rearing Arclia fiiligiiiosa, and llio results prove that species 

 to be (at least at Sontbsea) double-broDcled. Will those of 

 your readers who have bred ihe insect let us know in what 

 parts of Great Britain it is single-brooded ? On the 30th of 

 last May I received, from a lady at Leominster, a few eggs of 

 this species which bad been deposited in a chip-box. On 

 the 5th of June the larvae emerged, fed up with surprising 

 rajfidity, and entered the pupa state between the 1st and 5th 

 of July. The fiist imago appeared on the lOth, and the last 

 on the 13th, of that month. These deposited eggs on the 

 side of the breeding-cage, which hatched in ten days, and the 

 larvae are now about half- grown, and will be nearly full-fed 

 by the time they hybernate, if they do not go to pnpaj this 

 autumn. I am positive that these results were not brought 

 about by forcing, as the larva? were kept in a cage out-of- 

 doors, and supplied with fresh dock-leaves twice a week. I 

 send you a i'ew of the larvae of the second brood, that you 

 may have the opportunity of following them through their 

 future changes, and of corroborating what I have written. —

Names of Galls. — Will 30U oblige me with the names of 

 the insects which cause tlje accompanying galls ? — W. Thom- 

 son ; Forest Hill, September 25, 1866. 



[The larger is the artichoke gall : it appears to be an 

 abnormal development of the acorn cup, and is peculiarly 

 interesting as a uiimetic representation of the acorn cup of a 

 species of oak which does not occur in Britain : the insect 

 which causes it is Cynips Fecundatrix of Hartig. Mr. Walker 

 has found the following insects to be parasitic on the arti- 

 choke gall: — Entedon leptoneurus and Megastigmus Bohe- 

 manni. The sn)all flat gall is commonly known as the oak 

 spangle ; for many years it was a matter of doubt whether it 

 was a gall or a fungus, both Botanists and Entomologists 

 being desirous of rejecting it. It has, however, been ascer- 

 tained that it is produced by a minute gall-fly, called Cynips 

 longipennis. I shall at all times be gratified to receive 

 questions about galls or gall-flies, and have no doubt of 

 being able to answer them, with the kind and ever ready 

 assistance of Mr. Walker. — Edward Newman.] 



E(jif Parasite of Oryyia anliqua, ^i^c. — Mr. Hammond, of 

 St. Alban's Court, has sent me some eggs of Orgyia antiqua
