. Annual report of the Trustees of the State Museum of Natural History for the year ... Science; Museums. Report of the State Entomologist. 265 occurring in the peacli, were emerging- in my office June sixth, from sections of the trunk of a young peach tree, received from Mr. G. W. Duvall, from near Annapolis, Md. The tree had, it was believed, been killed by the insect the preceding year. The main galleries of the beetles, are usually run transversely across the trunk, but at times are inclined at various angles up to forty-five degrees. The longest are about one inch and a half in length, by one-twentieth of an inch broad, and show plainly the row of niches on each side excavated for the reception of the eggs, and from which the galleries of the young larvee proceed. These galleries are an inch and a half, or more, in length. Those central on the main gallery, extend at right angles to it, while those on each side thereof S^iverge at such angles as their greater breadth, consequent on the increasing size of the larvse, necessitate. The galleries are not strictly rectilinear, but are somewhat waved. Dr. Harris, Dr. Fitch, and subsequent writers mention this beetle as occurring under elm bark. I have never found it in such a situation. Mr. Schwarz gives as his experience, which in the Scolytidce has been so extensive as to deserve being accepted as authoritative, that it does not under elm bark. He thinks that it has been confounded with Hylesmus opaculus, which is rather common under such conditions and which resembles it so closely that without examination of the anten- nal structure the two can hardly be separated {Proceed.

T., in sending a living specimen of this " water- bug " for name, on February twenty-second, states that he only knows the insect as seen during the winter under the ice of a certain fresh-water pond near Greenport, on the Long
