obsolete at apex. Abdomen faintly striate, intercoxal process wide 
and round, presternum convex, its processi wide, produced, rounded, 
and slightly reflexed at apex. Tooth of submentum produced only 
horizontally forward ; hind tibia? with thin line of tomentum.

Habitat: Nunga, Queensland (A. Bishop). 
A single specimen, sex doubtful, labelled as above, is amongst 
some TenebrionidaB sent by Dr. Hamlyn-Harris for identification. 
A close ally of 0. Macleayi, Bates 1 , it can be distinguished by the 
following characters : — Prothorax less rounded, wider in front of 
middle (in 0. Macleayi it is widest at or behind the middle), lateral 
channel smooth (in 0. Macleayi distinctly rugose), posterior angles 
strongly produced into an acute tooth (in Macleayi very slightly 
produced and not dentate) ; the elytra! border is much narrower, 
while the surface sculpture is much more pronounced as to costas, 
reticulation, and punctures. 
Type in the Queensland Museum.
