With exception of specimens from western Ecuadér, which differ from all others in 
the decidedly more buffy and (especially in females) slightly paler color of the abdo- 
men, I am not able to distinguish satisfactorily specimens from any of the geographic 
areas indicated above, and therefore, for the present at least, consider them all as 
representing a single subspecies. 
b Apparently of purely accidental occurrence on north side of Rio Grande.
