580 NOTES ON AUSTRALIAN COLEOPTERA, 



from the side, owing to the lateral slope of the elytra, they appear 

 as fairly defined tubercles. The whole surface of the elytra is 

 seriately foveolate and the 2nd row of fovese (from the suture) is 

 placed so that a large fovea occupies the upper surface of each 

 quasi-tubercle. The largest of these quasi-tubercles is the hind- 

 most and they become gradually smaller forward and are continued 

 quite to the apex of the humeral processes, until they are little 

 more than large granules ; if all these be counted in the row it 

 consists of about 15 quasi-tubercles and granules. This peculiar 

 sculpture distinguishes the present species from all previously 

 described. The apical ventral segment is similar to that of the 

 smaller and narrower sex of B. luguhris.

I have seen a good many examples of this insect, all of which 

 have in the inner elytral series only three large somewhat com- 

 pressed tubercles which are somewhat directed outward; this 

 character will distinguish it from all its described congeners except 

 granulatus, Pasc, and validus, Blackb. ; the prothorax of the 

 former of these is described as " baud cristatus," while the latter 

 inter alia has the scape of the antennae extremely short. In 

 the present species the prothoracic crests diverge from the front
