PTEROMALIDAE OF N.W. EUROPE 769 



sharp, especially medially ; behind this margin the surface is relatively smooth and shiny, 

 except at the sides. Mesoscutum about twice as broad as long, convex, finely reticulate, more 

 coarsely in the middle posteriorly. Scutellum fully as long as the mesoscutum. Propodeum 

 medially about three quarters as long as the scutellum ; its median area slightly broader than 

 long, moderately finely reticulate, the nucha rather more coarsely ; nucha occupying slightly 

 less than half the length of the propodeum ; median carina distinct ; plicae sharp ; callus 

 moderately thickly haired. Fore wing about 2-4 times as long as broad, far surpassing the tip 

 of the gaster ; basal cell, basal vein, and proximal portion of cubital vein, bare, basal cell and 

 speculum open below ; marginal vein about 1-5-1-6 times as long as the stigmal vein ; post- 

 marginal vein subequal in length to the marginal 



Gaster ovate, about as long and as broad as the thorax, about i-6 times as long as broad ; 

 acute but not acuminate apically ; basal tergite occupying rather less than half the total 

 length, its sides with a few hairs only ; last tergite distinctly shorter than its basal breadth ; 

 ovipositor sheaths projecting very slightly. 



o*. Differs from the $ as follows : 



Antennal scape reddish, darker at the apex ; pedicellus sometimes more extensively pale ; 

 mid coxa more or less reddish. Eyes larger, separated by about 12 times their length. Malar 

 space half or virtually half the length of an eye. Antenna with combined length of pedicellus 

 and flagellum slightly greater than the breadth of the head ; scape almost as long as an eye ; 

 flagellum more slender, only very slightly clavate ; funicular segments slightly longer than 

 broad, except the sixth which is quadrate ; flagellum clothed with hairs which stand out at an 

 angle of about 30 , the length of these hairs slightly less than the breadth of the segments that 

 bear them. Marginal vein 1-5-1-65 times as long as the stigmal vein. Gaster almost circular, 

 flattened, distinctly shorter than the thorax, but slightly broader ; basal tergite occupying 

 half the total length, the following tergite (second) about half as long as the basal tergite, 

 remaining tergites retracted and very strongly transverse. 



The female is very near that of maurus sp. n., but has the funicular segments of 

 the antenna relatively longer, the first segment not shorter than the second ; malar 

 space a little shorter ; size greater ; flagellum rather more slender. In female 

 maurus the combined length of pedicellus and flagellum is usually slightly less than, 

 occasionally equal to, the breadth of the head. 



The female of caricicola differs from that of exiguus (Walker) in having 4 teeth 

 in both mandibles ; pronotal collar sharply margined ; malar space a little shorter ; 

 antennae differing in the same feature as those mentioned as distinguishing it from 

 maurus. Most females of exiguus are smaller than those of caricicola.
