(Edwards), Texas (Belfrage), New Mexico and Arizona. In tlic north 

 it occurs as far as the southern boundary of tiie Canadian fauna and 

 beyond, for it has been taivcn at Montreal rarely (Fyles, Lyman, Caul- 

 field), at Ottawa (Fletcher), in the Adirondacks of New York (Hill), at 

 London, Ont. (Saunders), and even at Nepigon (Fletcher) ; while w-est 

 of Lake Superior and east of the Rocky Mountains its northernmost 

 localities known are Xcw Jefl'erson (Allen) and DesMoines, Iowa (Aus- 

 ten), Minnesota (Seudder), Manitoba (Fletcher), Dakota (Morrison), 

 Montana (Cones), Kegina, Assiniboia (Fletcher), and Old Man's River, 

 Alberta (Geddcs). In the Rocky Jlountain region it has been taken in 

 Colorado by Ridings, on the Ute Pass road to South Park (Snow) and at 

 Apex Gulch and Bailey's Ranch (Mead) ; besides in New Mexico and Ari- 

 zona, already mentioned, and in the Big Horn Mountains (Edwards). 

 West of the mountains it is only known from the observations of j\Ir. 

 Henry Edwards, who has taken it in northern Oregon (Portland, 

 Dalles) and Vancouver Island. 



In New England it is considered a rare insect, but has occasionally been 

 found in considerable numbers and is well distributed, at least over the 

 southern portion. The only northern locality in which it has been found 

 is Norway , Me. , where it occurred in abundance ( Smith) . In the southern 

 half it has been taken at Portland, ile., Milford, N. H. "not common" 

 (Whitney) ; in ^lassachusetts, at Williamstown (Seudder), Springfield 

 "not uncommon'" (Dimmock, Emery) , Mt. Tom (Emery) , Holyoke Range 

 (Parker), Amherst (Merrill), Belchertown and Leverett (Sprague), sev- 

 eral localities in tlie vicinity of Boston "very rare" (Faxon, Sprague, 

 Seudder), Walpole (Guild), and on Cape Cod at Hyaunis (Seudder), 

 Sandwich (Bethune, Fish), Eastham (Fish), and Provincetown (San- 

 born) ; there are specimens in the Yale College iluseum from Guilford, 

 and it has been taken at Farmington, Conn. (Norton). 



Haunts. The butterfly frequents blossoms, especially those of golden- 

 rod (Solidago, — Sanborn, Seudder), Jersey tea (Ceanothus — Lintner), 

 milk weed (Asclepias — Saunders) and thistle (Cnicus — Fish). Abbot 

 says his specimens were found in oak woods, frequenting the blossoms of 

 redbud (Cercis) ; it usually occurs about flowers in the most open places, 

 exposed to the fullest rays of the sun. Mr. Allen es2:)ecially states that in 

 Iowa it is "found on the edges of prairies by the woods — not in the 

 woods themselves," and in the east it generally occurs in the neighborhood 

 of thickets. 



Oviposition. The only egg I have seen was found tucked into the 

 angle made at tiie extreme tip of a wild cherry twig by the equal forking 

 of two little shoots, so that it was diflficult to tell which should be called 

 the terminal shoot. 



Food plant and habits of caterpillar. Abbot states that the larva
