82 NOTES ON AUSTRALIAN COLEOPTERA, 



(apart from the absence of elytial sculpture, which may be an 

 unimportant character), by the presence of the prothoracic sulci 

 already mentioned, by its less transverse head on which the 

 frontal sulci are gently curved -outward and forward in front 

 with less approach to an angle than in the other Euryscaphi 

 known to me, and by the non-sinuate hinder portion of the 

 lateral margins of tlie prothorax. The legs do not appear to 

 differ materially from those of E. ohesus, Macl. The elytra are 

 not much wider than the prothorax (as 16 to 14i), and their 

 sides are but little rounded. 



S. Australia; basin of Lake Eyre.

 The elytra distinctly longer than usual in proportion to their 

 width (as 17^ to 15) together with the presence of a large puncture 

 on the hinder part of the disc of each elytron will separate this 

 species from all others described except tatei, Blackb., and 

 sulcicollis, Blackb. It differs from the former by its consideiably 

 more transverse prothorax (| again as wide as long), somewhat 

 more elongate elytra (which are differently sculptured), &c., and 

 from the latter by the frontal sulci much more angulated, 

 differently sculptured prothorax, with sides sinuate behind, &c.
