This species, as identified by the writer, is very close to 

 mexicana Saussure, the principal difference appearing to be 

 the color of the femora, which in these Peruvian specimens 

 here referred to brunnea are yellowish or reddish brown, 

 while all specimens of mexicana seen have had the femora 

 ])iceous.
