Diagnosis. This species share a similar wing pattern and polymorphisms with S. semialba (Walker, 1863) . Both species have a black streak striking the margin just anterior to the tornus of the forewing (followed Holloway 1985). The forewing is greyish-yellow, and an inverted triangular black patch is present at base, which is smaller than in S. semialba . The postmedial line is composed of a series of black dots; the medial line is wavy above CuA1, the zone between two lines is yellowish-brown. The female of S. grisea has specialized wing pattern with ground color of the forewing greyish-green; a large yellowish-brown spot present at the base and another smaller one on the apex; the medial line blackish-green; a semicircular greyish-yellow spot presents on the anal margin centrally. The male genitalia of both species are similar, but differ by the shape of the costal lobe of the valva, which in S. grisea is concave at basal two thirds and expanded apically, but that of S. semialba is concaved more basally and not expanded apically.
