San Luis, December 23, 1905 (type), in coll. L. B. Front; 
Meudoza, February 13, 1905, one ^ in coll. L. B, Front; 
La Faz, Mendoza, November 24 and December 22, 1905 
two ^s in coll. A. F. Bayne (all these four collected by 
W. M. Bayne); ? Gran Chaco, near Florenzia, October 
1902 (S. R. Wagner), in coll. Br. Mus. 
Nearly related to N. j^sychidia, Warr., with which it 
agrees in structure. It is of a less brown colour (psychidin 
might relatively be described as tinged with reddish) and 
further differs in the deep inangnlation of the antemedian 
line, the stronger expression of the median and postmedian, 
etc. The Mendoza specimen is less strongly dark-irrorated 
than the San Luis (type), hence its dark lines stand out yet 
more clearly, removing it further in aspect from Warren’s 
species. The Gran Chaco specimen is not precisely like 
the western examples, but I think I am right in referring 
it to this species as a dark variety; yet the tongue and 
palpus seem slightly more yellow-tinged, the course of the 
antemedian line does not look precisely the same, and 
future study may possibly establish another closely-related 
species. 
135. Fsodopsis TORTILINEA (Frout), uov. sp. 
(Flate XLVIII, fig. 13.) 
^ 5-20 mm. Head, body and wings greyish fuscous, more or 
less irrorated with whitish. Forewing with the markings dark 
fuscous, only the broad median line conspicuous ; antemedian line 
from al)Out one-fifth costa, throwing a very strong projection distad 
in cell, and obtusely angled on submedian fold; median line (shade) 
from one-half costa to one-half inner margin, strongly outbent at 
and making a sinus inwards between I\P and SM^ ; postmedian line 
ill defined except in lower half, commencing beyond two-thirds of 
costa, dentate, thickened and strongly sinuate inwards between kP 
and SM-, narrowly i ale-margined distally ; marginal line slightly 
darker than ground-colour ; fringe rather pale, weakly chequered 
with darker. Hindwing unicolorous, somewhat paler than forewing. 
Underside without markings.

I am indebted to Mr. Warren for the generic location 
of this obscure little species, as I have not yet had the 
opportunity of examining his genus Fsodopsis (Nov. Zook,
