302 Memoirs on the Coleoptera 



wider than the prothorax, the grooves coarse, rather deep, with small and 

 well spaced punctures along the bottom, nowhere crenulate; intervals 

 flat, generally a little wider than the grooves, each with a single series, 

 generally scarcely impressed, of distinct punctures about half as wide as 

 the intervals, each bearing a very small silvery seta; femora finely, 

 sparsely punctate; abdomen strongly, rather closely punctate, the basal 

 segment in the male with a longitudinal and broadly impressed line 

 throughout the length, usually more acutely defined along the bottom. 

 Length (cf 9) 4-7-5-8 mm.; width 2.2-2.65 mm. Montana (Gallatin 

 Valley). Six specimens. 



Related to transversa but narrower and more elongate, with 

 relatively smaller and shorter prothorax, only about half as long 

 as the elytra and not three-fifths as in transversa. The prothorax is 

 however larger and much less coarsely punctured than in striata Say. 



Baris coloradensis n. sp. — A little smaller than montanica and rather 

 stouter, though less so than in transversa; prothorax a little larger and 

 less abbreviated than in montanica, but less developed than in transversa, 

 being four-sevenths as long as the elytra; color deep black, more polished 

 than in either of the species mentioned; beak more densely punctured 

 than in montanica, less arcuate, about similarly elongated; prothorax a 

 fourth wider than long, the sides feebly converging and more arcuate 

 than in the preceding, gradually still a little more arcuate anteriorly to 

 the apical constriction, which is very short; punctures not quite so 

 coarse as in montanica and less close-set, frequently separated by nearly 

 their diameters, the median impunctate line distinct but not entire; 

 scutellum impressed, slightly transverse; elytra two-fifths longer than 

 wide, only a fifth or sixth wider than the prothorax, the grooves deep, 

 finely, remotely punctate along the bottom, the intervals distinctly 

 wider than the grooves, with a subunimpressed series of punctures about 

 half as wide as the intervals, each bearing a small pale shining seta; 

 femora finely, loosely punctate; abdomen coarsely, closely punctate, the 

 first segment of the male broadly and feebly impressed along the middle, 

 not quite to the apex, the bottom of the impression not at all acutely 

 defined. Length (cf 9) 4.3-5.3 mm.; width 2.0-2.35 ^^- Colorado. 

 Two examples. 



This species is allied to montanica but is rather smaller and still 

 narrower, with relatively larger and less abbreviated, somewhat 

 more coarsely and loosely punctured prothorax, more shining 

 surface and more densely and coarsely cribrate abdomen. 



Baris subparilis n. sp. — Form shorter and stouter than in either of 

 the preceding, somewhat as in transversa, but with narrower though 

 similarly long prothorax, black, rather shining, strongly convex; beak 

 fully three-fourths as long as the prothorax, evidently arcuate, not 

 densely punctate, having bristling hairs beneath; prothorax a fourth or 

 fifth wider than long, distinctly narrower than the elytra, the sides
