HARIS A.: SAWFLIES FROM SAKHALIN AND THE KURIL ISLANDS 193 Heterarthrus aihinoensis spec. nov. Female. Body black. Yellow: labrum, front margin of clypeus, wide inner orbits, small spots around the bases of antennae, most of tegulae. Antennae entirely black. Legs yellow. Black: coxae, except their apices, basal half of all femora. Wings infuscated up to the middle of the stigma. Stigma and venation dark brown. Head, thorax and abdomen smooth and shiny. Clypeus truncate. Genae long, about 2x longer than the diameter of front ocellus. Antennae with 11 joints. Ratios of the antennái joints: 7 : 4 : 18 : 14 : 13 : 12:9.9.7:7:8. Antennae short. Length of an antennae : length of the costa = 7.11. Head behind the eyes only slightly contracted. OOL :POL : OCL =8:10:7. Frontal space without pentagonal area but divided into 2 parts by a longitudinal furrow. Number of cubital cells: 3. Hind wing without closed middle cells. Anall cell of hind wing missing. Sawsheath long and paralell (Fig. 8). Claws with narrow and small inner tooth. Length: 5.0 mm, length of fore wing: 5.2 mm. Holotype: female: Kuril Islands, Kunasir isl., Aihino, 30. 07. 1973. The new species closely related to Heterarthrus ochropoda (Klug, 1814). H. ochropoda has short and apically widened sawsheath with long curved hairs (Fig. 7), antennae with 12-14 segments. The new species has long and paralell sawsheath with short hairs and antennae with 11 segments. Masaakia kichizoi spec. nov. Female. Body black including antennae and mouthparts. Tegulae and a very small inner triangular angles of genae yellow. Legs yellow, bases of all coxae and inner half of all femora black. Wings subhyaline, very slightly infuscated. Venation and stigma brown. Head contracted behind the eyes. Temples and vertex without postoccipital carina. OOL : POL : OCL = 11:7:7. Genae about half as long as the diameter of front ocellus. Clypeus widely but slightly emarginated. Clypeal emargination about l/3x as deep as the clypeal median length. Inner margines of eyes paralell. Middle supraantennal fovae large and elongated. Lateral supraantennal fovae rounded and about as large as the front ocellus. Ratios of the antennái segments: 7 : 3 : 22 : 18 : 18 : 15 : 13 : 12 : 13. Pedicell wider than long. Radial crossvein and third cubital crossvein interstitial. Radial crossvein of fore wing straight. Fore wing with 4 cubital cells. Anal vein of fore wing straight. Hind wing without closed middle cells. Head shining, unpunctured, with very fine undefined surface sculpture. The whole thorax smooth and shiny. Abdomen shiny with very fine hardly visible surface sculpture on the tergites. Eighth abdominal tergite with yellowish semicircular membraneous area. Sawsheath elongated, apically narrowed, rounded at the apex (Fig. 11 and 12). Cerci very short. Length: 7.2 mm, length of fore wing: 7.0 mm. Holotype: female: Kuril islands, Kunasir island, Tretjakovo. 05. 08. 1973. Paratype: female: topotypic.
