Not unlike O. Adelaidae, Hope, but with the sexual characters 

 of quite different description, the elytra much less distinctly 

 striate with interstices flatter, and closely set with minute 

 setiferous granules, the eyes considerably wider, and on their 

 surface only very feebly facetted, etc. It must stand beside 

 O. Macleayi, Blackb., in my tabulation (T.R.S. S.A., 1903, 

 pp. 267, etc.), from which, however, it is extremely distinct by 

 many characters {e.g., the confluent asperate puncturation of its 

 pronotuin).

This species stands in my tabulation (T.R.S. S.A., 1903, pp. 

 267, etc.) besides henleyensis, Blackb., to which it is closely allied, 

 but the sexual characters ai'e extremely different. I know no 

 other Australian Onthophagus in which the frontal elevation in 

 the male at all resembles that of the present species, and the
