HARPALIN^; 125 



posteriorly, the angles right, sharp; base rectilinear, strongly 

 margined, a little wider than the apex, which is feebly sinuate, with 

 broadly rounded angles; surface very smooth, the re flexed sides very 

 fine and equal from apex to base, impunctate, joining the strong 

 marginal line of the base, the basal fovese small, elongate, rather 

 deep but impunctate, the median stria excessively fine; elytra short, 

 less than one-half longer than wide, oblong, not evidently wider than 

 the prothorax, very obtuse, the apex in posterior third conjointly 

 circularly rounded, the sinus completely wanting, the edge being 

 evenly arcuate; striae rather strong, deeply impressed only suturally, 

 the scutellar deep and joining the first, the lateral line of foveae 

 strong, not interrupted but widely spaced medially; surface with 

 a strong setigerous puncture at the second stria before apical fourth; 

 first three joints of the hind tarsi rapidly decreasing, the first much 

 shorter than the fifth. Length (cT) 7.5-8.2 mm.; width 3.4-3.7 mm. 

 Texas gravis Lee. 



Body oblong, strongly shining, much less convex than in gravis and deep 

 black in color above and beneath, without trace of metallic coloration, 

 the prosternum medially, trochanters, tibiae and tarsi obscure rufous, 

 the femora deep black; antennae slender, attaining the thoracic base, 

 the third and fourth joints partially blackish, the trophi testaceous; 

 head less abbreviated, the eyes moderately prominent, the foveae 

 perforato-punctiform; men turn absolutely edentate, the sinus recti- 

 linearly transverse at the bottom; prothorax one-half wider than 

 long, the sides rounded anteriorly, very feebly converging and straight 

 posteriorly to the angles, which are right and not rounded, the tips 

 barely at all blunt; apex rather strongly sinuate, with moderately 

 rounded angles, distinctly narrower than the transverse base; surface 

 rather abruptly declivous anteriorly to the very fine reflexed edge, 

 which expands but little posteriorly, finely punctulate and obsolete 

 before basal fourth, the lineate foveae deep, broadly impressed and 

 rather densely punctate, the punctures extending sparsely and finely 

 over the feebly convex area thence to the sides and internally almost 

 to the middle; stria very fine; elytra a litttle less than one-half 

 longer than wide, not evidently wider than the prothorax, very 

 obtuse at apex, the sinus represented by a straighter part of the 

 edge, the parallel sides feebly arcuate; striae fine, the intervals 

 almost flat, the puncture near apical fourth; hind tarsi as in gravis. 

 Length (cf ) 9.5 mm.; width 3.65 mm. California (Siskiyou Co.),

23 Form oblong, moderately convex, shining, the elytra ( 9 ) feebly 

 alutaceous; color dark castaneous above, the under surface, legs 

 and trophi pale reddish-brown; antennae slender, more than attaining 

 the thoracic base, dusky testaceous, the two basal joints paler and 

 honey-yellow; head much smaller than in the two preceding though 

 nearly three-fifths as wide as the prothorax, the eyes moderate, 

 prominent, the foveae minutely perforato-punctiform; mentum tooth 

 evident but very broad at base and narrowly rounded at tip; pro- 

 thorax one-half wider than long, much narrower than the elytra, 

 the apex moderately sinuate, with well rounded angles and scarcely
