3o6 Memoirs on the Coleoptera 



beak feebly arcuate, two-thirds as long as the prothorax and densely 

 punctate, the depression separating it from the head well marked; 

 prothorax rather more than a fourth wider than long, the sides subparallel 

 and broadly arcuate nearly to apical third, there broadly rounding and 

 converging to the obsolescent apical constriction; punctures medially 

 moderate and distinctly separated, coarser and dense laterally, the 

 median smooth line small and almost obliterated; basal lobe moderate 

 but rather abrupt; eh'tra nearly one-half longer than wide, a fifth wider 

 than the prothorax and four- fifths longer; grooves deep but only moder- 

 ately coarse, finely punctate; intervals distinctly wider than the grooves, 

 the punctures subcontiguous, rather coarse, forming very feebly im- 

 pressed series, not so coarse and more confused on the wider third interval; 

 setae pale, glistening and very short; pygidium transversely oval, convex, 

 moderately but very densely punctate; abdomen in the male shining 

 but rather coarsel}^ closely punctate, with a moderately large but deep, 

 unusually abrupt impression, not intruding distinctly upon the second 

 segment. Length (cf) 4.5 mm.; width 1.8 mm. Arizona (Tugson), — 

 J. F. Tucker. A single specimen. 



An isolated species of the transversa group, much smaller and 

 more slender than the latter and having a more parallel and laterally- 

 rounded prothorax than in any other; the humeral callus is moder- 

 ate but rather abrupt and the sides are parallel, rounding in about 

 posterior third; the elytra are relatively much more elongate than 

 in the other species. 



Baris longulicollis n. sp. — Elongate, convex, shining, black, the elytra 

 and legs piceo-rufous; beak fully three-fourths as long as the prothorax 

 in the male, feebly arcuate, not very closely punctate; prothorax large, 

 very nearly as long as wide, the sides feebly converging from the base 

 nearly to apical third and but just visibly arcuate, thence rounding and 

 converging to the subobsolete apical constriction; punctures coarse, 

 deep, somewhat close-set, being separated by nearly half their diameters, 

 not coarser but close laterally, the smooth median line narrow and short; 

 elytra two-fifths longer than wide, a sixth wider than the prothorax and 

 only three-fifths longer, gradually rounding at the sides behind the 

 middle, with the humeral callus very moderate in prominence; grooves 

 moderately deep, very abrupt as usual; intervals rather evidently wider 

 than the grooves, each with an entirely unimpressed single series of 

 moderately coarse, close-set but separated punctures, the second and 

 third broader and with confused punctures; pale setae very small; male 

 abdomen with moderate but deep punctures, separated medio-basally 

 by rather more than their own diameters, and also with a shallow basal 

 impression, not extending to the second segment and having the bottom 

 line more acutely defined. Length (cf ) 5.2 mm.; width 2.25 mm. New 

 Mexico (Las Vegas). A single example, taken by Mr. Meeske. 



There is no other species of this group with which the present 

 harmonizes very closely; it is narrower than transversa and differs 

 in coloration, as well as in many other ways.
