- Fore wing speculum distinct, often large ; basal cell usually mainly to en- 



tirely bare, if extensively pilose then the basal tergite of the gaster is not 

 produced as in the above. Antennae often inserted distinctly above level 

 of ventral edge of eyes . . . . . . . . .197 



197 (196) Fore wing with two fuscous clouds, one below the parastigma, the other 



below the stigmal vein. Propodeum with a convex reticulate nucha ; 

 mesopleuron with a smooth triangular area below the base of the hind- 

 wing ; anterior margin of clypeus incised medially. Antennae inserted 

 only very slightly above level of ventral edge of eyes 



DINARMOIDES Masi (p. 436) 



- Fore wing immaculate. Either the propodeal nucha is not developed ; or the 



triangular area of the mesopleuron is at least mainly reticulate ; or the 

 anterior margin of the clypeus is not incised . . . . . .198 



198 (197) Propodeum with a subglobose reticulate nucha which projects beyond the 



bases of the hind coxae ; mesopleuron wholly reticulate, or with the 

 triangular area below the base of the hind wing at most partly smooth . 199 



- Propodeum usually without a subglobose nucha ; if with one then it does not 



project beyond the bases of the hind coxae, whilst the triangular area of the 

 mesopleuron, below the base of the hind wing, is entirely smooth . . 200 



199 (198) Anterior margin of clypeus bidentate ; marginal vein of fore wing slightly 



shorter than the stigmal vein, stigma rather large OEDAULE Waterston (p. 435) 



- Anterior margin of clypeus shallowly emarginate ; marginal vein of fore 



wing at least slightly longer than the stigmal vein, stigma small 



DINARMUS Thomson (p. 434) 



200 (198) Antennae inserted only very slightly above the level of the ventral edge of the 



eyes ; propodeum with a convex, weakly sculptured and shiny nucha 



ANISOPTEROMALUS Ruschka (p. 433) 



- Antennae inserted well above level of ventral edge of eyes ; propodeal nucha 



not developed but represented merely by a narrow transverse strip . . 201 



201 (200) Antennal toruli situated much nearer to the median ocellus than to the 



anterior margin of the clypeus ; funicular segments very long, the first 

 about four times, fifth about twice, as long as broad. Malar space from 

 two thirds to nearly three quarters the length of an eye, the latter relatively 

 small. Anterior margin of clypeus virtually truncate 



GUGOLZIA Delucchi (p. 430) 

 Antennal toruli situated about midway between the median ocellus and the 

 anterior margin of the clypeus, or only slightly above this level ; funicular 

 segments relatively less elongate. Malar space relatively shorter, eyes 

 larger. Anterior margin of clypeus at least slightly emarginate . . 202 



202 (201) Marginal vein of fore wing thickened at the base ; third anellus quadrate 



ISCHYROPTYX Delucchi (p. 433) 



- Marginal vein not thickened basally ; third anellus transverse . . . 203 



203 (202) Pronotal collar finely though fairly sharply margined throughout. Antennal 



clava in the type-species with its sutures oblique, and with a line of micro- 

 pilosity extending fully half way to the base. Genae, at least near the 

 mandibles, with a rather sharp edge . . OXYSYCHUS Delucchi (p. 432) 



- Pronotal collar not margined, or with at most a weak carina in the middle. 



Antennal clava with sutures not oblique, and with only a small area of 

 micropilosity on its third segment. Genae without a sharp edge 



CYRTOPTYX Delucchi (p. 430) 



204 (91) Anterior margin of clypeus with two rounded lobes between which is an 



incision. Pronotal collar virtually as wide as the mesoscutum ; thorax in 

 dorsal view squat, only slightly longer than broad. Postspiracular sclerite
