54 Z. BOUCEK 



low, with weak carina diverging on either side of median ocellus; vertex punctured and hairy 

 except laterad of each ocellus, there with some radiating striae ; fine groove laterad and anterior 

 to median ocellus, latter separating it from distinct scrobal carina. Frontal protuberances 

 low; interantennal lobe carinate only above. Head in facial view 1*27 times as broad as high, 

 densely clothed with moderately long hairs. Relative measurements: height of head 49*5, 

 width of frontovertex 33*5, lower face 31*5, eye 35*0 : 22-5, malar space 8-5, mouth width 25. 

 Inner orbit weakly but distinctly emarginate. Clypeus about i-i times as broad as high, 

 subtriangular, lower margin with semicircular lateral lobes and small median tooth. Inner 

 edge of mandibles, above the triangular notch, subemarginate. First flagellar segment 1-35, 

 second 1 -4 times as long as broad. 



Thorax densely punctured, hairs semi-erect, thin, of medium length. Pronotum with two 

 rows of punctures between premarginal carina and the hardly raised and nearly straight hind 

 margin, sides in dorsal view straight, slightly converging. Mesoscutum shallowly depressed 

 submedially, very narrow interstices with weak microscopical cross-striation. Scutellum fairly 

 flat, 1 "56 times as broad as long (excluding axillae). Dorsellum transversely crescentic, about 

 3:1, weakly convex, with crowded punctures bearing weak sparse hairs, apically in middle 

 subcarinate. Propodeum medially (sculptured part) shorter than dorsellum, median carina 

 indistinct, plicae conspicuous only posteriorly. Upper mesopleurum with regular puncturation, 

 rather narrow interspaces smooth. Fore femur dorsally with blunt edge, tibia nearly rounded 

 but ventro-externally carinate. Depression of hind coxa above lateral edge with a streak of 

 crowded puncturation ; hairs directed towards lateral edge but nearer to the edge more towards 

 apex. Hind femur densely coarsely punctured; hind tibia also rather coarsely and not very 

 densely punctured, apex with narrow spine. 



Gaster (Text-fig. 50) nearly i«a times as long as rest of body, 2-5 times as long as broad, 

 slightly broadened posteriorly (width of first and fifth tergites as 1-2 : i-o; pubescence uniform, 

 not forming fasciae. First tergite medially with broad impunctate ovipositorial furrow, 

 otherwise 1-2 times as long as broad. Hind margins of third and fourth tergites subangulate, 

 the fourth about 4 times as broad as long, medially flat, with about 5 transverse rows of punc- 

 tures; fifth medially 0-41 as long as the first. Ovipositor reaching scutellum, apex of sheaths 

 rounded.

9- 9-5-1 1 -5 mm. Black with faint metallic violaceous tint; lemon-yellow are: spot on 

 scapus, narrow line posteriorly on metapleurum, upper edge and apex of hind coxa, narrow line 

 along ventral edge of hind femur and mainly hind half of gaster, with black reduced to anterior 

 half of fifth tergite, a narrow line at its hind margin, a dot around spiracle and black line at 

 hind margin of sixth tergite, epipygium on both anterior and posterior (ovipositorial) margin 

 and a median streak from below up to level of spiracle. Upper edge of hind femur and tibia 

 apically often brownish. Fore wing yellowish brown, hind wing subhyaline except at front 

 margin. 



Head hardly narrower than pronotum, dorsally about 2-3 times as broad as long; occipital 

 carina touching lateral ocelli ; temples distinct though not carinate, slightly longer than diameter
