prothorax fully two fifths wider than long, parallel basally, strongly and 

 obliquely narrowed in apical half, densely, rather finely punctate 

 throughout, the yellowish-brown vestiture somewhat close but in great part 

 coarsely hair-like ; elytra about one-half longer than wide, cuneiform, with 

 arcuate sides, rather prominent humeri, somewhat fine, punctured striae 

 and wide, flat and closely but not deeply punctate intervals, the vestiture of 

 elongate scales dense, yellowish gray, with irregular mottling of pale 

 brown, more distinct than in quercus, wholly concealing the surface. 

 Length, (J, 8.8 mm.; width, 3.8 mm. West Virginia. 



A little stouter than quercus, to which it is allied, and with the beak 

 about similar in length and curvature, but differing in the very long and 

 perfectly equal first two funicular joints, and in the denser and more 

 squamiform vestiture of the elytra. 



'I'he following is a subspecies of quercus : 



B. sparsellus n. subsp. — Nearly similar through(»ut to quercus^ but 

 with the elytra more cuneiform, more elongate and more gradually acute 

 behind, and with the second funicular joint ( A, ) but little shorter than the 

 first. Length, $ ^ 8.5 mm.; width, 3.6 mm. New Jersey. 



In quercus the elytra are less elongate, more rounded at the sides, 

 more obtuse at apex and with the first funicular joint in both sexes very 

 much longer than the second. The elytral vestiture does not fully 

 conceal the surface. Quercus is abundant from Massachusetts to West 

 Virginia. 



/)'. rectus Say. — Somewhat larger and more elongate than quercus, 

 blackish, the elytra, l»:gs and beak red-brown ; vestiture pale brownish- 

 yellow, in the form of very stout subscpiamiform hairs but much more 

 elongate than in quercus^ similarly in condensed patches on the elytra, 

 elsewhere darker and sparse, not concealing the surface ; beak ( 9 ) very 

 long, slender, perfectly straight to within a short distance of the apex 

 where it is bent downward ; antenn.'e very slender, the first funicular 

 joint much longer than the second ; prothorax about a liiird wider than 

 long, the sides subangulate at the middle, thence slightly diverging (not 

 parallel as in quercus) to the base and strongly sinuately converging to the 

 apex ; punctures dense, deep and rather coarse, the median line narrowly 

 impunctate ; elytra as in quercus but with less fine and more coarsely 

 j)unctured stria-, and less closely, asperulaiely punctulate intervals. 

 Length, 9 , 9.2-9.4 mm.; width, 3.9 mm ; length of rostrum, 9 . 10 5-1 1 o 

 mm. West Virginia.
