BEMBIDIIN^E 183 



with an even row of small punctures, interrupted at the middle, 

 where the single larger puncture is distinct; foveae small, distant 

 from the angles; elytra less than one-half longer than wide, only a 

 little more than a fourth wider than the prothorax, evenly ogival 

 in posterior two-fifths, deep sutural stria obsolete in basal eighth, 

 the second very fine line sometimes visible; foveae near two-fifths 

 and just behind the middle. Length 1.8-2.1 mm.; width 0.7-0.85 

 mm. Missouri (St. Louis), North Carolina (Asheville), New York 

 and Rhode Island. An attached note by Jiilich says that the spe- 

 cies was found in large numbers with ants in February. . . laetifica n. sp. 



Body rather narrow, elongate-suboval, convex, shining, deep black, each 

 elytron with the humerus very indefinitely and feebly pallid and 

 with a subexternal area near apical third, which is feebly and very 

 indefinitely pale; legs rufous; head barely more than half as wide as 

 the prothorax, the anterior strides distinct; eyes moderate in size, 

 peculiar in being almost flat; antennae short, infuscate distally, but 

 little more than half as long as the elytra; prothorax nearly one-half 

 wider than long, widest at anterior two-fifths, the sides there mod- 

 erately rounded, oblique and nearly straight in fully basal half; 

 subbasal sulcus with a regular line of very close-set small punctures, 

 the larger medial puncture distinct; foveae rather larger and deeper 

 than usual, remote from the angles; elytra more than one-half longer 

 than wide, gradually acutely ogival in fully apical two-fifths, only 

 about a fourth wider than the prothorax; deep sutural stria attain- 

 ing the base or virtually so, the second line rather distinct in most 

 examples; foveae at two and four sevenths. Length 1.85-2.1 mm.; 

 width 0.65-0.75 mm. Nevada (Reno) and California (Humboldt 

 Co.). Many specimens renoica n. sp. 



Body narrowly oval, convex, polished, deep black, the elytra without 

 paler areas; under surface and legs obscure rufous; head relatively 

 larger, three-fifths as wide as the prothorax, the anterior strioles 

 distinct, oblique; eyes moderate and slightly convex but not prom- 

 inent; antennae fuscous, thick, slender and pale basally, three-fifths 

 as long as the elytra; prothorax scarcely two-fifths wider than long, 

 parallel, widest at the middle, the sides very evenly and moderately 

 arcuate from apex to base, the latter wider than the apex, which is 

 truncate, with the obtuse angles unusually pronounced; subbasal 

 sulcus with small close-set punctures, the series rather widely inter- 

 rupted medially, the medial puncture large and strong; foveae mod- 

 erate, deep, the carina at the angles short but unusually distinct; 

 elytra one-half longer than wide, fully two-fifths wider than the pro- 

 thorax, very evenly oval, arcuately rounding in nearly apical half; 

 deep sutural stria slightly abbreviated at base; there is no distinct 

 second line; foveae small, near basal and apical third. Length 1.9 

 mm.; width 0.75 mm. California (Lake Tahoe). One specimen. 



tahoensis n. sp. 



14 Body pale flavo-testaceous throughout and elongate, the habitus 

 much as in dolosa. Polished, rather convex; head fully three-fifths 

 as wide as the prothorax, the anterior strioles feeble, oblique; eyes 

 rather large and convex; antennae two-thirds as long as the elytra,
