T do not see any good grounds for specifically separating any of these specimens from the others. The length 
of the inferior appendage of the male varies from six-tenths to nine-tenths of that of the superiors 
(or more exactly the superiors vary absolutely in length) in the males from Rio Janeiro. The wings 
of the females vary from almost colourless to deep yellow in the basal two-fifths, the remainder more or 
less smoky (Rio Janeiro).

Mus. Pittsb.), Theresopolis in Santa Catharina 3 ; Paraguay, Sapucay (foster, U. S. 
N. M.: 2 2). 
The dates of occurrence are given in the above table. 
The sexual difference, that the males have one, the females two, post-triangular 
rows on the hind wings, was pointed out by Prof. Karsch?, and is constant for this 
species, B. ineguiunguis, and some species of Macrothemis. Some tendency in the 
same direction is seen in B. vivax (cf. page 281), to a slighter degree in B. pertinar 
(page 284), not at all in rapar (page 285), while in precor a few of both sexes show 
some reduction in this area (page 282). 
For part of the synonymy given above I am indebted to Dr. Ris, who wrote to me 
(2. iii. 705): “ Macrothemis catharina, Karsch, too, is a Brechmorhoga, and there is 
very little doubt of its identity with B. nubecula, Rbr.”
