 rally distributed in Western Australia. It is in general 

 appearance like G. funereus, but more scaly, and with 

 elytra that may almost be said to be transversely sulcate.

 rounded at the sides, sub-reticulately tubercled above; 

 scutellum very small ; elytra sulcate-punctate, the inter- 

 vals strongly tuberculiform and slightly connected trans- 

 versely, post-humeral spine elongate and acute, median 

 spines rather remote from the suture, the posterior stout
