1902.J GROTE — COCOON OF TELE A POLYPHEMUS. 405 



advantageous to the insect and for the reasons given by me above. 

 So that perhaps in the future both Telea and Actias may become in 

 this way sessile. And perhaps, when we grasp all the facts which 

 arise in connection with cocoon-making, we may be disposed to 

 recognize in caterpillars, these lowly organisms, an intelligence in 

 so far akin to our own, as it is evidently based upon an identical 

 perception of external conditions. We are here at the simple 

 sources of Mind in Nature. 



Hermaphrodite of Samia cecropia. 



The occurrence of hermaphroditism or gynandromorphism in the 

 Emperor Moths is sufficiently rare. I may record the fact here 

 that an example of Samia cecropia disclosed on June 3, in which 

 the left side, antenna, both wings, and abdomen, so far as can be 

 externally observed, is female, while the right side is as completely 

 male. On the right side the male abdominal clasper can be seen, 

 wanting on the left, so that we have to do with a true herma- 

 phrodite. Incompletely formed eggs were extracted from the left 

 abdominal opening under pressure.
