Ischnopillia bidentata, sp. nov.(?), length, 7 mm, breadth, 4 mm.Light brown; head, two large patches upon pronotum and tarsi black, and tibiae dark brown. Clypeus transversely trapezoid, nearly straight in front and broadly rounded at sides, strongly reflexed, coarsely rugoso-punctured; forehead triangularly depressed, strongly and densely punctured but rugose anteriorly. Pronotum smooth and shining, exceedingly minutely and sparsely punctured, sides rounded at middle and slighty concave behind, hind angles rectangular. Scutellum unpunctured. Elytra each bearing seven rather deep dorsal striae with large punctures at bottom, the second not reaching to terminal and the fifth very shortj intervals narrow, smooth and rather elevated. Pygidium rather convex, rather densely punctured. Mesosternal process short, compressed, slightly protruded foreward, with a round apical. Longer claws of front and middle legs very deeply cleft, hind tibiae subcolumnar, somewhat longer than tarsi. Male paramera broaden apically with two lateral teeth as shown in figs. 1, 2.Holotype (?), yunnan. Gaoligong Mt., 23. Ⅷ. 1958, paratype 1 (?), same locality and data; coll. Li Chuan-long; deposited in the Institute of Zoology, Academia Sinica.It is very closely related to Ischnopopillia flavomarginata Lin, but the front margin of mesosternal process declined foreword instead of perpendicular, and the male genitalia quite different (figs. 1-3, 9-11) .
