Figs. 6-9. Bembecinus paiwanus sp. n. 9:6= propodeum, 7 = postero-lateral incision of propodeum seen from left side, 8 = fore metatarsus, 9 = ditto, from beneath (apical 3 spines missing). outside of postocelli ; head seen in front with inner orbits strongly convergent below. Measurements (relative): head width 60, OOD = POD = 10, IOD at vertex (at anterior margins of postocelli) 38, at base of clypeus (minimum) 16.5, hence ocular index 2.3, clypeal length 12, hence clypeal index 1.38, length to width of labrum 7 : 18, width of antennái socket 5, clypeo-antennal distance 4, oculo-antennal distance 2.5, relative length to width at apex of antennái joints 3-7: 2.7, 2.0, 1.6, 1.4 and 1.2. Propodeum with lateral margins at posterior third fairly acutely edged, incision at its posterior corner seen from above: Pig. 6, seen from left side: Pig. 7, fore metatarsus in vertical view: Pig. 8 (apical 3 spines broken off, right fore leg missing), in ventral view: Fig. 9. Punctures on area dorsalis of propodeum rounded, large, shallow, with distinct interspace, but less than diameter of a puncture, medio-basal impunctate area slightly shorter in middle than length of postscutellum and narrower laterally, including one or two isolated punctures within; apical tergite with a narrow impunctate line in middle. çf unknown. Holotype: 9> Taihanroku, 1908, leg. H. SAUTER. Remarks. The specific trivial name is originated from Paiwan, one of the aboriginals of Formosa, living in and around the type locality of the species. 15*. Nysson basalis taiwanus TSUNEKI, 1968C, p. 2 (TSUNEKI, 1971e*, p. 1 ; HANEDA, 1971, p. 32). —-Specimen examined: 1 cf., Taihanroku, 1908. 16*. Alysson takasago sp. n. çf (Figs. 10-12) çf. The new species resembles most closely Alysson japonicus TSUNEKI which is a close relative of A. ratzeburgi, having the area dorsalis of propodeum triangularly pointed at apex. The present species differs from A. japonicus in the following characters: 1. Antennái joint 3 relatively longer (Fig. 10 from above, Fig. 11 in front; cf. Figs. 13 and 14 in japonicus; from joint 3 apieally both antennae had been devoured by a Dermestid beetle larva). 2. C 1 y p e u s different in form and maculation (Fig. 12, cf. Fig. 15 in japonicus). 3. Punctures on head, thorax and abdomen larger, sparser and stronger (on mesopleuron and abdomen the pat-
