Bradycellus promtus, Er, 



A species which corresponds very fairly with Erichson's descrip- 

 tion of Harpalus promtus and which ajipears to have all the 

 essential characters of Bradycellus (to which the Baron de Chaudoir 

 refers that insect) is not uncommon in S. Australia. It varies a 

 good deal in colouring, — the dark parts in numerous examples 

 (perhaps more or less immature) being reddish or pitchy-red. 



Harpalus convexiusculus, Macl. 



Sir William Macleay's statement that the profchorax in this 

 species has its lateral margins " furnished with several setigerous 

 punctures " suggests the probability of its belonging to the 

 Feronides rather than the Harpalides.

The head scarcely differs from that of H. jnge?; Blackb., except 

 in the clypeus being a little less emarginate anteriorly, so that the 

 trilobed outline of the head is slightly less developed. The pro- 

 thorax is very nearly double as wide as long (i.e. as 13 to 7), its 

 base slightly more tlian half again as wide as its front which is 

 moderately emarginate with angles very little j^roduced ; the sides 

 (viewed from above) appear to be somewhat straight in the hinder 

 half, thence to converge arcuately to the front and to form right
