HARPALIISMS 267 



anteriorly, strongly converging and nearly straight thence to the 

 base in more than basal half; base feebly arcuate, much narrower 

 than the broad sinuato-truncate apex; basal angles very obtuse, with 

 their apices narrowly rounded; surface feebly impressed and with a 

 few distinct punctures near the hind angles, the stria fine but strong, 

 not quite entire; elytra but little more than a third longer than wide, 

 very broadly obtuse and with vestigial sinus at apex, the sides 

 distinctly arcuate, two-fifths wider than the prothorax; striae very 

 fine and superficial, the scutellar extremely short and feeble ; intervals 

 flat, the discal puncture behind two-thirds; lateral line of foveae 

 interrupted medially. Length (G? 9 ) 2.2-2.8 mm.; width 0.95-1.1 

 mm. Rhode Island. [Stenolophns hydropicus Lee.]. 



hydropicus Lee. 



Body much more elongate, shining, rather convex, deep black, the pro- 

 thorax dark rufo-testaceous; legs pale flavate; head but just visibly 

 narrower than the prothorax, the neck rather long; eyes moderate, 

 longer than the neck behind them and very prominent, very much 

 larger than in hydropicus; antennae more slender, distinctly shorter 

 than the elytra, blackish, the basal joint pale; prothorax a third to 

 nearly two-fifths wider than long, the sides more evenly rounded 

 than in the preceding, though becoming gradually nearly straight 

 posteriorly; base feebly arcuate, with very obtuse and narrowly 

 rounded angles and but very little narrower than the sinuato- 

 truncate apex; surface with fine, not very strong, subentire stria, the 

 foveae short, sublinear, broadly and moderately impressed and with 

 a very few punctures, the surface thence to the sides, almost as far 

 as the middle, deplanate; margins very finely reflexed; elytra much 

 longer than in hydropicus, one-half longer than wide and one-half 

 wider than the prothorax, only feebly inflated posteriorly, the sides 

 broadly arcuate, the apex subcircularly obtuse, each apex straight and 

 oblique; striae very fine, the scutellar very short, oblique, rather 

 distinct; intervals flat, perhaps just visibly opalescent in lustre; hind 

 tarsi three-fourths as long as the tibiae. Length (cf 9 ) 2.25-2.75 

 mm.; width 0.8-1.0 mm. Rhode Island (Boston Neck). A single 

 pair expertus n. sp. 



3- Form more slender than in hydropicus and still smaller in size, shining, 

 piceous-black, the prothorax less black to obscure testaceous, the 

 elytral suture also sometimes finely testaceous; legs pale; head two- 

 thirds as wide as the prothorax, with moderate though prominent 

 eyes, which are but little longer than the neck; antennae slender, not 

 quite as long as the elytra, fuscous, paler basally; prothorax widest 

 near apical third, where the sides are strongly rounded, thence con- 

 verging and straight to the obtuse but rather clearly defined and 

 scarcely at all blunt basal angles; base barely narrower than the 

 feebly sinuate apex; surface impressed and punctate near the hind 

 angles, with distinct and subenure stria; elytra nearly one-half 

 longer than wide, subparallel, barely at all inflated posteriorly, 

 about a third wider than the prothorax, obtuse at apex, the striae 

 fine impressed, the scutellar rather well developed; intervals feebly 

 convex, not in the least opalescent. Length (cf 9 ) 2.3-2.5 mm.;
