This species is readily distinguishable from all previously described 

 Australian Aulici by its colour and marking. It will be convenient 

 to compare it and others of its congeners with A. chry suras, 

 Chevr. (Thanasimus rufimanus, Gorh.), that being a previously 

 described species which there can be no difficulty in identifying 

 with certainty. Compared with it the present species inter alia 

 differs as follows : — Antennae much shorter (joints 9 and 10 much 

 more transverse, joint 11 much more emarginate at apex), pro- 

 thorax more transverse with much more strongly rounded sides, 

 fovese of the elytral series much larger (reaching the base and 

 extending much further towards the apex). Its nearest ally is 

 the species that I regard as A. episcopalis, Spin. (=instabilis,
