Flavinarosa Gen. n.

Type species: holoxanthia Hampson
The wing venation is much as in Narosa and the antennae are similarly filiform in the male. The forewings are a rufous, or brownish yellow with an obscure, fine, irregular curved medial that is somewhat darker.

The genus is defined by the genitalia of both sexes.

In the male the valves are distally expanded, slightly falcate costally; the uncus is apically bifid with a sclerotised subapical spur ventrally; the aedeagus vesica contains a series of small cornuti. The eighth tergite is slightly produced so this may be the sister genus to Heringarosa discussed below.

In the female the ductus bursae is sclerotised, irregularly spiralled, and there is a distinctive inverted triangular field of scobination in the bursa, the spines directed away on each side of a ridge that bisects the triangle (Fig. 128).

In addition to the type species the genus contains a further species,- obscura Wileman (Taiwan), hereby transferred from Narosa, comb. n.

Narosa fletcheri West, a yellow species from Sri Lanka, has all forewing veins rising independently from the cell and is certainly not a Narosa, probably not a limacodid. The holotype is the only specimen and is somewhat worn and damaged.
