Guenee (^) gives the locality for his specimen as 
“ Brazil (?).” The forms wliich appear to agree with his 
description, and which I take it that Moschler (^) has 
rightly identified from Porto Rico, are widely distributed 
—West Indies, Central America (^), Para (in coll. Br. Mus.), 
Rio Janeiro (coll. Br. Mus.), being localities known to me. 
It seems to pass in some collections, as well as in the 
“ Biologia,” as 'primgnaria, Guen. ;* but the true privig- 
naria, from Martinique, was a “ cafe-au-lait ” coloured 
species with the distal margin of forewing somewhat 
elbowed. Further south (Sao Paolo, Porto Alegre, Monte¬ 
video, Buenos Aires) iyficdA paradoxata, is replaced, so far 
as I can judge from meagre material, by a local race which 
entirely lacks the orange shade behind the postmedian of 
hindwing and has the red spot pro.ximally to the subter¬ 
minal metallic one above R^ wanting or much reduced. 
Should this prove constant, as I expect, it will stand as 
Phrygionis paradoxata incolorata (Warren, MS.), Prout, nov.

Butler’s type was from the Amazons. The species is 
also represented in coll. Br. Mus. from Mexico and Rio 
Janeiro, and in coll. Dognin from Costa Rica, Ecuador and 
south Brazil, so that it evidently has a wide range. It 
varies considerably, and may conceivably be the same as 
vest'Uaria H.-S., Samml. Aussereur. Schmett., i, fig. 368 = 
resistaria H.-S., ibid. p. 41, with which Butler compares it.
