200. Pero jonesaria (Schaus). 
Azelina jonesaria, Schaus, J. N. Y. Eat. Soc., v, 162 
(1897). 
Buenos Aires, February 25, 1902, end of November to 
December (A. F. Bayne), several in coll. L. B. Prout et 
coll. A. F. Bayne; Mendoza, captured and bred ex ovo, 
one generation in December 1903, and another in April, 
1904 (\V. M. Bayne); La Soledad, Entre Rios, in coll. 
Rothschild. 
Schaus’ type was from S.E. Brazil, and I have seen 
topotypes in coll. E. D. Jones. 
One might almost suspect, in this variable little species, 
a much smaller southern representative of Pero variaria 
(Walk.) = jctniaieensis (Schaus), but its range of variation 
seems even wider than in that species. Besides the 
habenaria-\ike forms (costa of forewing yellowish between 
the lines) which occur in both sexes and apparently in all 
localities with the type, I may mention that I have a 
very red-brown $ from Buenos Aires, and a very weakly- 
marked $ (the large black discal mark of forewing obsolete) 
bred from Mendoza. 
201. Pero fusca (Warren). 
Azelina fusca, Warren, Nov. Zool., viii, 483 (1901). 
Parana, Entre Rios (type $), in coll. Rothschild. 
I know of no other examples, but am inclined to suspect 
that the discovery of the $ will lead to the removal of the 
species to the subgenus Azelina, which is the richer in 
species in the Argentine Republic. P. fusca would seem to 
have much affinity with the new species, P. amnicincta and 
norma, described below. The type is in poor condition, 
which might possibly account for its lacking some of the 
characteristic markings of my new species; but it shows 
larger discal marks on forewing, and a somewhat differ¬ 
ently formed postmedian, and presents a sufficiently differ¬ 
ent aspect to disallow of their union. 
Subgenus II. — Azelina, Guenee. ^ antenna bipectinate. 
202. Pero gonopteraria (Guenee). 
Azelina gonopteraria, Guenee, Spec. Gen. des Lep., ix, 160, 
tab. vi, 5 (1858).
