ABSTRACT, Aedes (Finlaya) pallirostris Edwards is resurrected from synonymy with Aedes (Fin.) formo- sensls Yamada and the female, male, pupa, and 4th-instar larva are described and compared with closely related species. The synonymy of Finlaya khasiana Barraud is transferred from Ae. formosensis to Ae. pallirostris.

The latter was synonymized dark brown, bare; maxillary palpus dark scaled with pale scales at apex of palpomeres 3, 4 (some- with Aedes formosensis Yamada by Barraud (1934), whereas the former was synonymized with this spe- times absent on 3), about 0.20 (0.19-0.23) length of proboscis; proboscis dark-scaled, about 1.1 cies by Knight (1968).

Instead, we found a from lateral to dorsal dark submedian area, ocular mosquito very similar to Ae. formosensls, but with scales male genitalia and other adult characters agreeing pale, narrow, lateral dark patches of broad scales with the type specimens of Ae. pallirostris housed near ocular line, postgena with pale-scaled patches, in The Natural History Museum, London (R.
