green than either the head or body, which, are concolorous. 

 Mouth parts blackish. The seven obHque, white bands are bordered 

 above, pink. Caudal horn granulated, almost straight, yellowish 

 white, laterally and purple at tips. Thoracic legs white, changing 

 to pink below, and feet much more of same color. Abdominal 

 legs green. Spiracles cream colored. Under a magnifier the 

 caudal horn displays short, stout spines. Body slender, cylindri- 

 cal, smooth, and when magnified is covered by very fine, white 

 dots. There are two white lines on oval plate, forming a delta 

 with apex pointing posteriorly. Length of body at rest, 33 mm. 

 (about I 1=6 inch), when in motion 40 mm. (about i ,^ inch), width 

 5 mm. (about ,1 inch). Caudal horn 4 mm. long. Before the 

 larva is half- grown very little pink is discernible above the white, 

 sphingial bands. On the first oblique stripe, a little pink appears 

 near the centre of the band, and with each succeeding joint the 

 pink encroaches a little more until it nearly edges the whole 

 length of the last band passing into the caudal horn. About this 

 time, a faint yellow thoracic line is still noticeable on each side of 

 body. This larva was collected near Long Island City, July 13th, 

 feeding on Salix purpurea. 



Mature larva. — Head oval, of a darker green than body, and 

 Avith a light green, vertical stripe on each side looking forward. 

 Back of and adjoining it another of a dark green color. Body 

 slender, smooth and of a beautiful emerald-green frOm dorsum to 

 venter. The seven oblique, white stripes bordered above more of 

 a violet tint instead of the former pink. Caudal horn shining 

 black laterally, and green on dorsal and lower side. Spiracles 

 orange, surrounded by a yellowish ring. Below stigmatal line 

 the lateral surface of body is dotted white, edged by a black ring, 

 which is best seen under a lens. Thoracic feet rose-pink, whitish 

 above. Abdominal feet green. Length of body at rest 55 mm. 

 (2 ,^6 inch), in motion 65 mm. (2 /^ inch). Width of transverse 

 diameter 9 mm. (,| inch), and of the dorso-ventral 10 mm. This 

 last measurement is from dorsum to and including feet. Length 

 of caudal horn 5 mm. (,| inch), and recurved. The oblique or 

 sphingial bands of the mature larva do not now reach into adjoining 

 segment, except the last, passing into caudal horn. 



Mature larva one day before pupation. — In shape and color 

 about the same as previously noted. The lateral stripes pure 

 white and the pink border above now changes into violet of more
