Rh and feet are not visible from a back view. Elevated portions of the body are reddish colored, the expanded portions yellow, and the eyes black.

After some days the second shedding takes place. When the chrysalis has reached its full development it is a little more than a twelfth of an inch in length. Then comes the last transformation, the shell bursts and the perfect winged creature appears. (Fig. 8.)

The female chrysalis differs from the male by having a wider body, and the lateral posterior lobes undivided. It is agile and active. The antennæ and feet extend beyond the margin of the body but in repose are drawn in and cannot be seen from a back view. The segmentary divisions are the same as in the larvæ. When sufficiently developed to reach a twelfth of an inch in length, it assumes an elongated octangular figure. When in motion the feet are not visible beyond the body, the antennæ alone over-reaching it. The back has a ridge running lengthwise, with two other ridges crossing it as has been described in the male. In this stage it is torpid. The last moulting now takes place and it passes to the stage of the perfect insect. (Fig. 9, 10, 11.)

The male insect (Fig. 8) has a slender, elongated body, eyes very distinct, antennæ delicate, thorax well defined, abdomen long, and ending in two filaments twice as long as the body, and furnished with a stiletto shaped appendage. The wings are colorless and transparent and have two thick sinews running lengthwise through them. The body is of a reddish yellow in color and the eyes are black.

The female insect has an ovoid-oblong body with skull and segmentary division outlines evenly fringed. There is a notch at each eye and one at the caudal extremity. The antennæ and feet are concealed by the expansion of the sides of the body. Between the posterior lobes and the anus there is a space triangular in shape, in which by the aid of a microscope, two symmetrical lobes can be seen, and in the center a caudal appendage. The back is of a greenish
