B. Flindersi, sp.nov. 



Oblongo-ovatus ; convexus ; supra testaceus, capite prothacisque 

 disco seneis vel nigroseneis ; elytris fuscis nigro maculatis ; subtus 

 niger, palpis (apice anguste nigro excepto), antennis, prothoracis 

 lateribus et pedibns testaceis ; capite prothoraceque crebrius sat 

 fortiter punctulatis • elytris fortiter punctulato-striatis, interstitiis 

 subconvexis fortius nee crebre punctulatis, apice sat acutis. 



[Long. If line, lat. 4 line. 



I have examined many specimens of this insect without finding 

 any tendency to vary in size. The brassy spot on the prothorax 

 occupies the whole disc save that the anterior margin, or base, or 

 both, may be narrowly testaceous. The black spots on the elytra 

 are placed much as in £. discolor, but generally that near the lateral 

 margin is alone conspicuous, the others being almost lost in a 

 fuscous cloudiness that suffuses the entire disc. The head and 

 prothorax are rather evenly and moderately strongly and closely 

 punctured ; the latter bears traces of the basal end of a longitudinal 

 channel, and the former is a little foveated at the middle of the 

 clypeal suture. The striae on the elytra are nearly as deep as, and 

 the interstices not much less convex than, those of B. duplopimC' 

 iatus, the latter being punctured scarcely less strongly than the 

 prothorax. I^ the male the fifth ventral segment is somewhat 

 roundly truncate, in the female it is roundly emarginate in a some- 

 what upward direction, and two filaments (broken off in most 

 examples) project from the apex of the very small sixth segment. 

 In both sexes there appears to be a very minute tiiangular excision 

 in the middle of the apical margin ol the fifth segment. 



The resemblance of this insect to the European B. luridus is 

 extremely close. It is much smaller and somewhat more elongate, 

 and less convex. In color and sculpture there is scarcely any 

 difi'erence except that the punctures in the elytral stride are smaller 

 and closer. The sexual characters, however, difi'er considerably, 

 and the mesosternal carina is of somewhat even prominence, not 

 raised up at the hinder apex (as it is in B. htridus) into a free erect 

 process. The femora are sculptured at their base as in B. dti2ilo- 

 jncyictahis.
