BEMBIDIINJE 195 



distinctly wider behind the middle than at base, the sides broadly 

 arcuate, the humeri moderately rounded; pedicel three-sevenths the 

 basal width; first stria strong and deep, the second feeble, the others 

 virtually obsolete, the second reappearing at apex; anterior fovea 

 strong, at two-fifths. Length 2.2 mm. ; width 0.8 mm. New Jersey. 



oblitus n. sp. 



Color piceous-black, the head and prothorax dark rufous 5 



5 Body rather convex and strongly shining; form somewhat as in the 

 preceding, but with relatively smaller head and prothorax; under 

 surface blackish, the legs pale flavate; head small, more than two- 

 thirds as wide as the prothorax, the eyes moderate in size, not prom- 

 inent; sulci converging; antennae piceous, the basal joint rufous, 

 scarcely at all shorter than the elytra, the medial joints a little 

 more than twice as long as wide, the second as in the preceding; 

 prothorax relatively small, barely two-thirds wider than long, 

 throughout almost as in oblitus, except that the feebly oblique sides 

 posteriorly are not visibly sinuate, and that the anterior transverse 

 impression is subobsolete; elytra relatively smaller, oval, one-half 

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

 ogival in nearly apical half, much wider behind the middle than at 

 base, the humeri more broadly rounded than in oblitus, the striation 

 similar, except that the first and second striae are even more abbre- 

 viated at base. Length 1.8-2.1 mm.; width 0.7-0.88 mm. New> 



York (near the city). Four examples cuneatus n. sp. 



A Similar to cuneatus in general characters, except that the head and 

 prothorax are relatively larger, the thoracic angles more reflexed; 

 elytra barely over two-fifths wider than the prothorax, similar 

 in general form but with the humeri more sharply rounded, and 

 excepting that three or four striae are more or less visible. Length 

 2.2 mm.; width 0.82 mm. North Carolina (Asheville). 



appalachius n. subsp. 



Body slightly less convex and not so shining, the elytra less deep in color; 

 under surface piceous, the legs flavate; head relatively even smaller 

 than in cuneatus, barely two-thirds as wide as the prothorax, the 

 eyes rather well developed, the sulci short and deep; antennae pice- 

 ous, with pale basal joint, three-fourths as long as the elytra, the 

 medial joints twice as long as wide, the second much more conspicu- 

 ously longer and thicker than the third than in cuneatus; prothorax 

 much shorter, one-half wider than long, as wide at base as at apex, 

 the moderately rounded sides becoming oblique and straight pos- 

 teriorly, the angles very obtuse, not prominent; surface nearly as 

 in the preceding species; elytra relatively larger, less oval, though a 

 little wider behind the middle than at base, one-half longer than 

 wide, nearly one-half wider than the prothorax, ogival in apical two- 

 fifths; humeri moderately rounded; pedicel scarcely more than two- 

 fifths as wide as the base; four striae on each elytron are distinct, the 

 sutural the deepest; anterior fovea but little before the middle. 

 Length 2.1-2.15 mm.; width 0.75 mm. Iowa (Cedar Rapids),
