GENUS TACHYRIS WALLACE 

 (THE FLORIDA WHITE). 



There are about seventy species in this genus, all of which 

 are found in the Old World, except the one which occurs in our 

 fauna, and which has a very wide range throughout the tropics 

 of the New World. 



(1) Tachyris Uaire (Godart), Plate XCV, Fig. 1, cT ; Fig. 2, 9 . 

 Our plate gives such an excellent reproduction of the upper 

 side of the wings of this species that no formal description 

 seems necessary. A melanic form of the female sometimes 

 occurs in which the wings are almost wholly dull blackish on 

 both sides. Normally the under side of the wings in the female 

 is pearly white marked with bright orange at base of fore 

 wings. Expanse 2.50-2.75 inches. 



Occurs in southern Florida and throughout tropical America. 



GENUS PIERIS SCHRANK 

 (THE WHITES). 



Medium-sized butterflies, generally white in color, marked 

 on both upper and under sides with darker lines and spots. 

 Antennae clubbed; palpi short, compressed, with the last joint
