J/ab. — Kalgoorlie, West Australia (Mr. F. H. Duboulay). 

 Two specimens, the sexes, under examination, are even more 

 convex than the preceding species, with somewhat similar

 Gory, its pronotum is much more convex and enlarged late- 

 rally, while its apical sculpture and elytral pattern are quite 

 different. Types in the author's coll.
