well separated punctures, the second and third wider and with smaller 

 punctures, somewhat confused on the third, the setae small but glistening 

 and distinct; abdomen with moderate and rather widely separated 

 punctures, becoming coarser and somewhat close laterally. Length ( 9 ) 

 3.0 mm.; width 1.4 mm. Pennsylvania (locality unrecorded). 



The unique type represents a species not closely allied to any 

 other, but belonging to the socialis series; it has a very feeble 

 rounded indentation, not at the abdominal base but at the centre 

 of the first segment; this, in connection with the short beak, may 

 indicate the male, but the probabilities are that it is a female. 



Baris sculptiventris n. sp.— Oblong-suboval, convex, black, shining and 

 with barely any metallic lustre above, the legs rufescent; beak in the 

 female rather stout, strongly, evenly arcuate, rather densely punctate 

 and as long as the prothorax, which is not quite one-half wider than long, 

 with parallel and feebly arcuate sides, rounding strongly and rapidly in 

 apical third or fourth; punctures coarse, deep, close-set, separated by 

 half their diameters, denser laterally; smooth median line obliterated; 

 basal lobe broad and very short, the scutellum very small, rounded, 

 impressed; elytra two-fifths longer than wide, only slightly wider than 

 the prothorax and not quite half longer, the sides subparallel, slightly 

 arcuate, gradually obtuse at apex, the humeri subprominent; grooves 

 moderate, very deep, with smooth sides, the punctures along the bottom 

 well separated; intervals barely twice as wide as the grooves, each with a 

 single series of small but deep and distinct, well separated punctures, the 

 second and third but little wider, the latter with the series more uneven; 

 setae minute and inconspicuous; abdomen strongly, extremely densely 

 punctate, with the punctures subcoalescent longitudinally. Length (9 ) 

 2.8 mm.; width 1.28 mm. Florida (Key West). A single example. 



A remarkably distinct species in the peculiar strong and dense 

 compressed sculpture of the abdomen; in this respect it resembles 

 punctiventris, from Louisiana and Missouri, though having the 

 abdominal sculpture even denser, but it differs in the more oblong 

 and less oval outline, shouldered and not laterally subevenly 

 rounded prothorax and in the still longer beak. 



The three following species are notably narrow, slender, convex 

 and subcylindric, more or less resembling macra, aperta and incon- 

 spicua: 



Baris fracta n. sp. — Elongate-suboval, convex, shining, piceous-black, 

 the elytra and legs obscure rufous; beak in the male closely punctulate, 

 black, feebly arcuate, slender and three-fourths as long as the prothorax, 

 the latter a fourth wider than long, the sides moderately converging, 

 broadly, subevenly arcuate, rather abruptly oblique in apical third or 

 fourth, the apex unconstricted; punctures rather coarse, deep, separated
