HARPALIISLE 247 



thorax and sides and suture of the elytra more or less irregularly 

 pallescent; under surface of the prothorax blackish, gradually paler 

 laterally, of the hind body piceous-black; legs pale; head two-thirds 

 as wide as the prothorax, with distinctly larger though not more 

 prominent eyes than in rupestris; antennae notably slender and very 

 moderately compressed, piceous, the first three joints paler; puncture 

 at the centre of the vertex usually strong; prothorax rather trans- 

 verse, fully a third wider than long, of the usual form, widest at 

 apical third and with rounded sides, oblique and feebly arcuate 

 posteriorly, the obtuse angles minutely prominent; stria distinct, 

 subentire, the foveae rather rounded, shallow and closely punctate; 

 base narrower than the feebly sinuate apex; elytra long, more than 

 one-half longer than wide, only two-fifths wider than the prothorax, 

 with strong striae and distinctly convex intervals, the discal puncture 

 near three-fifths; hind tarsi with the first joint distinctly shorter than 

 the next two combined, the fifth as long as the first two. Length 

 (cf 9 ) 3.8-4.2 mm.; width 1.2-1.4 mm. New York and New Jersey, 

 westward to Iowa. [Acupalpus debilipes Say; Bradycellus parallelus 

 Chd.] debilipes Say 



Form less elongate, the coloration nearly as in debilipes but usually not 

 quite so dark, the elytra often broadly testaceous toward the sides 

 and base, the suture always testaceous; under surface and legs similar 

 in color; head nearly similar, the antennae slender, dusky, the two 

 basal joints paler, the third intermediate in color; prothorax similar 

 but rather less transverse, with the base and apex more nearly equal 

 and the foveae more impressed and more coarsely punctate; elytra 

 shorter, generally scarcely one-half longer than wide, relatively a 

 little wider, the striae and intervals similar; hind tarsi slightly more 

 elongate. Length (cf 9 ) 3.6-4.0 mm.; width 1.2-1.5 mm. Rhode 

 Island, New York and Virginia. [Stenolophus cinctus Say].

Body notably pallid above, excepting an elytral blackish cloud, the head 

 infumate in purgatus 12 



II Form and size nearly as in debilipes but not so dark in coloration, the 

 pronotum always clear testaceous but of either paler or darker tint; 

 under surface of the hind body, and usually the median part of the 

 prosternum, piceous-black; epipleura and legs pale; head moderate, 

 with prominent eyes; antennae dusky, gradually paler basally, slender, 

 nearly half as long as the body; vertex without an evident puncture; 

 prothorax nearly as in debilipes but not so transverse, with more 

 evenly rounded sides and with the base but little narrower than the 

 apex, differing especially in having the obtuse basal angles simply 

 not rounded and without the minutely prominent apices of the pre- 

 ceding species; elytra fully one-half longer than wide and nearly 

 one-half wider than the prothorax, testaceous, with a large blackish 

 cloud divided by the suture; hind tarsi slender, moderate in length, 

 with the usual long fifth joint. Length (cf 9 ) 3.6-4.0 mm.; width 

 1.1-1.4 mm. Utah, Colorado and New Mexico. [Geobcenus con-
