A Moth that bores for its Food.—The order of Lepidoptera, which includes moths and butterflies, is almost universally characterized as possessing a flexible trunk, by means of which the insects suck up the nectar of flowers. Indeed, the possession of a flexible trunk is commonly regarded as one of the distinguishing characteristics of this order. A few years ago, however, a French botanist, M. Thozet, then residing in Australia, discovered a moth (Ophideres fullonica) which possessed a trunk so rigid as to be able to pierce the rinds of oranges and suck their juice. Another Australian observer having since called attention to the depredations of this moth, M. J. Künckel was led to examine the trunks of Ophideres which had been sent to him from Australia by M. Thozet. This trunk he declares to be a perfect instrument, and says that it would be an excellent model for the making of new tools to be employed in boring holes in various materials. It resembles the barbed lance, the gimlet, and the rasp, and hence can pierce, bore, and tear, at the same time allowing liquids to pass without impediment by the internal canal. The two applied maxillæ constituting the organ terminate in a sharp triangu-
