Bhopalodes arqentina, Berg, An. Soc. Cient. Argent., xv,

Corrientes, 2 December 1876 (Berg). 
I know this species only from Berg’s description, from 
which it is clear that it is a true Rhopalodes. It is not 
improbable that a closer acquaintance will show it to 
supplant some better-known name, e. g. variegata. Warn 
(Nov. ZooL, vii, l7l), ab. deriifata. Warn (Nov. Zool., xiv, 
246), from Brazil and Paraguay. 
63. Rhopalodes (?) muscosaria (Berg). 
Rhopalodes muscosaria, Berg, An. Soc. jCient. Argent., 
xix, 273 (1885). 
Province of Buenos Aires, one $ (Berg). 
Also unknown to me. On account of the small size 
(22 mm.), and the fact that Berg knew the $ only, I have 
ventured to query the generic position. The insect is 
described as having the forewing greenish (or grey-green), 
with waved, denticulate black lines, white- or greyish- 
margined, the hindwing white. 
64. Rhopalodes otophora (Front), nov. sp. 
(Plate XLVIII, fig. 37.) 
^ 9- 28-30 mm. Forewing wliitisli fleshy, irrorated with 
brown, the basal, median, and marginal areas marked with fuscous 
greyish; lines blackish, slightly interrupted (more so in the 9 )> 
namely : a very irregular line bounding basal area, throwing strong 
projections into and below cell; an antemedian from about one-third 
costa to one-half inner margin, oblique outwards to middle of cell, 
thence approximately perpendicular to inner margin, but more or 
less dentate; a postmedian from beyond two-thirds costa to about 
three-fourths inner margin, outangled between SC" and R' and 
between R'* and Mh incurved between R^ and submedian fold ; a 
grey-brown line between basal and antemedian, following the same 
course as the latter ; a faint line dividing the pale area distally to 
postmedian ; central area pale in the middle, especially in costal 
part ; discal mark elongate, standing in an elongate, somewhat ear¬ 
shaped pale patch, which is more conspicuous in the $ than in the 
type (cj); a pale subterminal line, an indistinct dark subapical 
dash, dark tornal spot, and weak, much interrupted terminal line.
