. Annual report of the Trustees of the State Museum of Natural History for the year ... Science; Museums. 168 Forty-first Rep out on the 8tate Museum. the action of winds or the vegetal changes that take place at the wounded part, soon falling to the groiind, the young larva escapes therefrom and enters the earth. That the food for an insect of the size of one indicated by the cuts made by its mandibles could not be furnished by the excised and soon dried tip of less than a half-dozen inches in length, is evident. It is probable that its food-siipply would be found among the roots of the plant. The Young Insect Seen. Of a large number of the tips which were dissected in the search for the insect, in a single one, only, was it discovered, as a minute, whitish, oval creature, apparently just from the Qgg, occupying place very near the point of excision. Its structural characters were too imperfectly developed to admit of its positive reference to any one of the orders, but it was believed to belong to the Hymenoptera. Other tips kept for several days in a moist condition, gave no further developments. How the Attack may be Determined. If its habits and food be such as above conjectured, there is but little chance of obtaining the insect by rearing it from the Qgg, unless with the aid of potted plants kept under observation within doors. A better method of ascertaining the author of this secret attack, would be, to detect it in its work, by seeking it with a lantern at night. Will those whose interest or curiosity may be awakened by the above account, bear in mind the character of the attack, and embrace any opportunitjr that may be offered in its recurrence to aid us in the effort to obtain the scientific name of the currant-stem girdler?
