others in our fauna. I observe in tins and the three following species a j>e- 

 culiarity, which is extremely rare among Curculionida, and in f.ic am-nig 

 RhyncJiophora; the flanks of the i)rot!iorax are very suddenly inflexed, and 

 slightly concave, so that the side margin, though not \\vll dcliucd by a 

 sharp line, is still distinctly indicated.

Middle and Southern States. I have retained this name for a species 

 which is quite distinct from all others in our fauna. The well marked 

 structural characters which enable our species of Baris to be easily sepa- 

 rated, were, however, not perceived by Say, nor by the collaborators of 

 Schonherr, and I am therefore doubtful if the presen! name should be pre- 

 served. As far as I can judge from the descriptions, I his spec es is the one 

 intended by Boheman, founded upon a typical specimen from Florida sent 

 by Say, and on others from Sou'h America. But I am very uncertain if it 

 be the one originally described by Say, and quite doubtful if that original 

 be the same with the one subsequently referred to (Cure. 18), of which it 

 is said that the punctures of the elytra! in erspaces " have a transverse 

 rugulous appearance." In the original d 'scrip. ion (J. Ac. iii, 314), these 

 same punctures are declared to be orbicular. 



Head sparsely punc'ulate, beak finely punc'ured, frontal constriction 

 strong; pro horax strongly but not densely punc ured, scarcely wider than 

 long, slightly narrowed from the, base for two-thirds the length, then more 

 suddenly rounded and narrowed to the tip, which is feebly impressed at the 

 sides. Elytra with deep striae, in erspaces fla , each with a row of very 

 fine punctures, somewhat confused on the third interspace, and nearly ob- 

 solete in some specimens. Prpsternum at the middle broadly but rather 

 deeply sulca'e, and more sparsely punctured. An ennse as usual. Length 

 3.3 ram.; .13 inch. 



The color is black, slightly bronzed.

 Atlantic States, to Kansas. Very closely related to B. interstitiali*, but 



more brassy, smaller and a litile narrower, with the punctures of the pro 

 thorax larger and less distant. The punctures of the interspaces, though 

 fine, are distinct, and arranged in rows, those of the third interspace are 

 not confused. Length 3 mm. ; .12 inch.

Southern States. Narrower, usually smaller, brighter brassy, with the 

 punctures of the prothorax s'.rong, but less dense, and those of the ely'ral 

 interspaces extremely small and distant, placed in single rows. Length 

 2.5-3. 3 mm.; .10-. 13 inch.
