C. O. Houghton, Ent. News, xiii, 160, note on hal)its of adult; oc. at 

 Ithaca, N. Y. N. J.— Smith Cat.; Montreal— Chagnon. 



Note. — In midsummer of 1901 I found this species by hundreds on 



foliage in one of the shady glens adjoining the campus of Cornell Uni- 

 versity, Ithaca, N. Y. There is nothing to show that the larva has any- 

 thing to do with the skunk cabbage.
