equal in width to an elytron; sulci short, rather deep; eyes very 

 moderate but prominent, their outline continuing to the neck and 

 without intervening tempora; antennae fuscous, paler basally, mod- 

 erately slender, as long as the elytra; prothorax short, evidently 

 more than one-half wider than long, the sides well reflexed, broadly 

 arcuate, moderately oblique and straight posteriorly, the angles ob- 

 tuse, reflexed and very slightly prominent; sides of the base strongly 

 oblique; anterior impression slightly visible at the middle, the sub- 

 basal deep, broadly angulate; elytra one-half or more longer than 

 wide, two-fifths wider than the prothorax, ogivally rounding in 

 nearly apical half, barely at all wider behind the middle than at 

 base, the sides arcuate; pedicel two-fifths as wide as the base; first 

 and second striae deeply impressed and subequal, the third fine and 

 very feeble, the others obsolete except basally; anterior fovea at 

 basal third to two-fifths. Length 2.0-2.5 nim.; width 0.7-0.88 mm.

obliquus n. sp. 



Form more broadly oblong-oval, rather less convex, shining, the elytra 

 with feeble sericeous lustre; upper surface blackish-piceous through- 

 out, beneath blackish, the epipleura and legs pale; head relatively 

 not so large as in the preceding, three-fourths as wide as the pro- 

 thorax but distinctly narrower than an elytron, the eyes noticeably 

 larger and still more prominent; antennae more slender, dusky, fully 

 as long as the elytra; prothorax in outline and structure as in obli- 

 qiins but not quite so abbreviated, one-half wider than long; base 

 sometimes a little narrower than the apex; elytra broader and rather 

 less convex, one-half longer than wide and two-fifths wider than the 

 prothorax, nearly similar in outline and striation. Length 2.2-2.5 

 mm.; width 0.8-0.92 mm. Rhode Island (Boston Neck). Abun-

coruscus Lee. 



Form oblong-suboval, very moderately convex, shining, the elytra sub- 

 aeneo-sericeous; color as in coruscus; head scarcely three-fourths as 

 wide as the prothorax and not quite as wide as an elytron, the sulci 

 deep, parallel, moderately distant; eyes well developed and prom- 

 inent as in coruscus; antennae similarly slender but shorter, not quite 

 as long as the elytra, blackish, with paler basal joint, the medial 

 joints not quite three times as long as wide; prothorax as in corus- 

 cus but less abbreviated, two-fifths wider than long, the obtuse 

 basal angles similarly reflexed but not at all prominent; side mar- 

 gins more finely reflexed; base fully as wide as the apex, sometimes 

 a little wider; elytra nearly as in coruscus in form and proportion; 

 first stria deep, the second nearly as distinct, the third fine but ob- 

 servable, the others very feebly and only partially glimpsible; an- 

 terior fovea near basal third. Length 2.0-2.4 nim.; width 0.7-0.83 

 mm. Mississippi (Vicksburg) aeneipennis Mots. 



19 Body oblong-suboval, rather depressed and shining, the elytra with 

 feeble sericeous lustre; color uniform reddish-castaneous throughout 

 above, the head black; under surface piceous-black, the legs and epi- 

 pleura flavate; head well developed, as wide as an elytron and four-
