geneous mass of specimens, of which the extremes seem mis- 

 placed. Such a result is, however, preferable, in our opinion, to 

 attempting to associate names with individual specimens or even 

 groups of specimens without strongly correlated structural and 

 biological characteristics. In retaining (as species) inirddlis, 

 confusor. haciili and JunucraUs, we have been guided in part by 

 their recognition by field workers and their established ecological 

 relation with oaks of different species. 



388 (- -). BAI.ANIXUS PABDALIS Chittenden, 1908-a, 25. 



Oval, robust. Dark reddish-brown to piceous, densely clothed with 

 clay-yellow scales; elytra strongly mottled with small brown spots, these 

 sometimes united and forming bands. Beak of female four-fifths as long 

 as body, that of male less than two-thirds, enlarged at base and apex, 

 moderately curved. First funicular joint longer than second; scape as 

 long as next three joints. Thcrax one-fourth wider than long, strongly 

 curved near middle, narrcAvecl near apex, the lateral pale stripe well de- 

 veloped. Femora strongly clavate. not reaching beyond elytra, the tooth 

 large and prominent, its entering angle nearly right. Fifth ventral of male 

 flat at middle, strongly bilobed at apex. Length 7.2 7.6 mm. 



Wells County, Ind., scarce; Sept. S. Occurs from Rhode Is- 

 land to North Carolina, westward to Arkansas and Texas. Bred 

 from acorns of (Jm'rcits plfitiiiionlt'N, rcliilhm, pcdiinciilata. alba 

 and priitHK. This species differs from nfisicus by the shorter and 

 thicker beak with apical extremity enlarged in male, by shorter 

 femora and more spotted elytral vestiture. 



Casey (1910, 123) separates somewhat doubtfully B. virgin ic-us on 

 account of its longer legs, beak of female longer, not enlarged apically in 

 either sex. Length 7.2 7.6 mm. West Virginia. 



389 (11,213). BAI.A.MXUS COXFVSOK Hamilton, Can. Ent., XXV, 1893, 309. 



Form, shape, color and vestiture similar to that cf uasicns. the sublat- 

 eral stripe of paler scales on thorax and transverse pale band near apical 

 third of elytra more evident. Beak about as long as elytra, or two-thirds 

 the length of body in female, shorter in male, thickened and punctured at 

 base. First joint of funicle longer than second. Femora stouter, and more 

 strongly inflated than in nasicus with the tooth much smaller and oblique. 

 Male with pygidium convex, punctate, covered apically with long yellow 

 hairs; fifth ventral with subglabrous space at tip, a tuft of hair en each 

 side. Length 6.5 7.5 mm. 



Lake County, Indiana, rare; July l*. Beverly Hills, Chicago. 

 111., May L'1. Batavia, X. Y. ; July 4 ll*. Known from Massa- 

 chusetts and New York to northern Illinois, south to North Car- 

 olina. Distinguished from IKIX'H-IIN by the shorter beak, and from
