656 Coleopterological Notices, IV. 



humeri obtusely prominent ; outline behind them hemi-elliptical ; striae rather 

 coarse, deep, remotely, distinctly serrato-crenulate, the intervals differing 

 greatly in width, the third twice as wide as the grooves, the fourth but slightly 

 wider than the latter, flat, minutely but deeply and distinctly punctate, the 

 punctures confused, sparse but becoming closer toward base, forming nearly 

 even single lines on the narrow intervals. Length 3.1 mm. ; width 1.65 mm. 



Florida. 



This species differs from corpulenla in its less obese form and 

 larger antennal club, smaller and quite differently shaped, slightly 

 more conical, much more coarsely, deeply and less sparsely punctate 

 prothorax, with the punctures not isolated beneath at the sides, but 

 forming long rugse ; also in its flatter, still more unequal and less 

 polished elytral intervals, with the punctures less minute, deeper 

 and becoming denser toward base ; and finally, and quite remark- 

 ably, in the form of the mes-epimera, which in corpulenta are 

 gradually pointed upward, but much more truncate and rounded 

 in incompta. The present species is closely allied to ovata, and 

 agrees with that species in all the characters given above to distin- 

 guish it from corpulenta. It is represented by a single female. 



3 Stethobaris ovata Lee— Proc. Acad. Nat. Sci. Phila., 1868, p. 363 

 (Baridius). 



Ovate, polished, black and glabrous, rather strongly convex. 

 Beak moderately slender, strongly arcuate, about as long as the 

 head and prothorax, the antennas inserted just behind the middle, 

 the first funicular joint robust, about as long as the next three, 

 second quadrate, just visibly longer than the third, two to seven 

 small, the club very large, abrupt, elongate-oval, nearly as long as 

 the entire funicle, densely pubescent throughout and with the basal 

 joint composing but slightly more than one-third of the mass, the 

 second long. Prothorax about two-thirds wider than long, the 

 sides feebly convergent and nearly straight to slightly beyond the 

 middle, then broadly rounded and gradually convergent to the strong 

 constriction ; apex tubulate ; base broadly arcuate, the lobe distinct, 

 truncate ; disk rather finely, sparsely and unevenly punctate, the 

 punctures larger along the basal-margin ; impunctate line narrow, 

 entire. Scutellum small, longer than wide, the apex emarginate 

 and the surface impressed posteriorly. Elytra, at a little behind 

 the apex, quite distinctly wider than the prothorax, the humeri large, 

 tumid; outline hemi-elliptical; strias moderately wide, deep, re- 

 motely punctate, abrupt, not at all crenulate, the intervals wide,
