40 THE ENTOMOLOGIST. 



by Walker. Ratzeburg mentions two or three others, in 

 addition to those noticed above. Next to the Chalcididae, 

 but lower in the scale of creation than that family, come the 

 Proctotrupidae, the most slightly-developed of all the Hyme- 

 noptera; of this family two or three species are connected 

 with oak-apples. Walker names two, — a Ceraphron and an 

 Inostemma (Platygasterida^); Ratzeburg ('Die Ichneumonen,' 

 iii. 181) figures a Ceraphron bred from these galls, and which 

 he erected into a new genus — Dendiocerus Lichtensteinii ; 

 this may be synonymous with the first species of Walker — 

 Ceraphronidae. 



Dipt ERA. 



Cecidomyia sp. ? — Of the two species of Cecidomyidse, 

 bred by Walker, it is very probable that one was the 

 C. inflexa, Bremi. Specimens of Tipulidte have occurred 

 to me as also to Mr. Rothera, in the summer of the first year, 

 from these galls ; but they belong rather to Sciara than 

 Cecidomyia, I think. 



Anthontyia pluvialis. — This is the typical species of the 

 restricted genus Anthomyia. A. (Homalomyia) canicu- 

 laris, L., is said to be associated with cabbages, but there 

 are many very closely-allied species. 



Lepidoptera. 



Toririx viridana, L. — Ratzeburg, in his ' Die Ichneu- 

 monen,' gives sixteen Hymenopterous parasites of this 

 species, viz, three Braconidse, ten Ichneumonidae, and three 

 Chalcididae ; of these Hcmiteles areator only is included 

 amongst Walker's insects. It is probable that two or three 

 pupae of this pretty, but far too common, little moth were 

 collected by Walker with the galls, and so came to be bred 

 accidentally with one of its parasites. 



Zeiraphera comviunana. — This is the Poedisca (Pcecilo- 

 chroma) corlicana, Hilb., which species is a frequent feeder 

 on these galls : but there is another Hiibnerian P. corticana 

 amongst the Tortrices, with which it must not be confounded 

 — the Antithesia (Penthina) corticana (= picana, FroL), 

 which feeds on the leaf-buds of willow. 



Chcstochilus sylvellus. — This species is Cerostoma syl- 

 vella, L.
