Hah. North America, from Pennsylvania to Florida, Texas, Arizona, and the Pacific.

 (Zoettling 3 ) ; Guatemala, Motagua, Polochic, and Central valleys (F. D. G. & 0. S.), 

 Duefias and San Geronimo (Champion). — Cuba; San Domingo. 



This species has a wide range over the Southern States of North America, and 

 spreads throughout the whole of Mexico and Guatemala ; it also extends to Cuba and 

 San Domingo. As might be expected, there is considerable diversity in the coloration, 

 especially in the females, some of which have the orange tint of the males, others being 

 of a sulphur-yellow ; the latter, so far as we know, are chiefly found in the peninsula 

 of Florida. On the underside too great diversity prevails in this sex, the secondaries 

 being much more heavily marked in some specimens than in others. The outline of 

 the inner border of the dark margin of the secondaries also varies considerably, being 

 more evenly serrated in some individuals than in others ; and this is most noticeable in 

 specimens from San Domingo, but we have precisely similar examples from Central 

 America, so that the character is not of specific value. 



T. nicippe has a considerable range in altitude in Guatemala, being found from near 

 the sea-level to the height of 5000 feet. 



B. No patch of felted scales on the primaries beneath. 



a. Outer margin of secondaries angular. 



d. Subcostal branch of secondaries emitted long before the end of 

 the cell. (Pyrisitia, Butler.)
