Common in S. Brazil, whence came all the types. 
Occurs also in Paraguay. 
I have examined Walker’s types, as well as a specimen 
in M. Dognin’s collection, which has been compared with 
Guenee’s. The sexes differ somewhat, both sexes further 
vary in size, and Walker’s signataria is a light aberration; 
but the species is easily recognised, and the variation is 
not such as to justify the list of synonyms or the confusion 
that has hung over it. It has been erroneously believed 
to be the Tephrosia hyherniaria of Guenee (Spec. Gen. des 
Lep., ix. 264), but I am not aware that the error has 
found its way into print. 
It is quite possible that the following genus of Warren’s 
will have to sink to Odysia. So far as I have checked 
them, the characters of the two genera agree quite closely, 
excepting the curious specialisation of the $ antenna in 
Odysia.
