TIih female is provided with a straight awl-like ovipositor, nearly as long as her body with which she perforates the bark when depositing her eggs. " Th« worms from these eggs mine their burrows mostly lengthwise of the grain or fibre of the bark, and the channels which they excavate are so numerous and so filled with wor?n dust of the same color with the bark that it is difficult to trace them. The eggs are deposited the latter part of June, and the worms grow to their full size by the end of the season, and will be found during the winter and spring, lying in the inner layers of the bark, in a small oval flattened cavity which is usually at the larger end of the track which they have ; (Fitch). I have taken this species on the red oak, at Montreal, quite commonly. 6. The Apple Flat-headed Borer, Chrysobothris femor-at'a, (Fabr.) Order Oole- optera ; Family BuPRESTiDyE :— The larvae belonging to this family present an appearance somewhat resembling a tadpole, (Fig. 39, a. and c.) the second segment behind the head being enormously en-. Fig. 39. larged, while the remaining segments are much smaller. The species under consideration bores under the bark and in the sapwood of various trees, the apple and white oak in par- ticular. " The beetle (d) measures from four to five tenths of an inch in length " ; it is of a greenish black color, polished and shining, with the surface rough and uneven. The head and sometimes the thorax and the depressed portions of the elytra are of a dull coppery color. The elytra or wing-covers present a much more rough and unequal sur- face than any
