GEOGRAPHICAL ZOOLOGY. 



[part IV. 



Family 11.— EUBYGONID.E. (2 Genera, 78 Species.) 



General Distribution. 



This small family, separated from the true Erycinidse 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.— EKYCINID,E. (59 Genera, 560 Species.) 



General Distribution. 



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 the Nearctic region. The more important genera, 

 and those which have an exceptional distribution, can alone be 

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

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

 inhabits the Brazilian and Antillean sub-regions ; Zepricornis 

 and Metapheles are small genera found only in the Mexican 

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

 Anteros, Emcsis, Symmachia, Cricosoma, Calydna, Lemonias, 

 Nymphidium, 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.
