 and that which follows in our classification.

 XXXV, Fig. 4, $ ; Fig. 5, ? (The Florida 

 White). 



Butterfly. The hind wings of the male 

 on the underside, which is not shown in 

 the plate, are very pale saffron. The under 

 side of the wings in the female is pearly- 

 white, marked with bright orange-yellow 

 at the base of the primaries. A melanic 

 form of the female sometimes occurs in 

 which the wings are almost wholly dull 

 blackish on both sides. 



Early Stages. We know, as yet, but 

 little of these. 



The insect is universally abundant in 

 the tropics of America, and occurs in 

 southern Florida.

JAMES WHITCOMB RILEY. 



Butterfly. Medium-sized butterflies, white in color, marked 

 in many species on both the upper and under sides with dark 

 brown. The antennae are distinctly clubbed, moderate in length. 

 The palpi are short, delicate, compressed, with the terminal joint 

 quite short and pointed. The subcostal vein of the primaries has 

 four branches, the first subcostal arising before the end of the cell, 

 the second at its upper outer angle, and the third and fourth from 

 a common stem emitted at the same point. The outer margin of
