74. Oxybelus agilis SMITH, 1856 (Figs. 83-86) Oxybelus agilis SMITH, 1856, p. 378 (rf); BINGHAM 1897, p. 316; TURNER, 1917, p. 190 (çf 9); SONAN, 1940b, p. 21 (Formosa). Oxybelus sabulosos SMITH, 1856, p. 388 ( 9 ) J BINGHAM, 1897, p. 316 ( 9 )• Oxybelus agile: PATE, 1938, p. 387 (listed). Specimens examined: 1 9 2 çf , Kosempo, 30, 31. III. 1908; 5 9 2 c/, Takao, 8, VII, 8, 6-20. 1907; 1907; 1908; 2 9, Polisha, III. 1908; 4 çf, Tainan, II, III. 1909. Distribution. Known from India and Formosa. Remarks. The specimens examined well agree in characters with the descriptions of SMITH and BINGHAM, as far as they go, except that the collar of pronotum is wholly yellow, only medially narrowly interrupted (in one male specimen from Kosempo the interruption is somewhat broad). Some supplements. — Mucro subparallel, comparatively broad, appr. as broad as ocellar diameter and generally relatively short, but in some specimens fairly long, 2.5-3 times as long as its maximum breadth, with apical emargination shallow. Lamellae distinctly bifid at apex. Clypeus, 9 : Figs. 83 and 84 (surface curvature in lateral view), çf : Figs 85 and 86 (do.), temple between the oblique carina and the eye transversely rugoso-punctate, mesopleuron irregularly, coarsely reticulate, sternite 2 with punctures mediocre, each posteriorly shallower and on medial area with interspaces as large as puncture width and on lateral areas less than so, posterior incrassate part of the sternite without puncture, polished. In the Formosan specimens ( 9 çf ) a rounded yellow mark on each side of scutellum is usually present, but sometimes absent, in the former case the marks are markedly varied in size. According to the collecting records this species is considered to appear in cold season as well as in summer (SONAN recorded 16. XL 1926; 15. XL 1933 and 27. VII. 1927). It is strange that among a number of species of this genus recently collected by HANEDA (1970, 1971), MUROTA (1972) and myself (1966, 1968) from various districts of Formosa including the same or closely lying localities where SAUTER and SONAN collected not a single individual of this species is involved. As it is obviously the lowland inhabitants does it suffer serious damage from the insecticide employed in Malaria control? The present species is easily separable from the allied species of Formosa by the black pygidial area, more broadly black-maculated tibiae of the legs and in rf by the much shorter lateral spines of the abdomen. 75*. Oxybelus nipponicus formosus TSUNEKI, 1968C, p. 26 (TSUNEKI, 1971a, p. 29; HANEDA, 1972, p. 6; MUROTA, 1973, p. 119). — Specimens examined:l 9 1 cf, Tainan, II, III. 1909; 1 çf Kosempo, 31. III. 1908. Remarks. This subspecies is similar in its life cycle to the preceding species and therefore, it is markedly contrasted to the fact mentioned above that the present subspecies is still very rich in the lowland districts of Formosa according to our recent investigation.
