with in the present paper, by its relatively long marginal vein combined with the 

 long gaster of the female. 



Holotype $. England : Berkshire, Wytham Wood, 30.ix.1951 {Graham), in 

 Hope Department, University Museum, Oxford. 



Paratypes. Same locality as holotype, 2 $, 23.viii.1951, 1 <$, 20.ix.1951, 1 $, 

 5.ix.i959 {Graham) ; most of these specimens were swept in a damp meadow 

 between Wytham Wood and the River Thames. Ireland : Co. Dublin, Golliers- 

 town, 2 $, i.ix.1954 (Stelfox), in Graham collection. 



Biology. Unknown. 



Pteromalus smaragdus sp. n. 



(Text-fig. 391) 



9. Differs from that of procerus sp. n. as follows: 



Size larger (2-6 to 2-8 mm.). Antennal scape entirely or almost entirely testaceous ; fiagel- 

 lum conspicuously testaceous beneath. 



Head in dorsal view with temples longer (half or slightly more than half as long as the eyes). 

 POL 1-15 to 1-2 OOL. Antennae (Text-fig. 391) : flagellum only very slightly clavate ; 

 proximal segments of funicle relatively longer, the first segment as long as the pedicellus and 

 1-4 to 1-5 times as long as broad. Propodeum medially more obviously produced beyond the 

 bases of the hind coxae ; median area only 1-25 to 1-35 times as broad as long ; nucha larger, 

 occupying more than one third, though not quite half, the median length of the propodeum. 



Gaster ovate, longer than the thorax but shorter than head plus thorax, 1-55 to i-6 times as 

 long as broad, as broad as or slightly broader than the thorax ; basal tergite occupying about 

 one third the total length ; last tergite slightly shorter than its basal breadth. 



In the two specimens described, the postmarginal vein is slightly longer than the marginal 

 vein. 



From P. puparum, bifoveolatus , squamifer , venustus and planiscuta, this species differs particu- 

 larly in its longer marginal vein (see key to females). 



Holotype $. Sweden : Skane, Falsterbo, 10.viii.1951, swept from sand-dune 

 vegetation {Graham), in Graham collection. 



Paratype $. Same locality and habitat, 1 $, 27.vii.1959 {Graham), in Graham 

 collection.
