More like 0. jutta in the form of the wings, but differs in 

 coloration. It belongs to a group of species included in this 

 genus, most of which are found in the region of the Rocky 

 Mountains, which are larger and yellower on the upper side of 

 the wings than the two preceding species. Expanse 2.00- 

 2.25 inches. 



Not uncommon about Lake Nipigon, north of Lake Superior.

 only four feet adapted to walking while the females have six, a 

 fact which seems to ally them to the ErycinidcB, On the other 

 hand, the chrysalis is pendent as in the Nymphalidce. There 

 is but one genus of the group represented in our faunal region
