Mr. G. W, Peck, of New York, found that the red blotches on larvae are not uniform, 

 and are more prevalent on the late brood, though some are entirely green and correspond 

 in colour to similar spots found on the leaves of the wild cherry at that season. 



The larva feeds on the leaves of the wild cherry, and undergoes transformation in 

 the earth ; the chrysalis is smooth and of a deep brown colour. 



Moth. — Head and thorax chocolate-brown, the two latter portions with a purplish or 

 rosy tinge ; the sides of the palpi, and a stripe in the middle of the thorax, tawny -yellow ; 

 abdomen brownish, with tawny-yellow spots, and the hind portions of the segments dark 

 brown ; fore wings angulated and excavated on the hind margin ; chocolate-brown colour, 

 with a faint purplish or reddish-grey tinge towards the base ; black and chocolate-brown 

 bands and patches ; hind wings dull yellow^, with the outer half chocolate-brown ; short 

 bluish lines above the tips, and a dull yellow spot upon it ; the ocellus (or eye-shape 

 spot) black, with a large pale-blue pupil. 



This moth is double brooded.

Mature larva. — Head apple-green, granulated, flattened, and triangular, with bright 

 yellow side lines ; body light-green, studded with pointed white granulations ; seven 

 oblique yellowish lines on each side ; caudal horn nearly straight, rose-coloured, yellow at 

 sides and sometimes at tip ; legs at tips reddish-brown ; breathing places reddish- 

 brown. Larva undergoes transformation in the ground. The chrysalis is dark chestnut- 

 brown, tolerably smooth, and with a short triangular rough terminal spine, which is more 

 prominent in the mal»i. 



Feeds on the leaves of the apple tree and plum ; has also been found on the elm, and 

 is said to feed on the swamp rose, Rosa Carolina. 



The larva, when irritated, emits a musical chirping sound. 



Moth. — Head and thorax fawn colour, with a roseate tinge ; body fawn colour, with 

 a dark-brown dorsal line ; fore wings denticulated on the hind margin ; fawn colour 

 clouded with brown, with black and brownish-red spots and patches ; hind legs rose 

 colour in the middle, with a brownish patch at the tip, crossed by two or three short 

 whitish lines ; ocellus (or eye spot) black, with pale-blue centre and short whitish lines 

 between the ocellus and the inner margin.

 Caudal horn straight, granulated and violet-coloured. Breathing places elliptical and

 October to beginning of November at the base of willows.
