Fifth report of the United States Entomological Commission, being a revised and enlarged edition of Bulletin no7, on insects injurious to forest and shade trees . e unpleasant to the nostrils, for even the deatf bodies of half a dozen sent me,although occupying a place, as I am writing upon an open piazza, at a distance ofseveral yards from me, and after having been exposed to the air throughout thenight, have rendered their vicinage quite intolerable to some of the unscientificmembers of my family who had been sitting with me. The beetle, although horrid in the eyes of the gentleman communicating it, is tothe entomologist, from its size, form, and ornamentation, a beautiful and attractivespecimen of the Coleoptera. The largest male before me (I have seen larger exam-ples) is inches long ( with legs extended), inches across the wing-covers,and of an inch in thickness of body. The shape of the female is nearly that ofthe common grapevine beetle, the Pelidnota punctata, but the male is armed anteri-orly with two black horns, a half-inch or more in length, the upper one being a hori- 552 FIFTH REPORT OF THE ENTOMOLOGICAL zontal projection of the front part of the thorax, and the lower curving upward fromthe crown of the head. Beneath the color is black, while the thorax and wing-covers are of a pale olive-brown, the latterdotted irregularly with black spots ofvarious sizes, of which some of thelargest are ocellated. The legs aresliining black, and are armed withhorns and spines. The grub which produces the beetlefortunately is not to be numberedamong our insect pests, as it only attacks, so far as my knowledge of itshabits extends, decaying trees. It isof not infrequent occurrence in theState from which these examples weresent, and in other Southern States. Itis rarely met with in Pennsylvania,and has never, I believe, been foundin the State of New York. Dr. Fitchincludes the species among those affect-ing the cherry tree. The beetles feedup
