Those marked thus a are in my collection in the imago state. 

 Of those marked aa I have both imago and cocoon. Of 

 those marked thus t I have the larva, cocoon, and imago. Of 

 those marked thus ft I have the imago, larva, and chrysalis. 

 Of those marked thus % ^ have the cocoon only. Those not

 larvae and mothes but more particularly the cocoons of all or any 

 of these species to assist me in the investigation of the physical 

 properties and structure of the silk fibres of the Heterocera, a work 

 in which I have for some time been engaged.
