Baring 321 



elytra two-fifths longer than wide, a fifth or sixth wider than the pro- 

 thorax and nearly twice as long, the sides arcuate and slightly converging 

 to the moderately obtuse apex, the humeral callus rather prominent; 

 grooves somewhat coarse, very deep and abrupt; intervals one-half 

 wider than the grooves or less, each with a single series of moderate but 

 strong punctures, sometimes so close-set as to produce a feeble impression 

 of the line, the second and third wider, with the punctures much finer 

 and confused; setae very small; abdomen strongly and closely punctate, 

 with a feeble median concavity at base in the male. Length (cf 9 ) 

 4.1 mm.; width 1.75 mm. Oregon (The Dalles). Two specimens. 



To be known very readily by the densely punctate beak and by 

 the longitudinally subimpressed narrower of the strial intervals, 

 remindful somewhat of a character often observable in the tra^is- 

 versa group of the genus; it is in no way allied otherwise to that 

 group however. 



The three following form part of a small group represented by 

 oblongula, porosicollis and suhsimilis, having close-set pronotal 

 punctures, which are moderate in size as a rule: 



Baris appalachia n. sp. — Elongate-suboval, convex, deep black and 

 rather shining, the legs with a feeble piceous tinge; beak cylindric, not 

 very stout, arcuate, finely and not very closely punctate and nearly 

 three-fourths as long as the prothorax in the female; prothorax evenly 

 arcuate in profile, fully a third wider than long, the sides feebly converging 

 and slightly arcuate, gradually broadly rounding and converging in about 

 apical third, the basal lobe small; punctures rather small in comparison 

 with those of attonsa, close-set, dense and longitudinally confluent at 

 the sides, the smooth median line narrow and short; scutellum small, 

 quadrate, emarginate at apex; elytra one-half longer than wide, more 

 than twice as long as the prothorax and a fifth or sixth wider, gradually 

 rounding behind from near the middle, obtuse at apex, the humeral 

 callus not strikingly prominent; grooves not very coarse, deep, with 

 small and separated punctures; intervals some with single series of 

 small but distinct punctures, others with the punctures confused along 

 the middle, the second and third wider; setae very small and incon- 

 spicuous; abdomen with moderate deep close punctures, coarser at the 

 sides; legs rather short. Length (9 ) 4-3 nim.; width 1.75 mm. Penn- 

 sylvania (locality unrecorded). 



Distinguishable easily from stihsimilis by its slightly larger size, 

 more elongate outline and much more close-set and relativ^ely 

 smaller punctures; the following is closely related to appalachia: 



Baris demissa n. sp. — Shorter and much stouter than appalachia and 



stouter than subsimilis; beak as in the former, the prothorax with 



similar moderate and very close-set punctures but still shorter, fully 



two-fifths wider than long; elytra more oval and abbreviated, with
