slightly emar-inate, and with a distinct, transverse carina, clypeus 

 truncate at tip, attenuate laterally, and with the basal angles produced 

 into a very sharp triangle, close to the apical margin there is a broadly 

 triangular carina reaching from the basal angles to a short distance 

 from the tip, and strongly reflexed at apex, a httle past the median 

 part of the head, which is there depressed, there is another transverse 

 carina extending for half the width ; prothorax moderately sinuate m 

 the anterior part, apical margin simple in the centre, it is covered 

 with deep, equi-distant ' punctures which become scarcer in the 

 median posterior part of the disk, there is a median sub-orbicular 

 impression close to the apical margin which varies in depth, but is 

 nevertheless distinct, and a deep, sub-punctulate, median longitudinal 

 sulcus reaching from about the median part of the disk to near the 

 base ; scutellum deeply and closely punctured for two-thirds of the 

 length ; elytra deeply and closely punctato-striate, eighth stria a little 

 shorter than the ninth, and reaching the apex of the humeral callus ; 

 intervals impunctate, and slightly convex ; anterior tibia3 nine-dentate ; 

 under side and legs densely pubescent. 



Length 7 mm. ; width 5 mm.

" Sub-globose, testaceous red, shining ; head sparingly punctate 

 behind, Tnd having on the vertex a transverse fuscous carina not 

 much raised, and abbreviated on each side, clypeus short, sensibly 

 narrowed in front, slightly reflexed, truncate at the tip, closely and 

 roughly punctate, and bearing a moderately highly raised carina 

 som^ewhat arcuate in the middle, and distinct from the frontal part ; 

 prothorax strongly but sparingly punctured, very convex, and with a 

 very faint impression near the apex ; scutellum sparingly punctate ; 

 elytra very convex, somewhat deeply punctato-striate, and with the 

 intervals smooth; the suture and the outer margins are slightly 

 infuscate ; anterior tibiae ten-dentate. 



Length 9^ mm. ; width 6^ mm."

I have only seen the type of this species, which resembles much 

 B. maculicolle, but there is no fuscous or black patch on the pro- 

 thorax, nor is the head black, and the transverse median carina 

 reaches to the sides, and is situated farther forward.
