Like many other hiber- nating insects, they take shelter under rubbish, and thus afford another argument for clearing up and burning all garden refuse in the autumn. The Parsnip Borer (Depressaria kcracUana, De Geer) is an old enemy, though not a very common one, of the second years' growth of parsnips, both cultivated and wild. This year it proved injurious to some plants in the College garden. The full-grown caterpillar is about three-quarters of an inch in length, of a dirty green colour above and yellowish on the sides and beneath, with a number of shining black warts on nearly all the seg- ments. The young larvse first attack the large umbels of flowers, covering them with a web, whi-ch is rendered very unsightly with masses of excre- ment. When the flowers have been all devoured, they burrow into the hollow stems, usually entering at the axils of the leaves and there feed upon the soft, white lining. If, however, there should be young parsnip plants near by, some of the larvae are apt to attack them and eat up the tender foliage. By the middle of July they begin to turn into the chrysalis state and the small moths appear in August after a fortnight spent as pupae. This year the first moths in captivity came out on August 15th, but we have sometimes had them as early as the 1st of the month. The moths are dull gray, varied with black scales and blotches, and have a flattened abdomen with projecting scales at the sides. They have a habit, like some others of the genus, of coming into houses and secreting themselves behind curtains and, in garments, and are consequently mistaken for clothes moths. A full description of the insect in all its stages is given in the Canadian Entomo- logist, vol II., pp. 1-4, 1870. The only remedy for the attack seems to be the cutting off and burning all the infested
