Baring 331 



as long as the prothorax and finely, loosely punctate; prothorax trans- 

 verse, not quite one-half wider than long, the upper profile evenly arcuate; 

 sides feebly converging and but slightly arcuate, gradually rounding and 

 converging in about apical third; basal lobe small but abrupt; punctures 

 coarse, separated by fully their own diameters, dense at the sides, the 

 median smooth line not definite; scutellum very small, rounded; elytra 

 two-fifths longer than wide, evidently but not greatly wider than the 

 prothorax and about twice as long, the sides slightly converging and feebly 

 arcuate, rapidly obtuse at tip; humeral callus rather large and prominent; 

 grooves rather coarse, deep and very abrupt externally, much less coarse 

 suturad; intervals not quite twice as wide as the grooves, each with a 

 single series of very fine and widely spaced punctures, the second and 

 third much wider than the others, but with the fine punctures still in 

 single series; setae very small and inconspicuous, the abdomen loosely 

 punctate, but somewhat coarsely latero-basally. Length (9 ) 3-0 mm.; 

 width 1.35 mm. Missouri (St. Louis), — Schuster. One example. 



This species is also allied to cBneomicans and has a somewhat 

 similar a?neous lustre, but the prothorax is not subevenly rounded 

 at the sides as in that form, and the interstrial punctures of the 

 elytra are much more minute. 



Bans mobilensis n. sp. — Small, polished, black, with slight aeneous 

 lustre, the legs black or nearly so; beak rather slender, finely, sparsely 

 punctate, strongly and evenly arcuate and three-fourths {&) or four- 

 fifths (9 ) as long as the prothorax, the latter short, one-half wider than 

 long, the sides subparallel and scarcely arcuate in basal, rounding and 

 converging in apical half, the apex wholly unconstricted; basal lobe 

 moderate, rather abrupt; punctures moderately strong, separated by 

 more than twice their diameters, coarser and close laterally, the median 

 impunctate line not definite or wanting; scutellum small, rounded; 

 elytra relatively long, about one-half longer than wide, a little wider 

 than the prothorax and between two and three times as long, the sides 

 feebly converging and slightly arcuate to the gradually obtuse apex, the 

 humeri prominent; grooves moderate, smooth, very deep, a little coarser 

 basally; intervals all with a single line of minute and widely separated 

 punctures, the second and third much wider than the others; setae 

 minute and indistinct; abdomen minutely, remotely punctulate, more 

 evidently latero-basally, not evidently modified in the male. Length 

 (of 9) 2.5-2.8 mm.; width 0.9-1.2 mm. Alabama (Mobile). Three 

 specimens. 



Allied also to the ceneomicans section, but very much smaller 

 and narrower than any of the others; it is also allied somewhat to 

 cerea, but diiTers in its narrower and more elongate form, shorter 

 prothorax and much longer beak. 



Baris subtropica n. sp. — Elongate and feebly subrhomboidal, convex, 

 polished, black, with evident subaeneous lustre, the legs black; beak
