tenor nmbones feeble; strise moderately coarse, the squamules of the strial 

 punctures narrow. Length 2.75 mm. ; width 1.25 mm. 



Southern Louisiana. Mr. Soltau. 



Allied to operculatus but smaller and relatively more obese, 

 with the punctures and scales sparser, the prothorax much 

 shorter and the eyes more narrowly separated. The scales of the 

 elytra are more conspicuous along the narrower intervals toward 

 base. The type is probably a male. 



C. floridanus. — Only very moderately stout, elongate-oval and convex, 

 deep black throughout, the tibiae and tarsi rufescent; scales relatively large, 

 white, dense in the condensed areas, pale brownish elsewhere, largely brownish 

 at each side of the median line of the pronotum ; white condensations of the 

 elytra linear and very indistinct, the arrangement scarcely discernible but con- 

 forming to the general type prevailing in the genus. Sead and basal parts of 

 the beak densely albido-squamose, the eyes at lower third separated by but 

 little more than }4 of their own width. Prothorax not quite as long as wide, 

 rather wider at apical third than at base, the sides feebly biarcuate, more con- 

 vergent and sinuate at the apex, which is feebly si nuato- truncate and scarcely 

 subtubulate ; punctures only moderately coarse and distinctly dense. Elytra 

 % longer than wide, % longer than the prothorax and scarcely more than }^ 

 wider; strise moderately coarse, punctured, the squamules rather stout. Length 

 2.0 mm. ; width 0.8 mm. 



Florida (Haw Creek). Hubbard and Schwarz. 



A small species, unusually narrow for this section of the genus 

 and allied to nanulus, but differing in the extremelj^ confused 

 ornamentation, smaller size and narrower form. Two specimens. 



Of nanulns, I have before me a large series from Iowa, Ohio, 

 Kentucky, North Carolina and Maryland ; it varies much in the 

 distinctness of the pale markings of the elytra, and, as usual, these 

 seem to be more sharply defined in the females than in the males. 

 The prothorax varies much in length and strength of the lateral 

 biarcuation, and it is possible that I may confound some distinct 

 species together, but the subject is too difficult to pronounce 

 upon in the absence of full and carefully collected series. 



C. frontalis.— Stout, suboval, moderately convex, deep black through- 

 out, the entire under surface and sides of the prothorax densely clothed with 

 large white scales, the flanks of the prothorax anteriorly more sparsely and 

 irregularly so ; white scales also evident on the median line of the pronotum 

 toward base, and, on the elytra, toward base and scutellum, in a short line on 

 the second interval behind the middle with an oblique posterior offset com- 

 posed of short lines on the third and fourth intervals, and in a few obscure 

 discal spots elsewhere ; the scales of the elytra are rather large but separated,
