Pa., Hamilton; Iowa City, Iowa, Wickham). It has been found 

 beneath the bark of various broad-leaved trees as the butternut 

 (Granley), white walnut (Hamilton and Hopkins) and poplar 

 (J. B. Smith). It has als/O been secured from beneath dead pine 

 bark at Da Costa, N. J. (H. W, Wenzel) but I consider this not 

 a normal food tree. 



The species is best recognized, aside from the characters given 

 in the table, by its very black shining appearance. It closely re- 

 sembles C. subareatus Boh. but can be told from that by its broader 

 thorax, sHghtly more prominent eyes and shorter basal portion of 

 rostrum. Its food habits appear to be also similar to those of its 

 closest ally.

 Proc. Am. Phil. Soc, XIII, 2 Z, p. 438. 



Black, shining. Head quite smooth except laterally back of 

 eyes where very finely and sparsely punctured, rostrum moderately 

 coarsely and closely punctured at sides and less coarsely and 

 closely above. Eyes moderately and but very slightly protruding 

 beyond sides of head, diameter of head across eyes slightly greater 

 than dilated portion of rostrum. Sides of head gradually con- 

 vergent to base of rostrum. Rostrum as long as one half of the 

 thorax, but very slightly arcuate, basal portion longer than the 

 apical, parallel for first half then gradually increasing in width to 

 apical portion which is one third broader than its neck and quad- 

 rangularly dilated. Joints of funicle of antennae only gradually 

 increasing in width outwards, the outermost joint about one half 

 the width of club. 



Prothorax slightly longer than broad, apex rather suddenly 

 narrowed, base feebly bi-sinuate and but slightly impressed on 

 each side of middle, sides almost parallel at middle or but slightly 

 arcuate, basal angles rounded, surface flattened, unequally punc- 

 tured, the punctures at sides moderate below and finer above and 

 quite coarse and deep in median area, particularly basally, though 

 always well spaced. At base, the basal rudiment of a crista is 

 evident. 



Elytra but slightly wider than thorax, striate, striae moderately 

 coarsely and serrately punctured, intervals convex, very minutely 

 uniseriately punctured.
