segment subconically narrowed basally, nearly 1-5 times as long as subquadrate pedicellus; 

 second flagellar segment very slightly shorter and broader than the first, about 1-25 : 1. 



Puncturation on thorax not extremely dense, but narrow interspaces microscopically cross- 

 reticulate, this microsculpture partly obliterated on disc of scutellum; pubescence short but 

 conspicuous, whitish. Pronotum with hind margin slightly arched, finely carinate but 

 premarginal carina not very distinct ; carina of lateral margin reaching slightly beyond middle ; 

 lateral panel with distinct longitudinal depression. Mesoscutum posteriorly with slight 

 submedian depressions continuing forwards as vague notaular furrows. Scutellum nearly 1-3 

 times as broad as long, rather flat; row of punctures along hind margin hardly deeper than 

 elsewhere, interstices longitudinally strigose. Dorsellum strongly transverse-crescentic, 

 margin finely carinate, middle slightly swollen, rather shiny, but broad alveolae along anterior 

 and posterior margins. Propodeum in middle nearly 3 times as long as dorsellum, 0-65 of 

 scutellum, 1-3 times as long as distance between median carina and plica posteriorly; median 

 carina higher in middle, with adjacent hairs directed sidewards. Upper mesopleurum and 

 metapleurum regularly punctured with interspaces smooth, generally about one-third as broad 

 as punctures. Hind coxa with broad streak, narrowing caudad, of extremely dense punctura- 

 tion and silvery pubescence below lateral edge; depression extensively punctured anteriorly, 

 punctures sparser above and reaching lateral edge only basally; impunctate area in lower half 

 transversely striate, postero-dorsally smooth, dorsal tooth low, weak; dorsal edge hardly 

 narrowing posteriorly. Hind femur rather densely and finely punctured, interspaces without 

 distinct sculpture. Fore wing: stigmal vein clavate, terminal processus broad, much shorter 

 than uncus; pubescence rather dense but basal cell partly bare. 



Gaster very slender (Text-fig. 249), hardly constricted behind first tergite, apical part broadly 

 fusiform. First tergite about 2-1 times as long as broad, with narrow smooth median carina, 

 otherwise very densely punctured, punctures sparser near to small basal fovea. Second tergite 

 partly exposed at sides. Third tergite very short, its hind margin angulate. Fourth tergite 

 medially raised into a broad finely grooved keel, sublaterally broadly weakly depressed; hind 

 margin angulate at slightly less than 90 degrees; median length nearly 0-7 of maximum width of 

 tergite. Fifth tergite broadest near middle, regularly convex or with slight cross-depression, 

 densely punctured, interspaces at most 0-25-0-30 as broad as punctures, with shallow micro- 

 scopic reticulation ; ovipositorial furrow nearly reaching apex of fourth tergite, its sides lowered, 

 only posteriorly subcarinate. Ovipositor slightly ascending (Text-fig. 250), 1 -15-1-20 times 

 as long as hind tibia.

$. 8 mm. Piceous black; with pale yellow: scape, transverse rhomboid spot anteriorly 

 and narrow interrupted line posteriorly on pronotum, medially interrupted band on fourth 

 tergite, band at hind margin of fifth tergite dorsally and large ventrobasal spot on hind femur. 

 Wings dark brown. 



Head nearly as broad as pronotum posteriorly, in dorsal view 2-1 times as broad as long; 

 temples extremely short; frontal protuberances appearing high in slightly posterior view, in 

 lateral third strongly sloping towards eyes; eye orbit rather deeply excised (Text-fig. 251). 

 Vertex convex, but depressed between lateral ocellus and eye, slightly so also at median ocellus, 

 concave between median ocellus and protuberance; punctures mostly separated by transverse
