Pennsylvania, North Carolina, Georgia, Florida, -Mississippi, 

 Texas and Iowa. I have before me about fifty specimens, one of 

 which, from Iowa, has the prothorax slightly more elongate than 

 any of the others. 



34 Baris Slllisiniilis n. sp. — Oval, rather robust and but moderately 

 convex, black throughonl, liijgbly polished aud with a somewhat strong aeneous 

 metallic lustre. Head minutely, the beak rather strongly but not very densely 

 punctate, the latter robust, evenly, moderately arcuate, short, about three- 

 fourths as long as the prothorax ; antennae normal. Prothorax somewhat 

 transverse, fully two-fifths wider than long; sides just visibly convergent 

 and very feebly arcuate to apical fourth, then strongly but not prominently 

 rounded, thence strongly convergent and straight to the apex, which is trans- 

 versely truncate ; base straight and very feebly oblique from the small and 

 feeble median lobe to the sides ; disk with narrow, feebly defined, almost 

 entire median line, the punctures moderate iu size and depth, not very dense, 

 about two-fifths as wide as the scutellum and generally separated by nearly 

 their own diameters. Scutellum small, very feebly impressed. Elytra ample, 

 one-third longer than wide, a little moi'e than twice as long as the prothorax, 

 and, at the moderately tumid humeri, slightly wider than the latter ; sides 

 behind the humeri just visibly convergent, the apex rather gradually, serai- 

 circularly rounded ; disk with deep, moderately coarse, minutely, feebly 

 punctate grooves, the intervals flat, about twice as wide as the grooves, each 

 with a single series of fine but rather deep and distinct, moderately close-set 

 punctures, which are confused on the third interval but not at all on the 

 second, and also confused on the fifth toward base ; setae very small, not con- 

 spicuous. Abdomen rather coarsely, strongly and quite densely punctured. 

 Legs coarsely but feebly, sparsely punctate ; tibi;e straight ; tarsal claws 

 small. Length 3.4-4.0 mm. ; width 1.5-1.9 mm. 



Pennsylvania; Indiana; Missouri. 



This species somewhat resembles a large covfinis, but has the 

 interstitial punctures more close-set, the abdomen more densely and 

 rugosely punctured, and the beak decidedly shorter and thicker. 

 The prosternum is very feebly impressed and separates the coxai 

 by about one-half of their own width. 



35 Baris SOCialis n. sp. — Oblong-oval, rather slender, moderately con- 

 vex, polished, black throughout. Head and beak finely, sparsely punctate, 

 the latter not very densely so at the sides, feebly, evenly arcuate throughout, 

 three-fourths as long as the prothorax ; antennae normal. Prothorax two-fifths 

 wider than long, the sides slightly but distinctly convergent and feebly 

 arcuate to apical fourth, then more strongly rounded, thence moderately 

 convergent and straight or just visibly sinuate to the apex, which is broadly, 

 feebly arcuate ; base subtransverse, a little less than three times as wide as 

 the head, the median lobe small but distinct ; disk ratiier feebly convex, not
