Prosotas noreia, the white-tipped lineblue,[1] is a species of lycaenid butterfly found in South Asia and Java.

Forewings and hindwings: the purple gloss not extended to the dorsum of the hindwing nor to the costal and terminal margins of either wing, all of which are narrowly edged with the pale brown of the ground colour, beyond which along the termen of both wings are slender anteciliary lines.

Hindwing: the following transverse, somewhat crenulate, slender white lines, between each pair of which the ground colour is slightly darker: an oblique pair at base, a pair along the discocellulars and a very irregular sinuous discal pair, the last dislocated at vein 6, the posterior portion curved and shifted outwards; these are followed by a subterminal inner and outer series of arrow-shaped lunules and an anteciliary dark line, this last with a very slender inner whitish edging; finally, a minute block spot near the termen in interspace 1a; another similar spot in interspace 1 and a very much larger round black spot in interspace 2; all these spots touched with white on the inner side.

[3][4] "A geographical form of Prosotas nora, Felder, but with the external margin less convex in the fore wing.

Hind wing with the basal patch violaceous, blue, the marginal spots more obscure, the usual extra-caudal one excepted, very obsolete.
