AMERICAN COLEOPTERA. 247 



[I would observe in addition, that while D. Isevijynmis'has the upper 

 surface tinged with violet it differs from all the other species, not only 

 by the feebly striate elytra, but by the labrum being much less emar- 

 ginate; both mandibles are without tubercles; the names attributed 

 to Nos. 8 and 9 do not seem to agree with my determinations of the 

 same species.] 



Feronia carbonaria Dej. Sp. Gen. iii, 283. — LeConte has twice mistaken this 

 species : 1st he placed it (Ann. Lye. iv, 336) as synonymous with caudicali.t 

 Say, which is an Hypherpes, and afterwards, (Journ. Ac. Nat. Sc. Phil. 2ud, ii. 

 243) as luctuosa Dej, which is equivalent to P. abjectus Lee. 



[The name carbonaria has been inadvertently omitted in my List, 

 and it is really a synonym of muta Say, as determined by Baron Chau- 

 doir (vide infra); the confusion in my mind with regard to F. lucfuosa 

 Dej., which as I was afterwards informed by Baron Chaudoir (Say's 

 Entom. Writings, ed. Lee. ii. 480) is the same as my F. ahjcctiis, re- 

 sulted from the fact that the description of Dejean will apply equally 

 to both species; carbonaria cannot be referred to the present species 

 since the description states that the outer stria of the basal impression 

 is wanting; it is in caudicalis short, and very close to the carina of the 

 angle, which is more distinctly defined than in the smaller species, F. 

 luctuosus. About F. caudicalis Say, I may observe that Dr. Harris 

 gave me specimens of the species under consideration, as having been 

 compared with Say's type ; moreover the expression "space of the 

 basal angles depressed and punctured," and the fact that the insect 

 is winged, absolutely forbid the reference of Say's description to any 

 species of Hi/pherpes. The synonymy as printed in my List is there- 

 fore correct.] 



Selenophoras parumpunctatus Dej. iv, 104. [This species, described by De- 

 jean as being perhaps from the West Indies, has been identified by Dr. Zimmer- 

 mann as the common small Southern species, S.faiuus Lee, New S^jec. Col. 

 (Smiths, Inst.), 17.]

Ochthedromus plagiatus Zim. — Length 2 lines. Somewhat larger than 0. 

 niger, but of the same general form; dark-green, black beneath; mouth, base 

 of anteuute, and legs ferruginous-yellow ; frontal grooves parallel, simple, deep ; 

 prothorax cordate, strongly narrowed behind, with rectangular hind angles, ru- 

 gosely punctured at the hind margin, with deep basal impressions, and distinct 

 carina at the angle. Elytra convex, much broader than the prothorax, with 7 

 strongly punctured dorsal strias, which are obliterated behind, and marked in 

 front of the tip with a large common reddish-yellow oblique spot. — Maryland.
