PTEROMALIDAE OF N.W. EUROPE 29 



scentic, smooth or transversely-aciculate strip ; or with a convex, 

 reticulate nucha. The propodeum, medially, is often produced caudad of 

 the bases of the hind coxae ; the supracoxal flanges, except in a few 

 species, are not very narrow and linear. Anterior margin of clypeus often 

 with teeth. Postmarginal vein of fore wing often longer than the marginal 

 vein. Petiole of gaster often distinctly sculptured, sometimes longer than 

 broad ............ 17 



- Antennae 10-, 11-, or 12-segmented ; if with two anelli, then only five funicular 



segments ; sometimes three or four anelli but in that case at most three 

 funicular segments ; often only one anellus but then at most six funicular 

 segments. 



Propodeum without a nucha, its petiolar foramen bounded by a simple 

 ridge ; propodeum, medially, not or hardly produced caudad of the bases of 

 the hind coxae ; supracoxal flanges, except in a few species, very narrow 

 and linear. Anterior margin of clypeus rarely with teeth. Postmarginal vein 

 of fore wing in most species shorter than, and only rarely longer than, 

 the marginal vein. Petiole of gaster smooth, usually more or less transverse, 

 rarely as long as broad. Body of Semiotellus $, Text-fig. 56 ; of Pirene 

 $, Text-fig. 57 MISCOGASTERINAE (part) (p. 95) 



17 (16) Antennae inserted very high on the head, their toruli distinctly nearer to the 



median ocellus than to the anterior margin of the clypeus . . . 18 



- Antennae inserted lower down the head, their toruli equidistant from the 



median ocellus and the anterior margin of the clypeus, or nearer to the 

 latter ............ 19 



18 (17) Antennal formula 11263 ; marginal vein of fore wing 4 to 4-5 times as long 



as the stigmal vein, costal cell very narrow, 12 to 20 times as long as its 

 maximum breadth ; all coxae, femora, and tibiae red, sometimes also the 

 gastral petiole and part of the gaster. Body of Panstenon $, Text-fig. 55 



PANSTENONINAE (p. 92) 



- Either the antennal formula is 1 1 1 73 ; or else the marginal vein of the fore wing 



is less than three times as long as the stigmal vein, the costal cell is relatively 

 broader, and at least the coxae are mainly metallic . . . . . 19 



19 (18) Marginal vein of fore wing 3-5 to 6 times as long as the stigmal vein ; pro- 



notal collar (Text-fig. 53) large, at least half as long as the mesoscutum, 

 sharply margined anteriorly. Antennal formula 11 263 or 11173 ; hind 

 tibia with two strong apical spurs ; petiole of gaster usually distinctly 

 sculptured, longer than broad, and subrectangular (Text-fig. 53) 



CHRYSOLAMPINAE (p. 86) 



- Marginal vein of fore wing rarely more than three times as long as the stigmal 



vein; if more than three times, then either the pronotal collar is shorter, 



or else it is immarginate ......... 20 



20 (19) Body either brown to black and non-metallic ; or else the head and thorax 



at least partly yellow to reddish . . . . . . . .21 



Body at least slightly metallic ; head and thorax without yellow or reddish 



marldngs ............ 22 



21 (20) Pronotum short, in dorsal view with its sides converging strongly forwards 



(a few Ormocerini ; some exotic Brachyscelidiphagini) 



MISCOGASTERINAE (part) (p. 95) 

 Pronotum long, in dorsal view appearing subrectangular, or having its sides 



at most slightly convergent TORYMIDAE (part) 



22 (20) Genae with a sharp edge or border which extends well up the temples ; 



occiput also margined. Pronotum (Text-fig. 75) large and subrectangular.
