Head in dorsal view (Text-fig. 645) with temples at most one third as long as 



eyes. Left mandible with 3 teeth, right mandible with 4 . . . 23 



22 (21) Antenna with first funicular segment subtransverse and distinctly shorter 



than the second. 



Head, Text-fig. 643 ...... potatoriae sp. n. (p. 758) 



Antenna with first funicular segment quadrate and as long as the second 



lasiocampae sp. n. (p. 759) 



23 (21) Antenna with first segment of funicle quadrate, not or hardly shorter than the 



second ........ tigasis (Walker) (p. 767) 



Antenna with first segment of funicle slightly to very distinctly transverse, 

 from very slightly to much shorter than the second, in small specimens 

 virtually anelliform. 



Head, Text-fig. 645 ...... exiguus (Walker) (p. 770) 



Eupteromalus pompilicola sp. n. 



(Text-figs. 594, 595, 597) 



$. Body with rather weak bluish and bronze reflections. Mandibles reddish with darker 

 teeth. Antennal scape and pedicellus bright testaceous, the latter often more or less infuscate 

 distally ; flagellum brown. Coxae concolorous with the thorax ; legs otherwise bright 

 testaceous, except the fifth segment of all the tarsi, which is more or less brownish. Tegulae 

 and wing-venation testaceous, wings hyaline. Ovipositor sheaths testaceous. Length 155- 

 i-8 mm. 



Head in dorsal view (Text-fig. 594) about twice as broad as its maximum length, temples 

 nearly half the length of the eyes ; POL slightly greater than OOL. In front view the head 

 forms a regular oval, the genae being buccate, and is slightly broader than high. Anterior 

 margin of clypeus very distinctly produced medially. Mandibles large, both with 4 teeth. 

 Antennae (Test-fig. 597) inserted nearer to the anterior margin of the clypeus than to the 

 median ocellus, but the lower edge of the toruli slightly above the ventral edge of the eyes ; 

 scape, not counting the radicula, slightly shorter than an eye and not nearly reaching the level 

 of the median ocellus ; combined length of pedicellus and flagellum distinctly less than the 

 breadth of the head ; pedicellus rather more than twice as long as broad, about as long as the 

 anelli plus the first two funicular segments ; flagellum distinctly clavate ; first funicular 

 segment slightly transverse, the following segments more distinctly so. 



Thorax about i-6 times as long as broad. Pronotal collar, except laterally, with a distinct, 

 though irregular and not sharp, margin, reticulate, with a narrow smooth strip along its hind 

 edge. Mesoscutum rather more than twice as broad as long, convex, finely reticulate except 

 in the middle posteriorly. Scutellum slightly longer than the mesoscutum, finely reticulate. 

 Propodeum sloping at a moderate angle relative to the plane of the mesoscutum and scutellum, 

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

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

 than one third the length of the propodeum ; plicae sharp, especially basally ; median carina 

 distinct but tending to be irregular ; callus rather sparsely haired. Fore wing with basal cell 

 with 8-13 hairs scattered over its distal half, upon the upper surface of the wing ; veins thin, 

 marginal vein about 1-5 times as long as the postmarginal, and about 1-7 times as long as the 

 stigmal vein. 



Gaster (Text-fig. 595) almost circular, much shorter than but slightly broader than the 

 thorax ; basal tergite (the third abdominal) occupying about two thirds of the whole gaster, 

 its lateral margins almost bare ; remaining tergites very strongly transverse ; ovipositor 

 sheaths projecting slightly.
