130 LEPIDOPTERA OF NORTH AMERICA. 



and three approximated on the last rings; the intermediate ones 

 are minute. The outline of the body above the ventral surface is 

 furnished with a row of minute spined papulae. 



Bright green, with a broad dorsal yellow band containing a 

 reddish purple one, which is constricted opposite the second and 

 third pairs of anterior papuloe and dilated into an elliptical patch 

 in the middle of the body. This is almost separated from a smaller 

 elliptical patch which is constricted opposite the third pair of pos- 

 terior papulae and ends in a small round patch. The anterior and 

 posterior papulae are crimson and the intermediate ones green. 

 The superventral row of spined papulae are green. 



In September, on the leaf of apricot. Imago in March.

Body and fore wings uniform dark ferruginous, with two small 

 subapical white spots, and in the % two more near the base of the 

 wing beneath the median nervure. Hind wings pale reddish-brown. 



Larva. Body semicylindrical, truncated obliquely before and 

 behind, with a pair of anterior long, fleshy, subvascular, slenderly 

 spined horns and a pair smaller beneath them, above the head; a 

 posterior similar pair and a smaller anal pair beneath them. The 

 superventral row of papulae are rather large and densely spined. 

 After the last moulting the longer horns become moderate in 

 length. 



The portion of the body between the anterior and posterior 

 horns is a fine bright green color, bordered anteriorly and super- 

 ventrally by white, with a central, dorsal, oval reddish-brown patch 

 bordered with white, which color is again edged by a black line. 

 The horns, papulae, and anterior portion of the body are reddish- 

 brown, with a small yellow spot between the anterior horns, while 

 the posterior pair are placed in a yellow patch. 



The spines with which the horns are supplied produce an ex- 

 ceedingly painful sensation when they come in contact with the 

 back of the hand, or any portion of the body on which the skin is 

 thin. 



On a great variety of plants; fruit trees, the rose, Indian corn 



{Zea mays), and a number of other plants.
