67): heath (Calluna) litter and soil (with part of Formica nest!), Körmend, 5 Sept., 1967, leg. P. AGÓCSY; 6 ex. (Paratypes: A— 136p—

67) : data as for Holotype. One Paratype in the collection of Dr. K. SAMUINAK (Praha), Holotype and other Paratypes in the Zoological Department of the Hungarian Natural History Museum, Budapest. Anoetus oralis (J. MÜLLER, 1860) It was only this species which occurred on Ips sexdentatus, always in very large numbers. In one case I found it also on Ips cembrae.

Anoetus pannonicus sp. n. Length: 139 p., width: 101 p.. Dorsal side (Fig. 3): Apex of notocephale wide, lateral sides behind it finely concave then convex. Base straight. Both notocephalic hairs minute, inner pair originating somewhat anteriorly to outer pair. Notogastral hairs minute. Ventral side (Fig. 4) : Gnathosoma short, wide, only 1/3 longer than wide. Margins throughout convex, gradually narrowing distally. Terminal hairs long. On two sides of gnathosoma and behind coxa 2 an unusually strongly chitinized point each. Sternum and epimeres 2 terminating free. Epimeres 3 more weakly developed than usual, reaching one another medially only by attenuating to a degree. Ventrum terminating free. Coxal areas 1, 3, and 4 with a strongly developed suctorial disk each. Suctorial plate large, one and a half times wider than long ; all suctorial disks strongly developed. Legs: Femur of leg 1 (Fig. 9) short. Tarsus long, adhering hair small, short-stalked. "Tarsal group" of 4 members, sensory hair (<p) only slightly longer than half length of tarsus. Solenidium of tarsus long, apically arcuate, tibial co

2 strongly incrassate apically, clavate, shorter then co

v Solenidium of leg 2 (Fig. 8) longer than sensory hair. Legs 3 and 4 (Fig. 10—11) simple, terminal hairs short. Type-material: 1 ex. (Holotype: A—137p —

67): Sifófok (Dryocoetus villosus), leg. F. LICHNECKERT. Remarks: On the basis of the suctorial disks of the coxal areas, and the configuration of the epimeres and legs, the new species is relegable to the genus Anoetus. The dorsal hairs are short, but the shape of the gnathosoma and the epimeres indicates an alliance with the members of the dryocoeti-gronp. The large suctorial disks also refer to this relationship. From the species comprising this group, the new taxon can be distinguished by primarily the short dorsal hairs and the peculiar development of epimeres 3. This latter, as well as the extraordinary co

2 and the robust chitinous apices arising near the gnathosoma, separate it from all known congeners. Anoetus pini (SCHEUCHER, 1957) Locality: Siófok (Hylastes ater). Leg. F. LICHNECKERT. Anoetus vitzthumi (SCHEUHER, 1957) Localities: Tarkő, Mts. Bükk (Dryocoetus autographus

), 10 April, 1967, leg. S. MAHUNKA; Mt. Paring, Transylvania (Dryocoetes autographus), 29 July, 1956, leg. S. ENDRŐDY-YOUNGA.
