 Females 



i Metacarp hardly one and a half times longer than its distance from the apex of the 

 radial cell. 



Head subtriangular, seen from in front ; mouth parts showing some degree of 

 lengthening ; ovipositor sheath not longer than the hind tibia .... 2 



- Metacarp at least about twice as long as its distance from the apex of the radial cell 



and then the ovipositor sheath is much longer than the hind tibia ... 6 



2 Eyes strongly convergent below (Text-fig. 97) ; inner spur of the hind tibia fully half 



as long as the hind basitarsus ; disc of scutellum dull, strongly, closely punctate, 

 except medially, its rugose posterior tip almost interrupting the posterior polished 

 band of the scutellum ........ trabea sp. n. (p. 107) 



- Eyes not convergent below ; inner spur of the hind tibia distinctly less than half as 



long as the hind basitarsus ; disc of scutellum much less rugose .... 3 



3 Setae of the 1st cubital cell very sparse, about twelve in number. 



Stigma evenly brown ; antenna as long as, or almost as long as, the body . 4 



- Setae of the 1st cubital cell much more numerous than this. 



Ovipositor sheath almost as long as the hind tibia ..... 5 



4 Ovipositor sheath hardly two thirds as long as the hind tibia ; antenna very thin, 



with the preapical segment about one and a half times longer than wide 



rosaces sp. n. (p. 107) 



- Ovipositor sheath fully as long as the hind tibia ; antenna distinctly a little thickened 



distally ; preapical segment hardly one and one third times longer than wide 



avion sp. n. (p. 109) 



5 Edge of vannal lobe beyond its widest part imperceptibly convex ; propodeum very 



shiny, almost polished ; mesoscutum weakly shining and with a very feeble 

 sculpture but with a duller zone of rugosity at each posterior extremity of the 

 notaulic course ........ eriophyes sp. n. (p. 109) 



- Edge of vannal lobe beyond its widest part straight ; propodeum finely rugose, its 



V-shaped areola more in evidence ; mesoscutum dull, almost coarsely rugose and 



with no emphasis along the course of the notaulices . . . patens sp. n. (p. 110) 



6 Face subrostriform ; ovipositor sheath about one and a half times longer than the 



hind tibia ; antenna very thin, with segment 14 fully twice as long as wide. 

 Metacarp about twice as long as its distance from the apex of the radial cell ; 

 stigma evenly dark brown ...... camirus sp. n. (p. no) 



- If the face shows any tendency to be rostriform or subtriangular, then the ovipositor 



sheath is much shorter and the antenna is neither so long nor so thin ... 7 



7 Head from in front distinctly subtriangular ; mouth parts lengthened. 



Setae of the median and submedian cells very sparse and widely absent along the 

 medius side of the cells ; ovipositor sheath fully as long as the hind tibia . . 8 



- Head from in front not subtriangular ; mouth parts not lengthened . . . 13 



8 Spines of the outer side of the hind tibia short, blunt, fire-red, very numerous, not 



upstanding ; segments 12-17 °f the antenna not evenly cylindrical, being slightly 

 swollen at apex on one side. 



Antenna distinctly shorter than the body, with segment 17 about one and one 

 third times longer than wide . . .... nepe sp. n. (p. 113) 



- Spines of the outer side of the hind tibia neither so short nor so blunt, nor so 



numerous as this, being obviously pointed and upstanding ; segments 12-17 OI the 

 antenna evenly cylindrical even if very short ....... 9 



9 Eyes distinctly convergent below ; at least the 1st and 2nd abscissae of the dis-
