312 CURCULIONID^. 



[LeConte. 



strongly curved, frontal constriction deep. Protliorax wider than long, 

 narrowed from the base, sides oblique, scarcely rounded, feebly constricted 

 near the tip; surface densely punctured, scales directed transversely; scu- 

 tellar lobe long. Elytra scarcely wider than the protliorax, gradually nar- 

 rowed from the humeri, tips separately very slightly rounded, pj-gidium 

 exposed at tip; striae deep, punctured, interspaces flat, densely punctured, 

 scales in about three nearly regular series on each interspace. Beneath 

 densely punctured; prosternum transversely impressed, slightly concave 

 near the tip and also each side; moderately wide between the coxae; sharply 

 emarginate in front of the mesosternum; metathoraic side pieces wide; fifth 

 ventral segment scarcely longer than fourth. Funicle of antennae with the 

 first joint as long as the three following united; second not longer than 

 third. Length 2.5 mm. ; .10 inch. 



(^. Prosternum with a long, nearly straight horn in front of each coxa; 

 varies with the horns verj- short. Beak punctured and striate. 



9- Prosternum without horns. Beak sometimes punctured and striate, 

 as in the (f; sometimes feebly punctured and not striale.

Georgia and Texas; two specimens. Similar in size and form to the pre- 

 ceding, but tiie scales are more hair-like, and are more densely i)laced on 

 the sides of the prothorax. The stri;e of the elytra are finer, and the inter- 

 spaces consequently wider. The front coxae are moderately distant, and 

 the prosternum is concave at the middle, but not impressed at the sides; 

 th'j hind margin is very sliglitly rounded, not emarginate; the metathoracic 

 side pieces are wide, and the fifth ventral is scarcely longer than the fourth. 

 Funicle of antennae rather stout, first join* as long as the three following; 

 s 'cond scarcely longer than the third. Prosternum without horns in the (^. 

 Length 2.5 mm. ; .10 inch.

Tejon, California ; one female ; Mr. Xantus. Enterely similar in form 

 and size to the two preceding, but the scales are oval, and of two colors, 

 sulphur-yellow and black; the first color, though paler, prevailing on the 

 under surface; and forming also three broad vi tte on the prothorax. Scu- 

 tellum black. Elytra with the whole of the second interspace; the third, 

 except f)r the basal fourth; the fourth for the basal fifth; the sixth for the 

 anterior half; the seventh and eighth for the posterior two-thirds covered 

 with yellow scales, arranged in two or three rows on each interspace; striae 

 rather deep, punctured Prosternum convex, transversely impressed, as 

 usu'il, but notconcive; front cox B widely separated. Metathoracic side- 

 piec 's wide; abdomen convex; fifth ventral not longer than fourtli. Funicle 

 of antennae rather slender; second joint a li.tle longer than the third, 

 L "ngth 2.5 mm.; .10 inch.
