BEMBIDIIN^E 199 



15 Prothorax pale testaceous, similar in color to the ground of the ely- 

 tra, the head dusky 16 



Prothorax less abbreviated, darker, pale piceous, intermediate in color 

 between the nearly black head and the flavo-testaceous ground of 

 the elytra I? 



1 6 Frontal sulci deep anteriorly and there separated by barely more than 

 a third the maximum interocular width; eyes rather small and only 

 moderately prominent. Body oblong-suboval, moderately convex, 

 shining, the elytra but feebly sericeous; color testaceous, the broad 

 submedian blackish fascia very nubilous; under surface pale, the legs 

 flavate; head three-fourths as wide as the prothorax; antennae fla- 

 vate, as long as the elytra, the second joint very much longer than 

 the third; prothorax nearly one-half wider than long, the sides an- 

 teriorly strongly rounded, oblique and nearly straight posteriorly, 

 ihe obtuse angles with prominent apex, thickened by the rather 

 large setigerous pore; subbasal impression deep, angulate, the me- 

 dian stria distinct; elytra slightly more than one-half longer than 

 wide, not quite one-half wider than the prothorax, parallel, with 

 distinctly arcuate sides; first three striae more or less distinct, the 

 fourth and fifth feebly glimpsible; anterior fovea near two-fifths, 

 the posterior near apical sixth. Length 2.35-2.65 mm.; width 0.8- 

 0.95 mm. District of Columbia and North Carolina (Asheville). 

 Pennsylvania LeConte scitulus Lee. 



Frontal sulci shallow and more widely separated, more strongly micro- 

 reticulate than the rest of the surface; eyes much larger, conspicu- 

 ously prominent. Body rather more broadly oblong, very moder- 

 ately convex, shining, the elytra feebly sericeous; color pale testa- 

 ceous, the submedian fuscous fascia narrower, more feeble and still 

 more indefinite than in scitulus; under surface and legs very pale; 

 head fully three-fourths as wide as the prothorax; antennae long, slen- 

 der, pale flavo-testaceous, even somewhat longer than the elytra, 

 the second joint distinctly longer than the third; prothorax fully 

 one-half wider than long, formed as in scitulus, except that the pos- 

 teriorly oblique sides become slightly sinuate for a short distance 

 before the obtuse and reflexed angles, which are less prominent or 

 thickened at apex, the setigerous pore smaller; margins very dis- 

 tinctly reflexed; subbasal impression moderately deep, angulate, the 

 anterior obsolete as in scitulus, the stria distinct; elytra oblong, one- 

 half longer than wide, one-half wider than the prothorax, gradually 

 parabolic in apical two-fifths; sides feebly arcuate, the humeri 

 strongly rounded ; striation and foveae nearly as in scitulus. Length 

 2.55-2.65 mm.; width 0.9-1.0 mm. Iowa (Keokuk) and Mississippi 

 (Vicksburg) pallescens n. sp. 



Frontal sulci as in ^pallescens, though slightly deeper, widely separated, 

 the eyes similarly prominent but not quite so large. Body slightly 

 shorter, oblong, moderately convex, similar in color and lustre, ex- 

 cept that the head is only very slightly fuscous across the vertex 

 and the submedial elytral fasciform cloud still fainter and more in- 

 definite, sometimes barely traceable; antennae flavate, not quite so 

 long, though as long as the elytra; head proportionally as in palles-
