142 LEPIDOPTERA HETEROCERA 
hair-pencil, but without process, in both sexes with all spurs. Abdomen slightly or moderately crested. 
Frenulum in gf fairly strong, from before slight basal expansion, in OQ vestigial. Forewing broad, with 
costa arched, apex falcate, termen little oblique, tornus pronounced, cell rather less than one-half, 
DC incurved, SC! from cell, free, SC? normal, R! just stalked, R? rather above middle, M! stalked : 
hindwing with termen bent at R!, thence rather straight, waved, tornus pronounced, cell rather short, 
DC? slightly incurved, C anastomosing with cell at a point near base, thence moderately diverging, 
SC? stalked, R? very characteristic; M! stalked. 
Early stages unknown. 
Almost certainly a close relative of Bathycolfodes, in spite of the different shape ; agrees practically 
in every other character.

Characters. — Face smooth, somewhat rounded. Palpus in c rather short, second joint shortly 
scaled, third joint small; third joint in Q elongate. Tongue present. Antenna in both sexes bipectinate 
to two-thirds, in gf with moderate (in Aumidaria longish) branches, in Q with short branches. Pectus 
hairy. Hindtibia in c not dilated, in both sexes with four rather approximated spurs. Abdomen usually 
somewhat crested. Frenulum in cf typically rather strong, but short (in some species more slender, 
arising from before basal expansion, in Q wanting or vestigial. Forewing with apex falcate, or with a 
small rounded excision between R! and R', cell less than one-half, produced apically, DC? deeply 
incurved, very oblique posteriorly, SC! free, or anastomosing briefly with C, SC? normal, R! connate, 
M! connate, approximated or very shortly stalked; hindwing with termen rounded, or with a small tail 
at R3, inner margin long, cell less than one-half, DC oblique posteriorly, C anastomosing at a point, or 
appressed, continuing approximated for a little, then moderately divergent, SC* stalked (sometimes 
almost connate), M! stalked. 
Early stages unknown. 
We have extended this genus to include (at least provisionally) species of somewhat varying 
shape and facies, but tolerablv uniform structure. They share with the two preceding genera a rather 
strong build, firm texture of wings, with thick but smooth scaling, the coloration generally a good deal 
variegated, and different on the two surfaces. The pectinate antenna (in both sexes, so far as known) 
distinguishes the present genus. 
Tyne of the genus : /ypocoela subfulva, Warren (1897). 
1) The generic name ZZv4ocoe/rs has been thrice used in zoologzy, commencing with Eschscholtz (1836, Co/eog£era), but the form 7Zygocoe/a is 
not preoccupied.
