44 LEPIDOPTERA HETEROCERA 
termen not strongly convex, waved, inner margin not elongate, cell less than one-half, DC? deeply 
incurved anteriorly, becoming very oblique posteriorly, C approximated to cell to at least one-half, not 
very rapidly diverging, SC? connate or more usually short-stalked with R'!, rarely just separate, R? from 
near Rl, M! widely separate. 
Early stages unknown. 
Perhaps another derivative of Ter$za, but rather isolated; hindwing proportions differing from 
those of all the preceding genera of the group. 
Type of the genus : Sf/agnode/a lucida, Warren (1893). 
Geographical distribution of species. — N. India to Tibet.

20. GENUS CRYPSIPHONA, MEYRICK 
Crypsiphona. Meyrick, Proc. Linn. Soc. N. S. Wales (2), Vol. 2, p. 9o1 (1888); Turner, ibidem, 
Vol. 35, p. 630 (1910). 
Characters. — Face not protuberant, smoothly scaled. Palpus moderate, second joint hairy 
beneath, third joint moderate (melanosema) or short. Tongue developed. Antenna rather long, in c 
bipectinate to at least three-fourths with moderate branches, apex minutely ciliated, in Q minutely 
ciliated. Thorax sometimes with slight anterior crest. Pectus and femora densely hairy. Hindtibia 
in c sometimes dilated (ide Meyrick), sometimes simple (ocultaria), in both sexes with terminal spurs 
only. Abdomen not appreciably crested, with lateral tufts. Frenulum fully developed. Forewing with 
costa very slightly arched, apex rather pronounced, termen oblique, subcrenulate, cell nearly one-half, 
DC slightly incurved (sometimes nearly straight), SC! from cell, anastomosing with C and with SC? 
(occasionally SC? even touches C at a point), SC?5 from near to or even very short-stalked with R!, 
M! separate; hindwing with costa rounded, termen crenulate, tornus more or less rounded, inner 
margin long, cell somewhat less than one-half, DC very oblique, nearly straight to sinuous, C shortly 
approximated to cell, then strongly diverging, SC? separate (or connate, fide Turner), M! separate. 
G* genitalia : uncus bifid (two broad arms), emarginate at the tip, gnathos practically atrophied, harpe 
of irregular shape, with projecting sacculus, penis rounded, with a strong thorny cornulus on the vesica ; 
on the eighth sternite there is a fold emitting a fringe of spatulate scales, divided into three parts by two 
pairs of longer scales. 
Early stages apparently undescribed; larva of ocultaria on Eucalyftus. 
Type of the genus : Cryjsiphona melanosema, Meyrick (1910) 1). 
Geographical distribution of species. — Australian.

I) lurner's selection is the oldest known to us, but is rather unfortunate, as he redescribes the genus from ocu/faria ; moreover, other strong 
recommendations which have been put forward for the selection of types point to ocu/faria as the better choice; it is the commonest and best-known 
species, and the generic name lias a similar significance to the specific one.
