Canada ; Rhode Island ; Pennsylvania ; Florida. 



This is an abnndant species, distinguishable by its bright jeneous 

 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. CO). Length 3^-4.0; 

 width 1.4-1.6 mm. 



4 B. illtei'Miptlls Say. — Ojiutnim interr.: Journ. Ac. Phil., Ill, p. 2(j4 ; 

 luridus Mills. : Ann. Soc. Agr. Lyons, 18.09, 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 ; antennre 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 bi-oadly, 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 sliglitly beyond the middle lobe ; 

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

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

 Scutellum moderate, minutely punctate. Eli/Ira 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 strise which are very 

 finely and approximately punctured, the series more or h^ss interrujjted ; 

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

 rather sparsel}' punctured, the pubescence moderate in length, fine, rather 

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



M(,/c. — Anterior tarsi strongly, intermediate more feebly dilated and densely 

 spongy-pubescent beneath ; abdomen narrowly and almost imperceptibly 

 iiattened in the iniddle toward base. 



Length 4.6-5.2 mm. ; width 2.0-2.4 mm.
