Genus PTEROCOTES Ewing 
PTEROCOTES ABERRANS MEXICANUS, new subspecies 
FIGURE 24, a—c 
Types.—Male and female, adults, from Tinamus major percautus, 
collected by the author on Cerro Tuxtla, Veracruz, Mexico, March 23, 
1940; in U. S. National Museum. 
The Mexican form of this species is more closely related to P. a. 
aberrans of Costa Rica than to P. taoi of Peru, differing from the 
latter in much larger size, less tapering tip to abdomen, shape of ab- 
dominal segment VII, and the genitalia.
