Holotype: U.S. National Museum No. 69743. 
Type-locality: Chile, Santiago Prov., Cajon de Maypo, Cordillera, 
El Centro. 
Distribution: Known only from Chile. 
Described from the male holotype (12-20 Jan. 1948, Tito Ramirez), 
and one 9 paratype with same data, and one @ paratype, El Principal 
(11.1888, V. Izquerdo). 
In general appearance mendora is similar to the North American 
Cochylis felix (Walsingham) but is smaller, lighter, and lacks the 
dark subterminal spot of that species. The harpe of felix is more 
evenly rounded and broader ventrally than that of mendora and the 
aedeagus is stouter. The ostium of mendora is twice as broad as that 
of felix and the spining of the bursa copulatrix is much less exten- 
sive than in the latter.
