56 AMERICAN COLEOPTERA. 



antiqunm Dej., which is the one by which this species has been pre- 

 viously known. Say's name must, therefore, be restored. 



It occurs in Canada, the New England States, New York, New 

 Jersey, Pennsylvania, the District of Columbia, Virginia, Illinois, 

 Wisconsin, Iowa, Wyoming and Texas. 



19. B. elialceuni Dej. — Form rather more slender and more convex than 

 honeMum; color usually more or less coppery bronze, more rarely greenish or 

 bluish black. Head as in honestum. Prothorax about one-half wider than long, 

 slightly narrower at base than apex, more convex than in honestum, more or less 

 rugose at base; apex truncate, median line distinct, abbreviated in front and 

 behind ; anterior transverse impression usually feeble, the posterior distinct ; basal 

 impressions rather small, moderately deep ; sides with the margin very narrowly 

 reflexed, strongly arcuate in front, distinctly sinuate behind ; hind angles sub- 

 rectangular. Elytra about one-half wider than the thorax, oblong-oval, deeply 

 striate ; strife deeply, almost crenulately punctate nearly to tip, scarcely less deep 

 at apex ; third stria with the first dorsal puncture slightly in front of the middle, 

 the second about one-fourth from apex; intervals convex. Beneath greenish 

 black, shining. Legs rufo-piceous, the femora at base and sometimes the tibiae 

 paler. Length .22-.25 inch ; 5.5-6.25 mm. 



Most nearly related to the preceding, of which I was at first in- 

 clined to regard it as only a variety. It is, however, more convex, 

 and the thorax is proportionally slightly wider as compared with its 

 length, with the apex truncate and the sides more strongly arcuate 

 in front and more deeply sinuate behind. The striae of the elytra 

 are deeper and more deeply punctured, and the intervals more con- 

 vex. It averages slightly smaller in size. 



It occurs in Canada, Massachusetts, New York, New Jersey, Vir- 

 ginia, Ohio, the Lake Superior region, Wisconsin, Iowa and Colo- 

 rado, but seems to be nowhere as abundant as the preceding. 



20. B. blanchardi n. sp. — Form slender, elongate, slightly depressed. 

 Head and thorax nigro-seneous, distinctly tinged with green, elytra feneous. with 

 an ill-defined discal spot about one-third from apex testaceous; surface shining. 

 Head sliglitly wider than the thorax at apex ; palpi piceous or rufo-piceous; an- 

 tennae scarcely one-half as long as the body, piceous, the fii'st joint rufous. Pro- 

 thorax nearly one-half wider than long, slightly narrower at base tlian apex, finely 

 rugose at base : apex feebly emarginate ; median line deep, extending between the 

 transverse impressions, which are distinct; basal impressions rather shallow; 

 sides with the margin narrowly reflexed, arcuate in front, distinctly sinuate 

 behind ; hind angles moderately prominent, acute. Elytra about one-half wider 

 than the thorax, elongate, oolong-ovate, subparallel, moderately finely striate, 

 more finely towards the tip; stria; distinctly punctate to behind the middle, the 

 third with the first dorsal puncture very slightly in front of the middle, the 

 second about one-fourth from apex; intervals nearly flat. Beneath black, shin- 

 ing. Legs rufous. Length .20-. 23 inch ; 5-5.75 mm.
