species, but in some, such as T. monticola m. and T. koikense m. the phenomenon is observed). Black, with following portions reddish ferruginous to ferruginous yellow: anterior margin of clypeus broadly (not in çf), mandible except reddish brown apex, antenna! joint 1* nearly wholly, 2 beneath, discoloured posterior part* of pronotal collar, wing tegula, base of wings, apex of abdominal segment 1, segments 2, 3 and 4 except a large central blackish mark on each tergite (Fig. 32), base and apex of segment 5, sternite 6 wholly, fore leg* except coxa, mid leg* except basal half of coxa and dark brownish upper side of apical three joints of tarsus, and apex of femur, basal ring* and apical patch of tibia of hind leg (* indicates more yellowish) ; fore and mid femora with a brownish streak or patch, arolia black; wings hyaline, slightly clouded, stigma and veins dark brown. Hairs on eye-incision, lower frons laterally, supraclypeal area and clypeus dense, appressed and silvery, those on temple also silvery, on propodeum fairly close, in some light silverily glittering, on dorsal aspect (on median furrow lacking) and medial area of posterior aspect decumbent forward and on remaining parts of posterior aspect decumbent sideward, sides of the segment glabrous. Form of head from above as in çf (cf. TSTJNEKI 1967C, Fig. 41), comparatively thick, width to length 30:18, OOD : POD = 1:2 width of postocellus more than POD, without frontal furrow. Head seen in front subquadrate (Fig. 30), eyes with ommatidia at frontal surface remarkably large, IOD at vertex and at base of clypeus 3:1, frontal area distinctly raised and flattened above and very gently inclined towards medial line, supra-antennal elevation nose-formed, stoutly carinated on top, carina broadened upwards and excavated by an impressed line from above into two branches, lower margin of elevation marked with a transverse carina which, seen from beneath, forms a triangle with inner carinae of antennái sockets, and triangle half divided from above by a small triangular tubercle (Fig. 31). Antenna apieally gradually thicker, ultimate joint at base appr. twice as thick as joint 3 at base, relative length of joints 3, 4, 5 appr. 6, 4.5, 4, joint 3 appr. 3.5 times as long as broad at apex. Protuberance at the lower edge of lateral inclined part of pronotum in front of procoxa very weak, broadly rounded. Area dorsalis with structure as in çf (cf. TSTJNEKI 1967C, Fig. 44), distinctly marginated by the furrow and medially with an elongated oviform impression; lateral margins of dorsal and posterior aspects marked with a weak carina accompanied inside by a weakly crenate shallow groove. Petiole (Fig. 32) also similar to that of çf, ratio of length to maximum and minimum widht 30 ( = width of head): 10: 5, with spiracles located at a fifth from base, relative length to width at apex of tergites 2 and 3, respectively, 17:13 and 16:15. Fore metatarsus comparatively short, about twice as long as broad. Fore wing with radial cell in its outward extention mediocre, more than in T. obsonator, but less than in T. malaisei. Figs. 30-32.
