This insect occurs in moderate numbers in the provinces 

 of Santa Fe, Cordoba, San Louis, and Mendosa, usually 

 frequenting the edges of groves where it feeds upon the more 

 succulent vegetation. An occasional female specimen is to 

 be found in which the wings are fully developed. (Collect-
