Distribution (23: 3). This buttei-fly is a member of the Alleghanian 

 fauna and is perhaps most abundant in its northern half; it is given by 

 Abbot among the insects of Georgia as "very rare," and probably occurs 

 only in the neighborhood of the mountains ; with this exception the south- 

 ermost locality from which it is reported is Philadelphia (Grote, Blake). 

 It seems to have been seldom taken west of New York, but Edwards 

 accredits it to the "Middle States" and Reakirt quotes it among the butter- 

 flies of the Rocky Mountains of Colorado as differing in no respects from 

 eastern types. Indeed it is not impossible that the California eryphon 

 described by Boisduval may prove to be this species, which it certainly 

 closely resembles. Edwards credits it to the western states without speci- 

 fication and in my Buffalo list I added Texas, but I cannot now recall 

 on what authority. To the north it has been taken at Albany and Beth- 

 lehem, N. Y. (Lintner), London, Ont. "not common" (Saunders), Sorel 

 (D'Urban), Montreal very rare (Caulfield), Ottawa abundant (Fletcher), 

 and Halifax, N. S. "not tincommon" (Jones). 



In New England it has been found in widely separated localities, — 

 more abundantly at the south than at the north. It iias been taken in 

 Norway (Smith), Orono (Fernald), Hallowell (Miss Wadsworth) and 

 Brunswick, Me. (Packard), Milford common (Whitney) and the White 

 Mountains, N. H. (Sanborn) , where I have taken it on the very summit of 

 Mt. Madison, .5381', Andover (Sanborn, Scudder),the vicinity of Boston 

 (Harris, Merrill, Faxon, Clapp, Maynard, Scudder), Walpole (Guild), 

 Springfield (Emery, Dimmock) , Amherst (Parker) , Middleboro (Hambly) 

 and Capc^ Cod, Mass. (Fish) ; and Farmington, Conn. (Norton). 



Food plants. The caterpillar feeds on pine, probably on several 

 species. Abbott specifies "short-leaved pine," which Dr. Chapman sup- 

 poses to be Pinus mitis Michx, though P. inops Ait. is mentioned on one 

 MS. (a species Dr. Chapman thinks is not found in Georgia) and P. 

 taeda Linn, on another. Mr. Sanborn has taken it on white pine 

 (Pinus strobus Linn.). Mr. Saunders does not specify the species of
