all feeble-bodied, feeble-winged, of weak and intermittent flight, and frequent 

 woods and grassy spaces, loving the shade. " Distinguished by their 

 peculiar flight, which is of a feeble, wavering, dancing character, and not 

 long sustained ; neither do the insects rise far above the ground. Wallace, 

 in writing of the species found on the Amazons, says he does not 'remem- 

 ber to have ever seen any species rise four feet from the earth, while the 

 greater part of them do not exceed as many inches.'' Some genera of the 

 allied Morphine are said by Wallace to be 'truly crepuscular, never flying 

 by day except when disturbed. ^ * * They remain hid during the 

 day in the gloomiest shades of the forest.' " — Scudder. 



As before set forth, here are four genera, Arge, Hipparchia, Chionobas 

 and Erebia, in which the preparatory stages of species resemble in habits 

 and form the Hesperidse and certain moths. The last two are Arctic or 

 boreal. The American Erebias, Epipsodea and Magdalena — this last re- 

 presented on the shore of the Arctic Sea by Fasciata, (see But. N. A , 

 vol. iii, pt. vii for this,) the two evidently being forms of one species — 

 fly at the extreme north, or on the summits of the loftiest peaks of the 

 Rocky Mountains. Chionobas Semidea a'so flies within the Arctic circle, 

 as far north as Cumberland Island, and in Labrador, but there are isolated 

 colonies at two other points, namely, the summit of the White Mountains 

 of New Hampshire, and the high peaks of the Rocky Mountains. C. 

 jutta is boreal, being found in Labrador ; but it reaches farther to the 

 south than any other of its genus — to Quebec, Ottawa, and Bangor, 

 Mame, where it flies at low elevations. Arge and Hipparchia are found 

 inhabiting the temperate parts of Europe, and the hrst of these even 

 crosses into Northern Africa. Erebia Magdalena and Chionobas Semidea 

 live under the severest condition?. Mr. David Bruce says of Mag- 

 dalena and its habitat : " It is found in the most uninviting looking 

 spots it is possible for a naturalist to explore — black, barren, detached 

 rocks, that look as if an immense peak had fallen and split into fragments ; 

 hardly a blade of grass or a patch of lichen to relieve the utter desolation. 

 I have never found this species but among such broken rocks, varying 

 from 12,000 to 14,000 feet elevation. The sun gleams out, and awakened 

 into activity by its beams, comes Magdalena, flitting leisurely, then sud- 

 denly taking an upward flight, it soars' around. Another of same species 

 springs up from the rocks, the usual skirmishing chase ensues for a few 

 minutes, the sun is again obscured, and the insects disappear as if by
