Underside of antennae somewhat brownish-black. Mandibles, maxillary and labial palpi, posterior margin of humeral angles, apex of all coxae, all trochanters, femur, tibia and basitarsus of fore and mid-legs, apex of hind femora, base of hind tibiae, tibial spurs of all legs dark yellowish or pale brownish-yellow. Basal portion of fore femora, upperside of mid-trochanters and -femora, four apical segments of mid-tarsi brownish. Pulvilli brownish-black. Anterior margin of clypeus, posterior margin of pronotum, tegulae, posterior margin of each abdominal segment pale brownish in coloration. Wings transparent, slightly clouded, violaceously reflecting in certain aspect, nervures and stigmata brownish-black. Clypeus and lower half of front densely covered with appressed silvery pubescence. Body finely covered with minute greyish pubescence. Abdominal sternites with some erect, comparatively long, greyish hairs. Head very densely and minutely punctured. Mesothorax also microscopically and more minutely punctured. Enclosed area of propodeum distinct, with a broad, longitudianal impression, which is more or less transversely striated, caudal slope of propodeum also with a median, broad, longitudinal, deep impression. Very slender species. Head slightly broader than long, with inner margins of eyes slightly narrower at the clypeus than at the vertex. Clypeus broad, slightly less than twice the length of it, with the anterior margin rounded and slightly produced at the middle, and the produced portion is moderately notched at the middle. Front with a distinct longitudinal carina between and above the insertions of antennae and with a median, longitudinal impression below anterior ocellus. Ocelli put in a triangle, distance between anterior and posterior ocelli than postocellar line. Oculo-ocellar line : postocellar line=1 : 2. Head, seen in profile, with temples very much narrower than eyes. Antennae slender, long, and filiform, each segment distinctly longer than wide ; third segment the longest, about as long as the two basal segments put together ; fourth slightly shorter than third ; fifth slightly shorter than fourth. Thorax long, more than twice as long as broad. Mesonotum with a median, longitudinal, impressed line. Abdomen very slender. First segment or petiole of abdomen about as long as or slightly longer than the three following segments put together, longer than hind tibia and basitarsus put togethre, slender and claviform near the apex. Measurements (20 units=1mm) Length ; Head+thorax 60 Abdomen 98 Petiole of abdomen 46 Fore wing 95 Hind wing 78 Width : Head 27 Thorax 24 4th abdominal tergite 16 Habitat : Japan (Kyushu). Holotype : 1♀, 14. vii. 1938, Yoshiwara, at the foot of Mt. Inugadake, Buzen, Kyushu, the author leg., in the collection of the Kyushu Imperial University.
