1. C. scutellum-album Say, Cure. 21; ed, Lee. i, 287; Baridius scut. 

 Germ. Sch. Cure, iii, 730. 



An abundant species over the whole of the Atlantic district. Varies 

 considerably in size (3-4.7 mm.; .12-. 18 inch), the smallest specimens 

 occurring in all parts of the country; also in form, some of the smaller 

 specimens from Texas being less robust, with the sides of the prothorax 

 less rounded; also in vestiture, which is sometimes denser and yellowish, and 

 squamose upon the elytra, in specimens from Texas. The white scales of 

 the scutellum are not unfrequently removed by abrasion. The antennae 

 are stouter than in the following species, and the second joint of the funicle 

 of the antennae is distinctly longer than the third; the prosternum is deeply 

 transversely impressed, and is flattened behind the impression, but has no 

 trace of spines in either sex. The metasternal episterna are wide; the fifth 

 ventral is scarcely longer than the fourth. The anal segment is exposed in 

 the J\ and is slightly declivous. Of all the species in our fauna, this 

 makes the nearest approach to Baris.

New York to Florida and Louisiana. The vestiture is of narrow-pointed 

 brassy yellow scales, or coarse flattened hairs, on the prothorax they point 

 transversely towards the middle, which is slightly carinate; on the elytra 

 they form three nearly regular rows, upon each of the densely punctured
