758 M. W. R. de V. GRAHAM 



Paratypes. Italy: S. Giorgio di Nogaro, i $ ; Lombardy, unlocalized, i <$, from 

 the same host as the holotype. Jugoslavia : Zagreb, 2 $, reared 17. v. 1929 from 

 M. [P.] senilis on Pyrausta nubilalis Hb. (B. Hergula), in BM(NH). 



This species falls into the species-group of submarginatus (Thomson), which it 

 resembles in many ways. It differs particularly in the characteristic features of the 

 head, especially in having the edges of the oral fossa, on either side of the clypeus, 

 distinctly curved and projecting below the front margin of the clypeus, in 

 submarginatus they are hardly curved and do not project ; the temples in dorsal view 

 also appear rather longer, and the scrobes are rather less deeply excavated (compare 

 Text-figs. 618 and 621). The thorax of submarginatus is not flattened, the 

 mesoscutum and scutellum being more convex than in genalis ; its propodeum is 

 slightly shorter and has the plicae rather less sharp and not so distinctly bisinuate. 



Eupteromalus potatoriae sp. n. 



(Text-figs. 622, 643) 



$. Body olive-green ; disc of gaster bronze. Antennae testaceous ; pedicellus and 

 flagellum more or less brown dorsally. Coxae concolorous with the thorax ; legs otherwise 

 testaceous, with the tips of the tarsi brown. Tegulae testaceous. Wings hyaline ; veins 

 testaceous. Length 1-5-1-7 mm. 



Head in dorsal view (Text-fig. 622) about twice as broad as long ; temples slightly more than 

 one third as long as eyes, converging fairly strongly, somewhat rounded posteriorly ; ocelli 

 very small, separated by rather more than three times their major diameter from the eyes ; 

 POL 1-15-1-25 OOL. Head in front view subtrapeziform, about 1-3 times as broad as high. 

 Genae somewhat buccate, malar space nearly half length of eye. Eyes about 1-4 times as long 

 as broad, separated by about 1-4 times their length. Mandibles rather small, both with 4 teeth. 

 Clypeus strigose, its anterior margin hardly produced and very shallowly emarginate medially. 

 Head otherwise finely reticulate. Antennae (Text-fig. 634) inserted distinctly above level of 

 ventral edge of eyes ; combined length of pedicellus and flagellum slightly less than breadth of 

 head; scape a little shorter than an eye, reaching nearly to the level of the vertex ; pedicellus 

 nearly twice as long as broad, distinctly longer than anelli plus first funicular segment ; flagellum 

 fairly stout, subclavate, proximally slightly stouter than the pedicellus ; funicular segments all 

 very slightly transverse, the first sometimes very slightly shorter than the second segment ; 

 clava about as long as the three preceding funicular segments together ; sensilla of funicle 

 fairly numerous. 



Thorax about i-6 times as long as broad. Pronotal collar weakly irregularly margined, 

 reticulate with a smooth strip along its hind edge. Mesoscutum about twice as broad as long, 

 finely reticulate ; notauli moderately deep. Scutellum about as long as mesoscutum, slightly 

 broader than long, convex, finely reticulate (especially posteriorly). Propodeum medially fully 

 three quarters as long as scutellum ; median area 1-1-1-2 times as broad as long, finely reticu- 

 late ; nucha more coarsely reticulate, occupying somewhat less than half the length of the pro- 

 podeum ; median carina fairly strong, reaching to the base or to the middle of the nucha ; 

 plicae complete but sharp only posteriorly ; callus rather thinly pilose with only 1-2 hairs 

 above the supracoxal flange. Fore wing about 2-3 times as long as broad ; basal cell and 

 basal vein bare ; speculum open below ; marginal vein 1-65-1-75 times as long as the 

 stigmal vein ; postmarginal vein distinctly shorter than the marginal. 



Gaster ovate, about as long as the thorax and about 1-5 times as long as broad, acute apically ; 

 basal tergite occupying slightly more than one third the total length ; last tergite slightly 

 shorter than its basal breadth ; tips of ovipositor sheaths just visible.
