PTEROMALIDAE OF N.W. EUROPE 385 



exserted, the exserted part about half as long as hind tibia ; or the 

 antennae are inserted well below the ventral edge of the eyes and very 

 close to the clypeus. Basal cell of fore wing more or less extensively pilose 



distally ANOGMUS Forster (p. 628) 



Thorax nearly always distinctly arched dorsally, with the upper surface of 

 the scutellum appearing distinctly curved in profile ; if the thorax is rather 

 distinctly flattened, then the scutellum is slightly longer than broad and the 

 third anellus is subquadrate. Mesopleuron rarely entirely reticulate, 

 usually with a partly to wholly smooth area below the base of the hind 

 wing. Ovipositor sheaths never so far exserted. Antennae usually 

 inserted level with or slightly above the ventral edge of the eyes, rarely 

 slightly below ........... 191 



191 (190) Plicae of propodeum usually absent or indicated only in the hinder half of 



the sclerite, occasionally traceable farther forward, but then extremely 

 weak ; antennae inserted distinctly above level of ventral edge of eyes, 

 their toruli nearly equidistant from the median ocellus and the anterior 

 margin of the clypeus ; clypeus reticulate or at most partly striate. 

 Postmarginal vein of fore wing usually as long as or longer than the mar- 

 ginal vein, rarely slightly shorter. Both mandibles with three teeth . 192 

 Plicae of propodeum usually complete, if vague anteriorly or incomplete then 

 the antennae are inserted at or hardly above the level of the ventral edge 

 of the eyes, and at least slightly nearer to the anterior margin of the 

 clypeus than to the median ocellus, whilst the clypeus is sometimes wholly 

 striate. Right mandible, rarely also left mandible, with four teeth. . 193 



192 (191) Pronotal collar finely though sharply margined anteriorly. Propodeum 



(medially) slightly more than half as long as the scutellum ; surface be- 

 tween the spiracles finely reticulate, not very shiny ; plicae often indicated 

 posteriorly and sometimes traceable well forward 



CRICELLIUS Thomson (p. 591) 

 - Pronotal collar rounded off anteriorly into the neck. Propodeum (medially) 



hardly one third as long as the scutellum ; surface between the spiracles 

 shiny, weakly alutaceous to virtually smooth ; plicae absent

 POL 1-3 to i-6 times OOL 194 



194 (193) Left mandible with three teeth, right mandible with four. Mesoscutum 



without, or with hardly perceptible piliferous punctures. Propodeal 

 spiracles large, oval. Pronotal collar reticulate. Antenna with third 

 anellus quadrate or only slightly transverse MESOPOLOBUS Westwood (p. 638) 

 Both mandibles with four teeth. Mesoscutum with numerous fairly distinct 

 piliferous punctures. Propodeal spiracles small, subcircular. Pronotal 

 collar with a more or less shiny strip along its hind edge. Antenna with 

 third anellus about three times as broad as long MERAPORUS Walker (p. 681) 



195 (60) Hind margin of basal segment of gaster not trilobed. Basal cell of fore wing 



bare, speculum large ..... NORBANUS Walker (p. 437) 



Hind margin of basal segment of gaster (Text-fig. 320) trilobed. Basal cell of 

 fore wing mainly to entirely pilose, speculum absent or rudimentary 



PICROSCYTOIDES Masi (p. 441) 



196 (177) Fore wing with speculum absent or rudimentary ; basal cell mainly to en- 



tirely pilose ; hind margin of basal tergite of gaster (Text-fig. 321) pro- 

 duced and emarginate medially ; antennae inserted at or hardly above 

 level of ventral edge of eyes . . STENOSELMA Delucchi (p. 437)
