HARPALIN.E 205 



the two preceding, the surface laterally only feebly convex, the 

 marginal gutter rather coarse, deep and even throughout the length, 

 the stria distinct and subenttre; elytra fully one-half longer than 

 wide and a fourth wider than the prothorax, parallel, with feebly 

 arcuate sides and obtuse apex, the sinus short and rather deep, 

 rendered very distinct by the obtuse prominence limiting it anteriorly ; 

 surface glabrous throughout, rather finely but very deeply striate, 

 the sutural stria long and deep; intervals strongly convex, the discal 

 puncture strong and deep, at three-fifths; abdomen with but few 

 fine punctures medially; hind tarsi stout, feebly tapering, the basal 

 joint unusually thick (9), much shorter than the fifth. Length 

 (cT 9 ) 10.2-12.0 mm.; width 4.0-4.6 mm. Pennsylvania to Wiscon- 

 sin and Missouri. Abundant discoideus Dej. 



Body much smaller though otherwise nearly similar, except that the pale 

 lateral part of the pronotum is limited to the diaphanous reflexed 

 margin and the cloud-like darker area of the elytra broader and 

 not approaching the base, sometimes extremely faint and nubilous; 

 lustre shining (cf) or with the elytra subalutaceous (9); head 

 nearly as in the preceding, except that the eyes are less prominent, 

 the fovese rather more elongate and outwardly arcuate and the 

 antennae fusco-testaceous, with two basal joints paler; prothorax as 

 in discoideus throughout, except that there are numerous wavy 

 transverse rugulae, the basal punctures finer, the apical even more 

 obsolete, the latero-basal surface more convex and the basal angles 

 not quite so sharply marked and not at all prominent; elytra two- 

 fifths longer than wide, about a fifth wider than the prothorax, the 

 parallel sides evidently arcuate, the apex obtuse, the sinus only very 

 feeble though evident; striae fine, feebly impressed, the intervals 

 feebly convex, with a few very minute hairs apically, the puncture 

 similarly at three-fifths; abdomen with few basal and subbasal 

 punctules medially; hind tarsi nearly as in discoideus. Length (c? 9 ) 

 8.8-10.0 mm.; width 3.4-3.9 mm. Rhode Island to Iowa. [A. 

 sanctcccnicis Fabr.?] baltimorensis Say 



5 Punctures of the alternate intervals confined to the apical part of 

 the elytra; form nearly as in the preceding but rather more convex, 

 dark in color, the upper surface with metallic lustre varying from 

 violaceous to greenish, the under surface and legs piceous; prothorax 

 nearly as in baltimorensis but less transverse, more convex and with 

 the basal regions less punctured; elytra also similar in general form 

 but more parallel, the striae fine; intervals flat, 246 distinctly 

 punctured at apex. Length 8.5-9.5 mm. Colorado to California 

 and Oregon. Apparently not common pitychrous Lee. 



Punctures of the alternate intervals extending with equal density and 

 distinctness from apex to base; body elongate-suboval, strongly 

 convex, shining, the elytra ( 9 ) but very feebly alutaceous, deep 

 black throughout, the elytra generally with feeble greenish or 

 greenish-brassy lustre; head rather more than two-thirds as wide 

 as the prothorax, with only moderately prominent eyes and rather 

 fine, outwardly arcuate foveae, the surface smooth though with 

 numerous punctures broadly toward the posterior part of the eyes
