representing individuals of the optimum development, maya the 

 greatest depauperation which is known to occur in the species. 

 Giglio-Tos has given additional characters to separate these,^^ 

 but the series before us shows all to l)e attributable to individual 

 variation, rather than constituting diagnostic features. 



Under this variable species, the names Theoclytes azteca 

 Saussure and mexicana Saussure have already been placed, and 

 it is probable that Pseudovates brericornis Stal, described from 

 Coloml)ia, will also prove to be a synonym. 



The measurements of selected individuals of the series l^efore 

 us are as follows:

The frontal process is more flattened in the females than in 

 the opposite sex, with its apices usually slightly less sharply 

 rounded, while in the males the length of the cephalic coxae 

 averages greater in proportion to that of the pronotal shaft,
