440 Coleopterological Notices, VI, 



head and pronotum exceedingly minute and occupied almost en- 

 tirely by the base of the hairs. Head one-half as wide as the pro- 

 thorax, the antenna rather long, gradually and evenl}' incrassate 

 through the last six or seven joints, the penultimate slightly 

 wider than long. Prothorax nearly' one-half wider than long, the 

 basal angles rather abruptly prominent posteriorly, right and not 

 distinctly rounded. Elj-tra not quite as long as wide, somewhat 

 distinctly longer than the prothorax, perceptibly narrowed from 

 the base, with the sides ver}^ feebly but evenly arcuate, the 

 disk strongly convex, perfectly even in coloration, somewhat 

 coarsely and feebly imbricate and minutely, very densely pubes- 

 cent. Abdomen quite evenl}' tapering from base to tip, the erect 

 setae short and inconspicuous except at the apex. Length 2.0- 

 2.25 mm.; width 1 15-1.3 mm. 



New York, New Jersey and Pennsylvania. The male has a 

 feeble rounded median sinuation at the apex of the fifth ventral, 

 the sixth having a deep rounded sinuation at the middle, about 

 three times as wide as deep and with the external angles very 

 broadly arcuate. The epipleura? are wide, punctulate and pu- 

 bescent throughout, subhorizontal and broadly impressed in 

 about basal half. 



This species is allied to the European pubesce^is^ but is more 

 convex, with more gradually incrassate antennte, and differs also 

 in eoloi'ation and decidedly in sculpture. In puhescens Payk., 

 of which I have before me a series carefull}' determined by Mr. 

 Reitter, the elytra are smaller and more depressed, and are gener- 

 ally rufons with the suture and flanks blackish ; the antennaj are 

 much more rapidl}" and strongly- incrassate through the outer five 

 joints, and the penultimate joints are full}' as long as wide ; the 

 sinuation of the fifth ventral is much wider and the rounded notch 

 of the sixth narrower, not more than twice as wide as deep, with 

 the external angles much less broadl}' rounded. In the European 

 species the elytral sculpture is ver}' much finer, denser and less 

 distinctly imbricate, this being noticeable in all the numerous 

 specimens compared, even under the low powers of the hand lens. 



The recently published lists of Coleoptera common to Europe 

 and America have in several cases been carried much too far, and 

 numerous instances occur, especially in the Staphylinidfe, wiiere 

 species closely allied b}* reason of community of descent have 

 been regarded as identical ; in some cases the species which have
