252 CURCULIONID^. [LeConte. 



lured, carinate ; disc with three conspicuous tufts of bristles, and two 

 smaller ones near the front margin ; others scattered singly ; scales brown, 

 with three narrow indistinct lines of paler ; base squarely truncate each 

 side, prolonged into a distinct angle at the scutellum, which is black. 

 Elytra one-third wider at base than the prothorax, humeri rounded, promi- 

 nent, sides not dilated, but parallel, and then gradually narrowed behind, 

 clothed mostly with pale-brown scales, darker at the base and tip, and with 

 a broad middle band sometimes indistinct; stri* fine, punctured, third, 

 fifth and seventh interspaces more elevated ; the third and fifth appear 

 interrupted on account of crests of erect blackish bristles ; of these there 

 are three long ones on the third and three or four small ones on the fifth ; 

 also a few small bunches on the second interspace. Beneath clothed with 

 pale-brown scales, deeply and densely punctured ; thighs slender, not, or 

 obsoletely toothed; tibiae straight, not augulated at base as in C. 2)(i)-oehii,s 

 and bisignatxts. Length 5.5 mm. ; .22 inch. 



Southern and Western States. So far as the meagre description given 

 l\v Say goes, this species agrees well with his C. obliquus, but as Bohcman 

 and Say agree in stating that that name belongs to the species called I)}- the 

 former C. umhrosus, I do not feel at liberty to apply it to the present one, 

 for which I have adopted the Catalogue name of Dejean. If our founa had 

 more representatives of this genus, I would separate this as a distinct divis- 

 ion, differing from the pi-eceding, not only by the tibiae and stouter beak, 

 but by the ninth elytral interspace being not elevated, and by the post ■ 

 ocular prothoracic lobes being more prominent. 



Division A — a**. 



The single species repi'eseuting this division in our fauna is of rather 

 large size, more elongate, and less Conotrachelus-\\V.(i than the species of 

 the preceding division, from which it differs chiefly by the thighs being 

 deeply sinuate beneath near the outer end, and by the two denticles being 

 near together. The beak is stouter than in C. paroeJius, but hardly more 

 so than in C. fuscatus, carinate and striate at base; the antenn* are inserted 

 about two-fifths from the end; the funicle is slender; second joint as long as 

 the first, the others gradually shorter; club not perceptibly annulated. Pro- 

 tliorax rounded on the sides, strongly narrowed in front, and feebl}' con- 

 stricted, postocular lobes not very distinct; base squarely truncate each side, 

 prolonged into a distinct angle at the scutellum. Elytra one-third wider at 

 base than the prothonjx, nearly parallel on the sides, then narrowed to the 

 tip, humeri rounded, less prominent than in the first division; striaj com- 

 posed of large punctures; third, fifth, and seventh interspaces slightly 

 elevated. The ventral segments are very coarsely punctured, and the 

 fifth in the only perfect specimen before me has a very deep circular 

 impression, probably sexual, and indicating the (j^. The thighs are slender, 

 with two small approximate teeth, then deeply sinuate near the tip; the 

 tibiae are straight, and rather strongly mucronate at tip, suddenly bent at 

 base near the knee; tarsi as in the first division.
