The large size, depressed form, and abdomen with only the 

 first dorsal segment covered by the elytra suggest a doubt 

 whether this species might not be regarded as the typo of a new 

 genus Brachypephis as characterised by Lacordaire has not 

 more than three dorsal segments exposed, but there are Aus- 

 tralian species (e.g., binotatus, Murr.) in which a portion of the 

 second segment is exposed dorsally. In the present insect the 

 exposed abdomen is distinctly longer than the elytra. I do not 

 think the abdomen is artificially drawn out, but as I have only a 

 single specimen I cannot be quite certain on the point. Apart, 

 from the characters just mentioned this species is at once dis- 

 tinguishable from its described Australian allies by the con- 

 spicuous little granules thinly dispersed over its head and 

 pronotum. The outline of its prothorax is scarcely different 

 from that of the prothorax of B. planus, Er., but the sides are 

 slightly more rounded near the front.

The Australian BracJujpepli are so little variable in colour and 

 markings that this insect might perhaps be reliably distinguished
