43. Ectemnius (Hypocrabro) horvatovichi sp. n. çf $ (Figs. 24, 26) Closely allied to E. (H.) schlettereri (KOHL), but is different from this in the form of the clypeus ( 9 çf, Figs. 24, cf. Fig. 25, both in 9 ) and in the state of swelling and punctuation of the abdominal tergites. çf. Length 7.5—8.5 mm. Very similar to the male of E. schlettereri. Yellow are antennái joint 1, medially interrupted band on collar, tubercles, a narrow band on postscutellum (sometimes lacking), a large transverse (slightly oblique) mark on each side of tergite 2 (with interspace less than as wide as the mark), similar but narrower and shorter ones on tergite 3 (sometimes lacking), a band on tergites 4 (sometimes medially more or less interrupted) and 5, base and outer side of all tibiae and greater part of mid and hind basitarsi. Insides of tibiae usually black, often ferruginous, tibial spurs ferruginous, fore tarsi dark brown. Clypeus thickly covered with appressed silvery hair. Clypeus: Fig. 26 (cf. Fig. 27, in E. schlettereri, çf). Each tergite of abdomen in lateral view slightly more roundly raised than in the compared species, with the apical marginal area more distinctly depressed. Upper frons on lateral areas longitudinally closely rugoso-striate (in E. schlettereri variable, sometimes striate, sometimes not). Punctation of abdomen is considerably variable in E. schlettereri and cannot be compared in regard to the density or size, but it can generally be said that the difference in size of punctures on tergites 1 and 2 comparatively smaller in the present species than in E. schelettereri. Otherwise (including the structure of the antennae) as in the compared species. 9. Length 9.5. mm. Besides the yellow marks described on çf, mandibles externally on about basal half yellow, antennái joint 2 on outer side and a band at base of scutellum also yellow (constant?), tibial spurs more yellowish and fore and middle tarsi wholly dark brown. Appressed hair on clypeus distinctly brassy yellow (in E. schlettereri variable from silvery to brassy). Clypeus: Fig. 24 (cf. Fig. 25, in E. schlettereri), posterior depression of each tergite more marked than in çf, punctures on upper frons fine and dense, not rugosostirate. Holotype: çf, Prov. South Pyongan, Pyongyan, Hotel garden, 7-8. VIII. 1971. (No. 150). — Paratype: 1 9; Prov. do., Bongwa-ri, 45 km E from Pyongvan, 16 — 17 VIII. 1971 (No. 181). Other specimens: 3 çf, the same place as in the paratype, 16. VIII. 1971 (No. 176) (with the colour heavily changed by the cyanide vapour). Pigs. 24 — 27. — Figs. 24, 26. Ectemnius (Hypocrabro) horvatovichi sp. n. çf 9 : 24 = 9» clypeus, 26 = çf, clypeus. — Figs. 25, 27. Ectemnius (Hypocrabro) schlettereri (KOHL) çf 9 : 25 = 9 5 clypeus, 27 = çf , clypeus.
