HARPALIN^E 191 



thorax differing from any of the preceding in being perfectly parallel 

 and straight at the sides, the latter rounding only at apex, one-half 

 wider than long, the apex deeply sinuate, with narrowly rounded 

 angles and nearly three-fourths as wide as the transverse base, the 

 basal angles absolutely right, very sharply defined, not at all blunt 

 though not prominent; surface convex, shining, subimpunctate except 

 on the narrowly deplanate sides and toward base, especially in the 

 large deep and rather rounded foveae, the stria fine; elytra two-fifths 

 longer than wide, a fourth wider than the prothorax, parallel, obtuse 

 at tip, the sinus broad and feeble but distinct; striae fine, deeper 

 suturo-basally, the intervals flat or nearly so, the scutellar stria 

 long, the puncture at three-fifths; surface without trace of any sort 

 of punctuation, except the marginal fovese; hind tarsi with the basal 

 joint as long as the next two and equal to the fifth. Length (cf 9 ) 

 9.0-10.0 mm.; width 3.8-4.4 mm. Northern California. Abundant.

22 Body small in size, oblong-oval, rather convex, shining above, with 

 greenish-bronze lustre, the elytra (9) sericeo-opaculate; under 

 surface and legs colored as in the preceding; head very small, less 

 than half as wide as the prothorax, smooth, with deep foveae curving 

 outwardly, the eyes prominent; antennae slendei, fuscous, the three 

 basal joints pale testaceous; prothorax two-fifths (cf ) to one-half 

 ( 9 ) wider than long, the sides evenly and moderately arcuate and 

 converging almost evenly from base to apex, the latter rather feebly 

 sinuate, with broadly rounded angles and only three-fifths as wide 

 as the base, which is transverse and finely margined, with the angles 

 right, their apices very finely blunt; surface finely reflexed anteriorly 

 at the sides, the margin gradually rather wide and flat posteriorly 

 and sparsely punctate, the fovese large, shallow, closely punctate, 

 the remainder of the basal parts very finely punctulate and the rest 

 of the disk wholly impunctate, though with numerous transverse 

 wavy rugulae; elytra rather less than one-half longer than wide, 

 oblong-oval, slightly wider than the prothorax, the sides evenly and 

 moderately rounded to the thoracic angles, without exposed humeri; 

 apex gradually obtuse, the sinus short, very feeble; striae fine, the 

 scutellar long; intervals flat or nearly so, the puncture distinct and at 

 three-fifths, the disk without trace of other punctuation except the 

 lateral foveae; hind tarsi slender, the basal joint longer than the 

 next two or the fifth. Length (cf 9 ) 7.8-8.5 mm.; width 3.3-3.7 

 mm. District of Columbia to Kansas. Abundant. [.4. siibccneus

Body narrower in outline than the preceding and rather more convex, 

 black, the upper surface with greenish or coppery-green metallic 

 lustre, the elytra (9 ) barely at all alutaceous, the *idc margins of 

 the pronotum diaphanously pale; under surface black, the epipleura 

 obscure, the legs paler, rufous; head relatively much larger than in 

 ccenus, with remarkably large and prominent eyes, three-fifths as 

 wide as the prothorax, the foveae moderate, sublinear, very deep; 

 antennae slender, blackish, with the two basal joints pale; prothorax 

 one-half wider than long to a little less, the sides very evenly and
