34 LEPIDOPTERA HETEROCERA 
Pingasa-form, C shortly approximated to cell near base, SC? separate, R? characteristic, M! well separate. 
Cf genitalia with uncus bifid, gnathos rounded, terminating in a long blunt arm, harpe with scobinated 
clasper, vinculum lobed, penis pestillate. 
Early stages scarcely known. Larva of muscosaria red, lichen-like, found on fences (Lucas, Vict. 
Nat. Vol. 5, p. 25). 
Related to the preceding genus, and likewise forming a fairly natural group, though not quite so 
strictly consistent in all details. Distinguished by the less short cells, less elongate hindwing (especially 
of the gf), with less shortened costa, the constant anastomosis or connection of SC! of the forewing 
with C and SC?, presence of raised scales on fore- as well as hindwing, and several slight characters in 
venation, palpi, antenna, etc.

1) Pingasa multicolora on type label. It is not unlikely that not only this, but some at least of the following five species, will prove to be forms 
of the very variable emz/raría.
