52 THE CANADIAN ENTOMOLOGIST. 



cription is given of the stages of Cassiope, but how pupation took place is 

 not told, nor is there a figure shown. The young larva as figured has 

 forked tails, and therefore, I apprehend, it must have been drawn after the 

 first moult. 



In North America, are eight or nine species, three at least of which 

 are said to be old world, namely, Tyndarus, Discoidalis, and Disa. One 

 species heretofore erroneously credited to North America, on the authority 

 of Doubleday, E. Vesagus, belongs to the Andes, in South America. 



The group is a very interesting one, and together with Chionobas, and 

 some others, embraces those members of the Rhopalocera, or Diurnals, 

 which are nearest the Heterocera, or Moths, allied to them in important 

 characters in each of the four stages. The resemblances of the larvae and 

 pupge are particularly striking. The latter are destitute of cremastral 

 hooks in Erebia, in Chionobas, even of bristles, and pupation takes place, 

 sometimes on the bare ground, sometimes in or on the sod, in one case, 

 as we have seen, in an imperfect cocoon ; sometimes in a real cocoon 

 beneath the surface of the ground ; or the larva goes into the ground and 

 pupates naked, in a cavity made by the movements of its body, after the 

 manner of nearly all the Sphingida?.*

*NOTE. — Since the foregoing paper was printed, I have seen the Can. Ent. for 

 December, 1SS9, and learn therefrom (Vol. XXI., p. 238,) that Dr. H. Skinner has 

 received examples oi Epipsodea, caught in Assiniboia, about 325 miles west of Winnipeg, 

 and with them one of the var. Brinei, mentioned as var. Siue-occllata.
