822 REPORTS ON THE INSECT-HOUSE. [NoV. 15, 



obtained, some of which have hatched, and are kept in the studio in 

 a proper vessel for hibernation. An experiment is being tried with 

 some few of these larvae in order to force them to become imagos 

 before winter ; they are growing slowly at present. 



No. 23. Centra vinula. — A nice lot of small larvae of this species 

 was presented by Mrs. Blandford. A part of these placed at once in 

 this cage fed up quickly, and are now in cocoons, having spun up in 

 a piece of cork placed in the cage for them ; the other half are now 

 in the cage as larvae of different growths. 



No. 24. Cossus ligniperda. — Almost every day a larva of this 

 species has come out of the piece of willow exhibited in the cage ; 

 after crawhng about, it has reentered the branch. There are two 

 growths in the wood — those of last year's hatching and of the pre- 

 vious year. 



No. 25. Lasiocampa quercus. — Larvae of this species have been 

 exhibited, but at present no cocoons formed ; it is a difficult larva 

 to breed. 



No. 26. Orgyia antiqua. — A plentiful supply of the larvae of this 

 abundant species has been obtained from the gardens ; and when 

 a female has freshly emerged in this cage, it has attracted from the 

 outside a number of males. One morning the cage was quite beset 

 with those amorous little creatures, which refused to be driven away, 

 and could easily be picked up by the fingers ; at other times this is 

 not an easy species to capture. 



In the small cages at the end of the house, and on the tables, 



have been exhibited in succession such insects as appear at this season. 



Pupfe of Lithosia quadra were obtained from the New Forest, but 



a small percentage of imagos appeared, the majority being infested 



with Ichneumon flies. 



Liparis monacha, also received from the same locality in the same 

 condition. Larva) oi Biston hirtaria, Acronycta psi and A. megace- 

 phala, and other common species occurring about London, have been 

 gathered and exhibited ; also larvaj of the Ladybirds {Coccinellidoi), 

 Lacewing flies (Hemerobiid(e), the larvae of which are named Aphis- 

 lions, from feeding upon Aphides. 



Perfect specimens of the Ant-lions {Myrmeleon) commenced to 

 emerge this month, and some fine ones have been preserved. 



Selenia ilktstraria. — Some eggs of this pretty species were pre- 

 sented to the Society during the month by Miss Golding Bird, and 

 hatched the following day, the 20th instant. Apart of these are now 

 exhibited in a tube ; the others are retained for future exhibition. 



Heterogynis pcnnella. — These little larvae, presented by Lord Wal- 

 singham, grew to about half size and died ; their proper food may 

 perhaps be obtained in a future season. 



Orgyia, sp. inc. — Lord Walsingham deposited two larvae of an 

 unnamed Orgyia from North America. 1 was able to breed a line 

 specimen on the 26th instant, which has been preserved. 



Some mangolds infested with the larva of the Dipteron Anthomyia 

 betce were sent in reply to a request of mine, and exhibited with a 

 short notice.
