bearing so close a resemblance to certain 

 Fuiio-i, that tlioy wore at one time supposed 

 to bi> parasitic vegetable growths. These 

 galls, which are commonly known as oak- 

 spamjh's, may be met with in abundance 

 during the winter on the fallen leaves in oak 

 woods : the flies are i)roduced in the spring ; 

 and the most abundant species in this 

 coimtry is the Neuroteris longipennis (fig. 

 19). The root of the oak is attacked by 

 several kinds, one of which, Biorhizn aptera, 

 the partheuogenetic form of Teras termi- 

 nalis, is destitute of wings; another de- 

 posits its eggs in the male catkins of the 

 same tree, producing a series of galls re- 

 sembling a small bunch of currants. 



It would be impossible for us here to 

 enimierate the different kinds of galls pro- 

 duced by these beautiful little insects even 

 upon our indigenous plants and trees, the 

 history of which in many cases is very im- 

 perfect, whilst we have scarcely any in- 

 formation with regard to exotic species. 

 The most important of all is the common 

 gall-nut, which is produced by the puncture 

 of the Cynips lincforia upon the shoots of 

 the Qucrcus infectoria, a species of oak 

 growing in the Levant. The celebrated 

 Dead-sea apples are also found upon this 

 oak ; they ai'e as large as a good-sized apple, 

 and of a spongy texture internally, con- 

 taining only a single larva of a species which 

 has been described by Westwood under 

 the name of Cynips insana. 



All the species of Cynipidce do not, how- 

 ever, produce galls. The species of Hartig's 

 genus Syneryus deposit theu" eggs in other 

 galls, upon the substance of which the 

 larvae, when hatched, feed parasitically, and 

 finally devour the original tenant. Besides 

 these species, which live partly upon vege- 

 table and partly upon animal food, there are 

 many others, forming several genera in 

 Hartig's classification, which live entirely 

 as parasites upon other insects, especially 

 Aphides and the larvae of Dipterous flies ; 

 thus justifying the otherwise anomalous 

 position of the Cyoiipidfe, as a phytophagous 

 family in the Entomophagous group of the 

 Hymenoptera. Amongst these we need 

 only mention the species of the genus Allo- 

 tria, "SVestw. (Xystus, Hartig), of which a 

 very abundant one is parasitic upon the rose- 

 Aphis, and those of the genera Anaeharis, 

 Figites, and Ihalia. The latter, of which one 

 species only is known in this country, is 

 remarkable from the structure of its abdo- 

 men, which is knife-shaped, and has the 



segments nearly equal in length ; Ihalia 

 cidteJlata (PI. .30. fig. 20) is one of the largest 

 British Cynipidas. 



Adler's admirable memoir, in whieh 

 many of the galls are figured, will allow of 

 the identification of most, if not all the 

 British kinds.
