Barix.e 305 



the tarsi rufescent; beak more slender, feebly, evenly arcuate, not very 

 strongly or densely punctate, three-fourths as long as the prothorax in 

 the male; prothorax almost as long as wide, the broadly arcuate sides 

 becoming straighter and parallel in about basal half, the apical tubulation 

 obliterated; punctures somewhat coarse, deep, separated by half their 

 diameters, denser laterally, the smooth median line narrow though not 

 much abbreviated; elytra two-fifths longer than wide, two-thirds longer 

 and a fifth wider than the prothorax, the humeri prominent, the sides 

 behind them slightly converging; grooves coarse, deep, only a little 

 narrower than the intervals, each of which has a single series of rather 

 coarse deep and subcontiguous punctures, the series more or less sulci- 

 form, the third interval alone a little wider; setae erect, yellowish- 

 silvery, distinct; abdomen strongly and rather densely punctate, with a 

 deep basal impression in the male extending half way through the second 

 segment; legs piceous-black. Length (d") 4.5 mm.; width 2.0 mm. 

 Texas. 



This species belongs also near transversa but is smaller and much 

 more slender, with the rather elongate prothorax more rapidly 

 narrowing before the middle; the beak is more slender and the 

 elytral series more sulciform; the abdominal impression is deeper 

 and more conspicuous. 



Baris separata n. sp. — Much smaller and narrower than transversa, 

 with nearly similar coloration and lustre but with piceous-black legs and 

 more shouldered prothorax; beak much shorter, only very feebly arcuate, 

 scarcely three-fifths as long as the prothorax in the female and strongly, 

 rather densely punctured; prothorax shorter, a fourth or fifth wider 

 than long, the sides converging and nearly straight to about apical 

 third, there rapidly rounding to the short and feebly tubuloid apex; 

 punctures coarse, suboval, separated by half their diameters or less; 

 median smooth line very short, feebly defined; elytra only a fourth 

 longer than wide, two-thirds longer than the prothorax and a fifth wider, 

 the humeral callus rather prominent, the sides feebly converging; grooves 

 coarse, deep, rather distantly punctate, the intervals throughout only 

 just visibly or scarcely wider than the grooves, each with an impressed 

 sulcus of relatively coarse, subcontiguous punctures; setae erect, distinct, 

 yellowish-silvery; abdomen with the punctures very moderate in size 

 and well separated, generally by nearly twice their diameters medio- 

 basally. Length (9) 4.3 mm.; width 1.9 mm. Arizona (locality 

 unrecorded). One specimen. 



Smaller and much narrower than transversa, almost similar to 

 formalis in outline, but with the prothorax distinctly different, the 

 sides being more convergent from the base and more rapidly rounded 

 nearer the apex; the beak is much shorter, 



Baris tuckeri n. sp. — Form narrower and more elongate than usual in 

 this group, convex, shining, deep black throughout the body and legs;
