 and that which follows in our classification. 



(i) Tachyris ilaire, Godart, Plate 

 XXXV, Fig. 4, 3 ; Fig. 5, ? (The Florida 

 White). 



Butterfly- — The hind wings of the male 

 on the under side, 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

 which the wings are almost wholly dull 

 blackish on both sides.

 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
