192 ON THE CARENIDES (FAM. CARABID^F.),' 



ohesus, Macl., the male has the elytra much more circular in 

 shape, and more emarginate at the base than the female. Its 

 constant characters are the lobate prothorax and bipunctate elytra. 

 The dimensions from a number of specimens before me may be 

 given as follows : — 



$. Length 34-42, breadth 16-19-5 mm. 

 $. „ 37-44 „ lG-.5-17-5mm. 



Hah. — Yilgarn, Coolgardie, Murchison District (on authority 

 of Mr. French); Kalgoorlie (G. W. Froggatt).

I have no doubt that Sir William Macleay bestowed the name 

 Carenum digglesi on the species that Westwood had previously 

 named C. spencii.
