HARPALIN.E i6i 



deep black above and beneath, without trace of metallic lustre at 

 any part, the legs rufo-piceous, the antennae ferruginous; head well 

 developed, two-thirds as wide as the prothorax with unusually 

 prominent eyes; prothorax more transverse than usual in this section, 

 fully two-fifths wider than long, evenly and rather strongly rounded 

 at the sides, the marginal groove fine; base broadly, feebly sinuate 

 medially; surface gradually declivo-explanate toward the hind angles, 

 the fovese punctiform, impressed and near basal fourth, impunctate; 

 elytra not distinctly wider than the prothorax, obtuse at apex, the 

 apices oblique and subrectilinear; scutellar stria long; punctures of 

 the three series strong and conspicuous but abrupt and not impressed; 

 intervals flat, becoming narrow and convex on the apical slope as 

 usual; middle tibiae (of) but feebly arcuate though distinctly granulo- 

 serrate within, the tarsi as usual. Length (cf) 9.0 mm.; width 

 3.3 mm. Arizona (probably southern) symbolicus n. sp. 



Elytral striae stronger and more impressed, the eighth notably coarse and 

 deep throughout, the marginal interval with more or less evident 

 fine confused punctures throughout, though becoming obsolescent 

 or sparser along the interval of interruption of the series of foveae. n 



IT Punctures of the marginal interval equally distinct in the interval of 

 interruption of the foveae but sparser than basally or apically, the 

 short stiff hairs borne by these punctures more distinct and more 

 broadly so at apex than in any other species. Body oblong-elongate, 

 moderately convex, shining, black, the upper surface sometimes 

 with feeble viridi-aeneous lustre, especially in the female, the under 

 surface, legs and labrum dark red-brown; palpi and antennae paler; 

 head nearly three-fourths as wide as the prothorax, the eyes promi- 

 nent; prothorax two-fifths wider than long, parallel, the sides very 

 moderately and subevenly rounded, the base feebly arcuate, scarcely 

 traceably bisinuate; marginal gutter at the sides rather strong; 

 surface feebly subexplanate toward the basal angles, more strongly 

 in the male, with a few feeble punctures near the base, the foveae 

 subpunctiform, small, feeble and near basal sixth; elytra just visibly 

 wider than the prothorax, the apical sinus almost obsolete, the 

 punctures of the three series small but distinct; middle tibiae (c?) 

 strongly arcuate and with strong internal granulo-serration. Length 

 (cf 9 ) 8.5-9.5 mm. ; width 3.0-3.3 mm. Texas (locality unrecorded). 



aequalis n. sp. 



Punctures of the marginal interval barely at all traceable in the medial 

 interruption of the line of foveae, distinct basally and apically, ex- 

 tending to adacent intervals in the latter case; surface more strongly 

 convex than in either of the two preceding, the form more cylindric, 

 the elytral striae coarser and still more deeply impressed than in 

 cequalis 12 



12 Form subcylindric, shining, black, the upper surface with strong 

 greenish metallic lustre, especially on the elytra; under surface 

 nearly black, the legs and epipleura obscure rufous; antennae, 

 labrum and palpi paler; head rather more than two-thirds as wide 

 as the prothorax, with rather large and prominent eyes; prothorax
