Goleopterological Notices, VII. 67 5 



deep brown in tint and inconspicuous, those of the pronotum large, rounded 

 and brown, each filling one of the coarse punctures. Head and basal parts of 

 the beak clothed with white scales, except the deep frontal depression between 

 the diverging upper parts of the eyes, which is clothed with slender brown 

 scales ; eyes separated at lower third by fully }^ of their own width. Prothorax 

 slightly shorter than wide, the sides subparallel, broadly sinuate at the middle 

 and slightly narrowed at base, oblique and sinuate at apex, the latter broad 

 and very feebly sinuate ; punctures coarse, deep and contiguous. Elytra fully 

 % longer than wide, f^ longer than the prothorax and nearly % wider, the 

 humeral callus rather prominent ; subapical umbones moderate ; striae abruptly 

 defined, coarsely punctate at the bottom, not quite as wide as the flat intervals. 

 Legs moderate, the femora densely clothed with blackish scales, with a large 

 spot of white above at the base and another, smaller, near the apex. Length 

 2.6-2.9 mm. ; width 1.1-1.25 mm.

Allied to quercus, but differing in its less obese form and in pe- 

 culiarities of ornamentation mentioned in the table, also in the 

 much larger and more rounded scales of the pronotum. Of quer- 

 cus I have specimens from Illinois, Indiana and District of Co- 

 lumbia. 



C. cavifrons. — Stout, suboval, convex, deep black throughout, densely 

 clothed beneath and on the flanks of the prothorax, except anteriorly, with 

 large white scales, also on the median line of the pronotum at base and apex, 

 in the sutural region of the elytra to just behind the middle, where the offset 

 forming part of the posterior transverse series is oblique ; externally, there are 

 isolated spots of white forming the two vague, posteriorly arcuate series pre- 

 vailing throughout the genus ; pronotum elsewhere clothed with slender dark 

 squamules, the ground of the elytra similarly clothed with dark scales which 

 are narrow, oval and inconspicuous ; lower parts and extreme upper point of 

 the front and base of the beak clothed with white scales, the deep excavation 

 between the upper subsinuous inner margins of the eyes, and also the occiput, 

 in large part clothed with dark and inconspicuous squamules ; eyes separated 

 at lower third by distinctly less than % of their own width. Prothorax rel- 

 atively small, not as long as wide, the sides parallel, feebly sinuate at the 

 middle and obliquely sinuate at apex for a short distauce, the apex moderately 

 broadly subtruncate ; punctures moderately coarse and rather crowded, trans- 

 versely oval in form. Elytra with rather arcuate sides, fully % longer than 

 wide, nearly twice as long as the prothorax and fully % wider, the humeri 

 rather exposed, obliquely rounded ; subapical umbones large and conspicuous ; 

 strise not very coarse, abrupt, rather closely punctate along the bottom, very 

 much narrower than the flat intervals. Legs rather slender ; femora clothed 

 with dark squamules in apical half, with a white subapical spot. Length 

 2.5-2.9 mm. ; width 1.1-1.35 mm.
