No. 3.] LE CONTE ON EOCKY MOUNTAIN COLEOPTERA. 509 



truncate at base, and nearly so at apex; front angles not prominent, 

 sides moderately rounded, oblique, and not sinuate behind ; liind angles 

 slightly obtuse, not rounded, finely carinate; dorsal line entire, trans- 

 verse impressions deep, basal impressions square, deep. Elytra with 

 strife entire, finely punctured to beyond the middle ; outer ones feebly 

 impressed ; dorsal punctures 2, connected with the third stria. Length, 



Garland, Colo., one specimen. A peculiar and easily recognized 

 species, resembling a small Bradycellus. 



Bembidium acutiprons. — Black. Head with deep frontal impressions 

 converging at apex. Prothorax wider in front than long; sides slightly 

 rounded, strongly narrowed, and subsinuate behind ; hind angles rect- 

 angular, carinated, dorsal line strong, posterior transverse impression 

 and basal impressions deep. Elytra with 7 punctured strite, outer ones 

 gradually shorter and weaker; dorsal punctures upon the third inter- 

 space. Length, 3"™. 



Alamosa, Colo., one specimen. Allied to anguliferum and connivens, 

 but the sides of the prothorax are much less sinuate near the base, the 

 hind angles less prominent, and the legs and elytra are entirely black. 



Bembidium pr^cinctum. — Black shining, elytra finely alutaceous. 

 Head with long oblique impressions, converging but not meeting in 

 front. Prothorax transverse, strongly margined on the sides, much, 

 narrower and constricted at base, hind angles small, rectangular, cari- 

 nate, basal impressions deep, transverse impressions deep, the hind one 

 with a row of punctures, dorsal line fine. Elytra elongate-oval with 

 extremely fine, almost obliterated strise of small punctures, marginal 

 stria and groove deep, entire, marginal punctures few, dorsal punctures 

 2, small, connected with the 3rd stria. Length, 3'"'". 



Alamosa, Colo., one specimen. Allied to B. 4c-maculatum, but is en- 

 tirely black. 



A faunal memoir on the Coleoptera of California has been delayed for 

 more material, and this seems therefore a favorable opportunity for 

 making known the following remarkable species from that region. 



Bembidium TianiNUM. — Testaceous, occiput, middle of apex and 

 base of prothorax and cloud-like spots on elytra dusky. Depressed ; 

 frontal impressions broad, deep, parallel. Prothorax wider than long, 

 widest at middle, scarcely emarginate at apex, nearly truncate at base, 

 sides moderately rounded and strongly margined, base a little narrower 

 than apex, angles slightly obtuse not rounded, and not carinate ; dorsal 

 line fine, posterior transverse impression deep, feebly punctulate, basal 

 impressions broad, shallow. Elytra with entire deep impunctured 

 striae, somewhat less impressed behind and at the sides; dorsal punc- 

 tures 2, large, situated near the 2nd stria; the dusky markings are 

 connected near the suture as far as the 4th stria, and consist of three
