arcuate, closely but not densely punctate and very nearly as long as the 

 prothorax, the latter between a fourth and third wider than long, the 

 sides parallel and very feebly arcuate, gradually evenly rounding in 

 about apical third; punctures somewhat coarse, separated by half their 

 diameters or less, coarser and densely rugulose at the sides, the median 

 smooth line very narrow, visible in basal half, the lobe moderate; scutel- 

 lum small, rounded, feebly punctulate; elytra not quite one-half longer 

 than wide, very little wider than the prothorax and almost twice as long, 

 the sides very feebly arcuate, gradually more so behind, the apex obtusely 

 rounded; humeral callus moderate; grooves deep, not very coarse, the 

 intervals twice as wide, each with a single series of small, well separated 

 punctures, the second and third distinctly wider; abdomen with moder- 

 ate, shallow and well separated punctures, scarcely closer at the sides. 

 Length (cT 9) 3-I-3-3 mm.; width 1.15-1.28 mm. New Mexico, — 

 F. H. Snow. 



The specimen supposed to be the male, because of somewhat 

 shorter and more slender beak, has the thoracic punctures slightly 

 less coarse; there do not seem to be any distinct abdominal modi- 

 fications. 



The next three species here described are stouter and less cyllndrlc 

 than those immediately preceding and do not belong in their 

 vicinity, but they would also be inharmonious elsewhere in the 

 genus; they are all from the vicinity of Greeley, Colorado. 



Baris meraca n. sp. — Oblong-suboval, convex, not very shining, black, 

 the legs slightly piceous; beak in the female rather thick, feebly arcuate, 

 finely and densely, subrugosely punctate and three-fifths as long as the 

 prothorax, the latter nearly a third wider than long, the sides feebly 

 converging and but slightly arcuate, gradually rounding and oblique in 

 about apical third; punctures moderately coarse, deep and close-set, the 

 median smooth line obsolete; basal lobe very moderate, the scutellum 

 small, rounded and punctulate; elytra barely at all wider than the pro- 

 thorax and three-fourths longer, a third longer than wide, the parallel 

 sides nearly straight, gradually rounding in about apical third, the 

 humeri slightly prominent; grooves deep, not very coarse, the intervals, 

 about twice as wide as the grooves, each with a series of rather coarse, 

 close and almost transversely crowded punctures, the second and third 

 a little wider, with more rounded punctures; setae rather small but very 

 distinct; abdomen with moderate, somewhat shallow but close punctures. 

 Length (9) 3-2 mm.; width 1.3 mm. Colorado (Greeley), — Wickham. 



A very distinct species not at all near any previously described, 

 having notably close elytral sculpture and very densely sculptured 

 beak; the tibiae are not at all denticulate externally at apex. 



Baris probata n. sp. — -Larger and much stouter than meraca, convex, 

 black, not very shining, the legs but faintly picescent, the femora more
