210 LEPIDOPTERA HETEROCERA 
Characters. — Head with appressed scales; ocelli posterior; tongue developed. Antennae over 1, 
in Gf simple, basal joint elongate, without pecten, in c* sometimes densely tufted. Labial palpi long, 
recurved, second joint in cf sometimes clothed with long loose rough hairs or with fine expansible hairs 
internally. in Q with appressed scales, rough beneath towards apex, terminal joint in jf sometimes very 
short, thickened with scales, rough anteriorly, or obsolete, in Q (and sometimes gf) nearly or quite as 
long as second, slender or loosely scaled, acute. Maxillary palpi very short, filiform, appressed to 
tongue. Posterior tibiae more or less rough-scaled, with large dense median tuft above; anterior tibiae 
with brush ofscales beneath. Forewings with 1i furcate, 2 remote, 3 from angle, 7 and 8 stalked, 
7 to apex or termen. 9 sometimes out of 7, 11 from middle. Hindwings 1 or over 1, trapezoidal, obtuse, 
cilia 1/2-1; in gf 3 absent, 2 and 4 nearly approximated or stalked, in Q 2 remote, 3 and 4 connate 
or stalked; 5 absent, 6 and 7 stalked; in c with expansible hairpencil in submedian groove. 
Remarks. — Developed from a form approaching Frisilia, The tufted posterior legs of this and 
the allied genera are obviously intended for display (the tuft is often partly metallic), and in an example 
of T. phorcis the two posterior legs are projected beneath the wings and erected on each side of the 
head, which 1 suppose to be the natural attitude of display, similar to that assumed by TAyrsostoma and 
the Heliodinidae, but I am not aware of any record of the habit, and cannot explain its object. The 
species of this genus are rather large insects, more or less conspicuously decorated, sometimes with 
metallic markings; they evidently often occur plentifully, and their quaint appearance invites the 
attention of observers. 
Geographical distribution of species, — Characteristic of Ceylon, with some stragglers in 
Southern India, one in Assam and one in Africa. This and the twelve preceding genera constitute a 
striking natural group which seems to have originated in Ceylon and spread thence to Southern India, 
only two species reaching Assam. ; 
Larva unknown; it is not unlikely that the larval habits of the group may prove to be unusual 
and distinctive.
