[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. El3'tra scarcely wider than the prothorax, gradually nar- 

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

 exposed at tip; strise deep, punctured, interspaces tiat, 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 ver}- short. Beak punctured and 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 

 th? sides of the prothorax. The strise of the elj^tra 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; 

 Wv:' hind margin is very slightly rounded, not emarginate; the metatlioracic 

 side i^ieces are wide, and the fifth ventral is scarcely longer than the fourth. 

 Fimicle.of antennae rather stout, first joint as long as the three following; 

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

 Leng'h 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; tlie first color, though paler, prevailing on the 

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

 telliim 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 

 usuil, but not cone ive; front cox^ie widely sep arated. Metatlioracic side- 

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

 of antennae rather slender; second joint a little longer than the third, 

 L?ngth 2.5 mm.; .10 inch.
