GEOGRAPHICAL ZOOLOGY. 



[part IV. 



Family 11.— EUEYGONID^. (2 Genera, 78 Species.) 



General Distribution. 



This small family, separated from the true Erycinidaj by 

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

 tinental America. The genera are : — 



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

 Equatorial South America. 



Family 12.— ERYCINID^. (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. Charis extends from Brazil to New York ; Apo- 

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

 inliabits the Brazilian and Antillean sub-regions ; Lepricornis 

 and Mctapheles are small genera found only in the Mexican 

 sub-region ; Lymnas, Nccyria, Ancyluris, Diorliina, EsthemopsiSy 

 Anteros, Emcsis, SymmacJiia, Cricosoma, Calydna, Lemonias, 

 Nyrrvphidium, 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.
