Leucania multilinea Walker 1856

(Fig. 52, Map 29)

Identification: Forewing length 15–17 mm. Overall appearance of the forewing is tan with a dark brown shading along Cu vein to end of discal cell then continuing above vein M2 to outer margin. There are two tiny black dots associated with vein Cu, one is at middle of discal cell below vein Cu (can be reduced to absent) and one at end of discal cell above vein Cu. Postmedial line consists of 2–3 tiny black dots one on vein M2 and one on vein CuA2. Terminal line consists of a series of minute black dots. Hindwing is white with a few black dots between veins along posterior margin.

This species resembles L. adjuta but the forewing horizontal dark stripe is much darker in L. multilinea. The hindwing is white with only tiny black dots along the posterior margin in L. multilinea and in L. adjuta the hindwing is gray with a distinct marginal band of darker gray.
