36 THE ENTOMOLOGIST. 



imrautatnr, Nees, has been bred from these galls by Dr. 

 Reinhard ; it was probably parasitic on a Curculio. 



Microgaster sp. ? — Both sexes of Microgaster (Apanteles) 

 brevivenlris, Rtzb., have been bred from the gall of this 

 species, in which they were probably parasitic on Orchestes 

 Quercus. 



Aphidiits sp. ? — This undetermined species of Aphidius 

 was probably parasitic on an Aphis. 



In addition to the above list of Ichneumonidae, Ratzeburg 

 received three other species from his numerous corre- 

 spondents, as follows : — 



Cryptus hortulanus, Grv. (IchneunionidfE). — " Herr Reissig 

 bred one female from Cynips terrainalis galls at the end of 

 May of the second year ; with it the very common Hemiteles 

 punctatus." (Ichn. d. Forst. ii. 124.) 



Microtypus Wesmaelii, Rtzb. (Braconidae). Ratzeburg 

 himself bred a solitary individual from an A. terminalis gall, 

 which he erected into a new genus, separated from Micro- 

 gaster; it was bred, with hundreds of Torymidae, at the end 

 of June (1847). 



Microdiis rujipes, Wesm. = Therophiltts rvjipes, Nees. 

 (Braconidae). — Several specimens bred by Herr Bouche from 

 these galls, in which it was parasitic on Hedya ocellana. 



Chalcidid^. 

 Eurytomidee. 



Decatoma immaculata. — Ratzeburg records Eurytoma 

 signata, Nees, as very commonly bred from this gall ; he 

 also gives it as parasitic in several other galls and on a 

 Lithocolletis. It is undoubtedly a compound species, and 

 from his description certainly a Decatoma; so the A. termi- 

 nalis-bred specimens were probably the same species as 

 Walker's D. immaculata. 



TorymidcB. 



Callimome nigricornis, Fab. — This is Syntomaspis caudata, 

 Nees. Ratzeburg gives Torymus admirabilis, Forst. (= cri- 

 nicaudis, Ratz.) as bred commonly from A. terminalis galls; 

 they are both synonyms of this species, which occurs very 

 abundantly in the spring of the second year. It has also
