(A/n-r .\ Of the female is moved rnpidly with a swinging motion Irom side to side, forming an irregular cell or pocket of an oval outline. The egg is quickly passed down between the plates of the ovipositor, and dropped into the pocket thus made, the time occupy- ing little more than a minute for tile operation. A single saw-tly usually deposits only one egg in the same leaf, and after laying the egg she goes around to the upper side of the leaf and amines it carefully, rests awhile, and then tlies to another leaf and repeats the operation. The egg is oval, slightly flattened on one side, and remains in the leaf about two weeks. It increases in si^e apparently by absorbing the juices. The young larva on hatching makes a semi-ciicular cut through the upper surface and crawls on the top of the At first it is nearly white in color, with a yellow- ish brown head. Almost immediately a slimy, olive-colored liquid be- gins to over the whole body; the head appears black under the slime, and the body be- comes dark. The an- terior segments of the swell out and the head is retracted, so that the little larva appears club-shaped. It begins feeding on the upper surface of the leaf eating out small holes the size ofapinhead. This work continues and as the lirvi grows until the leaf becomes entirely skeletonized. Full size is reached in less than a month. The larva casts its skin four times, and usually eats its cast skin.
