Punctures on frontal area fine, with interspaces about as large as width of a puncture and microreticulated, mesoscutum and scutellum similarly sculptured, but on anterior portion of former punctures slightly closer, mesopleuron on epimeral area practically impunctate, on lower portion punctures slightly large, sparse and hair-bearing, surface well shining. Area dorsalis fairly closely covered with very minute hair-bearing points, surface smooth, but not shining because of appressed hairs, median furrow transversely closely striate, on rest of dorsal aspect and posterior inclination punctures slightly larger, distinct and close, side of segment, together with metapleuron, smooth and polished, former posteriorly with minute punctures sparsely scattered. 45*. Trypoxylon taihorinsho sp. n. Ç (Figs. 33-35) The present species is characteristic in the structure of clypeus, area dorsalis, petiole and in the colour of abdomen and legs and can easily be separated from the known members of the genus. 9 - Length 8.5 mm. Black; ferruginous are mandible, base and apex of antennái joint 1, apex of joint 2, humeral tubercle, basal plate of wing, abdomen except a large blackish mark on posterior half of tergite 1 and a patch on tergite 2 (Fig. 35), apices of all coxae and of fore and mid trochanters, hind trochanter wholly, knees, tibiae except inside and tarsi of fore and mid legs, hind tibia on both ends and on inside and apex of following metatarsus. Mandible and abdomen from apex of tergite 1 posteriorly somewhat reddish, latter with some scattered uncertain obscure blackish or brownish patches; in general ferruginous parts more or less semitransparent, especially markedly so tegula, petiole at base and legs. Remaining parts of antennái joints 1 and 2, flagallam ba^ally and rest of legs castaneous brown (originally black?). Hairs on lower frons and clypsas appressed, silvery, on temple, posterior portion of propodeum slightly long, also silvery, on vertex and mesosciitiim short and greyish white. Hsad from above: Fig. 33, seen in front: Fig. 34, 10D at vertex and at base of clypsjH 5 : 4, 03D : POD — 1 : 3, postocellar width relatively 5, withoat frontal furrow, frontal area gently raised, flattened and gently concave on disc, supraantennal elevation nose-shaped, but thick and broad resembling a tubercle, median carina vestigial, without particular interantennal structure; antenna thick and robust, joint 1 in dorsal view less than twice as long as wide at apex, joints 3, 4, 5 almost equal in length to each other, joint 3 in dorsal view appr. twice as long as wide at apex, following joints gradually thicker and from joint 6 shorter apieally, joint 11 appr. twice as thick as joint 3 at base. Clypeus stoutly bidentate at apex in middle (Fig. 34) ; collar of pronotum medially narrowed, but without excavation and laterally incrassate and rounded at corner, posterior half discoloured, appearing ferruginous, protuberance at side of nape region in front of procoxa in a broad triangle, with apex rounded. Area dorsalis gently raised, not marginated by the furrow, but border of elevation appears in some light to be a weak furrow, especially markedly so on posterior margin, area medially with a broad shallow impression, broader posteriorly, median furrow of posterior inclination deep, spindle-shaped, with an impressed line at bottom, lateral margins of dorsal and posterior aspects of segment distinctly separated from sides by a fine carina, but latter broadly interrupted in middle of posterior inclination. Abdomen (Fig. 35) generally similar in form to that of T. fenchihuense Q

, but thicker and robuster, petiole parallel-sided for about basal half (constant ?), relative length to maximum and minimum width of petiole 30 (= width of head): 11 : 4.7, length to width at apex of tergites 2 and 3, respectively, 16 : 17 and 14 : 20;
