332 Mr. F. Walker on the species of ChalcidHes 



a little in advance : antenna? black, subclavate, not longer than the 

 thorax ; first joint long, slender, fulvous, black at the tip ; second 

 cyathiform ; third and fourth very minute ; fifth and following joints 

 to the tenth successively yet slightly shorter and broader ; club fusi- 

 form, more than twice the length of the tenth joint : thorax elliptical, 

 broader before than behind : prothorax transverse, very short, narrow 

 in front : scutum of the mesothorax broad ; sutures of the parapsides 

 very indistinct, so that the latter seem almost to form one segment 

 with the scutum ; axillae large, triangular, not conniving ; scutellum 

 rhomboidal, prominent, much more convex than the scutum, having 

 a very indistinct transverse suture near its hind border : metathorax 

 transverse, very short : propodeon large, obconic, declining : podeon 

 stout, very short : abdomen elliptical, shining, very minutely squa- 

 meous, almost smooth, narrow, but hardly longer than the thorax ; 

 metapodeon short, conical, decumbent in front, shorter than one- 

 fourth of the length of the abdomen ; octoon much less than half the 

 length of the metapodeon ; ennaton at least twice the length of the 

 octoon ; decaton a little longer than the ennaton ; protelum a little 

 longer than the decaton ; paratelum and telum very short : oviduct 

 concealed : legs fulvous ; coxae and thighs green ; middle and hind 

 tarsi yellow, their tips fuscous : wings of moderate size, very slightly 

 tinged with fuscous ; nervures piceous ; humerus much less than half 

 the length of the wing ; ulna short, thick, not more than one-third 

 of the length of the humerus ; radius twice the length of the ulna ; 

 cubitus longer than the ulna ; stigma small, emitting a very distinct 

 branch.

Zetterstedt in his f Insecta Lapponica ' describes the following 

 twenty-one species of Chalcidites as belonging to Pteromalus ; 

 many of them, as it will be observed, have been separated from 

 that genus. 



1. quadrum, Fair. (Cheiropachys) ; 2. hirtipes (Trigonoderus ?) ; 

 3. tarsatus; 4. curtus ; 5. puparum, Linn. ; 6. violaceus ; 7. petio- 

 latus (Asaphes vulgaris ?) ; 8. parvulus (Pteromalus Pyttalus ?) ; 

 9. gracilicornis ; 10. crassicornis ; 11. subvirescens (Pteromalus 

 Rhinthon ?) ; 12. albipennis (lera ?) ; 13. mandibularis ; 14. socius ; 

 15. tibiellus; 16. palpigerus (Pachylarthrus patellanus) ; 17. rotun- 

 diventris (Pteromalus domesticus ?) ; 18. apicalis ; 19. brevicornis ; 

 20. pubicornis (Cyrtogaster vulgaris ?) ; 21. petioliventris. 



Cyrtogaster vulgaris, Ent. Mag. i. 382. Alten.

Body narrow, green : head and thorax convex, finely squameous :
