Its larva bores in oak and chestnut wood. In CaUichroiivi the scutelluni is acute at the ti}i, the anterior coxal cavities are closed behind, and the jirothorax has a spine on each side. A common European species, C. moscliuta, of which the odor has been already alluded to, is al)out an inch long, bronze green with bluish green legs and antenna;. Its larva lives in willow. C. sjjlendi- dum, a red-bronze si)ecies from 1 to l.:25 inches long, has been found in the southern United States. longicorns of medium or large size, with rounded thorax, moderately long, spiny antenna?, coarsely ]junrtured eyes and often of clouded or rusty ajipearance on account of the tmequal distribu- tion of their pubescence. E. jMrallehan is one of the commoner species in the northeastern United States. It is about of an inch long, and of an ashy brown color. The larva is a common borer in oak, and according to Prof. A. S. Packard, "nniy lie recognized l)y the stout, thick thoracic feet, by the rather small jirothoracic segment compared with the two hinder ones, by the ab- sence of the ligula, by the large well-developed pal]ii and autennse, and liy the shape of the cal- ; I have found the larva of this sjiecies to be very injurious to the hickory in nortliern Connec- ticut, where it eats away the wood beneath the bark of twigs u
