GENUS ZUPHIUM. 



Z. *bicolor. Pubescent, reddish- bay; coleoptra and abdomen castaneous. 

 thorax canaUculate, elytra sulcate, antennaj comiiressed. 



Length over eleven twentieths of an inch ;— breadth of coleoptra be- 

 tween three and four twentieths of an inch. 



Body reddish bay, with short decumbent, ferruginous pubescence. Head 

 punctured; a lateral longitudinal impression each side near the antennge; 

 neck distinct, impunctured; second and third joints of the antennae nearly 

 equal in length, and with the first obconic ; terminal joint flattened, oblong, 

 rounded at tip ; intermediate joints transverse, gradually broader to the 

 penultimate one, and laterally compressed. Palpi with obconic joints, the 

 terminal ones largest and truncate at tip. Thorax cordate, truncate before 

 and behind, rather wider than long, anterior angles rounded, posterior ones 

 slightly excurved, subacute; disc deeply and distinctly punctured, and 

 longitudinally canaliculate. Coleoptra parallelogramical, basal and exter- 

 nal apical angles rounded, disc chestnut colored, paler at base, widely 

 grooved, the grooves punctured, obsolete at tip; external submargin with 

 a few, remote, larger, ocellate punctures. Body beneath punctured, pectus 

 postpectus and feet reddish bay, ventral segments castaneous. Tarsi with 

 entire joints. Nails simijle. 



This insect must be very rare. The specimen from which this description 

 is taken was presented me by Charles Pickering, M. D., who found it in the 

 vicmity. of Salem. Some doubts^ existing respecting the propriety of plac- 

 ing it in the genus Zuphium, the characters of the species are detailed par- 

 ticularly with reference to elucidating the genus, no other species of which 

 I have seen. 



GENUS HARPALUS.2 



H. %^enceus. Black, punctured, pubescent above; antenna? annulated 

 with reddish-brown and fuscous; thoracic angles rounded; tibia? and tarsi 

 reddish brown. 



Length of the male two-fiflhs of an inch, of the female rather more. 



Body depressed, brownish black, opaque, with distinct large punctures, 

 and short, decumbent, ferruginous pubescence above. Mandibles casta- 

 neous, palpi and three basal joints of the antenna reddish bay, each of the 

 remaining ones of the same color at the tip, and fuscous at base. Thorax 

 distinctly margined, angles rounded, the posterior ones very obtusely; disc 



^ Can it be a//e««oV I have not dissected the mouth, but the palpi liave not the 

 terminal joint obtriangular.
