NORTH AMERICAN COLKOPTERA. 57 



A, pubripeiliiis Horn.— Oblong oval, feebly convex, piecous black, moder- 

 ately shining, elytra <lull red or reddish yellow, legs brown, tarsi nnich ])aler. 

 Antennse ferrnginous, the club somewhat darker, jialpi pale. Head moderately 

 convex, without trace of frontal tubercles, surface shining with very fine sparse 

 l)nnctures, a few coarser puiu'tures near the sides. Clyijeus nearly semicircular, 

 slightly obtuse in front, but without trace of emargination, gense moderately 

 l)roniinent, but obtuse. Thorax nearly twice as wide as long, slightly narrowed 

 in front, sides feebly arcuate, more distinctly so anteriorly, the hind angles 

 broadly rounded, base feebly arcuate, without trace of marginal line, disc mod- 

 erately convex, sparsely very finely punctate, a few coarse punctures along the 

 base, others more numerous near the side. Elytra as wide as thorax, the humeri 

 distinct, not obtuse ; sides feebly arcuate, disc rather finely striate, strife with 

 fine punctures, the intervals feebly convex, biseriately punctulate, on some of 

 the intervals irregularly punctulate ; color of elytra dull red or reddish yellow, 

 the apical third and sides narrowly slightly darker as if stained, the pubescence 

 yellowish, extremely fine and short, more distinct on the apical darker region. 

 Mesosteruum opaque, sparsely punctate. Metasternum sparsely punctate at 

 middle, more densely, also opaque at the sides. Abdomen distinctly, not closely 

 punctate. Anterior tibiaj smooth in front, tridentate externally and crenate 

 above, the first tarsal joint as long as the second. Posterior femora sparsely 

 punctate, a series of coarse punctures near the knee, the first tarsal joint as 

 long as the next four together. Length .28-.30 inch ; 7-7.5 mm. 



The only differences that seem to be sexual are found in tlie less 

 shining elytra of the female with the thorax somewhat narrower and 

 tlie sides less arcuate. 



This species is easily known by the nearly semicircuhir clypfus, 

 the reddish elytra finely pubescent near the apex, the pale red tarsi, 

 the fii'st joint of the hind tarsi being of an unusual length. It rep- 

 resents in our ftvuna luridus, of Elurope, and by the ado])tion of the 

 groups proposed by Erichson, would be included witli that species 

 and depresms in Group I. 



Should the pubescence be entix'ely removed by accident from any 

 specimens they would doubtless be referred to Group I and the table 

 would lead directly to depre-%ms and indicate its relationship. 



Occurs in Canada and Pennsylvania ; taken rather abundantly by 

 Mr. Ulke in Maryland. 



A. subtriincatus Lee. — Moderately elongate, parallel, body beneath dark 

 brown, head and thorax piceous black, sides of thorax, elytra (the suture nar- 

 rowly darker) and legs yellow. Antenuie testaceous, club fuliginous. Head mod- 

 erately convex without trace of tubercles, sparsely punctate % , or coai-sely 

 densely punctate at sides and front J ; clypeus truncate with very feeble trace 

 of a broad emargination, the angles broadly rounded, sides feebly arcuate, geniv 

 slightly prominent and obtuse. Thorax moderately convex, slightly narrowed 

 in front, the sides feebly arcuate, hind angles very obtusely rounded, base arcuate 

 with very fine marginal line ; disc with moderate punctures nearly e(iual in size.
