Tsuneki, K.: H. Sauter's Sphecidae from Formosa in the Hungarian Natural History Museum (Hymenoptera)

apieally, with apex narrowly rounded. Pronotum: Fig. 78, black parts of figure raised into a carina, mesopleuron with prepectus somewhat roundly edged at anterior margin, no tubercle nor ridge before mesocoxa. Area dorsalis on propodeum not margined by furrow, but with fine, distinct medial furrow, running down to reach sharp medial elongate excavation at posterior inclination which is not provided with lateral carinae except at its extreme apical end. Petiole of abdomen and following tergites: Fig. 79; fore metatarsus not modified (Fig. 80, left), hind tibia strongly dilated (Fig. 81, lateral view), following metatarsus also incrassate. In fore wing transverse radial vein vertical to costa, abscissa 1 of radial vein appr. half the length of 2, accessory cell weakly outlined, with apex narrowly open, abscissae 1 and 2 of cubital vein equal in length. Body very minutely closely punctulate, half mat, apical portion of each abdominal tergite shining. 9 unknown. Holotype: rf, Chipchip, II. 1909, leg. H. SAUTER. 70. Rhopalum (Oaleeorhopalum) bohartorum TSUNEKI, 1966 (TSUNEKI, 1968c*, p. 25; LECLERCQ, 1973, p. 301, Taihorin, 3 9 1 cf) — Specimens examined:2 9 > Taihorin, XL 1909. Distribution. The Ryukyus and Formosa. Remarks. The collar of the pronotum in the examined specimens is comparatively closely covered with whitish hairs and almost without a median furrow. 71*. Rhopalum (Rhopalum) Succineicollare taiwanum TSUNEKI, 1971a, p. 27 (LECLERCQ, 1973*, p. 302). — Specimen examined:!/, Taihorin, XL 1909. Remarks.lt was pointed out by LECLERCQ (1973) that the 6th antennái joint of the specimen was excavated beneath. In connection with this point, the Japanese typical specimens of the same sex were re-examined and confirmed that the segment was certainly, though very weakly, excavated beneath, despite that at the time of the first publication of this sex it was described to be entire. In the Formosan race the excavation of the segment is somewhat more distinct than in the Japanese representative. The Formosan race is more brightly maculated than in the typical one, especially on the collar of the pronotum. It should further be added that the median furrow of the collar is very weak and indistinct in the Formosan specimens, while it is strong and deep in the Japanese ones as was illustrated in my previous paper (Etizenia 59, 1972). 72*. Entomognathus (Koxinga) siraiya PATE, 1944 (TSUNEKI, 1968c*, p. 17; HANEDA, 1971, p. 33; LECLERCQ, 1973, p. 300, 7 9 12 /, Taihorinsho). — Specimens examined:7 9, Taihorinsho, VIII, IX, X. 1909. 73*. Oxybelus lamellatus bicolorisquama STRAND, 1923 Oxybelus bicolorisquama STRAND, 1923, p. 172; SONAN, 1940, p. 20. Oxybelus (Oxybelus) bicolorisquama: PATE, 1938, p. 388 (listed). Oxybelus lamellatus bicolorisquama: TSUNEKI, 1968c*, p. 26; 1971a, p. 28. Specimens examined: 2 9 5 rf, Takao, 20. VI, 7, 21. VII, 1, 23. VIII. 1907; ? 1908; 1 rf, Kagi, 10. VIII. 1907. Distribution. The nominate species is widely distributed over the S. W. Palaearctic Region and the Oriental Region. Remarks. The Formosan subspecies differs from the typical race as follows : 1. Mucro with apical incision much broader, slightly more than 90 degrees, with the sinus rounded, in the typical race the incision acuter, with sinus about 40-50 degrees. 2. Lamellae somewhat more strongly bifid, the incision between the inner and outer lobes deeper (inner lobe similarly highly raised). 3. Punctures generally slightly smaller, it is especially well defined on temple and abdominal tergites, but on sternite 2 similar. Otherwise, including the structure of the clypeus and general colouration, as in the typical race.
