190 LEPIDOPTERA HETEROCERA 
termen usually straight, tornus well expressed, cell nearly one-half, DC? incurved, SC! from cell, some- 
times free, usually anastomosing with C, SC? normal, sometimes anastomosing with SC!, R! usually 
short-stalked or connate (in didifa well separate), R? usually from well above middle of DC, M! separate; 
hindwing with apex rounded, termen rounded, or very faintly elbowed at R? (in fefrasPila angled), cell 
less than one-half, DC? incurved, C approximated (sometimes very closely) to cell to less than one-half, 
then rapidly diverging, SC? stalked, R? very characteristic, M! separate (not remote), or more rarely 
connate or extremely short-stalked. Cf genitalia : uncus parallel. with socii, gnathos strong, pointed, 
harpe with sacculus pointed; penis pestillate, vesica covered with minute cornuli; eighth sternite 
terminating in two blunt points; coremata present; perhaps related to the Zodis-group. 
Early stages apparently undescribed. A few of the larvae are known, and are attached to Acacia, 
Duboisia, etc. 
A very natural genus, with the probable exception of the single African species which we have 
been compelled, for lack of salient differential characters, to lodge here provisionally. In addition to the 
several distinctions noted in our Key, CAlorocoma normally differs from Omfhax, Heterorachis and Heteresthes 
in the dilated c hindtibia; its palpus, though short, is usually stout, and is seldom (perhaps only in 
tachypora) positively minute, whereas in the other genera it is slender and often minute; the antennal 
structure is much more stable; in the hindwing M! is never widely separated at its origin from R9,

1) This synonymy is according to Turner. In coll. Brit. Mus., ex£erza, Walker, stands as verfumnaria; unfortunately Guenée's description 
is somewhat equivocal. 
2! This is in accordance with coll. Brit. Mus., and is fully supported by Guenée's description, which cannot possibly apply to caremar:a, 
Turner (No. 20, infra). The present insect may possibly be another form of dic/oraria, to which Turner has referred corgerrt:.
