\i^Loiiis B. Prout on the 
Fieiinlum present. Forewing with cell more than one- 
half, C free, SC^ free, SC^ from cell anastomosing with 
gQ3-5 fi- 0 , 1 ) before apex of cell. Hindwing with C 
approximated to SC to one-half of cell, SC^ separate from 
R^, AH separate from R^. The following subgenera are 
differentiable :— 
Suhgenns I. — Saljns, Mabille. Antenna extremely long, 
in ^ simple or simply ciliated. Terminal joint of palpus 
long. Forewing rather broad, apex not produced: einten- 
oiata, Mab., aenea, Butl., infelix, Butl.,* p^iechi, Dogn.,j‘ 
carneitincta, Prout, ruhens, Prout. 
Suhgenns II. — {Lasioi^s, Warren, nom. praeocc.) Micro- 
dontopera (Warren, MS.), Prout, nov. subgen. Antenna 
moderately long, in ^ shortly or moderately bipectinate. 
Terminal joint of palpus long, P^orewing not broad, its 
apex acutely produced: J chilenaria, Felder,| felderi, 
Butl.,II elentilinenta, Butl.,^ eiidora, Prout. 
Suhgenns III. — Antygophanes, Prout, nov. subgen. ^ 
antenna very shortly bipectinate. Terminal joint of palpus 
moderate. Abdomen very long. Forewing narrow : orhi- 
fera, Prout. 
Note.—I have, unfortunately, not seen Salpis antenncita, 
Mab., the type of the genus, but Mabille’s figure and de¬ 
scription leave no doubt that it belongs to the aenea group. 
Staudinger, Hamb. Magalh. Sammelr., ii, 81, 82, evidently 
unacquainted with this group of moths, rashly accuses 
Mabille of error in referrino' it to the Geometridae, and 
erects a new genus, PseiidosaJpis, on the type Salp>is alhi- 
pxinctaria, Mab., Nouv. Arch. Miis. Paris (3), i, 155. This 
species, which also I do not know in nature, seems quite 
rightly placed in the genus, but as I am not quite sure as 
to the subgenus, I have not cited it in the above survey.

X Other slighter and less constant differences exist in the less 
dense scaling (less mixed with hair-scales), less crenulate margin of 
hindwing, somewhat more slender terminal joint of palpus, occasional 
approximation or even anastomosis of SC of forewing with C, closer 
approximation of to in hindwing, etc.
