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 conies 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 ac- 

 tive. The antennae 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 larvie. When suf- 

 ficiently developed to reach a twelfth of an inch in length, it as- 

 sumes an elongated octangular figure. "When in motion the feet 

 are not visible beyond the body, the antennae 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. Si has a slender, elongated body, eyes very 

 distinct, antennae 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 trans- 

 parent 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 seg- 

 mentary division outlines evenly fringed. There is a notch at each 

 eye and one at the caudal extremity. The antennae 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
