[I could not say positively whether this species is resi¬ 
dent in Paraguay or not, as I have only met with it during 
the months of June, July, and August. The male is much 
more common (or careless) than the female, but the pro¬ 
portion of males to females is very badly balanced. The 
large forests are the only places in which they can be met 
with. I have never found the nest.— W. F.~\
