(3) Œneis katahdin Newcomb, [Plate LXXV], Fig. 2, ♂ (The Katahdin Butterfly).
Closely allied to the preceding species, from which it may be distinguished by its paler wings and the irregular dark band on the under side of the hind wings about their middle. Expanse 1.75 inch.
This insect in recent years has been found to inhabit the summit of Mount Katahdin in Maine.
(4) Œneis macouni (Edwards), [Plate LXXVI], ♂. Type (Macoun’s Arctic).
More like O. 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.
Subfamily LIBYTHEINÆ
(The Snout-butterflies).
These insects may readily be distinguished from all others by their long projecting palpi, and by the fact that the males have only four feet adapted to walking while the females have six, a fact which seems to ally them to the Erycinidæ. On the other hand, the chrysalis is pendent as in the Nymphalidæ. There is but one genus of the group represented in our faunal region.
