REVISION OF LEUCOSPIDAE 207 



coxa fairly slender, dorsal densely hairy face nearly as broad as depression which is rather 

 narrow, not very densely punctured, with (partly impunctate) streak of sparser coarser 

 punctures below dorsal edge; posteriorly with slight oblique raised carina instead of auricle, 

 indicating an improper dorsal tooth. Hind femur very slender (Text-fig. 237), with very large 

 basal tooth and slender, well separated smaller teeth. Hind tibia with externo-ventral carina 

 extending over three-fifths of length, apex slightly produced into a broad spine, outer spur 

 short. Apical processus of stimal vein of fore wing about half as long as uncus. 



Gaster strongly clavate, constricted at hind margin of first and fifth tergites, then sub- 

 acuminate; therefore of a rather unusual shape (Text-fig. 238); pubescence extremely short. 

 First tergite 1 -34 times as long as broad, dorsally convex, posteriorly with median impunctate 

 streak, apical margin and basal fifth also impunctate. Third tergite very densely and much 

 more finely punctured than the first or fifth tergite; hind margin straight. Fifth tergite most 

 convex laterally in the middle and dorsally at anterior end of the deep and steeply ascending 

 ovipositorial furrow, ending 1 -5 times length of fourth tergite from its apex. Sixth tergite 

 visible dorsally, with raised spiracles. Ovipositor sheaths slightly longer than hind tibia.

Holotype $, New Guinea: Territory of New Guinea, 6 km \V. of Wau, Nami 

 Creek, 1700 m, 10.vi.1962 (/. Sedlddek) (BBM, Honolulu). 



A very distinctive species, named in honour of its collector. The colour and 

 the shape of the body of L. sedlaceki reminds one very much of L. antiqua Walker 

 from New Caledonia but morphologically the species is much closer to L. aruina 

 Walker. 



Leucospis niticoxa sp. n. 



(Text-figs 241, 242) 



9- 11*5 mm (slightly curved: 11 mm). Black with steel-bluish tint most distinct on thorax; 

 yellow pattern: arcuate bands on pronotum anteriorly and on scutellum posteriorly, equally 

 broad even in middle, mesoscutum with lateral lines and submedian round spots, broad spots 

 on upper mesepisternum and on metapleurum, a cross-band just behind middle of first tergite 

 broader laterally and interrupted medially, narrow band on middle of fifth tergite, sixth tergite 

 with dorsal transverse spots and smaller spots behind each spiracle, hind coxa apically on 

 lateral and ventral edges, hind femur with larger suffused yellow streak dorso-apically and smaller 

 one at teeth; otherwise legs except coxae reddish, knees and fore and hind tibiae dorsally 

 yellow. Wings weakly infuscate, venation rather pale. 



Morphologically similar to L. sedlaceki as described above, with mainly the following dif- 

 ferences. Head dorsally 2-5 : 1; occipital carina sublaterally splitting into several carinae 

 uniting again into one on upper temples; POL : OOL as 12 : 9. Head in facial view 1-21 

 times as broad as high; face extremely densely finely punctured-rugulose; pubescence very 

 short, dense, pale brassy. Relative measurements: height of head 73, width of frontovertex 

 44, scrobes 28, lower face 42, its height 37, eye 49 : 32, malar space 17, width of mouth 33, 

 scapus 24 ; flagellum plus pedicellus fully 1 -3 times as long as breadth of head. 



Thorax with puncturation moderately coarse but very dense, dull, narrow interstices distinctly 

 though extremely finely granulate-reticulate. Dorsum less convex than in L. sedlaceki. 

 Lateral panel of pronotum above nearly smooth on bottom, deeply depressed just below strong 

 lateral edge of collar. Mesoscutum: notaular lines indistinct. Scutellum 1-4 times as broad 

 as long; impressed marginal groove with crenulae converging obliquely towards median line. 

 Dorsellum in front of marginal broad crenulate furrow with fiat disc very finely rugulose. 

 Median carina of propodeum very high, highest at one-third, shorter than its distance posteriorly 

 from plica. Fore femur laterally flattened, shiny, ventrally distinctly edged; fore tibia
