Arizona. 



The single specimen represents a distinct species, to be readily 

 known by the peculiar disposition of the vestiture, as well as by 

 the unusual length of the latter, also by the small size, dense punc- 

 tuation and exposed humeri. The elytral vestiture from the mar- 

 ginal vitta to the suture is almost even in distribution, but sparsely 

 speckled with extremely small and feeble denser aggregations of 

 hairs. The ocular lobes of the prothorax are very feebly developed, 

 and the vibrissae extremely short, coming far from attaining the 

 eyes. 



C. SllbcylindridlS. — Nearly evenly cylindrical and convex, Mack 

 throughout, the anterior portions rather dull, the elytra shining ; vestiture 

 very short, almost evenly distributed but rather sparse on the elytra except 

 near the lateral margin, where it becomes broadly dense both on the elytra 

 and prothorax. Head and beak not coarsely and moderately densely, deeply 

 punctate, the interspaces finely, deeply and very densely punctulate ; beak 

 short, robust, scarcely more than two-thirds as long as the prothorax, almost 

 completely glabrous, not carinate. Prothorax about as long as wide, the sides 

 feebly arcuate, more convergent anteriorly, the apex about three-fourths as 

 wide as the base, broadly bisinuate ; base obtusely cusped in the middle ; 

 ocular lobes short and wide, the vibrissse extremely short, widely distant from 

 the eyes ; disk somewhat coarsely, sparsely and unevenly punctate, the inter- 

 spaces finely but deeply and extremely densely punctulate and dull ; surface 

 almost completely glabrous except near the sides, not carinate, the basal 

 impression broad, extremely feeble and scarcely traceable. Scutellum not 

 distinct. Elytra quite distinctly more than twice as long as wide and but just 

 visibly wider than the prothorax ; sides parallel and almost straight, rather 

 broadly, obliquely arcuate behind, the apex rather narrowly parabolic and 

 minutely emarginate ; humeri obliquely, feebly rounded ; disk with unim- 

 pressed series of not very coarse, moderately distant punctures, the intervals 

 very finely but densely punctulate. Abdomen rather sparsely and unevenly 

 clothed, finely punctulate, also with slightly larger widely scattered punc- 

 tures. Legs rather short, somewhat sparsely punctured and pubescent, the 

 hind femora very much longer than the tibiae. Length 10.5 mm. ; width 

 3.8 mm. 



Florida. 



This species is closely allied to texanus but differs in its more 

 robust form, larger prothorax, the latter being more finely punc- 

 tured and much more nearly equal in width to the elytra, in its 

 uncompressed beak, more developed ocular lobes and much shorter 

 vibrissae, and in its shorter and less pubiform vestiture. 



In common with nearly all of the robust Cleonini, each elytral
