Type locality: "Estrecho de Magallanes al havre Pulket"=Har- 

 bor of Pecket, Province of Magallanes, Chile. 



Additional type data and location of type: Described from 

 specimens of both sexes (number of specimens not stated) said to be 

 in the Boisdiival collection. Not in that collection in the British 

 Museum and not located in the Paris Museum. 



Method of identification: By reference to the original descrip- 

 tion, which is adequate to distinguish this species from the only other 

 species of the genus known to occur in the province of Magallanes 

 (i. e., T. theodice gymnodice Staudinger). 



Synonymical notes: The data for the names listed in the above 

 synonymy are as follows : 



Tatochila microdice sterodice Staudingei-, 1899. Type locality, "Rio Grande," 

 Territory of Tierra del Fuego, Argentina. Described from one pair (locality as 

 given above) and one female ("Punta Arenas," Province of Magallanes, Chile). 

 According to Dr. E. M. Hering of the Zoologisches Museum der Humboldt-Uni- 

 versitat, Berlin, these cotypes were returned to the Hamburg Museum and were 

 destroyed during World War II. This name, based upon scantily marked speci- 

 mens, is clearl3' a synonym of microdice. 



Tatochila microdice allodice Brj^k, 1944. Type locality, "Peninsula Llau Llau, 

 N. of Puerto Nuevo" (near Nahuel Huapi, Territory of Rio Negro, Argentina). 

 Described from a single female in the collection of the Naturhistoriska Riksmuseet, 

 Stockholm. The holotype, illustrated by Bryk, matches perfectly specimens of 

 typical microdice studied from the Province of Magallanes, Chile. 



Misidentifications: Mabille (1888) figures this species under the 

 name Pieris theodice Boisduval. 



Distribution: Southern Argentina (Territory of Santa Cruz) and 

 southern Chile (Province of Magallanes) into the island of Tierra del 

 Fuego.
