This very small Onthophagus was given to me by Mr. Lea. 

 From its immediate allies it differs as follows, inter alia : — From 

 JDumbrelli, Blackb., by the dark club of its antennae ; from 

 sydneyensis, Blackb., and Fletcheri, Blackb., by the close strong 

 puncturation of its elytral interstices. It aho resembles some 

 species of Group V". If its pronotum were margined at the base 

 it would fall in the tabulation beside O. henleyensis, Blackb., 

 a,nd jubatus, Har., differing from both (female) by the very much 

 finer puncturation of its pronotum. It has much superficial 

 resemblance to the female of 0, nitidior, Blackb., from which 

 (disregarding the unmargined base of its pronotum) it differs by 

 the strongly sinuous and scarcely distinct carina of its pronotum 

 as well as by the much more close and confused puncturation of 

 its elytral interstices, (fee. The irregular puncturation and the 

 uneven coriaceousness of its elytra give the interstices a some- 

 what rugulose appearance, — the more nitid part seeming to be 

 unevenly prominent.
