PTEROMALIDAE OF N.W. EUROPE 755 



converge strongly towards the nucha ; in fucicola the plicae curve outwards from 

 the base and then sweep inwards towards the nucha in a regular arc. Finally, in 

 albopilosus the hairs clothing the surface of the wing beyond the speculum are 

 rather denser than in fucicola. In female fucicola the wings are sometimes reduced 

 in size, but all my specimens of albopilosus are macropterous. 



Holotype $. Sweden : Skane, Falsterbo, 8.viii.io,59 (Graham) in Graham 

 collection. 



Paratypes. Same locality as holotype, 1 £, 8 $, 8.viii.io.59 (Graham), in Graham

 foliage of Salix cinerea L. 



Biology. Unknown. 



Eupteromalus littoralis sp. n. 



(Text-figs. 633, 644) 



$. Body with greenish and brassy or bronze reflections. Mandibles reddish with darker 

 teeth. Antennae blackish, the proximal part of the scape more or less extensively reddish. 

 Coxae concolorous with the thorax, legs otherwise mainly rust-red ; sometimes the knees, 

 apices of the tibiae, and bases of the tarsi are paler than the rest, on the other hand in darker 

 specimens the femora, less often the tibiae and the tips of the tarsi, may be infuscated. Tegulae 

 testaceous to fuscous ; wings sometimes hyaline, but more often the fore wing is yellowish- 

 tinged and sometimes it is clouded with brownish . Length 1 -7-2-6 mm. 



Resembles the female of fucicola (Walker), from which it differs in the characters mentioned 

 in the key. It also resembles albopilosus, but differs as follows : 



Malar space slightly longer, about three fifths the length of an eye. Left mandible with 3, 

 right mandible with 4, teeth. Antennal scape slightly longer than an eye and reaching the level 

 of the vertex ; pedicellus slightly longer ; POL 1-2-1-27 OOL. 



Hairs on the propodeal callus much less dense, hardly concealing the surface beneath, not 

 covering the spiracular sulci and not extending so close to the nucha ; plicae arcuate right from 

 the base as in fucicola ; nucha larger, occupying fully half the length of the propodeum ; 

 basal tergite of gaster with few hairs at the sides. 



The marginal vein of the fore wing is 1-3-1-4 times as long as the stigmal vein. 



The distal funicular segments (Text-fig. 633) tend to be slightly shorter and broader than in 

 albopilosus, the fourth sometimes being very slightly transverse and 5 and 6 distinctly so. 



o*. Colour as in female, but femora and tibiae not infuscate. Length 1-6-2 mm. Head of 

 characteristic shape (Text-fig. 644 and couplet 7 of key to o\J). Antenna with first anellus 

 somewhat transverse, second quadrate or very slightly transverse ; funicle proximally not 

 stouter than the pedicellus in profile ; first funicular segment half to two thirds as long as the 

 pedicellus, about 1-5 times as long as broad, second similar, rest decreasing gradually in length, 

 fifth quadrate, sixth quadrate or very slightly transverse ; clava about as long as z\ funicular 

 segments ; hairs of flagellum standing out slightly. Gaster slightly longer than broad, shorter 

 than but a little broader than the thorax ; basal tergite occupying about half the total length.

 swept from marsh vegetation (Graham), in Hope Department, University Museum,
