42 (41) Anterior margin of clypeus with three asymmetric teeth (Text-fig. 44) 



MISCOGASTERINAE (part) (p. 95) 



- Anterior margin of clypeus either edentate, or if with teeth or lobes, then these 



are not asymmetric .......... 43 



43 (42) Petiole of gaster conspicuous, sculptured, reticulate or strigose, usually more 



or less elongate, rarely transverse ....... 44 



- Petiole of gaster smooth or nearly so, usually more or less transverse and 



relatively inconspicuous, rarely somewhat longer than broad ... 45 



44 (43) Anterior margin of clypeus bi- or tridentate MISCOGASTERINAE (part) (p. 95) 



- Anterior margin of clypeus without teeth. PTEROMALINAE (part) (p. 352) 



45 (43) Anterior margin of clypeus (cf. Text-figs. 170, 685) with two slightly pro- 



jecting sharp teeth .......... 46 



- Anterior margin of clypeus not of this form ; often more or less emarginate 



(Text-figs. 346, 394, 496, 510, 514, 526, 529, 566, 655, 658-660) or incised 

 (Text-figs. 361, 393, 528, 654) but then the angles on either side of the 

 emargination are blunt . . PTEROMALINAE (most species) (p. 352) 



46 (45) Antennae inserted low on the head, not or hardly above the level of the ventral 



edge of the eyes ; axillae meeting or nearly meeting, so that the scutellum 

 touches the mesoscutum only on a narrow base or at a point (as in Text-figs. 

 130, 141, 143, 169) ; clypeus reticulate or smooth 



MISCOGASTERINAE (part) (p. 95) 



- Antennae inserted higher, distinctly above the level of the ventral edge of the 



eyes ; axillae (cf. Text-figs. 316, 317, 511) widely separated, so that the 

 scutellum touches the mesoscutum on a broad base ; clypeus most often 

 striate PTEROMALINAE (part) (p. 352) 



47 (33) Antennae with three anelli and five funicular segments (Nikolskayana only) 



PTEROMALINAE (part) (p. 352) 



- Antennae with one anellus, or without anelli ; with seven or eight funicular 



segments ............ 48 



48 (47) Head (Text-fig. 47) massive, in female much, in male somewhat, broader than 



thorax ; clypeus with strong radiating striae which extend some distance 

 up the face and genae ; inner orbits of eyes virtually parallel. Head and 

 thorax without conspicuous piliferous punctures. Antennal formula 

 1 1083 (anelli not clearly differentiated) . . . CRATOMINAE (p. 848) 



- Head less massive, not much broader than thorax ; clypeus without strong 



radiating striae (nearly always reticulate without any striae) ; inner orbits 

 of eyes usually diverging ventrad, sometimes strongly so. Head and thorax 

 sometimes with conspicuous piliferous punctures ; antennae often with an 

 anellus ............ 49 



49 (48) Males only. Either the pedicellus has a comb of outstanding hairs beneath 



(Text-fig. 42) ; or the coxae, gastral petiole, and base of gaster are all more 

 or less red, the propodeal spiracles are small, circular, and separated by 

 much more than their own diameter from the hind margin of the metanotum 



EUPELMIDAE (part) 



- Either females ; or males in which the antennal pedicellus lacks a comb of 



outstanding hairs beneath, the coxae petiole and base of gaster are not 

 simultaneously red, and the propodeal spiracles are not more than their own 

 diameter from the hind margin of the metanotum 



CLEONYMINAE (p. 35) 



50 (28) Antennae with two or more anelli . . . . . . . .51 



- Antennae with only one anellus (11 1 73) ....... 54 



51 (50) Either the hind femora beneath have a tooth, some teeth, or fine serrations ; 



or else the occiput is margined TORYMIDAE (part)
