31. GAEIDES Scudder. 



Type: Clirysophanus Dione Scudd. 



Tills group contains tlie largest species of the tribe, and is closely related to 

 Chrysophanus, from which it may quickly be distinguished by the entirely 

 iinswollen condition of the basal tarsal joint of the middle and hind legs of 

 the male, and by the squarer form of the hind wings of the same sex. The 

 general appearance of the two sexes is usually less diverse than in most of our 

 Villicantes, although in this particular it agrees pretty closely with one of the 

 sections of Epidemia. The fore wings are more pointed than usual, even the 

 females partaking of this character to a certain degree ; the cell is but little 

 more than half as long as the fore wing ; the markings of the under surface 

 are unusually heavy, and the posterior border of the hind wings always has a 

 greater or less number of orange lunules. The fore tibiae of the male are 

 about three-fourths, and of the female about two-thirds the length of the hind 

 tibiae.
