PSYCHE.

There were no signs of mating until 

 the box was put into strong sunlight, 

 when in less than five minutes the pair 

 were in coitu, and so remained for 

 about two hours. 



Our moths differed somewhat from 

 those described by Mr. Fernald in his 

 '•Sphingidae of New England." 



The $ had the top of the head, thorax, 

 and first two abdominal segments of a bright 

 green — almost parrot-green — the dorsal line 

 being a trifle browner, and the sides of the 

 abdominal segments a little yellower. The 

 next two segments of the abdomen were 

 almost orange, the second browner on the 

 dorsum, and the first having a brown dorsal 

 line. Both these segments were edged pos- 

 teriorly with dark brown. The rest of the 

 abdomen was dark brown, and ended in 

 heavy anal tufts, those on the sides being 

 black, that in the middle yellow-brown. 

 On the sides of the first two abdominal 

 segments, and on the dorsum of the second 

 were small tufts of blue hairs. The upper 

 part of the palpi, the sides of the thorax, the 

 legs and the underpart of the abdomen were 

 black. The under part of the palpi, the first 

 joint of forelegs, and the sides of the thorax 

 just beneath the base of the wings were 

 bright canary yellow, as was a spot between 

 the second pair of legs. On the yellow 

 abdominal segments there was a broad black 

 ventral band. 



When freshly emerged the transparent 

 parts of the wings were covered with black 

 scales thickly enough to look almost as 

 opaque as the dark border, but these scales 

 quickly rubbed off as the moths moved about. 

 The forewings had a brown costal band, a 

 much wider band on the outer margin, with 

 a rust-colored spot near the apex and a brown 

 patch at the base of the wings, continuing as 

 a band along the hinder edge. Veins dark 

 brown. When freshly emerged there was a 

 patch of green hairs overlapping the base of 



the wings, but these soon rubbed off. The 

 hind wings were edged with rusty brown, the 

 band being widest on the inner border. 

 Veins rusty brown. All these brown bands 

 were opaque, and the transparent parts of the 

 wings were irridescent in the light. Legs 

 black, irridescent in the light. Antennae 

 wide, club shaped, with a little spine at 

 the apex, rusty black, serrate on the two 

 edges. 



The $ differed in having no blue tufts on 

 the abdomen; smaller antennae, which were 

 not at all serrate; smaller anal tufts; and 

 yellow, instead of orange, on the abdominal 

 segments. The brown dorsal line on these 

 segments w*as wider than on those of the $ . 



The moths were very quiet unless 

 put into the sunlight when they at once 

 began to fly about almost incessantly. 

 Sugar and water were put on the net- 

 ting over the box, but I am not sure 

 that they fed at all. 



The 9 began to lay her eggs at about 

 9.30 a.m., July 7th. The eggs were 

 small, oval, bright green. Sixty eggs 

 were laid the first day, and became 

 slightly depressed on the next day. 

 The moth would lay fifteen or twenty 

 eggs, making a great noise and fuss 

 over them, and then would seem ex- 

 hausted, and rest for a long time before 

 laying more. 



Sixty-one eggs were laid on the sec- 

 ond day. Forty-three eggs were laid 

 on the third day. Forty-four were laid 

 on the fourth day and the $ died 

 before noon, having laid 20S eggs. 

 July 14, at 1 p.m., the eggs began to 

 hatch, having turned yellow two days 

 before. 



Young larva 1-8 inch long, pale yellow, 

 tapering from the large, round head to the
