-and hind margin of the 5th ventral segment are quite simple. In 

 the females that I have seen the apical filaments are wanting, but 

 they may have been accidentally broken off. From B. Australice, 

 Muls., this insect may be known by its elytral sculpture not 

 becoming feebler near the apex ; and from B. externespinosus, 

 Fairm., by the two apical spines of each elytron being about 

 equally developed.

Resembles B. majusculus, but with the puncturation of the head 

 and pre thorax verj/^ much finer and more sparing. The punctures 

 are of a fuscous color, but otherwise those parts are almost 

 unicolorous. The sculpture of the elytra is scarcely feebler near 

 the apex than in front ; their apex is only minutely emarginate, 

 with the sides of the emargination scarcely spiniform (probably a 

 variable character), and their infuscation is very undefined, show- 

 ing no tendency to be concentrated into a fascia. On the underside 

 the punctured part of the femora is inf uscate, and the segments of 

 the l)ind body are transversely marked with blackish-brown. The 

 specimen before me is a female, and presents no very conspicuous 

 sexual character that I can find beyond the slenderness of the 

 front tarsi. The fine sparing puncturation of the head and 

 prothorax (a little finer on the clypeus but other \\^ise even in 

 distribution and intensity) seems the most distinctive character of 

 this insect amongst those of its Australian allies that have the 

 elytra emarginate at the apex. From B. Australice, Muls., (in the 

 description of which the puncturation of those parts is not
