Consequently, when it does cut the last nervure, it is secure from falling, and can then travel along the leaf, carrying its tent on its back, as a snail does its shell.*. a. the caterpillar OOCtrpyinfl the space it has eaten between the cuticle of the leaf. 6, a portion of the upper cuticle, cut out for the formation of the tent, c, the tent nearly completed, d, the perfect tent, with the caterpillar protruding its head. We have just discovered (Nov. 4th, 1829), upon the nettle a tent of a very singular appearance, in consequence of the materials of which it is made. The caterpillar seems, indeed, to have proceeded ex- actly in the same manner as those which we have described, mining first between the two membranes of the leaf, and then uniting these and cutting out * J.
