386 SUBFAMILY X. CURCULIONINJE. 



collections. Aside from the differences given in the key, it is 

 distinguished by the thorax being more convex, with sides more 

 rounded, its punctures, as well as those of intervals, deeper and 

 rounder, their sides less polygonal ; under surface more densely 

 scaly, size larger and both sexes shining black. 



586 (11,167). ODOXTOCORYXTTS SALEBROSUS Casey, 1892, 598. 



Oblong-oval, convex. Black, dull; legs and antennae more or less 

 reddish-brown; vestiture above variable, consisting of either slender 

 sparse, scale-like hairs, or robust, oval, conspicuous whitish scales; those 

 of under surface broad and very dense. Beak and antenna? much as in 

 denticornis. Thorax less convex, sides nearly parallel on basal two- 

 thirds, then broadly rounded and converging to apex; disc densely and 

 finely punctate. Elytral striae deep, rather coarse; intervals with con- 

 fused coarse punctures. Basal joint of club of male as in denticornis. 

 Length 2.94.7 mm. 



Throughout Indiana, but scarce; June 3 July 15. Orange, 

 X. J., April. Dunedin, Fla., Apr. 4 Dec. 3 ; swept from huckle- 

 berry. Ranges from New York to Colorado, south to Florida and 

 Texas. Collected on Aster, Apr. 28 in Louisiana; on Aselepias. 

 May 25, and on AcliUlca Jatuilosa Nutt, May 24, in Texas and 

 Oklahoma. (Pierce.} Closely allied except in size to (lei)tieornix. 

 and will probably prove to be but a dwarf variety of that species. 

 Casey in his description states that the disc of thorax is "devoid 

 of impunctate line,'' but a specimen determined by him in the 

 Leng collection shows such a line very distinctly. 



586 (11,167). OnoxTocoRYNUS SALEBROSUS Casey, 1892, 598. 



Oblong, oval, robust. Dull black, antenna?, tibia? and tarsi reddish- 

 brown; above and beneath thickly clothed with large oblong-oval yellow- 

 ish scales, those on the intervals arranged in two or three irregular 

 rows and nearly concealing the sculpture. Beak slightly longer than head 

 and thorax, deeply, coarsely and rugosely punctate, male; one-third longer, 

 more strongly curved, finely and sparsely punctate, female. Thorax two- 

 thirds wider than long, sides broadly rounded, feebly constricted near 

 apex; disc finely and very densely punctate, each puncture bearing a 

 narrow yellowish prostrate scale. Elytra oblong, slightly wider and two- 

 thirds longer than thorax; sides distinctly converging from base to near 

 apex; stria? coarse, deep; intervals flat, twice as wide as the grooves, coarse- 

 ly and rugosely punctate. Length 3.8 4.3 mm. 



Brown, Orange and Harrison counties, Ind., scarce; June 11 

 21. Described from Arkansas. The large yellowish scales and 

 long robust club easily separate this species from sale-brosns.

Oval, subrhomboidal, convex. Black, antennal funicle gradually 

 reddish toward apex; scales of upper surface whitish, sparse, closer
