 microsilgmn, Wlk. — This and the preceding species — C. 

 regius, Nees — are of general occurrence in oak-galls, as 

 probably might be inferred from the list of synonyms. 



Megastigmus dorsalis, Fabr. = Boliemanni, Ratz. = 

 xantliopygus, Forst. — This species has been bred from most 

 oak-galls. Dr. Mayr describes six varieties, and says: 

 "A. terminalis, a single specimen in July of the same 

 year, var. (/)." Mr. Walker seems to have had a succession 

 of emergences: it occurred with him from July of the first 

 year to June of the second. I have only bred it in June, 

 July, and August of the first year, and then commonly. It is 

 curious this species should not affect this gall so much in 

 Germany, as in Britain it is especially common in it ; e. g. 

 Walker's 1560 specimens compared to Mayr's 1, with his 

 numerous correspondents : it is also unnoticed by Ratzeburg 

 in connection with this gall. 



Eupelmidce. 



Eupehnus iirozonus, Dalm. — This species is figured in the 

 'Entomologist,' vi. 2-26, from one of A. H. Haliday's draw- 

 ings. It may be bred commonly from these galls in the 

 summer. Ratzeburg says of E. azureus, a synonym of this 

 species, that it is hyper-parasitic in this and other galls on 

 Eurytoraa and Microgaster. 



Pteromalidce. 



In addition to the fourteen species mentioned by Walker, 

 Ratzeburg gives the following, besides several doubtful 

 instances; but owing to the immense number of species, 

 and to the very close resemblance between many, the question 

 of synonymy must be difficult; but as with the Torymidae, 

 so with the Pteromalidae, several varieties and species are 

 recorded under different names; but in this genus we have 

 no Mayr to follow at present.
