AMERICAN COLEOPTERA, 143 



C. fasciatus. =Bosi/-icAMs fasciatus Say, Journ. Acad. Nat. Sci. V. 255. — Long. 

 1 J lin. Elongate cylindrical, piceous, antennae and feet ferruginous yellow ; ely- 

 tra yellow in front, black behind, the latter color commonly extending for- 

 wards along the suture ; prothorax long, tuberculate and slightly hairy in front ; 

 elytra very finely punctate-striate, glabrous and shining, at the tip obliquely 

 truncate, and thickly clothed with yellow silky hairs j the margin of the de- 

 clivity is acute, and there is a small tubercle near the suture. [Found through- 

 out the Atlantic States. — Leg.] 



C. [mali.^ TbwiicMS ynali Fitch, Noxious Insects of New York, ii, No. 5.] — Long. 

 1 lin. Brown, base of thorax and elytra paler; antennse and feet ferruginous 

 yellow; very similar to C fasciatus, but smaller, with the rows of punctures 

 of the elytra scarcely visible ; the oblique truncation of the tip is glabrous, and 

 there are two small teeth near the suture. — Maryland. [Also found in the 

 Southern States and in Canada. — Leg.] 



B. — Prothorax longer tlian wide ; antennal club not fringed witli 

 hairs ; anterior femora not toothed at tip ; front clothed more or less 

 thickly with silky hair. 



C. [materiarius.^rowiz'cji.s mat. Fitch, Noxious Ins. New York, ii, No. 246.]— 

 Long, li lin. Elongate cylindrical, shining brown, base of elytra paler; head 

 and under surface black; antennae and feet yellow; front somewhat impressed, 

 thickly punctured, hairy ; prothorax long, finely tuberculate in front, smooth 

 behind; elytraVery smooth, with scarcely visible rows of punctures, rounded 

 behind, without tubercles, thinly clothed with short yellow hairs. — North Caro- 

 lina. [Also found in the Northern States .and in Canada. — Leg.] 



C. comatus Zimm. — Long. 3 lin. Brown, antennae and feet yellow; protho- 

 rax roughly t\ibercu]ate in front, ornamented each side with a patch of thick 

 yellow silky hair ; elytra very finely but distinctly punctate-striate, obtusely 

 rounded at tip and without tubercles. South Carolina. 



C. minutissimus Zimm. — Long. 3 lin. Cylindrical, slender, black, antennae 

 and feet pale brown ; front clothed with long yellow hairs ; prothorax roughly 

 tuberculate in front, smooth and shining behind; elytra clothed with a fine 

 short gray pubescence ; behind obtusely rounded, without tubercles. — Carolina. 

 [Also found in the Northern States; I have received this species from Dr. Mel- 

 sheiiner as Tomicus pusillus Harris, Trans. Nat. Hist. Soc. Hartford, 83, and it 

 certainly agrees with the description better than any other species known to 

 nie. The one referred by Dr. Fitch, Noxious Insects of New York, ii. No. 245 

 to Harris' species seems to be quite different, by the prolonged acute suture and 

 may belong to the group Piti/ophthorus, with the European ramulorum, to which 

 he compares it ; the description of Dr. Fitch otherwise corresponds with the 

 next species. — Leg.] 



C. puUus Zimm. — Long. 1 lin. Somewhat smaller and narrower than the 

 European C. chalcographus, but very similar to it; dark brown, antennte and 

 feet ferruginous yellow; front scarcely hairy; prothorax roughly tuberculate 

 in front, punctured behind, with a faint smooth dorsal carina; elytra glabrous, 

 distinctly punctured, but not in rows since the intervals between the rows are 

 punctured as strongly as the rows themselves; along the suture there is a faint 

 longitudinal groove ; the tip is rounded, but the margin of the declivity is ele- 

 vated and armed with two or three slight spines. South Carolina.
