Guide to the study of insects, and a treatise on those injurious and beneficial to crops: for the use of colleges, farm-schools, and agriculturists . Fig. CEKAJIBYCID^E. 499 of girdling is unknown to the insect, whose life is too shortto foresee the necessities of its progeny during the succeedingseason. This insect maybe seen in Pennsylvania during the twolast weeks in August and the first week in September feedingupon the bark of the tender branches of the young sexes are rather rare, particularly the male, which is rathersmaller than the female, but with longer antenna?. The femalemakes perforations in the branches of the tree upon which shelives (which are from half an inch to less than a quarter of aninch thick), in which she deposits her eggs ; she then proceedsto gnaw a groove of about a tenth of an inch wide and deeparound the branch, and below the place where the eggs aredeposited, so that the exterior portion dies and the larva feedsupon the dead wood and food which is essential to manyinsects, although but few have the means of providing it forthemselves or their progeny by an instinct so remarkable.
