C. pruinosus Boh. Schonh. Gen. Cure. VIII, 2, p. 13. 



Oval, convex, ferruginous, moderately shining. Rostrum sparsely 

 punctured in front, at base feebly longitudinally sulcate, above cariuate. 

 Head sparsely punctured, eyes moderately separated. Thorax nearly twice 

 as wide at base as long, sides gradually, arcuately wider to base, apex very 

 feebly constricted, base feebly sub-bisinuate, surface moderately convex, 

 median liue slightly smoother, coarsely and moderately densely punc- 

 tured, the punctures tending to strigosity at the sides. Scutellum small, 

 round, glabrous. Elytra oval, arcuately and but feebly narrowed toward 

 apex, surface deeply striate, striae with coarse punctures, intervals sub- 

 acutely convex. Body beneath ferruginous, sparsely punctured, abdomen 

 very much smoother. Legs ferruginous, femora dentate, anterior tibia? 

 with margin sinuous. Length .18-20 inch ; 4.5-5 mm. 



Boheman describes this species as having a slight aeneous tinge to the 

 surface, a character not possessed by any of the three specimens before 

 me. One of the specimens has the intervals of the elytra quite conspicu- 

 ously punctulate but does not otherwise differ. 



Occurs in Arizona and Peninsula of California. 



C. seneus Boh. Schonh. Gen. Cure. IV, p. 388. 



Black with faint bronze tinge. Rostrum sparsely punctulate, feebly 

 carinate. Head sparsely punctulate, eyes very narrowly separated. 

 Thorax one-fourth wider at base than long, anteriorly rather suddenly 

 narrowed, behind the constriction obtusely subangulate, thence feebly 

 arcuate and scarcely broader to base, the latter decidedly bisinuate, sur- 

 face convex, sparsely perforato-punctate. Scutellum small, glabrous. 

 Elytra oval, subparallel in front, toward apex arcuately narrowed, 

 convex, with rows of deeply impressed punctures, intervals extremely 

 minutely alutaceous and with a row of fine punctures each bearing a very 

 minute scale . Body beneath black, coarsely punctured, abdomen more 

 sparsely punctured, terminal segment more densely punctured. Legs 

 black, coarsely punctured, femora dentate, anterior tibiae narrower at 

 basal third. Length .20-. 22 inch ; 5-5.5 mm. 



Occurs in Georgia and Florida. Easily known by the coarsely perfor- 

 ato-punctate thorax. 



C. inaequicollis n. sp. 



Black with distinct aeneous tinge. Rostrum sparsely punctured at 

 tip, feebly sulcate at sides near base, above obtusely subcarinate. Head 

 sparsely punctured, eyes moderately distant with an impressed puncture 

 between them. Thorax one-fourth wider at base than long, sides in 

 front feebly sinuous and thence feebly arcuate to base, surface shining, 

 median line carinate in front, suddenly wider at middle, on each side a
