Canada ; Rhode Island ; Pennsylvania; Florida. 



This is an abundant species, distinguishable by its bright aeneous 

 lustre, rather oval form, sparse pubescence and several other char- 

 acters. The hind wings are well developed, being- fully as long as 

 the elytra. 



I have before me a well-defined geographical variety of this 

 species from southern Florida. It is much smaller, narrower, more 

 parallel, rather more depressed and with shorter, more parallel-sided 

 and much more sparsely punctate prothorax, the punctures toward 

 the sides being generally separated by fully twice their own diame- 

 ters. To avoid an increase of names this may be considered as 

 seneolus Melsh (Proc. Ac. Phil., Ill, p. 66). Length 3 T-4.0 ; 

 width 1.4-1.6 mm. 



4 B. intcg riiptus Say. — Opatrum interr.: Journ. Ac. Phil., Ill, p. 264 ; 

 luridus Muls. : Ann. Soc. Agr. Lyons. 1S59, p. 193. — Oblong, rather robust and 

 convex, black, the elytra more or less piceous, moderately shining or sub- 

 alutaceous ; pubescence rather long and dense, cinereous, conspicuous but 

 easily removable. Head transverse, feebly convex, somewhat finely and 

 densely punctate ; upper lobes of eye moderate, separated by about five 

 times their own width ; epistoma broadly, deeply sinuate ; antenna? short and 

 slender, gradually and distinctly clavate toward apex, third and fourth joints 

 subequal in length. Prothorax about three-fourths wider than long, very feebly 

 narrowed from base to apex, the sides for two-thirds the length from the base 

 almost straight and just visibly convergent, then broadly, roundly subangu- 

 late and more strongly convergent to the apical angles, which are rather 

 prominent and acute ; apex broadly emarginate, subtruncate except near the 

 angles ; base broadly arcuate in the middle, distinctly sinuate laterally, the 

 basal angles acute and extending posteriorly slightly beyond the middle lobe ; 

 disk very deeply and not very finely punctate, the punctures moderately 

 dense toward the middle, very dense laterally ; basal fovea? well marked. 

 Scutellum moderate, minutely punctate. Elytra about one-half longer than 

 wide, not distinctly wider, and rather less than three times longer than 

 the prothorax, rather abruptly and obtusely rounded behind ; sides almost 

 straight ; disk with very fine, just visibly impressed stria? which are very 

 finely and approximately punctured, the series more or less interrupted ; 

 intervals sparsely and rather coarsely punctate. Abdomen polished, finely and 

 rather sparsely punctured, the pubescence moderate in length, fine, rather 

 sparse but distinctly visible. Legs and tarsi moderate in length. 



Male. — Anterior tarsi strongly, intermediate more feebly dilated and densely 

 spongy-pubescent beneath ; abdomen narrowly and almost imperceptibly 

 flattened in the middle toward base. 



Len-th 4.6-5.2 mm. ; width 2.0-2.4 mm.
