Bembidium nevadense Ulke. 



Placer Co., Cal. Through C. V. Riley, 1888. 2 specimens. 



This species is recorded from Reno, Nevada, by Casey and from 

 Cal. and Or. by Hayward. 



Bembidium consanguineum Hayw. 



Or. I specimen. 



This species is recorded from New Mexico, Colorado (Boulder 

 Co.), Utah (Southwestern), Arizona (Tucson and other parts) by 

 Casey, and from Cal., Utah, Ariz., Col., Guadaloupe Isd. by Hayward. 



Bembidium micans new species. 



Form oblong, parallel, moderately convex; color black, very shining, head 

 and thorax very faintly aeneous, an indistinct spot on the humerus and a sub- 

 marginal one at apical two fifths dull testaceous. Head as wide as the thorax 

 at apex ; eyes large ; frontal sulci single, straight, parallel, not deep ; antennae 

 reaching the basal third of the elytra. Thorax obtrapezoidal, one half wider 

 than long, base as wide as the apex, moderately convex, sides moderately 

 rounded in front, very slightly sinuate in front of the posterior angles which 

 are sub-rectangular ; margin rather broad, narrowly reflexed at edge ; basal 

 foveas strong, bistriate, rugose, carinas long and sharply defined ; anterior im- 

 pression distinct ; median line strong, slightly impressed, abbreviated in front 

 and behind. Elytra one half wider than the thorax, parallel, three fifths longer 

 than wide, strongly arcuate from apical third to the apex, humeri subangulate ; 

 striae very fine, abbreviated at apex, finely punctate on basal half, the seventh 

 obsolete, represented at base by a row of very indistinct punctures, eighth 

 very deep and indistinct from the margin ; two impressed punctures on the 

 third stria at basal one third and apical two fifths. Length, 5-5.5 mm.; width, 

 1.8—2 mm. 1 (J, 1 J,

In Col. Casey's recent revision of Bembidium (Mem. Col., VIII, 

 1918), this species would be placed with lugubre Lee, because of its 

 maculate elytra and trapezoidal thorax. It seems, however, most 

 closely related to nitens Lee. (grapei Gyll.), because of its highly pol- 

 ished integuments and finely punctured and indistinct striae. In Mr. 

 Hayward's arrangement of the genus, it would be placed near breve 

 Mots., from which it differs by its maculate elytra. 



Bembidium dilaticolle new species. 



Form rather broad, sub-depressed. Color black, head and thorax slightly 

 greenish metallic, elytra pale testaceous, the suture and a transverse fascia 

 behind the middle blackish piceous ; palpi, antennae and legs pale rufo-testa-
