short and obtusely rounded, less than one-half longer than wide, aljout two and 

 one-half times as long as the prothorax, coarsely and rather closely punctate ; 

 pubescence rather long, suberect, coarse and bristling but not dense ; antennal

 punctate spot near the apex at inner two-fifths { $ )■ Length 2.0 mm.; width

19 — Subserial setL« of the elytra very long and conspicuous ; body large, coarsely 

 punctured, the elytra not very closely and sometimes subserially ; sexual differences 

 very marked, the male stout, with the antenna very thick, the elytra one- 

 half longer than wide, but little wider than the prothorax and barely three 

 times as long, the female much narrower and more elongate, with thinner an- 

 tennEE and smaller prothorax, having rather more prominent but otherwise similar 

 angular nodes, the elytra three-fourths longer than wide, much more than three 

 times as long as the prothorax and distinctly wider, the punctures somewhat more 

 sparse and more inclined to serial arrangement ; callous spots of the pronotum small 

 but obvious ; angular truncatures large but barely as long as the distance thence 

 to the spicules. Length 2.6-2.7 mm.; width I.I-I.2 mm. North Carolina. 

 (A.sheville) amputatus, sp. nov. 



Subserial setce only moderately distinct ; body much smaller ; angular nodes of the 

 prothorax well developed but not prominent, the callous spots small but distinct; 

 antennal club broad and well developed 20 



20 Body parallel, dark rufo-ferruginous in color, the pubescence rather abundant 



and conspicuous though only moderately long ; prothorax scarcely narrower 

 than the elytra in the male, distinctly narrower in the female, strongly and closely 

 punctured, the angular nodes large and conspicuous, as long as the distance 

 thence to the spicules, or even longer in the male ; elytra, in the latter sex, one- 

 half longer than wide, less than three times as long as the prothorax, coarsely 

 and closelv punctured, in the female decidedly more elongate, more than three 

 times as long as the prothorax and less closely though equally coarsely, punctured ; 

 a feebly eroded adventitious second, line parallel to the posterior subsutural stria, 

 is sometimes evident. Length 2.0-2.2 mm. ; width 0.85 mm. South Carolina 

 to Illinois ; [crinitus Zimm.] croceus Zimm. 



Body more oval and rather more convex, pale flavo-ferruginous throughout ; prothorax 

 smaller and more rounded at the sides than in croceus, the angular lobes much 

 smaller, distinctly shorter than the distance thence to the spicules, the punctures 

 strong and rather close-set, the posterior callous spots more obvious than the an- 

 terior ; elytra three-fifths longer than wide, rather strongly rounded at tip, about 

 three times as long as the prothorax, the punctures only moderately coarse, deep, 

 decidedly close-set and inclined to subserial arrangement, the pubescence shorter 

 and less con.spicuous than in croceus ( $ ). Length 1. 9 mm. ; width 0.75 mm.

21 — Antennal club broader, with its basal joint scarcely smaller than the second as 

 usual ; body rather small, oblong, dark testaceous in color, the pubescence 

 moderately long and sparse ; prothorax very nearly as wide as the elytra, strongly 

 transverse, three-fourths wider than long, strongly and closely punctured, the
