wide and than 10th, club ca. 1.2 to 1.3 times longer than joints 3 to 8 and 1.4 to 1.5 times longer than joints 1 and 2 taken together. — Pronotum extremely finely and sparsely punctured and finely shagreen, 2.1 to 2.3 times as wide as long, broadest at base, laterally much roundly narrowed forwards. — Scutellum short, transversely triangular, finely punctured. Elytra on the base as wide as pronotum, broadest at anterior third of their length, backward more or less roundly narrowed, 1.55 to 1.6 times longer than wide. — Base of elytra finely and less densely punctured than their apical half (still considerably more densely and coarsely than pronotum). — Legs rather short, procoxae narrowly divided by a prothoracic triangular process reaching to posterior third of their length; mesocoxae narrowly divided by a triangular mesothoracic process exceeding a little a half of their length. Metatibial spurs long, slightly different in length, longest one reaching approximately to terminal quarter of first tarsal joint which is very large, much longer than tibia and considerably longer than joints 2 to 4 taken together; joints 2 and 4 subequally long and each 1.4 to 1.5 times longer than 3rd; claws simple, well enlarged basally. — Metathorax laterally rather finely and moderately densely punctured and transversely shagreen. Median depression of metathorax very narrowly lanceolate, not reaching as far as anterior third of metathorax length. Metepisterna well developed, triangularly narrowed backward, 3.3 times longer than wide at anterior border. Abdomen punctured more densely than metathorax. Aedeagus as depicted (Fig. 19). 2.1 to 2.3 mm long. Microscapha mutabilis sp. n. Localities: New Guinea (NE), Mt. Wilhelm, 3900 m, çf (holotype), - 13-24. 09. 1968, leg. J. BALOGH. — Same locality, 1 çf (paratype) — 7-8. 08. 1969, leg. J. BALOGH. The holotype and paratype have been deposited in the Hungarian Museum of Natural History, Budapest. Description: Body oblong-oval, 2.1 to 2.2 times longer than wide, more or less convex, elytra posteriorly along suture somewhat flattened. Colour black-brown or brown, prothorax, partly abdomen and legs, usually antennái joints 1 to 6 and apex of 11th or antennae completely, maxillary palpi, as well as two large transversal curved falcate paramedial spots in front of pronotal base, often a transverse band behind anterior border of pronotum, and variable spotted markings on elytra (Figs. 1, 2), light reddish-brown to reddish. Body clothed with thin decumbent grey-yellowish pubescence, upper surface more or less shining. — Head rather sparsely punctured with punctures of moderate size. Eyes large, rather coarsely faceted, anteriorly deeply emarginated; distance between eyes 1.4 to 1.5 times less than their height. Maxillary palpi 4-jointed, 2nd joint oblong, distinctly longitudinal, much longer than 1st and 3rd, latter approximately as long as wide; joint 4 large, roundly securiform or irregularly oval, roundly obliquely truncate at apex, not less than 3 times longer and ca. 2.2 to 2.5 times wider than 3rd one. — Antennae (Fig 16) rather short, exceeding a little base of elytra; club poorly developed, 3- to 4-jointed; antennái joints 1 and 2 well developed, longitudinal, 2nd a little longer than 1st, about twice wider and 1.8 to 2.0 times longer than 3rd, latter joint small, slender, distinctly longitudinal, much longer than 4th or 5th one, latter two being subequal and very slightly transversal; joint 6 a little broader than 5th, slightly transversal; joint 6 a little broader than 5th, slightly transversal; joint 7 considerably wider and longer than 6th; joint 8 approximately as long as wide, distinctly broader than 7th; joints 9 to 11 forming a loose club poorly separated from joint 8 (which may seem to gain the club); 9th slightly longitudinal, 1.2 to 1.3 times wider and 1.5 times longer than 8th; joint 10 usually as long as wide; 11th more or less oval, 1.4 to 1.5 times longer than the 10th one, joints 9 to 11 ca. 1.7 to 1.8 times longer than 1st and 2nd, and 1.2 to 1.3 times longer than joints 3 to 8 taken together. — Pronotum much transversal, 1.9 to 2.0 times wider than long, broadest at base, distinctly roundly narrowed forwads, extremelly finely and sparsely punctured. — Scutellum short, transversely triangular. — Elytra more or less oblong-oval, 1.7 to 1.75 times longer than wide, broadest at anterior third of their length whereupon backward roundly narrowing, surface finely transversely shagreen and finely and rather densely (considerably denser and coarser than on pronotum) punctured, distance between punctures at basal part of elytra ca. 1.1 to 1.3 times greater than diameter of a puncture. — Legs rather short ; procoxae divided by a triangular prothoracic process reaching around the posterior third of their length; mesocoxae divided by a triangular mesothoracic process reaching to posterior third of their length; mesotarsal joint 1 elongate, approximately as long as joints 2 to 4 taken together, but considerably shorter than tibia. Metatibial spurs long, reaching to about terminal quarter of length of metatarsal joint 1, which is very long, much longer than tibia and nearly as long as all subsequent joints taken together; joints 2 and 4 subequally long, each 1.5 to 1.6 times longer than 3rd; claws simple, distinctly enlarged basally. — Metathorax laterally moderately densely punctured with punctures of medium size; distance between punctures subequal
