BY REV. T, BLACKBURN. 519 



This species is distinguished from all its immediate allies by the 

 front part of its pronotum ver}^ conspicuously retuse, with the 

 middle of the retuse front topped by a distinctly bifid obtuse 

 (but by no means strongly prominent) protuberance. It differs 

 from all the preceding species (except B. kevipes, Blackb.) also by 

 the punctureless surface (excepting the extreme front and the 

 row of setiferous punctures) of its hind femora; and from B, 

 Icevipes by, inter alia, the extero-front angles of the frontal wings 

 quite rounded off, its frontal elevation consisting of a short 

 transverse carina, its pronotum more closely punctulate in the 

 neighbourhood of the front angles and the 14th and 15th striae 

 of its elytra very evidently better defined in their front part (i.e., 

 not becoming mere rows of subobsolete punctures).

Fem.C?). Breve; subrotundatum ; nitidum ; supra glabrum ; 

 subtus hirsutum; obscure rufobrunneum; mandibulo sinistro 

 (superne viso) extus vix sinuato; capite fere ut B. mandihularis, 

 Blackb. (feminse 1), sed fronte magis plana minus subtiliter punc- 

 tulata, eminentia frontali ut carina arcuata perbrevis elevata; 

 oculis manifesto granulatis; prothorace fortiter transverse, supra 

 sequali (foveis sublateralibus exceptis), latera versus (et postice 

 in medio sparsissime) acervatim in^qualiter punctulato; scutello 

 Isevi ; elytris fortiter 15-punctulato-striatis, striis 14* 15^que 

 antice confluentibus, interstitiis sat angustis manifesto convexis; 

 femoribus posticis subtus fortiter sparsim punctulatis ; tibiis 

 (exempli typici) carentibus. Long. 4f, lat. 2|- lin. 



Differs from all the preceding species (of this Group) by the 

 14th and 15th striae of its elytra coalescing at a distance from 

 their base of about one-sixth of the length of the elytra and 

 being thence to the base a single row of punctures which are not 

 smaller nor less strongl}^ impressed than in the hinder portion of 

 their length. This species is exceptionally nitid among its con- 

 geners of the Third Group, and its elytral interstices are excep- 

 tionally narrow and convex. I conjecture it to be of the sex 

 that I regard as the female, on account of its f rons being scarcely
