paratype,

U.S.N.M.

No. 56T07. According to

W.

E. China,

who

com- pared this species with Walker's type of Ricania trigutta^ it differs

from

the type in tegminal venation

and

genitalia. F. trigutta has a halfline of transverse veinsbetween the subapical line

and

the trans- verse fold; the color i^attern is the

same

in both species.
