768 M. W. R. de V. GRAHAM 



Type material. Lectotype male designated by Graham (19566). 



The males in a series of Eupteromalus from Holland in BM(NH) agree very well 

 with the lectotype of tigasis ; I believe all these specimens to be conspecific and the 

 following redescription is drawn from them. 



$. Extremely close to that of micropterus (Lindeman) but has the head in dorsal view 

 (Text-fig. 617) slightly less transverse, 2 08-2-15 times as broad as long ; the femora in three of 

 the specimens seen are mainly brownish or fuscous, and the tibiae are sometimes infuscate 

 medially. The host of micropterus is a Dipteron, that of tigasis a Lepidopteron. E. tigasis 

 differs from peregrinus sp. n. in having the antennal scape slightly longer, 0-9-0-96 the length of 

 an eye, reaching the vertex or even slightly above it ; median area of propodeum slightly more 

 transverse, 1-35-1-45 times as broad as long ; postmarginal vein not longer than the marginal, 

 the latter 1-5-1-6 times as long as the stigmal vein. 



o*. Differs from that of micropterus in being macropterous, and in its host. It differs from 

 that of peregrinus sp. n. in having the antennal scape slightly longer, the combined length of 

 pedicellus and flagellum fully equal to the breadth of the head ; postmarginal vein not longer 

 than the marginal. 



England : Isle of Wight (Lectotype^, coll. Walker). Holland : Wieringermeer, 

 3 <$, 1 $, 25.viii.1937, 1 <3\ 3 $, 10. ix. 1937, all reared from Bucculatrix maritima 

 Stainton (D. C. Geisjkes) ; specimens in BM(NH). Walker's original material was 

 captured in September, in the Isle of Wight, where the host cited above is known 

 to occur. 



Eupteromalus caricicola sp. n. 



(Text-figs. 614, 635) 



$. Head and thorax olive-green, here and there verging towards brassy and bluish ; gaster 

 with reflections of similar tints, particularly at the base and apex. Mandibles reddish with 

 darker teeth. Antennae fuscous ; the proximal half or rather more of the scape reddish ; 

 pedicellus slightly reddish beneath and at its apex ; clava slightly reddish beneath. Coxae 

 concolorous with the thorax, except their tips and the internal aspect of the fore coxa, which 

 are bright testaceous ; remainder of the legs bright or reddish testaceous, the knees, tips of the 

 mid and hind tibiae, and the bases of the mid and hind tarsi, paler. Tegulae mainly testaceous ; 

 wings hyaline or faintly yellowish, venation pale testaceous. Length 1-9-2-2 mm. 



Head in dorsal view (Text-fig. 614) slightly more than twice as broad as long ; temples about 

 one quarter as long as the eyes ; POL 1-3-1-4 OOL. In front view the head forms a regular 

 oval, the genae being moderately buccate, and is broader than high, ratio about 1-25 : 1. 

 Eyes rather large, separated by about 1-3 times their own length ; malar space slightly less 

 than half the length of an eye. Mandibles moderate-sized, both with 4 teeth. Antennae 

 (Text-fig. 635) inserted slightly nearer to the anterior margin of the clypeus than to the median 

 ocellus, but distinctly above the ventral edge of the eyes ; scape slightly shorter than an eye, 

 but reaching to or distinctly above the level of the vertex ; combined length of pedicellus and 

 flagellum equal to the breadth of the head ; pedicellus twice as long as broad, as long as anelli 

 plus first funicular segment ; flagellum only moderately clavate ; funicle proximally not 

 stouter than the pedicellus, its segments very slightly longer than broad, except the fifth and 

 sixth which are quadrate, or the sixth very slightly transverse ; clava about 2-5 times as long 

 as broad, slightly shorter than the combined length of the three preceding funicular segments ; 

 sensilla of funicle not very numerous. 



Thorax about i-6 times as long as broad. Pronotal collar margined throughout, the margin
