HARPALIISLE 107 



more parallel, fully one-half wider than long, the sides anteriorly 

 feebly arcuate, nearly straight posteriorly; apical sinus moderate, 

 much narrower than the base, the apical angles very broadly, the 

 basal very narrowly, rounded; surface almost evenly and very steeply 

 sloping at the sides to the fine marginal bead throughout; basal 

 regions more or less punctulate, rugulose or alutaceous throughout 

 the width, but more shining, convex and obsoletely punctulate 

 between the deep and broadly lineiform, densely rugose fovese and 

 the sides; base very obsoletely bisinuate but transverse; elytra one- 

 half (d 71 ) to two-fifths (9) longer than wide, scarcely visibly or 

 evidently wider than the prothorax respectively, obtuse at apex, the 

 parallel sides broadly arcuate; sinus very feeble though evident; 

 striae fine, not deep, the intervals very feebly convex (cf) to per- 

 fectly flat ( 9 ), the puncture near apical third or fourth respectively; 

 basal joint of the hind tarsi evidently shorter than the fifth. Length 

 (cf 9 ) 9.0-10.0 mm.; width 3.4-4.0 mm. Female much stouter 

 than the male. Nevada (Reno). Four examples. . .peritus n. sp. 



Body narrowly oblong, moderately convex, polished throughout (d 71 ), 

 deep black above and beneath, the epipleura sometimes picescent; 

 legs black, the anterior and middle tarsi of the male slightly piceous; 

 head fully three-fifths as wide as the prothorax, the eyes very 

 prominent; antennae slender, testaceous, the basal joints blackish, 

 except the first two, which are testaceous; foveae small, circular, very 

 deep, abrupt and perforate; prothorax distinctly less than one-half 

 wider than long, the sides rounded anteriorly, slightly convergent 

 and nearly straight thence to the basal angles, which are but little 

 more than right though rounded; base transverse, wider than the 

 distinctly sinuate apex, the apical angles rather broadly rounded; 

 surface somewhat feebly convex, abruptly and very steeply sloping, 

 though rather shallow, at the sides, with the fine bead almost but not 

 quite even and equal throughout the length; foveae sublinear but 

 broadly impressed and moderately deep, finely, not densely punctured, 

 the lateral convex surface generally impunctate, though sometimes 

 finely punctured throughout; transverse impressions wanting, the 

 stria extremely fine and feeble; elytra nearly one-half longer than 

 wide to less, but very little wider than the prothorax, obtuse at 

 apex, the parallel sides feebly arcuate; sinus scarcely traceable, 

 obsolete; striae rather fine, feebly impressed, the scutellar long, the 

 intervals feebly convex, the puncture at apical fourth; basal joint 

 of the hind tarsi shorter than the fifth. Length (cf) 8.2-9.0 mm.; 

 width 3.1-3.25 mm. Oregon (Clackamas Co.) . . . .celax n. sp. 



34 Form oblong-suboval, convex, shining, brilliant green above, the 

 intervals 135 f the elytra more or less aeneous; under surface 

 black, subalutaceous, the epipleura and legs dusky testaceous; 

 antennae slender, black, the first three joints pallid; palpi rather 

 short, testaceous; head nearly two-thirds as wide as the prothorax, 

 the eyes unusually large and prominent; foveae rather large, deep, 

 irregular, with a fine branch curving outward slightly; mandibles 

 short, dark rufous, black at tip; prothorax two-fifths wider than 

 long, the sides broadly and subevenly arcuate, gradually more
