(Plates III, IV) 



A brief description of an interesting form of Callosamia 

 angulifera was published in ENTOMOLOGICAL NEWS for May, 

 1908 (page 231). It is now possible to give an illustration of 

 this moth and of its cocoons, which differ remarkably from 

 those of typical angulifera. I first found these cocoons in May, 

 1907, in Berkeley County, South Carolina. At that time eleven 

 cocoons were found, all hanging on swamp-magnolia or bay- 

 trees (Magnolia glaiica) ; all of these cocoons were empty, and 

 were so evidently different from any of our well-known species 

 that I made every effort to procure eggs, larvae, or live cocoons. 

 Early in 1908 I finally secured thirty live cocoons and many 

 more empty ones, all gathered within four miles of the original 

 locality and from the same food-plant, Magnolia glaiica. 



The cocoon of Carolina bears a superficial resemblance to 

 that of polyphemus, though it is not so regularly rounded or 

 nearly so firm in texture outwardly; for unlike polyphcmns it 

 is double, the firm inner cocoon being no larger than a large 

 proincthca, and like that species, open at the top with converg- 

 ing threads. The cocoon is suspended by a strong, slender
