posterior ocelli distinctly less than the distance between one of them and the eye- 

 margin ; ovipositor sheath about two thirds as long as the hind tibia. Fiji Is. 



daimenes sp. n. (p. ioo) 



49 Metacarp hardly twice as long as its distance from the apex of the radial cell. 



Costula of propodeum absent. Thailand . . . despectus sp. n. (p. 103) 



- Metacarp at least four times as long as its distance from the apex of the radial cell . 50 



50 Vertex behind the ocelli, and the temples, closely sculptured and dull, the surface 



sharply contrasting with the polished occiput ; mesoscutum dull, closely, 

 sharply punctate and, seen slightly from in front, appearing silvery owing to close, 

 dense pubescence ; metacarp about four times as long as its distance from the apex 

 of the radial cell. New Guinea ..... painei sp. n. (p. 101) 



- Vertex and temples more finely sculptured, shiny and not so sharply contrasting 



with the polished occiput ; mesoscutum much more shiny in spite of its punctation 

 and completely lacking this silvery-grey appearance ; metacarp between five and 

 six times longer than its distance from the apex of the radial cell . . . 51 



51 Legs, except coxae, virtually entirely yellow ; metacarp about five times as long as 



its distance from the apex of the radial cell ; ovipositor thick, with abrupt apical 

 attenuation (Text-fig. 83) ; hypopygium evenly sclerotised all over and without 

 lateral creases. Malaya ...... scultena sp. n. (p. 101) 



- Legs, in addition to the coxae, with at least the hind femur and apical half of the hind 



tibia deeply infuscate ; metacarp about six times as long as its distance from the 

 apex of the radial cell ; ovipositor less thick and with hardly a trace of such an 

 apical attenuation; hypopygium membranous at sides and here with longi- 

 tudinal creases. Fiji Is. ...... . aglaus sp. n. (p. 66) 



52 Stigma pallid with a darker border (yellowish in ater) ...... 53 



- Stigma evenly brown or at most with pale basal spot ...... 84 



53 Median field of tergite (2 + 3) long, subrectangular, about one and a half times as 



wide apically as long medially (Text-fig. 80). 



Temples very coarsely rugose-punctate ; ovipositor sheath about twice as long 

 as the hind tibia. Java ....... dictys sp. n. (p. 90) 



- Median field of tergite (2 + 3) never as long as this, at least about twice as wide as 



long but usually much more transverse ........ 54 



54 Disc of scutellum with strong punctation at least laterally ; sometimes almost 



rugose-striate along sides ; strongly narrowed behind and here almost conically 

 raised. 



Head coarsely rugose between the posterior ocellus and the eye-margin ; ovi- 

 positor sheath about as long as the hind tibia ; costula of the propodeum distinct 

 throughout ............ 55 



- Disc of scutellum rarely with as much rugosity as this and then either the costula of 



the propodeum is absent or ill defined, or the ovipositor sheath is still longer . . 56 



55 Hind femur and hind tibia entirely yellow ; cubitellan cell of the hind wing about as 



long as high ; hairs of the ovipositor sheath all very short and dense ; ovipositor 

 sheath very slightly longer than the hind tibia. Malaya . . lanassa sp. n. (p. 86) 



- Hind femur entirely, and the hind tibia at apex, infuscate ; cubitellan cell of the hind 



wing obviously higher than long ; hairs of the ovipositor sheath longer and more 

 upstanding ; ovipositor sheath as long as the hind tibia. Malaya 



goron sp. n. (p. 89) 



56 Costula of the propodeum virtually absent ........ 57 



- Costula of the propodeum more or less distinctly defined or at least a distinct keel 



enclosing the spiracle behind . . . . . . . . .71 



57 Vertex immediately behind the ocelli with a wide, shallow furrow, which is faintly 



dull by reason of microscopic, transverse aciculation and which extends longitudin- 

 ally halfway down the occiput.
