AMERICAN COLEOPTKRA. 447 



oil the base of the second interspaces, thus foriiiint; an interrupted line from the 

 end of the oblique spot on tlie sixth to the basal spot on the second interspace, a 

 short sutural line and a less distinct post-median fascia of white, piliform scales: 

 anterior coxae narrowly separated, femora and tibise slender, former mutic, the 

 latter widened towards the apex, first joint of tarsi a little elongate, lobes of 

 third rather long, fourth projecting less than the length of the third joint, claws 

 very small, simple. Length 2.0-2.25 mm. ; 0.08 0.09 inch. 



% . Fovea of last ventral segment transverse, oval, sharply limited, middle 

 and posterior tibise distinctly unguiculate at the apex. 



Hab. — District of Columbia, Virginia. Nat. Mus. and Mr. Ulke's 

 collection. Two males. 



This species is not unlike C. obUquui^ Lee, from wliich it differs 

 by its 7-jointed antennal funicle and mutic femora. The two speci- 

 mens differ considerable in appearance, the specimen in the National 

 Museum is more densely scaly, has the scaly vestiture better preserved 

 and the spots on the second and fourth elytral interspaces large and 

 conspicuous, while the post-median band is evident only on the sides. 

 Mr. Ulke's specimen has the oblique spot quite conspicuous and sur- 

 rounded by a subglabrous space and the post-median fascia quite 

 distinct, the spot on the fourth interspace is quite small. It seems 

 that the yellowish scales are more easily abraded than the white 

 scales, the former being almost absent in Mr. Ulke's specimens. 



C\ persiniilis n. sp. PI. xiv, fig. 31a. — Oblong, black, antenna; and legs 

 p.iler, densely clothed beneath with grayish white scales, above with coai-se, 

 grayish, squamiform pubescence intermixed with white scales of various sizes. 

 Beak a trifie longer than the prothorax ( 9 ). cylindric^xl, curved, glabrous, re- 

 motely punctured, finely striate towards and scaly at the base: antennre piceous, 

 slender, inserted two-fifths from the base ( 9 )< 'ii"st two joints of funicle elongate, 

 3-4 short, equal, outer joints scarcely wider, club elliptic, acuminate. Head 

 densely i)unctured and scaly, front flattened ; prothorax a little wider than long, 

 narrowed from the base, broadly rounded on its posterior two-thirds, broadly and 

 deeply constricted behind the apical margin, the latter elevated, entire, a trans- 

 verse ridge extending from the lateral tubercles towards the median line and 

 limiting posteriorly a broad, transvei-se groove which occupies the anterior half 

 of the prothorax, dorsal channel widened anteriorly, ocular lobes prominent, 

 base feebly emarginate each side, disc closely punctured, punctures larger on the 

 sides, the latter more densely clothed with pale scales; scutel small, distinct. 

 Elytra less than one-fourth wider at the base than the prothorax, sides nearly 

 straight and gradually narrowed for three-fourths their length, then oblicjuely 

 narrowed to the apex, stria; impressed, jiunctured, more or less concealed by the 

 sciiles, interspaces slightly convex, each with a row of very small, acute granules, 

 which become larger and more evident on the declivity, a not well defined spot 

 behind the scutellum of white scales; femora feebly clavate, piceous, uiutic, tibise 

 and tarsi rufo-piceous, the former subi)arallel. the latter slender, first and second 

 joints elongate, compressed, third broadly bilobed, fourth long and slender, pro-
