by nearly their own widths, with a narrow impunctate spot at the middle. 

 Scutellum small, tumid. Elytra one-third wider than the prothorax, two and 

 one-half times as long, ogival, the sides becoming scarcely parallel at base, 

 the humeri oblique to the base of the prothorax ; disk with fine impressed 

 striae, having moderately small deep elongate and remote punctures, wider 

 than the striae, the intervals equal, strongly, angularly convex, with a feeble 

 series of small punctures at each side of the summit. Abdomen finely, sparsely 

 punctate. Legs moderate ; femora not very stout, the denticle strong, inclined ; 

 tibiae rather slender. Length 4.0 mm. ; width 2.0 mm. 



Indiana. 



Easily distinguishable by the fine even separated punctures of the 

 prothorax, the latter being unusually elongate. A single specimen. 



ACAMPTUS Lee. 



This is a conspicuously distinct and aberrant genus with the met- 

 epimera invisible, the episterna distinct, the anterior coxae large, 

 prominent, contiguous but excavated internally to receive the very 

 short thick beak, the eyes concealed in repose, antennal club solid, 

 and third and fourth abdominal segments short. The tibiae termi- 

 nate in an unusually large internal spur and the tarsi are slender 

 and cylindrical, with the third joint undilated ; the claws are slen- 

 der, free and divergent. The body is narrow and elongate, brist- 

 ling with thick erect clavate setae. The two species may be thus 

 distinguished : — 



Elytra shorter, scarcely more than one-half longer than wide and not twice as 

 long as»the prothorax, the latter broadly and feebly constricted behind 

 the apex ; dorsal bristles short and sparse throughout, the elytral ridges 

 moderate rigidllS Lee. 



Elytra much longer, fully three-fourths longer than wide and more than twice 

 as long as the prothorax, the latter broadly and deeply constricted behind 

 the apex ; dorsal bristles twice as long and very close-set, extremely 

 robust and squamiform ; elytral ridges strong. Body elongate, parallel, 

 subcylindrical. Head and beak densely squamose, the latter bristling 

 with erect scales especially toward base, not more than two-thirds as long 

 as the prothorax, the antennae inserted near the middle, the funicle gla- 

 brous, the basal joint about as long as the next two, outer joints gradu- 

 ally thicker, coarctate, club rather small. Prothorax fully as long as wide, 

 the apex broadly arcuate and slightly narrower than the base, coarsely, 

 indistinctly punctate. Scutellum small, distinct. Elytra one-third wider 

 than the prothorax, the sides straight and nearly parallel in basal three- 

 fourths, each with four ridges bearing long erect close- set scales, the in- 

 tervals alutaceous, biseriately punctate. Length 4.3 mm. ; width 1.65 

 mm. New York echinus n. sp.
