208 LEPIDOPTERA HETEROCERA 
costa well arched, termen strongly crenate, excised between R! and R?, a strong tooth at R$, cell less 
than one-half, DC incurved or inangled, SC! from cell, free, SC? normal, M! approximated at its origin 
to R?; hindwing narrow, shaped nearly as in Maxafes, the tail slightly less extreme, cell short, 
DC curved, rather oblique posteriorly, C shortly approximated to cell near base, then rapidly diverging, 
SC? connate or very shortly stalked with R!, M! usually just separate, sometimes connate, very occasi- 
onally minutely stalked (Pl. 4, Fig. 1 3). c genitalia with uncus bifid, widely divided at the base, 
gnathos very narrow, atrophied, harpe serrate along the inner margin, penis rounded, with two small 
horny cornuli ; the eighth sternite terminates in two points; on the eighth tergite there is a plate with 
two long arms, quite distinct from any other form studied, suggesting more affinity with the Actemochroma- 
or Hijparchus-groups than with any of the more specialized forms. 
Early stages unknown. 
A curious genus, apparently quite distinct genetically from the other species with frenulum 
wanting; possibly derived from a form akin to Dooabia. The loss of the frenulum is here accompanied 
by less manifest expansion of the base of costa than elsewhere. 
Type of the genus : Paramaxates polygrapharia (Walker) — Hiyfochroma polygrapharia, Walker 
— Paramaxaltes vagata, Warren (1894). 
Geographical distribution of species. — Indo-Malayan.

Cathydata, nov. gen. Prout. 
Characters. — Face with projecting tuft of scales. Palpus in both sexes with second joint very 
long, shortly scaled, third joint smooth, in c quite moderate, in Q very long. Tongue developed. 
Antenna in Cf bipectinate with moderate branches, in Q simple. Pectus hairy. Hindtibia in C dilated, 
with hair-pencil and process, in both sexes with all spurs. Abdomen not crested. Wings thinly scaled, 
subhyaline. Forewing with costa slightly arched (more so at base), apex moderate, rounded, termen 
slightly waved, oblique, bending and becoming very oblique, tornus somewhat rounded off, cell less 
than one-half, DC? deeply inangled, DC? deeply incurved (thus with a sharp angle at origin of R?), 
SC! from cell, free, SC? normal, R! about connate, M! connate or short-stalked; hindwing with apex 
rounded off, termen produced to a strong tooth at R! and a still stronger at R?, thence crenulate to 
tornus, cell less than one-half, quite short anteriorly, DC? curving, becoming extremely oblique, 
DC? arising far distally to origin of DC?, C approximated to cell for some distance near base, SC? very 
long-stalked, M! very short-stalked. 
Early stages unknown. 
Probably derived from the PArudocentra-Neagathia-group.
