thence to the apex and rather abruptly, subangularly sinuate at 

 apical third; apex strongly arcuate, fully three-fourths as wide as 

 the base ; disk with rather small but deep, sparse and perforate 

 punctures, becoming slightly larger but scarcely denser and un- 

 evenly distributed on the flanks. Elytra at base scarcely one-third 

 wuder than the prothorax, quite distinctly more than twice as long, 

 gradually ogival to the apex, the sides becoming scarcely parallel 

 toward base ; humeri obtusely rounded and rather prominent, 

 obliquely truncate at base; disk with unimpressed series of some- 

 Avhat large, extremely remote and very feeble punctures in basal 

 half only. Length 3.0-3.7 mm.; width 1.3-1.7 mm. 



Indiana and Illinois. The series before me consists of eleven 

 specimens ; there is also a large series in the cabinet of Mr. Jiilich. 

 This species is allied to aerea, but differs in its larger size and more 

 robust form, in the much coarser punctures of the disk of the pro- 

 notum, and in the elongate impressed line of the vertex.

Narrowly oval, convex, highly polished, bright aeneous in lustre, 

 glabrous, each puncture with a minute seta ; head, beak and legs 

 dull, finely, strongly granulato-reticulate. Head and beak not 

 coarsely but closely and conspicuously punctate, without distinct 

 frontal fovea. Prothorax slightly wider than long, rather abruptly, 

 moderately inflated at the middle, thence slightly narrower to the 

 base; sides convergent and rather broadly, deeply sinuate to the 

 apex, which is strongly arcuate and about three-fourths as wide as 

 the base ; disk with minute feeble sparse and evenly distributed 

 punctures which become larger, deep and rather close-set on the 

 flanks, but rather uneven in distribution and almost w^anting toward 

 base. Elytra at base two-fifths wider than the prothorax, two and 

 one-half times as long, the apical half evenly gradualh^ and acutely 

 ogival, the sides becoming parallel and nearly straight thence to the 

 base; disk with unimpressed series of rather small, remote but dis- 

 tinct punctures in basal third only, the series feebly impressed near 

 the sides ; remainder of the surface with scarcely a trace of punc- 

 tuation. Length 2.2-2.8 mm. ; width 0.9-1.25 mm. 



New Jersey, Iowa and Texas. The measurements given are the 

 extremes of a very large series. The sutural series of punctures is 

 generally visible to a little beyond the middle.
