Leacli, it may further be distinguished from the other Feronice 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- 

 na; and feet jiale testaceous.^ 



Lentjth two fifths of an inch. 



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

 beneath castaneous. Palpi and antenua3 pale testaceous or ochreous. Tho- 

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

 broad external margin reddish brown; dorsal stria? minute, basal indentations 

 obsolete. Elytral strite impunctured, interstitial lines flat, the submarginal 

 serrato-punctate within, punctures ocellated; tip of the elytra entire, 

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

 Feet pale testaceous. 



It must closely resemble the Feronia gregaria, Say, but diflers in having 

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

 antennas. It has not the pale elytral margin of F. tenninata, Say, nor the 

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

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

 sinuated. Sent by Eev. L. W. Leonard, from Dublin, N. H.

Subgenus A nchomev us. 



United to Callistus by Latroille, Avho informs us that it is distinguished 

 from Ar/oniim by having the thorax heart-shaped and truncated at base and 

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

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

 thoracic angles acute; and (in which it diflers from Callistus) in having the 

 thorax glabrous, the labrum transversely quadrate, entire, and the body 

 somewhat depressed. 



Our species exhibits the above characters, on which I must depend lor 

 the pi'opriety of arranging it in the genus, no foreign types of which 1 have 

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

 named by him, F. cinclicollis and dccentis. The decora is about the size of 



* C gregarius.
