Leach, it ma)- further be distinguished from the other Feronlce by its pecti 

 nated nails, and from Lebia and Cymindis, with which it agrees in this 

 respect, by its broader subquadrate thorax. The feet are remarkably 

 elongated, and- the posterior pair are unusually remote from the interme 

 diate ones. 



C. *piceus. Piceous; thorax, at the sides, and body beneath paler; anten- 

 nas and feet jiale testaceous.^ 



Length two fifths of an inch. 



Body glabi'ous, polished, impuuctured, above dark chestnut or piceous, 

 beneath castaneous. Palpi and antennaj pale testaceous or ochreous. Tho- 

 rax subquadrate, narrower than the coleoptra at base, the angles rounded; 

 broad external margin reddish brown; dorsal striae minute, basal indentations 

 obsolete. Elytral striaa impuuctured, interstitial lines flat, the submarginal 

 sen-ato-punctate within, punctures ocellated; tip of the elytra entii'e, 

 rounded. Sides of the body, beneath, somewhat darker than in the middle. 

 Feet pale testaceous. 



It must closely resemble the Feronia gregarid, Say, but difiers in having 

 a narrower thorax not pale at base, and with ditFerently colored feet and 

 antennae. It has not the pale elytral margin of F. ir.nninaki, Say, nor the 

 broad thorax of that species; and varies from F. autumnalis, Say, in many 

 respects, besides being much larger, and having the tips of the elytra not 

 sinuated. Sent by Kev. L. AV. Leonard, from Dublin, N. H.

Subgenus Anchomenus. 



United to CaUbtus by Latreille, who informs us that it is distinguished 

 from Agonum by having the thorax heart-shaped and truncated at base and 

 apex. Leach says that the characteristics of this genus of Bonelli are, to 

 have the third and fourth joints of the palpi equal, sub-acute; the basal 

 thoracic angles acute; and (iu which it difiers from Calllstus) in having the 

 thorax glabrous, the labrum transversely cpuidrate, entii-e, and the body 

 somewhat depressed. 



Our species exhibits the above characters, on which I must dei)cnd for 

 the propriety of ai-ranging it in the genus, no foreign types of which I have 

 seen. Congeneric is Feronia decora, Say, and jjrobably also the species 

 named by him, F. cincticoltis and decentis. The decora is about the size of 



' C. gregarius.
