Dakota. 



The small size, rounded sides and densely, strongly punctured 

 surface of the prothorax, coarse grooves, and very fine distant inter- 

 stitial punctures of the elytra, will probably serve to identify this 

 species, which is of unusually cylindrical form. The prosternum is 

 rather narrowly but quite distinctly impressed, and separates the 

 coxae by a little less than one-half of their own width. The unique 

 specimen is a female. 



37 Bails abrupt a n. sp. — Oblong-oval, convex, rather stout, black 

 throughout, highly polished and with a pronounced aeneous lustre ; setae 

 minute and inconspicuous. Head minutely, very remotely punctate, the 

 beak strongly but not densely or coarsely so, stout, strongly arcuate, scarcely 

 more than three-fourths as long as the prothorax, the antennae inserted a 

 little behind the middle. Prothorax short and transverse, fully three-fourths 

 wider than long, the sides feebly convergent and almost straight to apical 

 third, then abruptly, strongly rounded and prominent, thence very strongly 

 convergent and feebly constricted to the apex, which is feebly arcuate and 

 scarcely one-half as wide as the base, the latter straight and slightly oblique 

 at each side of the small, broadly rounded median lobe ; disk without im- 

 punctate line, the punctures strong and rather dense, about two-fifths as wide 

 as the scutellum and separated generally by about one-half of their own 

 diameters. Scutellum moderate, feebly transverse, scarcely impressed. Elytra 

 large, very slightly wider than the prothorax and fully twice as long, a little 

 longer than wide, hemi-elliptical in outline, the humeri but very slightly 

 prominent ; striae deep, abrupt, even, not very coarse, the intervals flat, fully 

 twice as wide as the grooves, each with a single series of very small, not close- 

 set punctures, the second and third wider and with the punctures more or less 

 confused. Abdomen distinctly but rather sparsely punctured. Prosternum 

 broadly, strongly impressed along the middle, separating the coxae by fully 

 three-fifths of their own width. Length 3.4 mm. ; width 1.65 mm. 



Pennsylvania. 



The unique type is a male, having a large, rather strong impres- 

 sion toward the base of the abdomen. This species resembles 

 deformis, but differs decidedly in its strong aaneous lustre, promi- 

 nent and strongly rounded sides of the prothorax at apical third, 

 and finer interstitial punctures. 



38 Baris tenuestriata n. sp. — Oblong-oval, convex, black throughout, 

 polished, the elytra finely reticulato-granulose and more or less feebly aluta- 

 ceous. Head minutely and not very sparsely punctate, beak three-fourths as 

 long as the prothorax, stout, feebly arcuate, somewhat coarsely, deeply and 

 closely punctate ; antennae robust, funicular joints three to seven transverse, 

 gradually wider, the club moderately robust and almost perfectly continuous 

 in outline with the outer joints of the fuuicle, first joint of the latter scarcely
