1. A. scolopax (Say), Cure. 26; ed. Lee. i, 295, {Baridius); Boh., Sch. 

 Cure, iii, 699. 



Illinois and Georgia, four specimens; in three of them distinct traces of 

 a smooth dorsal line are seen on the protliorax, but in one the surface is 

 quite uniformly i)unctured. The elytra become gradually wider behind 

 the base for a short distance, so that the humeri are distinct, though very 

 obtuse. 



2. A. ibis Lee. loc. clt. 365. 



Georgia, four sjjecimens. More convex than the preceding and very 

 similar in form to Fsettdobaris farctus. The humeri are rounded, slightly 

 prominent. 



3. A. naso Baridius nasutii,s\\Jjec. loc. cit. 295. 



One specimen, Kansas, and two from California or Arizona. The elytra 

 are not wider than the protliorax, the stritc are deeper, tl;e interspacea 

 narrower, and each is marked with a line of deep punctures; at the base of 

 the third and fifth inlerspaces are a few whiiish hairs. 



I regret to have been the cause of confusion by having previously des- 

 cribed another Baridius nasutus from Tejon, Cal., (Pr. Ac. Nat. Sc. Phil. 

 1859, 79). On reexamining that species I found that as the pygidium was 

 covered by the elytra it did not belong to Baris; though I inadvertently 

 forgot the name I had given to the species at the time I prepared the syn_ 

 opsis of Baridius, in consequence of having transferred it to another box 

 with the other species of C'entrinus. 



4. A, anthracina (Boh.), Sch. Cure, iii, 727 (Baridius). 



Oblong oval, shining, black, head less shining, finely punctured, beak as 

 long as the pi-othorax, rather slender, moderately curved, finely punctured 

 above, coarsely punclured at the sides; club of antennae rounded oval, shi- 

 ning only at the base. Prothorax coarsely and deeply punctured, more 

 densely at the sides, which are nearly parallel for two-thirds the length, 

 then suddenly rounded and narrowed to the apex, which is cons'ricted at 

 the sides; dorsal line wanting. Elytra with deep stri;e, interspaces moder- 

 ately wide, flat, each with a row of shallow punctures, extending across 

 the interspaces, as distinct rugte. Prosternum deeplj- sulcate, with tlie 

 groove sharply defined and nearly smooth. Length 3.8 mm. ; .15 inch. 



One specimen from Florida; Messrs. Hubbard and Schwarz. This spe- 

 cies has the rather flat upper surface of true Baris, and is quite diflferent in 

 form from the other three above mentioned.
