Geometridae of the Argentine Reimblic. 251 
(= Ypsipetes mutdbilis, Mab., Miss. Sci. Cap Horn, vi, Lep. 
31, tab. iii, 2), from Orange Bay, Patagonia, stated to be 
very variable, may possibly be allied to zona ; but the 
lighter, brighter colour, differently formed basal line, and 
less outangled postmedian, render a union altogether too 
precarious, especially as I only know it from Mabille’s 
figure and description. 
86. Euphyia limbata (Prout), nov. sp. 
(Plate XLVIII, fig. 14.) 
(J. 31 mm. Face somewhat protuberant, with some whitish scales 
(somewhat abraded); palpus red-brown, whitish below; antenna pale 
ochreous, narrowly reddish in centre of shaft above, provided with 
cilia at least as long as diameter of shaft. Forewing with distal margin 
somewhat more oblique than in most of the genus; brownish white, 
irrorated with brown, and rather broadly shaded with brown proxim- 
ally to subterminal, and distally to subterminal except from apex to 
R* and between R^ and ; markings darker brown, namely : a band 
close to base, from costa to middle of cell; a subbasal curved band 
from nearly one-sixth costa to inner margin; a similar, somewhat 
waved, antemedian from about one-third costa ; a postmedian from 
about two-thirds costa, forming two small teeth directed distad on 
either side of R^, two larger teeth or lobes distad on either side of 
M', and becoming a mere line below middle of wing, with further 
distad bends on either side of SM*; traces of less distinct transverse 
lines between subbasal and antemedian bands, and (almost losing 
themselves below middle of wing) proximally and distally to post¬ 
median band; an inconspicuous, extremely minute cell-dot in the 
pale median space ; subterminal line pale, indistinct. Hindwing 
brownish white, with a postmedian dark line from R' to inner margin, 
outbent between R^ and and again below ; marginal area 
broadly infuscated, except apically and in middle (as in forewing), 
and containing indistinct and interrupted traces of a pale subterminal. 
Underside of both wings pale, the forewing with the postmedian 
band distinct, but narrowed, and losing itself shortly below M^, a 
broad distal dark margin almost as above, but somewhat more distinct; 
hindwdng marked as above. 
Cacheuta, November 15, 1904 (VV. M. Bayne), type m 
coll. L. B. Prout. 
Apparently a true Euphyia, DC and of the hind¬ 
wing formed as in the type species. The hindtarsal spinules 
seem stronger and more numerous, but this appearance 
may be only due to the abrasion of some of the scales; in
