256 CURCU LEONIDS. 



[LeC'onte. 



10. C. oblongus, n. sp. 



Oblong elongate, black, thickly clothed with brown and gray scales irregu- 

 larly intermixed; back of head, and some indistinct lines upon prothorax 

 pale. Beak as long as prothorax, rather more slender than usual, naked, 

 dark-brown, punctured. Antenna brown; second joint of funicle nearly 

 as long as the first, 3-7 equal in length, gradually broader and rounded. 

 Prothorax wider than long, deeply and densely punctured, not carinate, 

 narrowed from the base, rounded on the sides, moderately constricted near 

 the tip, base each side truncate, median lobe distinct. Scutellum 

 very distinct, clothed with brown scales. Elytra one-fourth wider than 

 the prothorax, humeri rounded, not prominent; sides parallel, scarcely per- 

 ceptibly sinuate, then obliquely rounded to the tip; strire composed of ap- 

 proximate punctures, fifth with a narrow blackish spot behind the middle, 

 interspaces convex, equal. Thighs with a distinct obtuse tooth, and front 

 pair with an additional small denticle; beneath coarsely and densely punc- 

 tured, thinly clothed with large, pale scales. Length 6 mm. ; .23 inch. 



Georgia and Texas, two specimens. There are no bristles intermixed 

 with the scales. 



11. C. ferratus Say, Cure. 28: ed. Lee. i. 296; Boh., Sch. Cure. iv. 143. 

 Middle, Southern and Wlstern States. Easily known by the small size, 



stout funicle, and alternate elytral interspaces ornamented with pale 

 spots. The scales are intermixed with very short bristles. Say has des- 

 cribed the elytra as striate, without punctures, but the description of Boh- 

 eman is quite correct; the stride are as strongly punctured as is usual in the 

 genus, and when the scales are removed, are seen to be quite deep, with 

 convex interspaces. Length 3.2 mm. ; .125 inch. 



ZASCELIS n. g. 



The species of this genus are rather elongate and depressed, coarsely 

 sculptured, pubescent, and sometimes also scaly. The beak is long, slen- 

 der, slightly curved, cylindrical, and extends almost to the metasternum. 

 The antennae vary with the species, the club being sericeous, elongate in 

 one species, and scarcely annulated, while in the others it is oval and an- 

 nulated. The ventral sutures are deep, and the first is slightly sinuate; the 

 first ventral segment is longer than the second, which is equal to the third; 

 fourth and fifth are also equal in length. The mesosternum is elongate, 

 and deeply excavated almost to the base. The thighs are rather stout, 

 sinned beneath with a small tooth, tibiae broad, compressed, with a row of 

 teeth along the outer margin of the middle and hind pairs, which becomes 

 indistinct in some species. 



This genus seems to be allied to Cnemargus and Enteles, but differs (ac- 

 cording to description) by the toothed tibiae; this character is an extremely 

 rare one in Curculionidcv, and I find it mentioned by Lacordaire only in 

 one instance: in Cnemidophorus which is allied to Magdalis. 



The species may be distinguished as follows:
