with moderate triangular black scale-projection beginning at }, and 
scattered blackish scales between this and base. 
ARGENTINA (Parana); one specimen, 
Platyptilia direptalis, Walk. 
(Oxyptilus direptalis, Walk., B. M. Cat. 934.) 
dg 9. 19-21 mm. Head, palpi, and thorax brown sprinkled with 
whitish, face with short cone of scales. Antennz white spotted with 
dark fuscous. Abdomen brownish, streaked with whitish and 
‘sprinkled with dark fuscous. Legs whitish banded with brownish, 
apex of joints dark fuscous. Fore-wings cleft from before }, seg- 
ments moderately broad, apex of first produced, subfalcate, termen of 
second bisinuate, oblique ; light yellow-ochreous, irregularly mixed 
with ferruginous-brown and in dise with white ; some dark fuscous 
scales towards dorsum about}; costal edge more or less dark 
fuscous ; a triangular dark fuscous blotch, posteriorly edged with 
white, resting on costa just before cleft and reaching % across wing ; 
a slender white bar crossing both segments near termen but not 
reaching dorsum, preceded on second segment and lower edge of 
first by a patch of blackish irroration or suffusion ; cilia whitish, on 
termen with basal half brownish edged with blackish-grey and 
barred with whitish, in cleft grey except on a posterior patch 
enclosing a dark grey bar, on dorsum with an elongate-triangular 
projection of black scales about 3, two or three scattered black scales 
before this and a bar beyond it. Hind-wings cleft firstly from 
before middle, secondly from }; dark grey; cilia grey, third seg-

elongate-triangular projection of black scales extending from middle 
to 3, and some black scales beneath apex. 
CEYLON, Pattipola, 6,000 feet, (Alston); S.Inp1A, Palni 
Hills, 6,000 feet, (Campbell); Nilgiri Hills, 6,000 feet 
(Andrewes); Simla, 8,000 feet (Indian Museum); also 
known from Cape Colony and the Congo. This is identi- 
fied by Lord Walsingham with the European cosmodactyla, 
but is in my judgment quite distinct, though nearly allied ; 
it differs markedly in the colouring, and also especially by 
the narrower segments of hind-wings, of which the second 
has the apex obviously more produced, and the different 
form of the principal dorsal scale-projection on each wing ; 
in cosmodactyla the one on the fore-wings is narrower, with
