88. B. COiitractiiin Say. — Form slender, elongate, convex; color nigro- 

 seneous, often tinged with green, the elytra usually with the apex and a line along 

 the margin more or less distinctly testaceous. Head finely alutaceous, as wide as 

 the thorax at apex ; palpi rufo-piceous or piceous; antennse scarcely one-half as 

 long as the body, dark fuscous, the basal joints sliglitly paler. Prothorax sub- 

 cordate, nearly one-half wider than long, distinctly narrower at base than apex ; 

 apex nearly truncate ; median line fine, abbreviated before and behind ; trans- 

 verse impressions feeble ; basal impressions small, bistriate, the outer stria close 

 to the angle; sides with the margin very narrowly reflexed, arcuate to base; 

 hind angles obtuse, but not rounded, not carinate. Elytra slightly wider than 

 the thorax, elongate, oblong-ovate, subparallel, striate nearly as in const ricf urn ; 

 intervals nearly flat, the third with the first dorsal puncture about one-third from 

 base, the second about one-third from apex. Beneath piceous or nearly black, the 

 abdomen sometimes dark rufous. Legs rufous. Length .18-.24 inch; 4.5-6 mm. 



Very close to constrictum, but more slender and elongate and more 

 convex. The thorax is proportionally somewhat longer, with the 

 sides arcuate to base and the hind angles obtuse and not carinate. 



It seems to be confined to the more eastern portions of the country. 

 occurring near the sea-coast from Massachusetts to Florida. I have 

 seen specimens from as far West as Ohio and Tennessee. 



89. B. dejectnin Casey.— Form slightly elongate, depressed. Head and 

 tborax nigro-feneous, shining; elytra brownish piceous, slightly seneous. Head 

 not alutaceous, scarcely as wide as tbe thorax at apex; palpi rufo-piceous; an- 

 tennae nearly one-half the length of the body, rufo-piceous. scarcely paler at base. 

 Prothorax slightly subcordate, less than one-half wider than long, slightly nar- 

 rower at base than apex, more or less rugose at base ; apex nearly truncate ; me- 

 dian line fine, extending between the transverse impressions, which are distinct ; 

 basal impressions broad, moderately deep, bistriate; sides with the margin nar- 

 rowly reflexed, arcuate, scarcely sinuate in front of the hind angles, which are 

 obtuse, but not rounded, and finely carinate. Elytra slightly wider than the 

 thorax, elongate, oblong-ovate, subparallel, moderately finely striate ; strise entire, 

 distinctly punctate to behind the middle, the fifth slightly grooved at tip; inter- 

 vals nearly flat, the third with the first dorsal puncture about one-third from base, 

 the second about one-fourth from apex. Beneath piceous or nearly black, some- 

 times more or less tinged with rufous, shining. Legs rufous or rufo-piceous. 

 Length .16-.18 inch ; 4-4.5 mm. 



This species seems to lead from contractum towards ohtmangulmn, 

 etc. It is rare in collections, but specimens of both sexes have been 

 seen. 



It is known to me from Arizona and Oregon. I have also received 

 one example labeled " Nebraska." 



90. B. grandicolle Lee. — Form moderately elongate, convex ; color black, 

 slightly aeneous, shining. Head not alutaceous, slightly narrower than the thorax 

 at apex : palpi black ; antennse less than one-half the length of the body, black. 

 Prothorax subquadrate, about one-half wider than long, narrower at base than 

 apex, sliglitly rugose at base; apex truncate: median line very fihe, subentire;
