in Guerrero (H. H. Smith); Guaremaua (Conradt, in mus. Staudinger), Totonicapam 
8500 to 10,500 feet (Champion). 
Allied to 7. condensaria, Guen. Varies slightly in colour, some specimens being 
much paler than others. We figure a pair from Omilteme. | 
Mr. Champion’s specimens were found upon the trunks of pines, on the summit of 
the Cordillera.
