[PART iv. 



FAMILY 11. -EURYGONID^E. (2 Genera, 78;Species.) 



GENERAL DISTRIBUTION. 



This small family, separated from the true Erycinidae .by 

 Mr. Bates, is confined to the tropical forest-districts of con- 

 tinental America. The genera are : 



Eurygona (71 sp.); Methonella (1 sp.); the latter found in 

 Equatorial South America. 



FAMILY 12. ERYCINID^. 1 (59 Genera, 560 Species.) 



This extensive family of small, but exquisitely beautiful 

 butterflies, is especially characteristic of the virgin forests of 

 the Neotropical region, only a few species of three genera ex- 

 tending into tne Nearctic region. The more important genera, 

 and those which have an exceptional distribution, can alone be 

 here noticed. Charis extends from Brazil to New York ; Apo- 

 'demia from Brazil to California, Utah, and Oregon ; Amarynthis 

 inhabits the Brazilian and Antillean sub-regions ; Lepricornis 

 and Metapheles are small genera found only in the Mexican 

 sub-region; Lymnas, Necyria, Ancyluris, Diorhina, JEsthemopsis, 

 Anteros, JZmesis, Symmachia, Cricosoma, Calydna, Lemonias, 

 NympJiidium, Theope, and Aricoris are common to the Brazilian 

 and Mexican sub-regions. All the other genera (40 in number) 

 are only known from the Brazilian sub-region, and of these a 

 considerable proportion are confined to the damp equatorial 

 forests of the Amazon Valley.
