434 Coleojyfer-ological Notices, IV. 



antennte. Prothorax extremely minutely and remotely punctate, 

 strongly narrowed toward base, the latter scarcely three-fourths as 

 wide as the apex in the female ; disk but slightly longer than wide. 

 Elytra scarcely more than one-half longer than wide, twice as long 

 as the prothorax, and, behind the middle, twice as wide ; strife 

 unimpressed, except feebly near the sides, composed of fine, not 

 very close-set punctures. Legs rather long ; femoral teeth only 

 moderately developed, acute ; tibiae feebly bent toward base. 

 Length 3.3-4.3 mm.; width L3-1.8 mm. 



New York to Texas. Easily distinguishable b}^ the large promi- 

 nent approximate eyes, and fine punctures of the unimpressed ely- 

 tral series. The specimen described is a female. 



10 O. speculator n. sp. — Subcuneate, strongly convex, black and 

 highly polished throughout, the upper surface bristling with very sparse 

 long erect setae, white in color but blackish on the disk of the pronotum 

 toward apex, and forming an even single series on each of the elytral inter- 

 vals, very sparse, shorter, finer and less erect on the under surface, tlie 

 scutellum and sternal parapleurse densely albido-pubescent. Head smooth, 

 scarcely at all punctate, the interocular surface setose, not depressed, slightly 

 dull and remotely punctate; eyes large, prominent, separated by scarcely 

 more than one-third of their own width ; beak in the male short, thick, 

 straight, two-thirds as long as the prothorax, smooth and impunctate above, 

 coarsely punctato-rugose at the sides, and above, in apical two-fifths, having 

 two wide, depressed, dull and reticulate, parallel and rather approximate 

 areas, the narrow interval being im^jressed along the middle ; in the female 

 smoother above at apex ; antennae moderate, the first funicular joint robust, 

 as long as the next two, second a little longer than the third, both elongate, 

 the club elongate, pointed, asymmetrically fusiform. Prothorax distinctly 

 longer than wide, with the apex broadly arcuate ; base nearly as wide as 

 the apex in the male but scarcely three-fourths as wide in the female ; disk 

 almost impunctate, but with a few rather coarse punctures at the sides near 

 the apex. Elytra one-half longer than wide, twice as long as the prothorax, 

 and, behind the middle, distinctly more than twice as wide as the latter in 

 both sexes ; humeri very broadly exposed, obtusely rounded; disk with very 

 feebly impressed series of rather coarse distant punctures, the sutural series 

 more strongly impressed as usual. Lexjs moderate, the femoral teeth rather 

 small, acute. Length 3.5-3.7 mm. ; width 1.4-1.5 mm.

This species, which is represented in my cabinet by three speci- 

 mens, is closely allied to IsevicoUis, but differs in its smaller size, 

 less rolnist form, more abundant and conspicuous white seta^ of the 

 elytra distributed along all of the intervals, and in the coarser
