XLI, '30 ] ENTOMOLOGICAL NEWS 101 Notes on Coleoptera No. 2. By J. N. KNULL, Pennsylvania Bureau of Plant Industry. (Continued from page 86.) ANOPLODERA MUTABILIS Newn. Reared from partly decayed wood of alder (Alnus nujom), large-toothed aspen (Populns grandidentata) and tulip poplar (Liriodcndron tulipifcra) col-lected in Clark's Valley. A. PROXIMA Say. Reared from the dead decayed wood on the inside of a hollow sour gum (Nyssa syk'atica) collected at Hummelstown, Pennsylvania. MOLORCHUS BIMACULATUS Say. Adults were reared from dead witch hazel (Hainaniclis rinjiniana) collected at Rock-ville, Pennsylvania. AIOLORCHUS BIMACULATUS CClti 11CW Subspecies. A Molorchus was found breeding in hackberry (Celtis occi-d entails) which seems to differ materially from the specimens of Molorchus bimacnlatus collected and reared from other hosts in the same vicinity. The adults are much larger in size than those reared from many other hosts, although the branches in which these were breeding were no larger. The adults vary in length from 8 to 11.5 mm. As compared with Molorchus buna cul a tits, the antennae are relatively longer in the type male, pronotum longer and more nearly cylindrical, apices of elytra more broadly rounded, punc-tures of pronotum and elytra much finer, pubescence of entire insect longer and more dense. Length 11 mm., width 2.5 mm. Described from a series in the collection of the writer which were chopped from the sapwood of dead hackberry (Celtis occidcntalis) branches and one specimen from the sapwood of dead redbud (Cercis canadcnsis) collected at Hummelstown, Pennsylvania, in December. Type in the writer's collection. The adults mature in the fall and pass the winter in their pupal cells. PHYSOCNEMUM VIOLACEIPENNE Ham. This species was reared from dead white oak (Oucrcits alba) branches from an inch to two inches in diameter collected in Clark s Valley. The dead branches were attached to the living trees and had died the previous spring. The larvae work beneath the bark parallel with the grain and pupate in the sapwood.
