There seem to be two species of the genus Creagris in 

 Queensland, C. lahrosus Niet., and C. icUsoni Cast. Follow- 

 ing Gestro, these can be separated as under : — 



Prothorax with basal angles obtuse G. lahrosus Niet. 



Prothorax with basal angles acute G. wilsoni Cast. 



Creagris labrosus Nieitner.

A single specimen, given to me by Mr. C. French as from 

 Mackay, is in my collection. I cannot differentiate it from a 

 specimen from Java, which is evidently C. labrosus. Length 

 9 mm.
