Species of the Atlantic slope 6 



6 — Rather narrowly oval, strongly convex, polished, dark rufo-testaceous through- 

 out, the sterna of the hind body and basal half of the elytra black, the 

 pale apex more advanced on the suture ; pubescence very sparse ; antennoe slen- 

 der, not quite half as long as the body; prothorax not more than three-fifths 

 wider than long, subangularly inflated at the middle, the apex but little narrower 

 than the base, the basal impression rather feeble and medial ; disk strongly, 

 longitudinally convex in prolile, the punctures small and very sparse ; elytra two 

 and one-half times as long as the prothorax and distinctly wider, the sides evenly, 

 strongly arcuate, the apex rather acute, punctures fine and very sparse. Length 

 1.35 mm.; width 0.63 mm. District of Columbia distincta, sp. nov. 



More broadly oval, strongly convex, nearly similar in coloration to the preceding but 

 paler testaceous, the elytra black in basal half, less on the suture ; antenna; 

 slender and half as long as the body; prothorax shorter and more transverse, 

 three-fourths wider than long, the sides strongly arcuate, the apex but little nar- 

 rower than the base, similarly feebly impressed at base, the punctures fine and 

 distinctly less sparse ; elytra distinctly wider than the prothorax and about three 

 times as long, subangularly inflated and widest at basal two-fifths, the ape< 

 acutely rounded ; punctures fine and rather sparse but much less so than in 

 distiiiita, the pubescence similarly very short. Length 1. 4 mm.; width 0.7 mm. 

 Iowa (Independence) divisa, sp. nov. 



7 — Second antennal joint subequal in length to the third, both elongate ; base of the 

 prothorax transverse and rectilinear or very feebly arcuate 8 



Second antennal joint much longer and generally thicker than the third, frecjuently 

 as long as the third and fourth combined ; base of the prothorax variable, some- 

 times distinctly lobed in the middle 16 



8 — Base of the prothorax, at the middle, finely beaded and fre(|uently abruptly thougli 

 feebly elevated 9 



Ease of the prothorax reflexed but not beaded at the middle of the base. Body pice- 

 ous, the elytra paler, sometimes wholly pale, rather stout, oval, strongly convex, 

 highly polished and very sparsely clothed with short recurved pubescence ; head 

 subimpunctate, the eyes rather small ; antennje slender, a little less than half as 

 long as the body ; prothorax scarcely two-thirds wider than long, widest and 

 broadly angulate at the sides just before the middle, the apex very much nar- 

 rower than the base ; surface strongly convex, minutely and very sparsely 

 punctate, the basal impression broadly concave and gradually evanescent later- 

 ally ; elytra at base slightly wider than the base of the prothorax, widest, but 

 not inflated, before the middle, where they are a third wider than the prothorax, 

 not quite three times as long as the latter, oval, rather pointed behind, strongly 

 but very sparsely impresso-punctate. Length l. 6-1. 75 mm.; width 0.72-0.88 

 mm. New Jersey gilvipennis, sp. nov- 



9 — Body oval in form and strongly convex 10 



Body oblong or oblong-oval inform and subparallel at the sides 15 



10 — Juxtahumeral impressions at the base of the elytra very large and conspicuous, 

 though shallow. Body short and very stout, dark rufo-piceous in color through- 

 out ; legs and antennpe pale, the latter moderately slender and nearly half as 

 long as the body ; prothorax well developed, strongly convex, fully three-fourths
