NORTH AMERICAN BUTTERFLIES. 79 



a connected series of more or less distinct crescents. The middle of fore 

 ^ving is crossed by a band of black, more or less broken in the middle ; 

 inside of the outer band, on hind wings, is a series of black spots, each 

 surrounded by a more or less distinct ring of dusky that sometimes 

 unite to form a band on the inside. There is an irregular black ring in 

 central cell of both ^yings, and an intricate pattern of rings at base of both 

 Avings. Beneath, paler, the black margin absent, but the sub-marginal 

 crescents show as light spots in dark edges ; there are two broken, black 

 bars crossing the fore wing, usually indicated by four spots on the up- 

 per and lower margins. Hind wings, pale ocherous with a more or less 

 distinct marginal band of brownish, that becomes enlarged in the mid- 

 dle of the wing, and encloses a purplish crescent ; a more or less distinct 

 central band of brownish, between which and the outer margin, is a row 

 of small brown dots ; the rings at base of both wings show palely. 



Morpheus is a summer form in which the markings above are 

 heavier, and the brown below intensified and extended. 



There are many variations from the tyi)e in this species, occurring 

 throughout its wide range. Examples from Canada, while they are 

 nearly melanotic above, so great is the suffusion of the black, show a 

 pale central band on fore wings and are much paler below, sometimes 

 very much so, packardii Saund. being evidently an extreme case of this 

 suffusion, with a very pale under surface. Expands, 1.30 to 1.70. Hab- 

 itat, United States, west to the Rocky Mountains, north to British 

 America, west to the Pacific Ocean, east to the Atlantic, including An- 

 ticosti. Winter form in New England occurs from May to June, sum- 

 mer, from July to September : in Florida, they are nearly continuous 

 throughout the yeai-. 



102. PHYCIODES BATESII Beak. 



Bates' Checker. 

 Similar to P. tharos but differs in having the black markings above 

 very much extended, so that the orange is reduced on fore wings, to two 

 bands of spots, crossing outer portion of wing; three or four short bars 

 in central cell, a streak on lower margin, and a spot near middle of outer 

 margin. The hind wings are also crossed by two orange bars, the outer 

 containing the row of spots, and the sub-marginal crescents are more or 

 less distinctly visible. There are two spots in the central cell, the in- 

 ner small and semi-circled by the outer. Beneath, the central bar cross- 

 es the Aving, Avith only a short bar between it and the apex, the lower 

 bar being absent as in P. phaon ; and there are three black crescents on
