3i8 Memoirs on the Coleoptera 



Very closely allied to the preceding and possibly no more than a 

 subspecies, but the thoracic punctures are not quite so coarse and 

 are still denser, the pygidial punctures coarser and the general 

 form of the body rather more parallel and subcylindric. The male 

 abdominal characters may prove to be quite different. 



Baris cribrifera n. sp. — Oblong, convex, rather stout, black throughout, 

 moderately shining; beak arcuate, rather finely, closely punctate, half 

 as long as the prothorax (cf ) and barely longer (9 ); prothorax large, a 

 fifth wider than long, the sides feebly converging, slightly arcuate, 

 rapidly rounding and strongly converging anteriorly, the apex wholly 

 unconstricted, the basal lobe very bluntly cuspidiform, gradually formed; 

 punctures notably coarse and deep, close-set, sometimes subcontiguous, 

 denser laterally; median smooth line obliterated or very narrow; scutel- 

 lum small, quadrate; elytra a third to two-fifths longer than wide, only 

 just visibly wider than the prothorax and scarcely three-fifths longer, 

 the sides subparallel anteriorly, with prominent rounded humeral callus; 

 apex gradually rounding from near the middle; grooves not very coarse, 

 deep, finely lineato-punctate; intervals twice as wide as the grooves, 

 with coarse and close-set confused punctures, sometimes forming single 

 series, the second and third wider, with the confused punctures not quite 

 so coarse as a rule; setse very small, sparse and inconspicuous; abdomen 

 somewhat strongly, not very closely punctate, with an extremely feebly 

 impressed or scarcely more than flattened medio-basal area; pygidium 

 convex, very densely punctate. Length (cf 9 ) 4.0-4.4 mm.; width 

 2.0-2.1 mm. North Carolina (Southern Pines) and Pennsylvania 

 (Harrisburg), — Manee and Champlain. Nine specimens. 



Distinguishable from inter stitialis by the more elongate-oblong 

 form, larger and much less abbreviated prothorax, less developed 

 elytral setse and other characters. 



Baris vagans n. sp. — Oblong-oval, strongly convex and polished, deep 

 black, the legs not paler; beak in the male arcuate, finely, not closely 

 punctate and three-fifths as long as the prothorax, which in profile 

 slopes in front with unusual abruptness and steepness; prothorax 

 scarcely a fourth wider than long, the sides broadly arcuate, becoming 

 straighter and subparallel behind and more arcuate anteriad; apex 

 completely unconstricted, the basal lobe very short, obtusely rounded; 

 punctures very coarse and separated by more than their diameters 

 medio-basally, but close and less coarse anteriorly, becoming fine at the 

 apical margin, coarse and dense laterally; smooth median line narrow, 

 not attaining the apex; scutellum very small, subquadrate; elytra two- 

 fifths longer than wide, only just visibly wider than the prothorax and 

 three-fourths longer, the sides feebly converging and broadly arcuate 

 behind the rather prominent humeral callus, gradually broadly rounded 

 behind;- grooves rather coarse, very deep; intervals not quite twice as 

 wide as the grooves, with single series of moderately coarse and separated 

 punctures, the second and third wider and with confused or uneven
