thickening slightly distad, its first segment usually 1-5 to i-6 times as long as broad, but quad- 

 rate in small specimens, the following segments subquadrate or some of the distal ones very 

 slightly transverse ; clava fully twice as long as broad, about as long as two and a half funicular 

 segments ; flagellum with rather conspicuous and somewhat outstanding bristles ; sensilla 

 not very numerous. 



Thorax barely 1-5 times as long as broad. Mesoscutum 1-7 to i-8 times as broad as long, 

 shiny, with fine delicate reticulation which is for the most part engraved ; mid lobe fairly 

 thickly hairy, the hairs rather long ; notauli deep, slightly curved. Scutellum about as long 

 as mesoscutum, slightly longer than broad, strongly convex in the transverse axis, with sculpture, 

 excepting the frenum, rather finer than that of the mesoscutum ; four to five pairs of bristles ; 

 frenum marked off by a distinct line ; scutello-axillar sutures converging strongly and curving 

 round so as to meet ; the scutellum therefore touches the mesoscutum only on a narrow base. 

 Dorsellum about one third as long as the frenum. Propodeum about as long as the frenum, and 

 about one third as long as the whole scutellum, shiny with very weak alutaceous sculpture ; 

 median carina virtually obsolete, though the propodeum is raised in a roof-like manner in the 

 middle ; plicae absent ; spiracles suboval, not quite touching the metanotum ; callus with 

 four to five bristles. Metapleuron, and mesopleuron except the smooth subtriangular dorsal 

 area, shiny with fine delicate and hardly raised reticulation ; mesepimeron distinctly marked 

 off, nearly three times as long as broad ; mesosternum shiny, with subobsolete sculpture, 

 mesolcus distinctly impressed. Postspiracular sclerite with rather coarse, slightly raised, 

 reticulation. Legs somewhat slender ; hind coxae nearly 2-5 times as long as broad, shiny, 

 with not very fine longitudinally strigose-reticulate sculpture, which is very slightly raised above 

 the general surface, the dorsal surface of the coxae with some hairs ; spur of mid tibia slightly 

 more than two thirds the length of the first tarsal segment. Fore wing slightly more than twice 

 as long as broad ; costal cell broad (eight to nine times as long as broad), its lower surface 

 fairly thickly hairy, its upper surface with a row of numerous hairs in the distal half and with 

 several additional hairs below this row in the distal third ; basal cell with scattered hairs over 

 its distal third to half, and partly closed below by a line of hairs ; speculum small, reduced to an 

 oval area below the parastigma and not reaching the cubital vein ; wing beyond the speculum 

 quite thickly hairy ; veins rather thin, the postmarginal nearly or quite as long as the marginal 

 vein, which is 1-7 to i-8 times as long as the stigmal vein, the latter slightly curved ; stigma 

 rather small, oval, slightly longer than high, with a long uncus. 



Gaster lanceolate, including the ovipositor sheaths 1-35 to 1-5 times as long as head plus 

 thorax, usually strongly compressed and much narrower than the thorax ; sunken dorsally 

 beyond the basal tergite, the latter with a subtriangular basal fovea ; ovipositor sheaths, as 

 seen in dorsal view, projecting beyond the apex of the gaster by a length varying from about one 

 quarter to nearly one third that of the hind tibia ; hypopygium extending distinctly less than 

 half way along the gaster. 



o*. Unknown. 



The female of coniferae sp. n. closely resembles that of vulgaris Walker, which 

 differs as follows : 



Fore coxae mainly to entirely metallic, at most with an indefinite pale stripe 

 along the inner aspect ; all femora more or less infuscate, at least basally. Gaster 

 shorter, ovate to ovate-lanceolate, including ovipositor sheaths from hardly longer 

 than the thorax to slightly longer than head plus thorax, less compressed and as 

 broad as or broader than high, only slightly narrower than the thorax, sometimes 

 not narrower ; ovipositor sheaths rather less exserted.
