5*18 Goleopterological Notices^ VII. 



seems to be a little longer in the female, and the last ventral is 

 more obviously prolonged at apex in a short rounded lobe, as in 

 many Euplecti. 



This species is allied to riparius, but in the latter the antennae 

 of the male are shorter, with a much larger and more globose tenth 

 antennal joint, and it differs further in having a more convex, 

 more finely and asperately punctate, steeper and setigerous frontal 

 declivity, smaller foveas, which are united by a continuous feeble 

 ambient sulcus, a narrower and more trapezoidal pygidium, a 

 longer and more contorted apical tibial process, and in numerous 

 other features. Riparius is common in the Ohio valley, from the 

 headwaters of which, in Westmoreland Co., Pa., I have a small 

 series taken by Mr. Schmitt ; the present species is its homologue 

 from the Atlantic maritime regions. 



B. bari'ingtoni n. sp. — Eather stout and strongly convex, clear and 

 very pale rufo-testaceous throughout, shining, the elytra minutely, sparsely 

 punctulate, the head grantilarly and subrugosely, the pronotum and hasal 

 parts of the tergum finely, sparsely and asperately ; pubescence moderate in 

 length, coarse, recurved and somewhat sparse. Head slightly transverse, dis- 

 tinctly wider than the prothorax, convex, shining toward base, densely and 

 coarsely sculptured anteriorly, the punctures umbilicate, thefovese large, deep, 

 nude, subbasal and separated by but little less than % the entire width, the 

 intervening surface strongly convex, finely carinate; sublateral carinse fine and 

 feeble ; eyes moderately large, very convex and prominent, at nearly their own 

 length from the base, the tempora behind them not at all prominent, very 

 rapidly convergent and broadly arcuate to the neck; dorsal impressions feeble, 

 only extending a short distance from the fovese, there being no trace of a cir- 

 cumambient sulcus ; frontal surface convex, without trace of antennal tuber- 

 cles, obtusely truncate with a median sinus from a vertical viewpoint, the 

 apex just before the line of the antennae vertical and deeply and smoothly ex- 

 cavated, the excavation subsemicircular in form, with its lower edge produced 

 in the middle in a quadrate horizontal process, deeply bifid at tip ; at the ex- 

 treme lateral limits of the excavation the sides extend downward in a lamel- 

 ate setose process, partially enclosing the antennal cavities, and, between this, 

 and the central bifid process, there is a small, acute, suberect and setiferoua 

 tubercle ; clypeus broadly produced in the middle in a rounded lobe, with the 

 surface very convex, the summit posteriorly feebly carinate under the bifid 

 process of the front, the carina bearing some long sparse radiating setse ; man- 

 dibles stout, the inner margin multi-serrulate, the arcuate tip moderately 

 produced and aciculate. Antennie rather less than }4 ^s long as the body, 

 somewhat slender, the club only moderately thick, the basal joint less than % 

 longer than wide, flattened and punctate within, the lower contour rounded 

 toward base, the upper surface emarginate at apex for the reflexion of the 

 funicle about half way to the base ; second joint not quite as long as the third
