when the hickory leaves began to expand. This would give the egg 

 period 201 days. They began to spin June 11, giving a larval period of 

 51 days. With a pupal period of 28 days, we have a period of 79 days 

 from the egg to the imago, or 280 days from the egg to the same. It is 

 evident from my date of obtaining the eggs that they were obtained from 

 one of the latest specimens, and that eggs from one of the earlier moths 

 would add one or two months to the egg period, as there is evidently 

 only one brood in a season of any of our species of Catocalee. 



The food plant, as given before, is hickory. When ready to spin they 

 fastened leaves together in the breeding cage, preferring seemingly the 

 dry leaves under the fresh food. Several spun under a leaf lying on the 

 dirt in the bottom of the box, fastening bits of sand together for the bot- 

 tom of the cocoon and this to the leaf. These points would seem to im- 

 ply that they do not spin on the tree, but in the dry leaves under the tree 

 on the ground. This is further corroborated by several years ago finding 

 a chrysalis in leaves on the ground under a hickory tree, that produced C. 

 Flcbilis. The cocoon, like the other species, is but slight, with the hooks 

 of the cremaster fastened into the posterior end.
