HARPALIISLE 243 



Elongate, subparallel, moderately convex, black, the elytral suture and 

 sides posteriorly feebly rufescent; under surface black, the legs obscure 

 rufous; surface rather shining though feebly alutaceous; head smooth 

 and convex, fully three-fourths as wide as the prothorax, with promi- 

 nent eyes, the vertex with a feeble central puncture, the frontal 

 foveae deep, oblique, attaining the eyes; antennae notably stout, 

 black, half as long as the body, the basal joint alone rufous; prothorax 

 a third wider than long, widest at apical third, the sides strongly 

 rounded, oblique and feebly arcuate posteriorly, finely sinuate very 

 near the basal angles, which are obtuse but sharp and minutely 

 prominent; base feebly arcuate, wholly unmargined, equal in width 

 to the sinuato-truncate apex; surface nearly even, with feeble 

 anterior impression and very finely reflexed along the sides, some- 

 what flattened and opaculate latero-basally but impunctate, the 

 stria fine and subentire; elytra one-half longer than wide and two- 

 fifths wider than the prothorax, parallel, with feeble arcuate sides 

 and gradually circularly rounded apex, the sinus wholly wanting; 

 striae fine but rather strong; intervals flat or virtually so throughout, 

 not more convex at tip; discal puncture completely wanting; lateral 

 line of foveae broadly interrupted medially; hind tarsi rather short, 

 slender, three-fifths as long as the tibiae, the first four joints uni- 

 formly decreasing in length, the first much shorter than the fifth. 

 Length (d 71 ) 4.3 mm.; width 1.5 mm. New York (Lake Champlain), 

 and Ontario (Montreal). Lake Superior, LeConte. [Geobcemis 

 cordicollis Lee.] cordicollis Lee. 



The anterior tarsi of the male are only slightly swollen and appear 

 to have two rows of elongate inconspicuous squamae beneath, the 

 middle tarsi undilated and unmodified. The absence of a discal 

 puncture on the elytra is an important character not specially 

 alluded to by LeConte, although no puncture is mentioned in his 

 description. The above described example, which I took at Bluff 

 Point, may be smaller than the type of LeConte, though the pub- 

 lished measurements are probably excessive, but it appears to be 

 the same specifically; the Montreal specimen, recently received 

 from Mr. Knaus, is precisely similar to the New York representa- 

 tive. It is a remarkable species and demands generic isolation in 

 my opinion. 



Stenocellus n. gen. 



The numerous species of this genus may be distinguished at 

 once from Bradycellus by their more slender elongate parallel and 

 subdepressed form. The prothorax is as in the preceding in general 

 form, but is always more or less impressed and punctate latero- 

 basally and, as in Triliarthrus, may have the basal angles either
