117. Eueupithecia cisplatensis (Berg, MS.) 
(Prout), uov. sp. (Plate XLVIII, fig. 5.) 
5 • 21-23 mm. Head, body and legs nearly uniform light grey, 
tinged with brown. Forewing with antemedian and iiostinedian 
lines scarcely indicated except by dark vein-dots, the former at about 
one-third, bent outwards in cell, the latter at about two-thirds, 
angled on R* ; cell-spot large, dark, roundish, the faintest possible 
indications of a darkened median shade ; terinen with some rather 
indistinct dark dots between the veins. Hindwing with no distinct 
markings excepting a large, dark, roundish cell-spot and dark 
terminal dots ; in addition, very weakly banded with alternately 
greyer and browner shades or lines, which are sometimes slightly 
better expressed at inner margin. Underside similar, but with 
antemedian line obsolete on forewing, on the other hand with a 
distinct postmedian line of small dark dots, angled on Rh 
Buenos Aires, latter half of January, in coll. L. B. Prout 
et coll. Br. Mus., the type ($) January JO, 1903, in coll. 
L. B. Prout; Gran Chaco, near Florenzia, October 1902, 
in coll. Br. Mus. 
I know of no other localities. Specimens were sent 
from Buenos Aires to the British Museum by Prof. C. Berg, 
as long ago as 1886, under the manuscript name of 
Eueiipithecia cisplatensis \ but they have never yet been 
described. 
118. Sebastia maleformata (Warren). 
Sebastia maleformata, W^arren, Nov. Zook, ii, 112 (1895). 
Buenos Aires, one J, December 21, 1903 (A. F. Bayne), 
in coll. L. B. Prout. 
Warren’s type was from S.E. Brazil. 
119. Eupithecia batida (Dognin) (?). 
Eupithecia batida, Dognin, Ann. Soc. Ent. Belg., xliii, 140 
(1899). 
Buenos Aires, one January 5, 1907 (A. F. Bayne), 
in coll. L, B. Prout. 
My specimen is somewhat worn, and although it seems 
to agree with Dugnin’s batida (from Colombia), I cannot be 
certain of the identification, upon such slight material. It 
is not impossible it belongs to the subgenus Stenopla, 
Warn, Nov. Zool., vii, 166 ; it reminds of the type-species
