246 NOTES ON AUSTRALIAN COLEOPTERA, 



but more recently Dr. Kraatz and M. Thomson have not only 

 treated it as a distinct genus but have formed other genera at its 

 expense. Some of these latter are, I think, very unsatisfactorily 

 characterised, and founded on slight characters, even colour being 

 treated as generic. Strictly speaking, this present insect cannot 

 be referred to any of them, as its uniform metallic colouring 

 distinguishes it from all except Uemipharis itself, wliile its 

 scarcely emarginate clypeus and spinose posterior tibiae are incon- 

 sistent with a place in that genus as limited by the abovenamed 

 authors. I am unwilling, however, to propose a new genus, both 

 because subdivision appears to me already to have been carried 

 ratlKn- to an extreme in this group and because it is possible I 

 may have overlooked some generic name of non-Australian species. 

 As there is nothing except colour in this insect absolutely incon- 

 sistent with a place in DilocJirosis as briefly characterised by M. 

 Thomson, and as (apart from the form of the clypeus, which, 

 according to the diagnosis, is variable in that genus) it seems to 

 me nearly related to Schizorrhina atripennis, Macl., structurally, 

 which Dr. Kraatz says is a Dilochrosis, I am probably not far 

 wrong in adopting that name. The colour of this insect is a very 

 dark but extremely brilliant green, and I know no other Schizor- 

 rhinid bearing much resemblance to it. Its extremely short apical 

 ventral segment and pygidium strongly gibbous hindward indicate 

 its being a male.
