, "Collected in Malaise trap" (Washington, USNM). - Distribution: Illg. Sri Lanka. The significant characteristics of the new female are as follows. Length 5 mm. Similar to male in colour, abdominal segment 3 rufous only distally (as in male), antennái joints yellowish brown excepting brown upper side of 5-13 and tips of 3-4, legs lighter brown, upper side of fore femora, middle and hind femora, as well as tibiae largely and tegulae brown. Wings, hairs as in male, lateral margins of tergite 1 with a loose tuft of white hairs (figs 27 6*, 30 o_). Antennae with very short white hairs. Head (including eyes) only slightly longer than broad (49 : 45), gradually converging behind eyes (cf. fig. 26 c"), eyes separated from occipital carina by about its own length (12); occipital carina narrower than in male; frons, ocelli similar to male, POL:OOL = 6:9; eyes longer than broad and separated from mandibles by two-thirds the length of eye (12 : 19); flagellar joints 5-7 slightly thickened medially, scape three times longer than joint 2, latter hardly shorter than 3, 2-3 nearly twice longer than joints 4-12, latter joints broader than long, length (and breadth) proportions of antennái joints 1-13 = 22(6): 7(4): 8(5): 4,5(5.5): 3.5(5): 4(6): 4(6): 5(6): 4(5): 4(5): 4 (5): 4(5): 6(4). Pronotum only 1.46 times broader than long (35 : 24) (fig. 29), anterior corners with less sharp angles than in male, otherwise similar to male. Longitudinal furrow of mesonotum slightly deeper and narrower and scutellum with not so large punctures. Propodeum shorter than half diameter of disc transversally (17 : 23), lateral area (fig. 30) narrower than in male (fig.

25), lateral margins of propodeum distinctly divergent, spines longer, about two-thirds the length of propodeum medially (12 : 17), spines acute also in lateral view. Tergite 1-2 (figs 30-31) corresponding to male, i.e. tergite 1 unusually rather densely and deeply, laterally more densely punctured, also tergite 2 with very dense and deep punctures. P. hirashimai is related to krombeinicus, P. densepunctatus Móczár, 1971, P. brevialatus (Benoit, 1968) and P. peringueyi (Kieffer, 1913). It differs from krombeinicus by the characters given in the key; from densepunctatus chiefly by tergite 2 where interspaces between punctures not shagreened, shining ( o_ ); from peringueyi and brevialatus by not at least pronotum, mesonotum not red, lateral spines of propodeum not half as long as propodeum (o_). Male differs from densepunctatus and from peringueyi by head not black, pronotum, mesonotum and scutellum not yellowish red, etc. This species is similar in colour to Sulcomesitius wahisi sp.n., but differs by the coarse and scattered punctured of tergite 1 and by the long lateral spine of propodeum (not 9 : 20), etc. Remarks. This species was decribed as Heterocoelia on the basis of the obscurely margined, shallow, moderately shining compression at posterior third of mesonotum and owing to the rather obtuse lateral spines of propodeum only in lateral view (in paratype more acute). By discovering the female of this species, owing to the unusually dense and deep punctures of the tergites, it
