tip, and a little emarginate there, no trace of frontal 

 carina, in the median part of the vertex there is a high laminate 

 carina extending transversely over the greater part of the width, 

 truncate and aculeate at both ends and with the median part sub- 

 dentate ; antennae piceous red, club fusc6us ; prothorax ampliate 

 laterally, rounded at base where it is not distinctly marginate, 

 covered with deep, round, closely set punctures divided by narrow, 

 rugose walls, but granulose on the side, very briefly pubescent and 

 having a faint trace of an impressed longitudinal line in the posterior 

 part of the disk ; in the anterior part there are, in both sexes, two 

 median elongate tubercles often coalescing so as to make a short 

 transverse carina ; elytra distinctly ampliato-ovate, very narrowly 

 and deeply striate, intervals raised and filled with three series of 

 strongly scrobiculate briefly setigerous punctures which near the 

 base are scabrose, and are replaced by granules on the two first 

 intervals, second interval slightly wider than the third, humeral 

 callus moderately distinct ; pygidium deeply and closely pitted and 

 briefly pubescent ; metasternum deeply and closely punctured in the 

 middle, in the male there is a basal impression which is absent in 

 the female, and the median line is also more distinct ; inner part of 

 anterior tibiae slightly angular in the male but not spinose ; in this 

 sex the apical spur is thick and curved inward at tip, w^hereas in 

 the female it is slender and nearly straight.
