around the body in the incision between the second and third abdominal 

 segments. After the girdle is in place, the caterpillar seliles into a 

 somewhat crouched position, and then finally arches its body as it awaits 

 the time of ecdysis, several days afterwards. The placing of the girdle 

 occupies about two minutes ; if placed too. far caudad it is liable to 

 interfere seriously with ecdysis. Unfortunately, no observations were made 

 during pupation, so that the method of placing the girdle by the chrysalis 

 was not seen. Described frofll 13 specimens. 



Duratio7i of Pupa-rtnstai s. — The duration of pupal life for fifteen 

 individuals reared averaged 16 days, from June 28th to July 14th, and 

 ranged from 14 to 21 days. The males issued before tlie females.
