468 PROCEEDINGS OF THE NATIONAL MUSEUM vol. los 



Museum, and Dr. Emilo Ureta-R. of the Museo Nacional de Historia 

 Natural, Santiago, Chile. 



All specific and subspecific descriptions were prepared to supplement 

 the illustrations and should be studied with that in mind. 



The descriptions of the following new subspecies were prepared by 

 William D. Field and are credited solely to him: Tatochila theodice 

 staudingeri and T. microdice fueguensis. 



Genus Theochila Field 



Theochila Field, Proc. U. S. Nat. Mus., vol. 108, p. 106, 1958. 



Type: Pieris maenacte 'BoisduYol— Theochila maenacte (Boisduval), 

 by original designation. 



This genus with characters as given in the original description. 

 Only one species is included and it is here rather provisionally con- 

 sidered to consist of two subspecies. Its position until the present 

 time has always been a matter of much speculation and doubt. It has, 

 in a single decade, been placed in four different genera by four different 

 authors.
