PTEROMALIDAE OF N.W. EUROPE 409 



ing nearly flat. Fore wing with at least the distal quarter of the basal cell 

 pilose . . . . . . . . . . . .171 



Thorax arched dorsally, the scutellum in profile appearing distinctly convex. 



Basal cell of fore wing usually bare or nearly so . . . .172 



171 (170) Either the antennae are inserted below the level of the ventral edge of the 



eyes ; or the mesepisternum is wholly reticulate and dull, and the genae are 

 prominent just above the bases of the mandibles (frontal view) 



ANOGMUS Forster (p. 628) 



- Lower edge of antennal toruli at or slightly above the level of the ventral 



edge of the eyes ; genae not prominent above bases of mandibles, but 

 evenly curved ; mesepisternum with the subtriangular area below base 

 of hind wing as a rule partly smooth MESOPOLOBUS Westwood (p. 638) 



172 (170) Antennal flagellum fuscous, subfiliform, with relatively long, moderately to 



strongly outstanding hairs ; lower edge of antennal toruli well above ventral 

 edge of eyes. Legs testaceous with at least the femora more or less in- 

 fuscate, sometimes also the tibiae. Both mandibles with three teeth 



CRICELLIUS Thomson (p. 591) 



— Antennal flagellum partly to entirely yellow or testaceous, clavate, with 



short at most slightly outstanding hairs ; lower edge of toruli sometimes 

 not or hardly above ventral edge of eyes. Femora and tibiae most often 

 entirely bright yellow, sometimes with the femora, occasionally also the 

 tibiae more or less, infuscate. Right mandible, or both mandibles, with 

 four teeth. . . . . . . . . . . .173 



173 (172) Propodeum with plicae usually complete, occasionally indicated at hind 



margin only. Second tergite of gaster not, or only slightly, shorter than 

 the third. Left mandible with three teeth, right mandible with four. 

 Antennal clava often obtuse . . MESOPOLOBUS Westwood (p. 638) 



Propodeum with plicae represented only by basal foveae. Second tergite 

 of gaster distinctly shorter than the third. Both mandibles with four 

 teeth. Antennal clava pointed at apex HOMOPORUS Thomson (p. 444)

Key to European Species 



(Females) 



1 Anterior margin of clypeus slightly produced but without teeth. Fore wing 



immaculate ; basal cell usually having a few hairs scattered over its distal 

 part, in addition to those on the basal vein ; stigma moderate-sized, tending 

 to be somewhat quadrangular, as long as or slightly longer than high . . 2
