Coleopterological Notices. 427 



New York ; Minnesota; Colorado; Wyoming. 



The series before me represents a wide range of distribution and 

 exhibits more or less variation, chiefly in coloration and in the 

 extent of interruption of the elytra] series. In some specimens, 

 more especially the eastern, the stria 1 are nearly as widely ami com- 

 pletely broken up as in metallicvs, while those from Colorado have 

 almost completely continuous series. The punctuation of the pro- 

 notiim is rather denser in the western representatives, being some- 

 times almost subconfluent toward the sides, and the pubescence is 

 generally a little denser. One specimen from New York is as 

 strongly seneous as any specimen of metollicua which I have seen, 

 but is more alutaceous in lustre. 



This is an abundant species, distinguishable from metallicus by 

 its broader, more oblong form, more parallel and more densely 

 punctate prothorax and finer less interrupted strial punctuation. 



5 B. I USCIIS 11. sp. — Elongate-oval, rather strongly convex and shining, 

 piceous, the elytra paler, dark red-brown ; pubescence short, Bparse, moder- 

 ately coarse, dark fulvous in color, not very conspicuous. //< ml feebly convex, 

 rather finely, moderately densely punctate ; upper lobes of eye rather large, 

 separated by from four and one-half to five times their own width ; antennae 

 somewhat robust, gradually and rather strongly incrassate toward apex, the 

 tlfird joint very much shorter than the next two. Prothorax about two-thirds 

 wider than long, the apex very distinctly narrower than the base, broadly, 

 feebly emarginate in circular arc, the apical angles not distinctly rounded ; 

 base transverse, the siimations broad and rather strong ; basal angles obtuse 

 but not at all rounded : sides almost evenly and feebly arcuate ; disk densely 

 punctured toward the sides where the punctures are scarcely in mutual con- 

 tact, sparsely so toward the middle, the punctuation not very coarse. Elytra 

 very slightly wider than the prothorax and generally rather more than three 

 times as long ; sides parallel and very feebly arcuate ; disk with rather coarse 

 and distinctly impressed striae which are very coarsely punctate, the punctures 

 very deep and perforate, circular and generally rather distant, being separated 

 by nearly twice their own diameters ; intervals very feebly convex, four to 

 five times as wide as the strial punctures, sparsely and somewhat coarsely 

 punctured. Abdomen polished, sparsely and rather coarsely punctured, the 

 pubescence moderate in length, very sparse, fine, pale but inconspicuous. 

 Legs moderate in length, rather robust. 



Male. — Anterior tarsi strongly dilated, the second joint distinctly longer 

 and rather wider than the third ; intermediate much less strongly but dis- 

 tinctly dilated ; both pairs with densely but rather coarsely squamulose soles ; 

 abdomen rather feebly but distinctly impressed in the middle toward base, the 

 punctuation not very much denser toward the middle of the first segment. 



Length 4.5-5.0 mm. ; width 1.8-2.1 mm.
