Diagnosis. S. semialba shares a similar wings-pattern and polymorphisms with S. grisea . This species has a pattern with greyish-brown forewing and obscure black spot at its base, the postmedial line is a series of round black spots. The differences in the male genitalia from S. grisea are discussed above.

Remarks. This species was recorded by Chen (1982b) as S. ferrifera (Walker, 1863) . We reidentified the specimens and concluded that they belong to S. semialba (Walker, 1863), so S. ferrifera is not found in China and the distribution records should be omitted.
