摘 要：
The present paper deals with the Chinese species of the hemipterous subfami-ly Tessaratominae. It records nine genera and twenty-three species among whichthree species are described as new. All typq specimens are kept in the Institute ofEntomology, Academia Sinica. Eusthenes femoralis, n.sp.(fig.12) Above castaneous or purplish castaneous, more or less tinged with olivaceous;body beneath brown or yellow-brown, the knees and apex of claws black; connexi-vum dark green or greenish-black, spotted with ochraceous at segmental bases; apexof scutellum yellow; membrane dark brassy-ochraceous; antennae black, the basestained with red-brown, the extreme apex brown. Head wrinkled, the lateral lobes rather strongly reflexed on each side; anten-nae fairly closely pubescent. Pronotum broad, anterior margin thickened; sides obli-que, much narrowed towards the anterior; posterior angles subprominent, roundedScutellum transversely wrinkled; connexivum rather broad. Apical teeth of pos-terior femora directing towards the apex and making each with the femur an anglenot greater than 45 degrees (fig.13); apex of genital segment rather convex whenviewed caudally; paramere as shown in fig. 15.Length: ? 28--31 mm. ? 29--30 mm.Breadth (abdomen): ? 15.5-19 mm. ? 16--18 mm. Hab.: Kweichow 1930, VIII; Fukien; Yunnan 1956, VI, 19. Allied to E. robustus, distinguished by the body beneath pale coloured, the ochra-ceous spot of connexivum very large, occupying 1/3--1/2 the area of each segment andby the backward direction of the femoral teeth; where as in robustus, the femoralteeth are directed more or less inwardly and present an angle which is sensiblygreater than 45 degrees (fig.14). Mattiphus yunnanensis, n. sp. (fig. 27) Above cupreous purple, vertex, pronotum, scutellum and sides of corium usual-ly green or brassy-green; connexivum purplish-brown or piceous, narrowly ochraceousat segmental bases; apex of scutellum pale brown; antennae black, the basal seg-ment and sometimes the second partly red-brown, apex of third and basal portionof fourth milky-yellow, the extreme apex brown. Underside yellowish or reddish-brown, with golden green reflections. Lateral lobes broad, the side margins deeply sinuate behind and the latero-posterior angles not protruded. Pronotum rather rugous, sides rounded and reflex-ed, disc coarsely and closely punctured. Connexivum wrinkled and punctate. Meso-sternal furrow long, extending to near the apex of the segment where it is morelightly impressed. Length: ? 24-25 mm. ? 28-30mm. Breadth (abdomen): ? 14-15 mm. ?17-18 mm. Hab.: Yunnan. Resembling M. splendidus in general appearance, but of larger size, with thelatero-posterior angles of the lateral lobes not protruded and the paramere dif-ferently shaped (figs. 27,32). Asiarcha angulosa, n. sp. (fig. 37) Body oblong, narrowed at the base of pronotum and before the apex of abdo-men. Above metallic green, corium partly purplish, sides of pronotum marginedanteriorly with yellow; antennae pale brown, the third segment darker, its apex aswe1l as the base of the fourth milky-yellow, the rest of the fourth segment black.Underside yellow-brown with greenish sheen. Head closely wrinkled, lateral lobes long and broad, second and fourth segmentsof antennae equal in length. Pronotum with the anterior margin broadly concave,the antero-lateral angles strongly produced, extending to a little beyond the apexof head; sides straight, slightly divergent in front; surface wrinkled, closely punc-tate. Male genital segment tri-sinuate at apex, paramere as shown in fig.34. Length: ? 23-24 mm. ? 28-29 mm. Breadth (abdomen): ? 12.5-13 mm. ? 15 mm. Hab.: Yunnan. To be separated from A. nigridorsis by the antero-lateral angles of pronotummore strongly produced, the male genital segment, paramere and the female caudalsegments differently shaped (figs. 33, 34).
