If the expression "subtruncata et biacuta" applied to the 

 apex of the elytra of this species means that each elytron has 

 two apical mucros, I do not know it; but a species that may 

 be beaten from many kinds of Casuarina in Queensland 

 (Dalby, Bluff, and Cairns), New South Wales (Sydney, Mitta- 

 gong, and Whit ton), Tasmania (Launceston, Hobart, Beacons- 

 field, and Swansea), and South Australia (Parachilna and 

 Ooldea) seems to me (apart from the quoted expression) to 

 agree with the description. The specimens of it have the sides 

 of the elytra obliquely narrowed to the tips (on some 

 appearing obliquely truncate) with each tip acute at the 

 suture (this is especially noticeable when the elytra are 

 separated). On some specimens the sides of the prothorax are 

 more strongly rounded than on others (possibly a sexual 

 difference) and Tasmanian ones are somewhat larger than 

 those from the mainland (a common variation). They all 

 have a metallic gloss, but this is but little in evidence on some 

 specimens. The species is certaintly not casuarinae, from 

 some co-types of which it differs in being much smaller and 

 less coarsely sculptured, with the elytra rather more acutely 

 pointed (although the difference in the tips is not very 

 striking).
