BEMBIDIINyE 71 



not closely punctate, the striae and punctures gradually obsolete 

 before the tip; foveae near two-fifths and two-thirds, rather coarse. 

 Length (cf 9 ) 4.1-4.5 mm.; width 1.35-1.6 mm. Canada (three 

 examples taken by the writer at Ottawa), New York (Lake Cham- 

 plain), Wisconsin (Bay field), and New Mexico (Las Vegas). [Och- 



thedromus gelidns Lee.] scopulinum Kirby 



A Similar to scopulinum but with the head relatively not so large, 

 the prothorax notably larger and broader, being a fourth wider 

 than long, the elytra paler castaneous, not so elongate, oblong, 

 parallel, not inflated behind, with the striae more coarsely punc- 

 tate and entire, the row of punctures constituting the seventh 

 stria entire and strongly marked throughout, the legs more 

 slender and wholly testaceous, these characters applying strictly 

 only to the female type from Las Vegas, New Mexico, and 4.5 

 by 1.7 mm. in dimensions. Three other specimens from " N. M." 

 and from Sta. Fe Canon, N. M., the latter taken by Prof. Snow, 

 are more like typical scopulinum, but larger, slightly stouter and 

 with relatively larger and broader prothorax and smaller head, 

 the striae similarly slightly abbreviated, the punctures of the 

 seventh gradually fine and disappearing posteriorly, and the ely- 

 tra longer, feebly inflated behind and less coarsely punctate, the 

 legs pale testaceous throughout, as they are also in the Lake Su- 

 perior examples; they are 4.2-4.3 by 1.65 mm. in dimensions. 



bellulum n. subsp. 



Head relatively less developed, always distinctly narrower than an ely- 

 tron 49 



49 Body small in size, rather depressed, with short transverse pro- 

 thorax, which is apparently somewhat wider at base than at apex. 

 Body deep black, with greenish lustre, the elytra not quite so black, 

 the posterior pale spot clearly defined and feebly oblique; legs rufo- 

 piceous, the femora black, with paler tip; head four-fifths as wide 

 as the prothorax, with prominent eyes; antennae black, with piceous 

 basal joint, three-fourths as long as the elytra, the medial joints 

 not quite three times as long as wide; prothorax one-half wider than 

 long, the well rounded sides gradually becoming parallel in nearly 

 basal fifth, the angles right; surface with very feeble impressions 

 and distinct subentire stria, the foveae large, impressed, linearly 

 deep at the bottom, the carina rather long and strong; elytra par- 

 allel, with but very feebly arcuate sides and rapidly rounded humeri, 

 parabolic in apical third, not quite one-half longer than wide and 

 about three-fifths wider than the prothorax; striae not coarse, wholly 

 unimpressed, gradually obsolescent near the apex, the punctures 

 rather small but deep and moderately separated, the seventh stria 

 a subentire series of extremely minute punctules; foveae near two- 

 fifths and two-thirds. Length (9 ) 4.5 mm.; width 1.75 mm. Cal- 

 ifornia (Truckee). One specimen satelles n. sp. 



Body much larger, more convex, the prothorax much narrower at base 



than at apex 50 



50 Form elongate, very convex, polished, black, with feeble greenish 

 lustre, the elytra sometimes aenescent, the posterior pale spot small,
