312 CUKCULIONID^E. 



[LeConte. 



strongly curved, frontal constriction deep. Prothorax 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 prothorax, gradually nar- 

 rowed from the humeri, tips separately very slightly rounded, pygidium 

 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. 



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

 varies with the horns very short. Beak punctured and striate. 



9 Prosternum without horns. Beak sometimes punctured and striate, 

 as in the tf; sometimes feebly punctured and not striate.

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

 ceding, but the scales are more hair-like, and are more densely placed on 

 the sides of the prothorax. The strise of the elytra are finer, and the inter- 

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

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

 the hind margin is very slightly 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 joint as long as the three following; 

 a 'cond scarcely longer than the third. Prosternum without horns in the <$. 

 Length 2.5 mm. ; .10 inch.

Tejon, CalHoFma ; 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 tae on the prothorax. Scu- 

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

 except for 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 

 usual, but not concive; front COXB widely sep arated. Metathoracic side- 

 piec i s wide; abdomen convex; fifth ventral not longer than fourth. Funicle 

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

 Length 2.5 mm.; .10 inch.
