Agathis genualis MARSH. Very near to A. longicauda KOK, (see below). The main difference between the two species seems to be limited to antenna (TOBIAS 1963): A. genualis MARSH. A

.longicauda KOK. - Antenna as long as head, thorax and - Antenna as long as body, abdominal segments 1-2. - Antenna 22-26 jointed (Yugoslavian - Antenna 27-31 jointed (Yugoslavian female with 26 joints). female with 28 joints). Widely but rather sporadically distributed in the Palearctic Region. New to the fauna of Yugoslavia. Locality: Montenegro (=Crna Gora), áabljak, 1400 m, 30 June 1958, 1 o_, leg. MIHÁLYI. Agathis gilvus sp.n. od*' (Figs. 1-4) 0. Body 5 mm long. Head transverse, twice as broad as long (from above), as broad as high (in front, Fig. 1). Eye somewhat protruding from outline of head, tempóra behind eyes (from above), rounded, constricted. Ocelli on a high triangle, distance between fore and a hind ocelli longer than diameter of latter (5:3), distance between hind two ocelli twice as long as diameter of an ocellus; POL=OOL. Occiput strongly sinuate. Vertical diameter of eve longer than cheek (22-24; 20, in lateral view, Fig.

2). Rostrum about as long as cheek, maxillar palpi somewhat longer, labial palpi shorter than cheek. Head polished, face with extraordinary very fine punctation, perceptible at x50-60. Antenna shorter than body, 4 mm, 25 jointed, flagellar joint 1 nearly 4 times as long as wide, further ones gradually shortening and hardly attenuating so that penultimate joint 1.5 times as long as wide. Thoracic length, height, and width as 65-68:40-42:23-25. Head broader than thorax (30-32:23-25). Thorax, except propodeum, polished. Parapsides evenly deep, finely crenulated, meeting each other on hind half of mesonotum and continuing in a short median furrow not reaching prescutellar furrow. Prescutellar furrow wide, with 5 crenulae. Propodeum vermiculate rugose, weakening to its anterior-lateral thirdfourth, its declivous part (laterally from carina) subrugulose. Twomedio-longitudinal carinae distinct but weak. Sternauli narrow, deep, finely crenulated, extending on posterior half of mesopleura and almost reaching hind marginal suture. Legs normal. Hind femur 3.5 times as long as broad. Hind tibia as long as hind trochanters and femur together. Hind tibial spurs unequal, inner one as long as onethird of basitarsus, outer one shorter. Fore wing (Fig. 3). shorter than body, 4 mm long. Metacarp slightly longer or as long as stigma. Radial vein (r) curved. Areola (Cui) three-sided and more or less petiolate (never sessile), di very short, d

2 almost 5 times as long as di. Abdomen somewhat longer than head and thorax together. Tergite 1 (Fig. 4) 1.6-1.65
