We believe that the present material should be referred to 

 vicina, assuming that the specimen from Guatemala, subse- 

 quently discussed by Saussure, is the same as the type described 

 from "America meridional." That author states that the 

 tegmina are hyaline, while in well preserved material at hand 

 the marginal field is opaque, buffy. In our series, however, are 

 badly discolored specimens in which this is completely lost, the 

 tegmina being plainly discolored but uniformly hyaline tinged 

 with light brown. A Central American female, associated with- 

 out hesitancy as the opposite sex of the males here recorded, 

 agrees fully with a Guatemalan female described by Saussure, 

 this strengthening our above conclusion. 



It is certainly natural, under such circumstances, that Giglio- 

 Tos considered his Costa Rican material distinct. It is, however, 

 surprising that, at the present day, when so much more has been 

 ascertained as to individual size variation, and the differences in 

 color to be expected from that to which the terms recession and 

 intensification have been applied, Giglio-Tos should have de- 

 scribed, as two distinct species, material from the same locality 

 representing so palpably such individual variation and nothing 

 more.

Compared with S. nahua Saussure the present insect diifers 

 structurally most in the weaker supra-coxal expansion of the 

 pronotum and weaker armament of the same, the males with 

 surface of pronotal collar and its margins entirely unarmed. In
