(Delias geraldina)
Delias geraldina is a butterfly in the family Pieridae. It was described by Henley Grose-Smith in 1894. It is found in the Australasian realm where it is endemic to New Guinea. The wingspan is about 70 mm. Males are white, the forewings with a black distal area not reaching the cell and narrowed to the tornus, its edge slightly curved and sharply defined. The hindwings are without a marginal border but with a fine black line on the margin. The fringes are black. Females are similar to the males, but with a yellow tinge. The black area of the forewings is usually broader. The hindwings have a narrow black marginal border which is wider anteriorly.
