times as long as greatest width before its end, gradually widening posteriorly and rounded behind. Tergite 2 subquadrate, somewhat wider at its anterior margin than long. Excavate fore half of 1st tergite almost indistinctly striated, otherwise every tergite and sternite smooth and shiny. Ovipositor sheath and ovipositor nearly twice as long as body, 9-9,5 mm. Body reddish yellow, abdomen rather light reddish yellow. Antenna brown to dark brown. Margin of clypeus, subclypeus, and rostrum brown, palpi brown to light brown. Ocellar field black, vertex and occiput more or less brownish. Propodeum, meso- and metasternum brown to blackish brown. Last tergite dark brown. Ovipositor sheath blackish brown. Legs rather yellow. Coxae 2, tronchanters 1-2 weakly brownish fumous. End of tibia 3 blackish, tarsi 2-3 dark fumous. Wings brownish fumous. Veins brownish yellow pigmented. 6* similar to female, however, differs in the following features: Body 4-4.5 mm long. Antenna 26 jointed. Tergite 1 more strongly widening posteriorly, only 1.4 times as long as its greatest width before its end. Tergite 2 transverse, its hind width onethird greater than its fore width, its length shorter than fore width (16-18:22-24). Dark colour more extended. Mesopleura, mesosternum, metanotum, propodeum, metathorax, and last five abdominal segments blackish brown. Host unknown. Localities: 1. Spalato (=Split, Dalmatia), 1914, 2 ^ and 1 o (1 j holotype, 1 6* allotype, 1 o paratype), leg. HORVÁTH. - 2. Cavtat, Dalmatia, Aug. 1906, 1 <j> (paratype), leg. HORVÁTH. - 3. Igalo, Dalmatia, Aug. 1906, 1 S (paratype), leg. HORVÁTH. Holotype (Hym. Typ. No. 2336), allotype (Hym. Typ. No. 2337) and paratypes (Hym. Typ. No. 2338-2340) are deposited in the Hungarian Natural History Museum, Budapest. The new species seems to be closely related to Agathis tadzhica TEL. (USSR: Tadzhikistan), but differs from it as follows: Agathis tadzhica TEL. 1. Cheek longer than vertical diameter of eye. 2. Prescutellar furrow narrow, with weak crenulation. 3. r 2 straight, areola (Cu 2 ) sessile. 4. Propodeum weakly rugose. 5. Tergite 2 transverse, wider anteriorly than its length. 6. Ovipositor sheath as long as body. Agathis gilvus sp.n. 1. Cheek shorter than vertical diameter of eye (Fig. 2). 2. Prescutellar furrow wide (as wide as half length of scutellum), with 5 strong crenulae. 3. r 2 curved, areola more or less petiolate (Fig. 3) 4. Propodeum vermiculate rugose. 5. Tergite 2 subquadrate, slightly wider anteriorly than its length (Fig. 4.) 6. Ovipositor sheath nearly twice as long as body. Agathis syngenesiae NEES (Europe, Asiatic USSR) is another species near to A. gil vus sp.n., however, the differences between them are few and sufficient to warrant the specific value:
