C. O. HOUGHTON, Ent. News, xni, 160, note on habits 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. 



EPHYDRIM:. 



BECKER, Berl. Ent. Zeitscb., XLI, 91-276, 1896, has given an excellent monograph
