This species is easily recognizable by the characters cited 

 in the tabulation. I have before me specimens from North 

 Queensland, Port Darwin, and North-West Australia which 

 present slight differences, inter se, suggesting the possibility 

 that investigation of more numerous examples may indicate 

 their being distinct closely-allied species. In the Queensland 

 specimen (the type) only, the pronotum is distinctly canalicu- 

 late, while that from North- West Australia only has some 

 traces of elytral striation. It would not, however, be wise 

 to treat them as specifically different without further evidence. 

 The trilobed outline of the head in this species is strongly 

 developed and divided.

This species bears considerable resemblance to E. sollici- 

 tus, Blackb., but is easily separated from it by its very differ- 

 ent hind claws, which are somewhat near the border line
