between and above the eyes, diameter of head across eyes over 

 one third greater than greatest breadth of rostrum. Rostrum 

 less than half the length of thorax, basal portion shorter than the 

 apical, broader than long and with straight sides, apical portion 

 but slightly dilated and wider than basal, much broader than long. 

 Joints of funicle of antennae very transverse and but gradually 

 increasing in width outwards, outermost joint more than one half 

 width of club. 



Prothorax oblong, much longer than wide, base bisinuate, sides 

 narrowed at base, thence arcuate to near apex where slightly 

 constricted, surface moderately coarsely and closely punctured, 

 disc at center frequently impunctured, slightly depressed behind 

 on each side of median line. 



Elytra elongate, parallel, somewhat narrower than the thorax, 

 deeply striate, striae seriately punctured, more coarsely basally, 

 intervals narrow, flat at apex, finely uniseriately punctulate. 



Body beneath shining, coarsely and on the thorax densely 

 punctured. 



Length 4-5 mm., breadth .80 mm. 



Occurs from New York south to the Gulf States where more 

 common, Missouri and through Mexico to Guatemala (Cham- 

 pion). This species, because of its broad thorax and almost un- 

 dilated rostrum at apex could only be confused with one other 

 species in our fauna, C. crenatus, Horn. It difTers from this by 

 having a more evenly rounded thorax and less carinate elytral 

 intervals in addition to the differential characters given under C. 

 crenatus. This is sometimes confused with C. concinniis Boh. 

 but is readily separated by the rostral characters. C. corticola 

 Say has been found under dead oak bark in New Jersey (H. W. 

 Wenzel) and under dead pine bark at Tybee Island, Ga. (H. W. 

 Wenzel). The normal food trees, I believe, are pines.
