Baring 319 



series; setae very small and inconspicuous; abdomen with strong and 

 well spaced punctures, coarser and closer laterally, having (cf) a medio- 

 basal impression which is broad, shallow and not sharply defined; 

 pygidium closely punctate, finely below, coarsely above, the transverse 

 convexity. Length (cf 9) 3-5-4-I mm.; width 1.4-1.8 mm. Colorado, 

 Texas (Uvalde and Houston), Louisiana (Morgan City), Mississippi 

 (Vicksburg) and Alabama. 



In this series of eleven specimens, which holds together rather 

 well, there is considerable variation in elytral punctuation, the 

 coarsish punctures being in great part confused in some of them; 

 but further discriminatory work is unwarranted at present. The 

 male type specimen described above is labeled "Colorado." 



Baris austiniana n. sp. — Rather narrowly elongate-suboval, convex, 

 moderately shining, black throughout; beak (d^) short, arcuate, rather 

 closely punctate and only half as long as the prothorax, the latter a 

 fourth wider than long, the sides evenly and moderately arcuate almost 

 throughout the length; apex wholly unconstricted and much less than 

 half the basal width, the basal lobe wide, gradually formed and cuspidi- 

 form; punctures coarse, deep and very close-set, separated generally by 

 barely half their diameters, dense and rugulate laterally; median smooth 

 line imperfect, narrow or obliterated; scutellum very small, medially 

 impressed at apex; elytra fully two-fifths longer than wide, scarcely 

 wider than the prothorax and two-thirds longer, gradually obtusely 

 rounded behind about the middle, the sides parallel toward the prominent 

 humeral callus; grooves not very coarse, finely punctate, more coarsely 

 so and subcrenate at base; intervals nearly twice as wide as the grooves, 

 each with a single series of coarse and close-set punctures, the third wider 

 and with confused punctures; setae small, pale, glistening; abdomen 

 rather strongly, not densely punctate, having at base (d*) a deep tri- 

 angular impression, evenly concave at the bottom and extending, with 

 obtuse apex, not quite through the second segment. Length (cf 9 ) 

 3.65-3.8 mm.; width i. 4-1. 75 mm. Texas (i\ustin). Two specimens. 



The form of the prothorax in this species is peculiar, being 

 gradually narrowed throughout, with evenly arcuate sides; in 

 addition to this the marked male sexual characters are distinctive. 



Baris attonsa n. sp. — Oblong-oval, convex, shining, deep black through- 

 out; beak in the male moderately arcuate, finely, not densely punctate 

 and only half as long as the prothorax, the latter rather more than a 

 fourth wider than long, the sides subparallel and broadly arcuate, evenly 

 and broadly rounded and strongly converging in about apical third, the 

 apex unconstricted, the basal lobe small, cuspidiform; punctures moder- 

 ate and separated by their own diameters medially, dense and longi- 

 tudinally coalescent at the sides; median smooth line narrow, not entire; 

 scutellum very small, slightly impressed; elytra nearly one-half longer 

 than wide, barely at all wider than the prothorax and fully three-fourths
