XXXvi, '25 ENTOMOLOGICAL NEWS' 139 Notes on Gerambycidae (Coleoptera). By A. B. Champlain, H. B. Kirk and J. N. Knull, Pennsylvania Bureau of Plant Industry. (Continued from page 109.) Xylotreciilts aceris Fisher — This species was found infest-ing red maple (Acer ruhrum) , silver maple (Acer saccliarinum)-and sugar maple (Acer saccJiaruni). The larval workings cause galls, usually after the species has emerged, on the smooth trunks and branches of the infested trees. Often stems four inches in diameter are attacked. This species, unlike the preceding, does not girdle branches, but mines the heart wood to such an extent that the part above the injury is often broken off by the wind. Several adults will often emerge from one infested area. X|vLOTRECHus COLON US Fab. — Adults were reared May 22, from dead hemlock (Tsuga canadensis) log collected at Monte-bello, Pennsylvania. Clytoleptus tristis Csy. — This is merely a black form of C. albofasciatus Lap., and all color gradations of intermediate forms may be found. Many of these forms have been reared from the same infested grape stem in our cages, and we have observed them mating. It therefore seems quite logical to con-sider C. tristis Csy. a synonym of C. albofasciatus Lap. Clytus marginicollis Cast. — An adult of this species was collected at Piseguit Brook, eighteen miles south of Bathurst, New Brunswick, on June 24. Cyrtophorus verrucosus Oliv. — Adults were reared from dead blue beech (Carpinus caroliniana) and redbud (Cercis canadensis) collected in the vicinity of Harrisburg, Pennsyl-vania. Purpuricenus axillaris Hald. — This species was found doing considerable damage to the lower branches of swamp white oak (Quercus bicolor) near Hummelstown, Pennsylvania, branches over two inches in diameter often being pruned. One egg seems to be laid to a branch, and as the larva works, down toward the trunk of the tree it mines through the heart-, wood of the branch and branchlets as it goes, often pruning the
