HARPALIN.E 93 



the base and only very feebly sinuate; base transverse, the margin 

 interrupted medially, the angles but slightly obtuse though unusually 

 broadly rounded; surface convex, the reflexed margin fine anteriorly, 

 gradually becoming about three times as wide and rather abruptly 

 lost on the feebly convex surface in about basal third, the fovese 

 moderately deep, broadly impressed, strongly and closely punctate; 

 finer punctures are also sparsely scattered over the surface thence to 

 the sides; stria extremely fine and feeble; elytra not quite one-half 

 longer than wide, barely as wide as the prothorax, gradually rounding 

 and obtuse from slightly behind the middle, the oblique sinus rather 

 short and extremely feeble, the edge about straight; striae strong, 

 deeply impressed, the scutellar rather long and also deep, the in- 

 tervals (cf) distinctly convex, polished, without evident micro- 

 reticulation, the third with a distinct puncture attached to the second 

 stria near apical third; lateral line of foveae very widely spaced 

 medially but not interrupted; hind tarsi glabrous above, the first 

 joint distinctly shorter than the fifth. Length (cf) 9-6 mm.; 

 width 3.4 mm. New Jersey. [?H. viduus Lee., i. litt. ; Sm. Cont. 

 Kno., 1860, p. 3 a name subsequently given to an entirely different 

 species.] A female 10.0X3.8 mm. in dimensions, from Wisconsin, 

 is also placed here for the present; the head is a little larger, being 

 about two-thirds as wide as the prothorax, the latter less abbreviated 

 though still rather strongly transverse, similar, except that the 

 lateral gutter expands and curves inward more rapidly near basal 

 third, at the same time losing itself on the feeble latero-basal con- 

 vexity; the elytra are very shining though the minute sculpture is 

 somewhat evident, the sinus barely more than straight and the 

 basal joint of the hind tarsi is fully as long as the fifth in the female 

 of the preceding species the basal joint is generally relatively shorter 

 than in the male; the mentum tooth is obsolete in both, being simply 



a median arcuation recisus n. sp. 



7 Mentum distinctly and more or less strongly, often acutely toothed. 8 

 Mentum with an extremely short and generally broadly rounded tooth . 15 



Mentum edentate, usually without trace of tooth 22

Legs wholly or in great part ferruginous 13 



9 Elytral striae feebly crenulate. Form oblong-elongate, convex, 

 parallel, strongly shining, deep black throughout, even the anterior 

 and middle tarsi (c? ); head not quite three-fifths as wide as the pro- 

 thorax, the eyes moderate, the mandibles black, rufescent just before 

 the tip; antennae slender, the joints long, testaceous, gradually 

 infuscate basally, the basal joint pale; prothorax rather long, barely 

 two-fifths wider than long, the sides subevenly and very moderately 

 rounded, more converging anteriorly, the moderately sinuate apex 

 much narrower than the base, which is very feebly, angularly sinuate, 

 the fine margin feeble at the middle, the angles rather broadly 

 rounded; surface smooth, the very finely reflexed lateral margin 

 continuing unmodified to the base, the foveae rather deep, broadly 

 linear, rugosely punctate, the convex surface thence to the sides 

 impunctate, the stria extremely fine and feeble; elytra long, fully
