Characters. — Face smooth. Palpus in cf moderate to longish. in Q more or less long, second 
joint rough-scaled above and (rather shortly) beneath, third joint smooth, distinct, in c moderate to 
longish, in Q long. Tongue present. Antenna more than one-half, in cf bipectinate to beyond one-half, 
the pectinations long, weak, usually erected very little from the plane of the shaft, clothed with long, 
dense cilia, a long apical portion nearly simple, shortly ciliated; in Q nearly simple, shortly ciliated. 
Pectus hairy. Femora glabrous (excepting the hindfemur in the males with specialized hindleg). Hind- 
tibia in gf dilated with hair-pencil and usually a short terminal process, or simple, in both sexes with 
all spurs. Abdomen not crested. Frenulum in C' moderate, rather short, from before basal expansion, 
in Q wanting. Forewing broad, with costa arched distally, and usually somewhat shouldered at base, 
straight between, apex acute, termen moderately oblique. slightly curved or nearly straight, tornus 
pronounced, cell about two-fifths, DC3 incurved, SC! free. SC? normal, R! short-stalked, M! connate or 
short-stalkeed; hindwing subquadrate, apex moderate, termen smooth, rather straight to .R*, there 
elbowed to bluntly toothed, thence straight to tornus, tornus pronounced, inner margin long, cell short 
to very short, DC strongly and continuously oblique (DC? at times somewhat sinuous), C appressed 
(perhaps sometimes with brief anastomosis) to one-half of the short anterior margin of cell, then rapidly 
diverging, SC? stalked, M! stalked (Pl. 3, Fig. 11). c genitalia with uncus pointed or rounded, 
socii always present, usually strong, gnathos usually weak or atrophied, harpe usually narrowed 
above and often with hook or hooks on inner margin (modification of juxta), vinculum rounded or 
extended, penis pestillate, coremata present (at least usually). (Several species examined.) 
LaRva. — Slender, head bifid, a pointed protuberance on eighth abdominal segment. According 
to the figures, would appear to be similar to that of odis (Moore, Le. Ceyl. Vol. 3. p. 426; Semper, 
Reisen Philibb. (2), Vol. 6, p. 641; Guenée, Maillard's La Réunion, annexe G, p. 32). 
PuPa. — Scarcely described; in dissifa pinkish, greenish in front, thorax and abdomen black- 
speckled ( Moore, loc. cit.). 
As restricted by Turner, whom we have followed, an exceedingly natural genus. The character 
which Turner gives (first noted by Guenée himself) — the extreme obliquity of DC of the hindwing — 
is very constant throughout the forms which are quite clearly congeneric. Its adoption has necessitated 
the removal to Prasinocyma of a few African forms which seem rather nearly related, but as they have 
more normal pectinations, and moreover grade off insensibly into forms with perfectly rounded termen 
of hindwing,. their removal is at least a convenience taxonomically. The species left are superficially 
extremely closely allied; the distinctions of leg-structure, though very useful in separating the species, 
are quite certainly not generic. Unfortunately the determination of two of Guenée's species (guadraria 
and veraria) is entirely lost, and he did not even know their localities. As he possessed the C of both, 
and gives in his generic diagnosis « les tibias postérieurs non renflés », we doubt Turners determina- 
tions. A species which may well be Guenée's quadraria occurs from N. India to Burma. 
Type of the genus : Tzalassodes filaria, Guenée (1887). 
Geographical distribution of species. — Indo-Australian, strazgling into ZEthiopian Region.
