as distinctions from Sloanei except the form of the front margin 

 of the clypeus, and the structure of the transverse carina of the 

 pronotum, in which it resembles pugnax. The frontal carina 

 viewed from behind is an elevated line forming a regular strong 

 curve with its convexity forward, while in pugnax and Sloanei it 

 is sinuous with its median part widely and feebly curved in the 

 opposite direction. The clypeus is much shorter and wider than 

 in any other species known to me of this group. The distance 

 between the external tubercles of the pronotum is a little 

 greater than the width of the head.

 Very distinct from all the species of the laminatus group (with 

 which group it agrees superficially and in most characters) by its 

 conspicuously granulate and much narrower eyes. These re- 

 semble the eyes of 0. conspicuus, Macleay, which is a very much 

 more nitid and brilliantly metallic insect, with the pronotum in 

 both sexes much less closely and rugulosely punctured, and with 

 the punctures of the elytral interstices very much finer (indeed 

 almost wanting). The type is in the S. Australian Museum. It 

 is probably a female. Named after the late Dr. Bovill.
