Enaphalodes atomarius (Drury) . New larval host

record.

JV found larvae of this species to be common in the base of fire-killed, young Q. alba at NJ: Burlington Co., Wharton State Forest. The habits somewhat resembled those of C. nobilis . The larvae bored into the base of the trunk and into the roots, constructing a pupal cell just above the ground, with a large, oval exit hole packed with fibrous frass. Larvae did not cut the exit hole all the way through the bark, as in the case of C. nobilis ; the bark had to be removed to find the plugged holes. Additionally, the long, empty prepupal burrow characteristic of C. nobilis was not present. Emergence holes were parallel with the grain, in contrast to emergence holes from E. atomarius seen on mature Quercus stellata Wangenh. from TX: Wise Co. These emergence holes had the longer axis transverse with the grain or slightly sideways and resembled exit holes of large Buprestidae .
