Synchloe Hiibner, D' Almeida nee Hlibner (falsely states that Synchloe was orig- 

 inally monotypic and makes a pseudotype of S. autodice Hiibner), Arq. Zool. 

 Estado de Sao Paulo, vol. 2, p. 299, Jan. 3, 1941; Pap. Avulsos Dep. Zool., 

 Sec. Agr. Brazil, vol. 3, p. 102, June 4, 1943. 



Type: Synchloe autodice JIiibneT=Tatochila autodice (Hiibner). 

 Type by reason of original designation and also by being sole included 

 species. 



Since this genus has just recentl}^ been redefined (Field, Proc. U. S. 

 Nat. Mus.^ vol. 108, pp. 108-110, 1958), there is no need for discussion 

 of its characters here. 



The 13 species included in this genus are divided into five species 

 groups on the basis of the type of aedeagus and differences in the 

 wing patterns. It was not found necessary to include genitalia 

 characters in the key. 



Key to the species and subspecies of Tatochila 



1. Hindwing below with a distinct white spot covering the lower discocellular 



vein and a considerable area of white along both sides of this vein (Groups 



B and C) 2 



Hindwing below lacking this white spot and with lower discocellular vein 

 outlined with black; or if white spot is present, it is restricted to the vein 

 only (Groups A, D, E) 19 



2. Hindwing below with interspace Sc + Rj containing a small oval or irregularly 



shaped spot or streak in the middle (Group B) 3 



Hindwing below with interspace Sc+R, lacking this spot (Group C) . . 5
