HARPALIN.E 139 



tin us but with the angles scarcely at all rounded and nearly right, 

 barely three-fourths as wide as the base, which is transverse and 

 only very finely margined, the angles slightly obtuse and broadly 

 rounded; surface very smooth, with vitreous lustre and only feebly 

 convex, completely impunctate, excepting a few excessively minute 

 punctules at the lateral margin and scattered sparsely over the 

 broad and extremely shallow foveae; stria very fine, only visible in 

 median half of the length; elytra very nearly one-half longer than 

 wide, not very obviously wider than the prothorax, parallel, with 

 feebly arcuate sides and obtusely ogival apex, the sinus wide and 

 very feeble; striae fine, the scutellar distinct, the series having 

 numerous punctures about twelve on the fifth stria, the intervals 

 not quite flat and narrow but not very strongly convex on the de- 

 clivity; hind tarsi very slender. Length (9) 7.0 mm.; width 2.9 

 mm. Mexico (Durango City), Wickham. Evidently allied to 

 semirufus Bates, but differing in the subimpunctate pronotum and 

 very shining elytra *dichromatus n. sp. 



8 Sides of the prothorax sinuate posteriorly, the angles right and very 

 acutely defined, not in the least blunt. Body subdepressed, oblong, 

 shining, deep black, the thoracic margins not at all paler, the elytra 

 polished and with feeble opalescence; tinder suiface blackish-piceous, 

 the legs, antennae and trophi testaceous; head large, four-fifths as 

 wide as the prothorax, with very prominent and rather large eyes 

 and very minute punctiform foveae, the antennae slender and rather 

 long; prothorax one-half wider than long, the sides rounded anter- 

 iorly, oblique posteriorly, very finely reflexed throughout; apex 

 broadly, evenly and feebly sinuate, with narrowly rounded but 

 scarcely advanced angles and barely visibly narrower than the base, 

 which is transverse medially, feebly arcuate laterally; surface feebly 

 convex, the latero-basal region scarcely at all flattened, finely, rather 

 closely punctate, the foveae moderate and very feebly impressed, 

 the stria very fine; elytra parallel, with but very feebly arcuate sides 

 and obtuse apex, two-fifths longer than wide and nearly a fourth 

 wider than the prothorax, the sinus extremely feeble; surface smooth, 

 polished and punctureless, except the apical slope which is punctulate 

 and minutely pubescent; striae fine, the scutellar moderate, scarcely 

 at all oblique, the series distinct, each with about six small punctures; 

 intervals virtually flat; abdomen very minutely and sparsely punctu- 

 late and minutely pubescent almost throughout; hind tarsi long and 

 very slender. Length ( 9 ) 5-4 mm.; width 2.0 mm. Texas (Browns- 

 ville) , Snow angulatus n. sp. 



Sides of the prothorax oblique but not sinuate posteriorly, the hind angles 

 obtuse 9 



9 Form oblong, depressed, shining, black, the thoracic side margins 

 not paler, the under surface red-brown, the legs and long slender 

 antennae pale testaceous; elytra with feeble opalescence; head large 

 and rather short, more than three-fourths as wide as the prothorax, 

 the eyes large and convex, less prominent in the female; foveae ex- 

 cessively minute; prothorax very transverse, two-thirds wider than 

 long, the sides strongly rounded anteriorly, oblique and virtually
