Barix.^ 341 



strongly and densely punctured than in the preceding; beak in the male 

 short, feebly arcuate, closely punctate and three-fifths as long as the 

 prothorax, the latter rather large, a fourth wider than long, the sides 

 feebly converging and slightly arcuate, somewhat rapidly rounding in 

 between apical third and fourth; punctures everywhere dense, somewhat 

 coarse laterally, notably fine medially, and without trace of impunctate 

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

 subquadrate not at all transverse; elytra not a third longer than wide, 

 slightly wider than the prothorax and barely three-fourths longer, the 

 sides nearly straight and parallel, parabolically rounding in about ajncal 

 third, the humeral callus feeble; grooves rather coarse and with strong 

 distant punctures along the bottom; intervals one-half wider than the 

 grooves, each with a single series of rather coarse but separated, rounded 

 punctures, the second and third wider, with finer, closer and more con- 

 fused series; setae moderate, pale and distinct; abdomen with moderately 

 coarse, close-set punctures, sparser within a feeble basal impression in the 

 male, broadly obsolescent in the basal part of the second segment. 

 Length (cf ) 3.8 mm.; width 1.65 mm. Colorado (Greeley), — Wickham. 



Differs from meraca in its larger size, much stouter form, more 

 finely and very closely punctate prothorax, more rapidly narrowed 

 at apex, in the coarser elytral grooves and relatively narrower 

 intervals, with looser series of circular and rather coarse punctures, 

 and in the closer abdominal punctures. 



Baris oviculata n. sp. — Narrower than the preceding but broader than 

 meraca, strongly convex, shining, black, the elytra and legs with feeble 

 piceous tinge; beak in the male short, cylindro-arcuate, closely punctu- 

 late and three-fifths as long as the prothorax, which is almost a third 

 wider than long, the sides very distinctly converging, feebly arcuate, 

 rounding rather rapidly in apical fourth, subsinuate in the apical ob- 

 liquity; punctures relatively coarse, separated by half their diameters, 

 dense laterally, the median smooth line evident except toward base and 

 apex; basal lobe small, the scutellum small, strongly transverse, not 

 impressed; elytra a third longer than wide, evidently wider than the 

 prothorax and four-fifths longer, the sides parallel, nearly straight, 

 gradually broadly rounding behind, the apex not obtuse; humeral callus 

 distinct; grooves moderately coarse and deep, the punctures not very 

 distinct; intervals twice as wide as the grooves, each with a single series 

 of very moderate, evidently though unevenly separated punctures, the 

 second and third wider, the latter with finer, closer and more confused 

 punctures; setas moderate, pale, glistening and distinct; abdomen rather 

 loosely, moderately and very shallowly punctate, the male with a bas^l 

 impression, which becomes gradually and narrowly, subcanalicularly 

 attenuate behind, extending to the apex of the second segment. Length 

 (c?') 3-35 mm.; width 1.4 mm. Colorado (Greeley), — Wickham. 



Distinguishable from probata by the narrower form, looser sculp- 

 ture and different male sexual characters, coarser pronotal punctures
