Gcomctridac of the Argentine Bc^ublie. 335 
with the postmedian line of the hindwing placed further 
distad and without a dark border beneath. The specimen 
has since been determined for Dr. Bastelberger (I do not 
know by whom) as Stenaleidia go'isea, but it scarcely seems 
to me possible that this can be correct. 
Typical S. grisea is from S.E. Brazil, and it is very 
likely that the species will be discovered in the Argentine 
Republic.

Boarmia celosoides, Dognin, Ann. Soc. Ent. Belg., xxxix,

Tucuman, in coll. Bastelberger. 
Dognin’s type was from Ecuador.

Occurs also in Paraguay (coll. Br. Mus.). 
Excepting their generally somewhat larger size, I can 
find absolutely no difference between the group to which 
this species belongs and typical Stenaleidia. Unless the 
whole of that genus were suppressed as structurally in¬ 
separable from the old-world Aids, it would seem impossible 
to xeiei junctilinea to the last-named. Provisionally I can 
point to nothing more definite by way of distinction than 
the constant coincidence of SC^'^ in Stenalcidia, which I 
have not yet found in Aids. 
239. Stenalcidia despecta (Prout), nov. sp. 
(Plate XLVIII, fig. 7.) 
d $. 24-30 mm. Face fuscous ; palpus fuscous, paler beneath ; 
d antennal pectinations rather long. Thorax concolorous with fore¬ 
wing, tarsi pale-marked at the ends of the joints. Wings somewhat 
narrower than in most of the genus, the crenulations of termen of 
hindwing pronounced. Forewing pale greyish ochreous, usually 
dusted with fuscous, very variably in intensity, the least dusted 
part being placed distally to the postmedian ; lines very ill defined, 
usually obsolete except at inner margin ; antemedian line (when 
discernible) from costa at beyond two-fifths, outcurved in cell, 
thence oblique basewards to inner margin at from one-third to two- 
fifths (variable) ; postmedian from costa at beyond two-thirds.
