284 THE BUTTERFLIES OF NEW ENGLAND. 



pale reddish brown. Prolegs brownish fuscons, clothed Avith fine, not long, downward 

 directed hairs; the tubercles of the tip white. Length, 34 mm; length of thoracic 

 tubercle, 5 mm. ; tip of thoracic tubercles 8 mm. apart ; base of thoracic tubercles 4 mm. 

 apart; breadth of body, greatest, 5.5 mm., least, 3.5 mm. ; breadth of head, 4 mm. 



Chrysalis (83 : 12, 13). Head, wings and the appendages in front, pale, brownish, 

 shining yellow, the appendages often paler, the posterior edges of the wings a little 

 darker; summit of head bluish white; thorax pale, discolored lilac, the pronotum with 

 a pair of silvery white spots ; dorsal tubercle of second abdominal segment, dark brown ; 

 on either side of it a broad, fuscous band, subparallel to the border of the wings, extends 

 from the middle of the first segment, where the two unite, to the middle of the 

 fourth segment, where they are more widely separated than the width of the tuber- 

 cle ; between this band and the wings the abdomen is occupied by a broader, oblique, 

 nacreous band; rest of the abdomen to the seventh segment inclusive, cream-colored; 

 the seventh segment has a dorsal and lateral patch of dark yellowish brown, and there 

 is a broken dorsal line of the same extending forward nearly to the great tubercle ; 

 beneath, the fifth to seventh abdominal segments are obscure fuscous, with a cream- 

 colored ventral stripe; terminal segments and cremaster dark yellowish brown; 

 the eighth segment has a cream-colored patch at the spiracles. Spiracles horn-colored 

 with white lips. Length, 23.5 mm. ; height at thorax, 7 mm. ; height at abdominal 

 tubercle, 10 mm. ; breadth of abdomen, 5 mm. ; near tip of wings, 9 mm. ; at base 

 of wings, 8 mm. ; at head, 3.5 mm. 



Distribution (19 : 3). The range of this butterfly is similar to that of 

 the preceding species (archippus) though less extensive ; its boundaries are 

 the Atlantic coast on the east, the Gulf of Mexico on the south, the Missis- 

 sippi valley on the west, and about the 43d parallel of latitude on the 

 north. Messrs. Allen and Austin found few specimens in Iowa, and 

 Mr. Parker says it is rare at Grinnell ; it has been taken at Ames 

 (Osborn), and Davenport (Putnam), in the same state. It occurs also 

 in eastern Nebraska (Dodge), and eastern Kansas (Snow), and in a 

 varietal form (arizonensis, which may prove distinct) in Arizona and New 

 Mexico. Strecker says it is even found in Mexico. Mr. Riley did not 

 find it abundant in eastern Missouri ; on the north it is found at Beloit 

 (Chamberlin), and is "common" at Racine, Wise. (Hoy), but "not 

 common" in southern Michigan (Harrington Cook), " frequently seen " 

 in northern Illinois and Indiana (Worthington), where Mr. Boutell has 

 found it at Evanston ; ' ' occasionally found in a few localities " at Cleve- 

 land, Ohio (Kirkpatrick)*, "found occasionally" about London (Saun- 

 ders), and at Essex County, Out. (Lowe), the only known localities in 

 Canada. It has been taken in twenty counties in Pennsylvania (Conradi) , 

 at Staten Island (Davis), and in New York at Rochester, "not common" 

 (Bunker), near Albany (Lintner, Gray), and at West Farms, N. Y. 

 (Angus). 



It is tolerably abundant in the southern portion of New England, tol- 

 erably common in the central Connecticut valley, and occurs about as far 

 orth as the annual isotherm of 45°, the northernmost points recorded 



*Kirtlaud, probably, however, speaking of species. He collected in southern, as well as 

 the whole of Ohio, calls it an "abundant" in northern Ohio.
