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 punctured. The elytra become graduallj^ wider behind 

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

 obtuse. 



2. A. ibis Lee. loc. cit. 365. 



Georgia, four si)ecimens. More convex than the preceding and very 

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

 prominent. 



3. A. naso Baridius nasutuslXje^c. loc. cit. 295. 



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

 are not wider than the protliorax, the striae are deeper, tlie interspaces 

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

 the third and fifth interspaces are a few whiiish hairs, 



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

 cribid another Baridius namtiis 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_ 

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

 with the other species of Gentnnus.

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

 long as the protliorax, ratlier slender, moderately curved, finely punctured 

 above, coarsely' punctured at the sides; club of antenna' rounded oval, shi- 

 ning only at the base. Protliorax 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 constricted at 

 the sides; dorsal line wanting. El3tra with deep strite, interspaces moder- 

 ately wide, flat, each with a row of shallow punctures, e.xtending across 

 th(! interspaces, as distinct ruga?. Prosternum deeply sulcate, with the 

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



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

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

 form from the other three above mentioned. ^^ '2 =. ///^^/^^,)
