pressed and slightly obliquely truncate at apex, tergite 7 without pygidial area, but much more largely and closely punctured than on the preceding tergite, hind tibiae with a few strong spines on outer side, but much less in number than in 9 . Punctation much finer, weaker and sparser. 54. Grossocerus (Crossocerus) denticornis (Guss., 1932) (Figs. 40 — 46) Crabro (Crossocerus) denticornis GUSSAKOVSKIJ, 1932, p. 24 (rf, Ussuri). Specimens examined : 18 9 J Prov. South Pyongan, Pyongyan, Hotel garden, 4 — 31VIII. 1971 (Nos 137, 150, 157, 162, 166, 169, 176, 177, 190, 225); 1 9, Prov. do., Pyon, gyan, Nung-ra do (island), 17. VIII. 1971 (No. 182); 1 9> Prov. do., Chang-lyong san, 50 km N of Pyongyan, 17. VIII. 1971 (No. 182); 2 9 , 1 rf , Prov. do., Mts. Guk-san-bong. 10 km NE from Nam-po (No. 239). Distribution : Hitherto known only from the Ussuri region, new to the Korean fauna . Remarks. — rf. Except that the yellow or orange colour is faded into whitish the maculae well agree with the original description. Clypeus: Fig. 40, antenna! joints 3—9: Fig. 41 (slight difference from the figure given by GUSSAKOVSKIJ), coxal tooth of middle leg seen from the side : Fig. 42 (also considerably different from his figure, it is semitransparent). The form of fore femur seen from above somewhat different from that of C. exiguus, slightly more angulated and with basi-anterior half fairly strongly depressed (Fig. 43), the form of the middle femur also somewhat dissimilar (Fig. 44), fore metatarsus slightly modified, flattened, elongated, with sides narrowly lamellate, transparent (Fig. 45). Collar of pronotum without the medial incision, lateral carinae of posterior inclination of propodeum not on posterior part only, but till near stigmata distinct. Punctures on mesonotum comparatively close, with the average int espaces nearly as large as the punctures. 9 (hitherto unknown). Length 4.5—6.0 mm. Black ; pale yellow or yellowish white (under the natural condition possibly yellow) are antennái joint 1 in front and on outer side, a mark on clypeus (varying from nearly wholly to anterior third except the comparatively broad marginal brown), mandibles except apex, palpi a short band on collar, tubercles, apices of femora, tibiae at base and externally and greater part of tarsi. Antenna! joint 1 above and on inside, tegulae, trochanters, articulations of leg and tarsi apically brown or pale brown (thorax and legs much more broadly black than in çf). Head seen from above with the form as in C. exiguus, but the ocelli relatively larger (OOD:P()D = 15:11, width of postocellus relatively 8), frontal impression similar in form, but not impressed, gently elevated, with the outline indistinct, upper frons well developed, seen in profile forming a nearly right angle with the anterior frons, median furrow distinct, inner orbits as in rf, more strongly convergent below, with minimum interocular distance less than half as long as the antennái scape (joint 1), clypeus: Fig. 46, the state of trident ate apical margin more or less variable, mandibles bifid at apex, occipital carina by degress lowering and disappearing at the ends below near the buccal carina, antennái joint 3 in the broadest view twice, in the narrowest view 2.2 times as long as broad at apex, collar as in çf (not incised as in C. exiguus), propodeum similar in structure to çf, abdominal segment 1 slightly longer than wide at apex (30:25), each segment not constricted, pygidial area with lateral carinae gently curved and rounded at apex. Punctures generally slightly larger, more distinct and closer than in çf, on upper frons usually very close (more or less variable in density), on mesonotum with intervals less than as large as the punctures, but on mesopleuron finer and
