to be added. As already stated by Dr. LeConte* the beak is stouter 

 and more coarsely sculptured (generally in Curculionidte) and the 

 last ventral segment impressed or foveate in the males. 

 I have divided the species into the following groups : 



Femora toothed. 



Vestiture dense, longer species. 



Funicle 7-jointed subpubescence group. 



Funicle 6-joiuted ang-ulatus group. 



Vestiture very sparse, subglabrous, frequently with metallic lustre. 



sulcipennis group. 

 Femora mutic. 

 Funicle 7-jointed. claws toothed. 



Elytra distinctly tuberculate ■v«rv«»A.. . (tuberculipennis) group. 



Elytra not tuberculate, generally muricate on the declivity. tA>f\A^W » obOu » 



Funicle 7-jointed, claws simple squamatus group. 



Funicle 6-jointed, claws simple septentrionis group. 



subpubescence group. 



■ Species above median size, having the antennal funicle 7-jointed, 



the claws bifid, or distinctly toothed, rarely (isolatus) simple. They 



are more or less densely scaly or pubescent and may be distinguished 



as follows : 



Claws armed with a long tooth, nearly bifid; less densely scaly or pubescent. 

 Above clothed with fine brownish pul)escence intermixed with large white 



scales siibpiilx'sceiis. 



Above uniformly clothed with gray or pale ochreous scales sifHiieiitiiiii. 



Scales white, not uniform, intermixed with coarse hair- . • .!>»t'rie>*elo«»iis. 



Claws simple; hirsute isolatus. 



Claws armed with a short, stout tooth. 

 Scales dense, a conspicuous scutellar spot. 



Prothorax cribrate riKlis. 



Prothorax more finely ])unctured sericaiis. 



V. sub|»iil»es<'dis Lee. — Subrhom})oidal, jiitcliy black, above clothed with 

 fine, i)ale brownisii pubescence, intermixed on the elytra with scattered, large, 

 white scales. Beak slender, curved, about as long ( % ), or longer ( 9 ) than the 

 prothorax, slightly tapering towards the apex, finely striate and punctured in its 

 liasal half, more finely punctured and shining towards the apex, antennae slender, 

 inserted at the middle ( % and 9 )- ^''^t and second joints of funicle elongate, 

 second slender, joints 3-4 very little ( ^ ) or distinctly longer ( 9 ) than the outer 

 joints, club large, ovoidal, acuminate. Eyes round, not prominent, completely 

 concealed in repose by the prominent postocular lobes. Head rather coarst^ly 

 punctured, coarsely pubescent ; prothorax wider than long, fully two-fifths wider 

 at the base than at the apex, latter strongly constricted behind the apiciil margin, 

 sides broadly rounded, lateral tubercles distinct, placed transversely, dorsal sulcus 

 entire, less profound at the middle, disc densely and rather coarsely punctunnl ;
