the same group as B. eqidnus and B. taeniahcs Pasc. It differs 

 from B. Pascoei in being smaller, in having no trace of frontal 

 impressions, in the thorax being longer and more pointed at the 

 posterior angles, in having the space between the thoracic im- 

 pressions punctate, in having two short costse between the hinder 

 thoracic impressions and the base, and in the elytra being of a 

 piceous colour and more strongly costate.

Head and thorax black, subnitid, and coarsely but not densely 

 punctui'ed, the latter nearly square and with a large oblong space 

 in the middle, surrounded except at the base which is open with 

 a broad well marked depression. Elytra red, nitid, finely punc- 

 tato-striate with the interstices finely costate, and a broad sutural 

 black vitta. 



This pretty little species approaches evidently to the group 

 in which Mr. Pascoe places the species B. vittatus, musivus, and 

 tnerus.

Red, nitid. Head broad and triangular, with a deep oblique 

 impression ou each side in front of the eyes, and a few punctures 

 on the forehead and vertex. Thorax scarcely so broad as the 

 head, longer than the breadth, finely serrated on the sides, and a 

 little narrowed at the base with the anterior angles acute, the 

 posterior obtuse, and with two crooked interrupted punctured 

 striae on the disc. Elytra elongate, sub-depressed, not broader 

 than the thorax, parallel-sided, rounded at the apex and punc- 

 tato-striate, with a black fascia behind the middle. 



This species has not got the advanced mandibles of P. man- 

 dibularis, nor do the antennas agree with the generic characters
