5. Of a shorter, more parallel form than g; prothorax 

 (6x7 mm.) not dilated on sides, disc convex, with very feeble 

 collar-constriction and median line; elytra(14 x 9 mm.) more con- 

 tracted posteriorly, not abruptly truncate, sculpture as in (J, but 

 interstices ending about half-way down declivity; undersurface 

 feebly convex, almost flat; apical segment with a deep round 

 median pit; legs moderately long, tarsi simple. Dimensions : 

 (J, 23-5 X 9-5; 9, 22 x 9 mm. 



Jlab. — Queensland, Dalveen(R. Illidge) — S. Queensland(T. G.
