PSYCHE. 



267 



long. Head green and very pointed, 

 ending in a yellow dot at apex. 



Body green, with, on each side, a 

 yellow horizontal on first three seg- 

 ments, seven yelloAV obliques, each 

 crossing two segments, and meeting its 

 mate on the dorsal line. Red spots on 

 dorsum and sides, irregularly placed, 

 and varying in size, number, and posi- 

 tion in the different larvae. Bod\' 

 thickly granulated with yellow dots. 



Caudal horn short, red above and be- 

 low, yellow on each side, from the last 

 obliques. 



Feet and props green, anal shield 

 pointed. 



14 July. Fourth moult. 31 mm. 

 long. Head green, pointed, and with 

 faint \'ellowish lines on each side. 



Bodv green, with horizontal lines as 

 before. Yellow obliques more distinct, 

 the last ones being yellower and wider 

 than the others, and reaching part way 

 up the caudal horn. 



Anal shield pointed, and edged with 

 vellow. Caudal horn short, red above, 

 green beneath, yellow at the sides. 



Feet reddish, props green, spiracles 

 yellow. In some specimens, the spira- 

 cles were set in small red patches. 



The red spots varied very much in 

 the different specimens, those on the 

 fifth segments being most found. 



In three specimens the red spots were 

 surrounded by yellow. 



In all the spots were of a clear, bright 

 red, and not at all of the "bi'ownish 

 red" referred to by some writers. 



The bodies vv^ere thicklv granulated 

 with vellow. 



20 July. Stopped eating. 



27 July. Pupated. 



Pupa of a chestnut brown color, 

 darker than that of Dolba hylacus \ 

 smooth, neither slender nor stout, and 

 about 31 mm. long. 



Dolba hylaeus, Drury. 



A 9 1 caught in Nonquitt, Mass., bv 

 a little girl, laid eggs between 6 and 15 

 August, the child did not notice the 

 exact date. 



The eggs w^ere small, oval, pale 

 green, becoming yellowish two days be- 

 fore hatching. Thev hatched on 17 

 August. 



Young larva, 6 mm. long, pale green, 

 with a caudal horn as long as the bodv. 

 The horn was green at first, but grew 

 black in two hours. 



The larvae ate inkberrj' (^Prinos gla- 

 bra) but would not touch sweet fern. 



They grew pinkish after eating, es- 

 pecially near the head and just before 

 the caudal horn. Like most young 

 sphingid larvae they spun silken threads 

 as they moved about. 



24 August. First moult. They 

 became greener, and showed a faint 

 white line on each side of the dorsum, 

 extending from the head to the caudal 

 horn. Feet and props concolorous. 

 The horn was black, the segments 

 around the base being whitish green. 

 They ate their skins, except horn and 

 mask, after each moult. 



31 August. Second moult. Pale 

 green, with a dark dorsal line, edged 

 on each side with white, extending from 

 head to horn.
