longer, the outline and humeral callus nearly as in the preceding; grooves 

 moderate, not coarse, punctate; intervals twice as wide as the grooves, 

 the third and fifth much wider and with confused punctures, the narrower 

 intervals with rather uneven single series, all the punctures notably 

 close-set and very moderate in size; setae small but distinct, glistening; 

 abdomen with somewhat small and sparse punctures, becoming rather 

 coarser and closer peripherally, having, in the male, are extremely feeble 

 medio-basal impression. Length (d^) 3.8 mm.; width 1.6 mm. North 

 Carolina (Southern Pines), — Manee. 



This species may be distinguished from inter ^titialis, where also 

 the interstitial punctures are in great part confused, by its much 

 narrower form, less coarse pronotal punctures toward the median 

 line and much finer elytral sculpture. 



Baris intacta n. sp. — Narrowly oblong-oval, convex and deep black 

 throughout and polished; beak slender, moderately punctate, feebly, 

 arcuate and three-fifths as long as the prothorax in the female; prothorax 

 subevenly arcuate above in profile, rather short, fully a third wider than 

 long, the sides converging and arcuate from base to apex, a little more 

 arcuate anteriorly, the basal lobe small; punctures strong, separated by 

 fully their own diameters, denser laterally, the smooth median line nar- 

 row, not extending to the apex; scutellum small, rounded; elytra two- 

 fifths longer than wide, barely wider than the prothorax and not quite 

 twice as long, the sides converging and broadly arcuate, moderately 

 obtuse at apex, the humeral callus prominent; grooves moderately 

 coarse, deep; intervals two to nearly three times as wide as the grooves, 

 each with a single loose line of notably small but distinct punctures; 

 setae minute and barely observable; abdomen rather strongly though 

 loosely punctate; pygidium closely but not very coarsely punctate, 

 finely carinulate; femora somewhat slender. Length (9) 3-35 mm.; 

 width 1.4 mm. Mississippi (Agricultural College). 



Not closely allied to any other described species; it differs from 

 the equally polished tumescens in its narrower form, smaller and 

 closer pronotal punctures and shorter prothorax; the serial punc- 

 tures of the elytra are very nearly as small as in monticola and more 

 separated. 



Baris cdlumbiana n. sp. — Larger, more elongate-suboval, convex, 

 shining, black, the legs slightly picescent; beak feebly arcuate, very 

 densely and rather strongly punctate, about two-thirds as long as the 

 prothorax in the male; prothorax with evenly arcuate upper profile, a 

 fourth wider than long, the feebly converging and slightly arcuate sides 

 more rounded in about anterior third, then strongly converging, feebly 

 sinuate apically, the basal lobe moderate; punctures strong, rather close- 

 set, becoming gradually a little larger and very dense laterally; smooth 

 median line narrow, parallel, extending very nearly from base to apex; 

 scutellum small, slightly transverse, longitudinally and feebly impressed;
