Fourteen Oriental species of Paragus Latreille are treated and keyed. The following three species of the subgenus Paragus s. str. are described as new: annandalei Ghorpade, sp. nov. (northwest Himalayas), brachycerus (Malaya, Java), and sluckenbergi (Philippines) Thompson, spp. nov.; and also two species of the subgenus Pandasyoplhalmus Sluckenberg: goeldlini (Timor), and villipennis (Malaya, Sumatra, Java) Thompson, spp. nov. Paragus (Paragus) brachycerus Thompson, sp. nov. is recorded as a new predator of the coffee aphid, Toxoptera aurantii (Boyer de Fonscolombe), from Java; and its puparium figured. Some olhecjiew and known prey (and flower) records of Paragus spp^ arealso included. Male- tcrminalia of all new species and of alratus de Meijere, politus Wiedemann, and rufocinclus (Brunelti) are illustrated. Leclotypes are designated for Paragus alratus de Meijere, P. laliusculus Walker and P. politus Wiedemann. Paragus keiseri van der Goot is a new junior synonym of P. politus Wiedemann. Tentative synonymies are proposed for Paragus politus Wiedemann (= ? Piphella indica Brunelti, ? Paragus rufiventris Brunetti), and Paragus rufocinclus (Brunetti) (= ? Paragus abrogans Goeldlin de Tiefenau). Graptomyza laliuscula (Walker) (from Paragus) is proposed as a new combination. Paragus quadrifascialus Meigen is a new record for the Indian subcontinent and that of P. bicolor (Fabricius) from there is confirmed.
