Fore wing with costal cell with a row of hairs on its upper surface, extending over about the 

 distal half of the cell, the lower surface with one complete row of hairs plus two or partial rows 

 in the distal half ; basal cell, on upperside of wing, closed below except proximally by a line of 

 hairs on the cubital vein, also with its distal quarter or so hairy ; speculum closed below, on 

 the lower surface of the wing partly effaced by several hairs below the parastigma ; disc of 

 wing rather thickly haired ; marginal vein 1-55 to 1-7 times as long as the stigmal vein, the 

 latter slightly curved, not forming a very acute angle with the postmarginal vein ; stigma 

 moderate-sized, oval. 



Petiole of gaster small, subconical, about 1 -5 times as broad as long, with some weak sculpture 

 posteriorly, otherwise smooth. 



Gaster long-ovate, as long as or usually somewhat longer than the thorax, but barely as broad 

 as the latter, acutely pointed, 2*0 to 2-4 times as long as broad ; first tergite usually occupying 

 about one third of the total length, occasionally slightly more ; last tergite a little shorter than 

 its basal breadth ; ovipositor sheaths slightly exserted ; ventrally the gaster is keeled, the 

 tip of the hypopygium situated about half way along. After death the dorsal surface of the 

 gaster tends to remain convex, though sometimes it is slightly sunken discally. 



o\ Differs from the female as follows: 



Antennal (Text-fig. 156) scape broader, 2-6 to 2-9 times as long as broad, its outer aspect 

 with a smoother and somewhat shiny boss in the upper part, extending half or slightly more 

 than half way down ; pedicellus hardly longer than broad ; combined length of pedicellus 

 and flagellum i-6 to 1-75 times the breadth of the head ; first funicular segment i-8 to 3 times 

 as long as broad, and 1-5 to i-8 times as long as the pedicellus, sixth segment 1-5 to 1-7 times 

 as long as broad ; clava 3-5 to 4 times as long as broad, somewhat longer than the combined 

 length of the two preceding funicular segments ; flagellum clothed with hairs whose length is 

 nearly or quite as great as the breadth of the segments, and which stand out at an angle 

 of 45 to 50 . 



Gaster oblong, about as long as but narrower than the thorax, subobtuse apically, with a 

 ventral plica. 



The female of caledonicum sp. n. is distinguished from those of antennatum 

 (Walker) and sabbas (Walker) primarily by the characters given in the key ; also 

 the propodeum of caledonicum slopes rather less steeply than in those species. 



I am unable at present to distinguish the male of caledonicum from those of 

 antennatum and sabbas.
