 rate, about as broad as long, not petiolate ; abdomen very convex

So far only one species has been recorded from within our 

 limits.

Professor Emery has separated the Karennee form as a sub- 

 species, P. brevispinosus subsp. sulcatus. It is slightly larger than 

 the typical species, has the spines on the pronotum slightly 

 longer, and the punctures on the head and thorax running into 

 sulcations.

 immediately behind the flattened top of the pronotum is almost
