Texas (Austin). 



This is an interesting species, allied to naso, but having the 

 antennse of the male still more apical in insertion, and the pronotal 

 sculpture nearly as in fissunguis. A single specimen. 



C» integer n. sp. — ^Oblong-oval, moderately convex above, dull, black, the 

 elytra and legs witb a feeble piceous tinge ; pubescence of the elytra not very 

 dense, consisting of short recumbent hairs, ochreous or fulvous in color, nearly 

 evenly distributed and scarcely at all mottled, mixed with short sparse setae, 

 not paler or denser behind the middle, the pronotum sparsely setose. Head 

 densely and rather finely punctate, the yellowish pubescence not extending 

 beyond the front ; beak long, slender, arcuate, about one-half as long as the 

 elytra in the male, strongly sulcate, the antennae inserted beyond apical third. 

 Prothorax very nearly as long as wide, the sides broadly rounded anteriorly, 

 becoming parallel and nearly straight in basal three-fifths, finely, moderately 

 constricted just behind the apex> the latter not more than one-half as wide 

 as the base ; disk coarsely, extremely densely, unevenly and subconnuently 

 punctate, evenly convex and with a fine entire median carina. Elytra one-half 

 wider than the prothorax and not quite three times as long, two-fifths longer 

 than wide, the sides becoming subparallel in basal half; humeri right, widely 

 exposed but rounded ; disk with series of moderately large deep close-set 

 punctures, the alternate intervals with fine strongly-marked entire carinae. 

 Abdomen coarsely, very deeply and densely punctate. Legs long ; femora 

 moderately robust, subfusiform, obtusely and very feebly uni-dentate, the 

 toothed appearance caused principally by the abrupt and deep subapical 

 emargination ; tarsal claws divergent, strongly toothed. Length 6.0 mm. ; 

 width 2.9 mm. 



Arizona (Tucson). 



The single male represents a species allied to naso, but with the 

 pubescence of the elytra much sparser and not at all condensed or 

 whiter behind the middle, and the pronotal sculpture more than 

 twice as coarse, being fully as coarse as in geminatus. Both this 

 species and carinifer have the peculiar oblong-oval form and general 

 rostral structure of naso, and should evidently be associated with it. 



C. duplex n. sp. — Robust, suboval, strongly convex, blackish-piceous, 

 the elytra rufous ; vestiture of the anterior parts very sparse, in the form of 

 long stiff anteriorly directed setae, on the elytra of moderately dense, somewhat 

 uneven prostrate hairs, coarser denser and paler yellowish toward the humeri 

 and transversely behind the middle, also with long stiff erect setae. Head 

 densely punctate and with sparse subrecumbent yellow hairs, the front with 

 a deep median fovea ; eyes moderate, remotely separated ; beak moderately 

 thick, feebly, evenly arcuate, fully as long as the head and prothorax, very 

 deeply, longitudinally punctato-sulcate, strongly carinate along the middle ; 

 antennse inserted at apical third, the second funicular joint very long, about
