After spinning and before pupation the larvae are quite green 

 along the side and greenish all over. 



The caterpillars began spinning on May 3ist and the last one 

 was not ready till June 6th. The chrysalis of ccrogama is from 

 one to one and one-fourth inches long, brown. Light reddish- 

 brown over the abdomen. 



Pupa covered by a slight prunescence. The larvae spun both 

 in paper in the bottom of the jar and in the folds of leaves. 

 When first freed of the larval skin the chrysalis is a beautiful 

 light green. 



But few of the larvae died, two of the pupae, however, failed 

 to give imagoes. The food plant is linden or basswood. The 

 first imago appeared on the 6th of June, having spent a month 

 in the chrysalis state. The last pupa gave an imago on the I3th. 



The first innubens egg hatched on May 7th and the larva 

 passed its moults on the I2th, I7th, 22d, and 27th, and began 

 spinning on June ist. 



Before the first moult, the larva is light gray, streaked longi- 

 tudinally with a darker color. Head, light. True and pro- 

 legs gray. No hump, larva very small. After second moult, 

 the caterpillar is very light gray, almost white. Head, legs and 

 pro-legs, white or gray. The tubercles show up as dark points. 

 After the third moult the larva differs little from the full grown 

 larva, is light gray or almost white with a slight hump over the 

 fifth abdominal segment. The lateral body stripe darker than 

 the dorsum. Black dots or small tubercles show distinctly over 

 the dorsal white. Head, gray, streaked with delicate black lines. 

 After the fourth moult the dorsal gray has an under shading 

 of light brown while the lateral stripe is a beautiful red-brown. 

 The hump over the 5th abdominal segment is rather strong. 

 Tubercles small, black. Head, light reddish-brown. True k-g^ 

 light brown. Pro-legs gray with reddish-brown dots. When 

 well grown the larva is almost white, dorsally, with a lateral 

 yellowish or orange stripe. Black dots and interrupted lines 

 are in the dorsal stripe. Over the 5th abdominal segment is a 

 slight hump with dark patches about it. The top of the first 

 thoracic segment is orange. True legs, orange. Pro-legs, yel-
