vittfe where the vestiture is white and dense. Head finely, the beak more 

 coarsely and both confusedly punctate and subrugulose ; beak rather long, 

 subeqnal iu length to the prothorax, distinctly tumid or broadly subcarinate 

 along the middle, the tumid line more sparsely punctate and terminating 

 behind at a feeble transverse impression between the eyes. Prothorax about 

 as long as wide, the apex broadly arcuate, much narrower than the base, the 

 latter broadly, strongly cusped in the middle and but feebly oblique thence 

 to the basal angles ; sides feebly convergent and almost straight from the base 

 nearly to the apex, then rather more strongly convergent and just visibly 

 sinuate ; disk coarsely, not very densely punctate, a rather broad median line 

 almost completely impunctate, the interspaces finely, rather sparsely punctu- 

 late, the surface feebly convex except at the basal cusp where it is moderately 

 impressed, also tumid or subcarinate along the middle in apical half, the ves- 

 titure forming a dense marginal and a narrower sparser discal vitta on each 

 side. Elytra rather distinctly more than twice as long as wide and nearly one- 

 third wider than the prothorax ; sides parallel and nearly straight, becoming 

 strongly oblique and nearly straight in ai)ical third, the apex narrowly sub- 

 truncate, broadly rounded, and minutely emarginate in the middle; humeri 

 obliquely rounded to the thoracic base ; disk with series of rather coarse ap- 

 proximate punctures which become much finer toward apex where also the 

 series become distinctly'' impressed. Abdomen densely clothed with rather long 

 cinereous pubescence. Legs rather short and moderately robust, finely, deeply 

 but rather sparsely punctate and somewhat sparsely pubescent. Length 13.0 

 mm. ; width 4.5 mm. 



Arizona. 



This remarliably distinct and beautiful species is represented by 

 a single specimen, formerly a part of the Levette cabinet, and which 

 is without more definite indication of locality than that given above. 

 It is somewhat allied to the Mexican houcardi Chev., but the latter 

 has a white vitta between the seventh and eighth striae, while in 

 lecontei this interval is entirely nude, the marginal vitta being ab- 

 ruptly limited by the eighth stria and the lateral margin. 



C. lolbigerillllS. — Rather slender and convex, the integuments feebly 

 shining ; pubescence dense, cinereous, forming a broad discoidal anteriorly 

 constricted spot — which is narrowly denuded along the middle, and a mar- 

 ginal vitta on the pronotum, also denuded on the second, sixth and eighth 

 elytral intervals and less completely so on the seventh. Head rather strongly, 

 transversely impressed between the eyes, the beak rather long, feebly cari- 

 nate, subequal in length to the prothorax. Prothorax nearly as long as wide, 

 the apex broadly, feebly bisinuate, distinctly narrower than the base, the 

 latter strongly, angularly lobed in the middle; sides feebly convergent from 

 base to apex and nearly straight in the male, convergent and feebly sinuate 

 near the apex in the female ; ocular lobes long and prominent, extending to the 

 eyes, the vibrissas very short ; disk dull, coarsely, rather densely punctate,
