Rostrum reaching the posterior coxae. Body ochraceous thickly punctate, the punctures very coarse on the corium. Length: 7 mm. Dist.: Vietnam (Nghean), India, Myanma.</p> <p><em>Notobitus</em> <em>excellens</em> Distant: Head, antennae and pronotum brassy-black; rostrum extending to about base of mesonotum. Scutellum finely granulate, brownish forwads apex. Corium brown, obscurely and faintly pilose, menbrane brassy brown. Posterior femora considerably incrassated, finly granulous, inwardly obscurenly tuberculate, and with a series of acute tubercles on upper surface, beneath with a strong and curved spine a little beyond middle preceded and followed by some smaller spines. Posterior tibia moderately curved, their inner margin denticulated. Length: 27-32 mm; breadth between pronotal angles: 8-9 mm. Dist.: Vietnam (Phutho), India, China.</p> <p><em>Notobitus</em> <em>elongatus</em> Hsiao: Close to <em>N. melaegris</em> Fabr., but body narrower, head longer and pronotum with collum black. Length: 20.7 mm. Dist.: Vietnam (Phutho), China.</p> <p><em>Trematocoris insignis</em> Hsiao: Allied to <em>T. lobipes</em> West., but pronotal lateral lobes straightly produced forward lateral angles acute, and posterior tibiae unicolorously dark. Length: 22.5 mm; width: 7 mm, width beetwen pronotal lateral angles 8.5 mm. Dist.: Vietnam (Laocai), China.</p> <p><em>Physomerus parvulus</em> Dall.: Head and pronotum ocharaceus, corium brownish. Scutellum black, with a central longitudinal and the margins brownish. Clavus, corium fuscus, membrane piceous. Body benneath and legs ochraceous. Posterior femora and tibia unicolor; posterior tibia with the base and apex, and all the tarsi fuscous; antennae black. Length: 19-21 mm; breadth between pronotal angles: 5.5-6 mm. Dist.: Vietnam (Gialai), Myanma, China, Indonesia.</p> ER -
