than twice as long, the sides barely visibly converging and broadly arcu- 

 ate, obtusely rounded at apex, the humeral callus rather feeble; grooves 

 moderately coarse, deep, the intervals about one-half wider than the 

 grooves, the second and third a little wider, all with a single series of 

 small and well separated punctures; abdomen rather coarsely, deeply 

 and closely punctate, the punctures forming an uneven transverse series 

 on the third and fourth segments, having in the male a feeble medio- 

 basal impression, obsolete near the apex of the second segment; pygidium 

 convex, with deep though moderate and not densely crowded punctures. 

 Length (cf) 3.1 mm.; width 1.3 mm. North Carolina (Asheville). 

 One example. 



This species can be compared only with socialis, but differs in the 

 shorter and less sculptured beak and stronger and denser abdominal 

 punctuation; the prothorax is slightly more abbreviated, but much 

 less so than in the more metallic carolinensis and confinis. 



Baris pupilla n. sp. — Oblong-suboval, convex, strongly shining, black, 

 with evidently aeneous lustre above, the legs black; beak rather stout, 

 barely arcuate, rather closely punctulate and two-thirds as long as the 

 prothorax, the latter a fourth wider than long, the sides broadly arcuate, 

 gradually less so and subparallel in about basal half; punctures strong, 

 separated by about one-half more than their diameters, dense and longi- 

 tudinally confluent at the sides, very minute medio-apically, the smooth 

 median line narrow but almost entire, the basal lobe small; scutellum 

 very small, rounded ; elytra a third longer than wide, slightly wider than 

 the prothorax and two-thirds longer, the sides feebly converging and 

 broadly arcuate, the apex broadly obtuse, the humeri prominent, finely 

 punctate, the tip polished; grooves rather coarse, deep; intervals one- 

 half wider than the grooves, each with a single series of small and well 

 separated punctures, slightly confused on the third, the second and third 

 wider than the others; setae minute but glistening as usual; abdomen 

 finely, sparsely punctate medio-basally, rather strongly and closely else- 

 where, having at base a feeble transversely oval impression in the male. 

 Length (cf) 2.7 mm.; width 1.2 mm. North Carolina (Asheville). 

 One example. 



Allied evidently to (srea, but differing in the coarser and closer 

 pronotal punctures and in the almost evenly arcuate thoracic sides, 

 the outline being more shouldered anteriorly in cerea. 



Baris modicella n. sp.— Parallel, subcylindric, convex, shining, black, 

 with barely evident subaeneous lustre above, the legs piceous; beak in 

 the male very feebly arcuate, slightly punctulate and nearly four-fifths 

 as long as the prothorax, the latter short, one-half wider than long, the 

 sides almost parallel, very feebly arcuate, rapidly rounding and oblique 

 between apical third and fourth, the basal lobe abrupt, well developed, 

 rounded; punctures fine or moderate and sparse, becoming gradually 

 rather coarse and moderately close laterally; median smooth line want- 

 ing; scutellum very small, rounded; elytra not quite a third longer than
