1881.] REPORTS ON THE INSECT-HOUSE. 823 



Arctia parasite. — Larvse of this species were deposited by Lord 

 Walsiugham, and all are now in pupa, kept in the cool studio. 



General liemarAs. — During the past month I have communicated 

 with many entomologists throughout the world ; and I hope by this 

 means that the Society will in due course receive many nice specimens 

 from abroad for the Insect-house. A correspondent in Rio (Mr. 

 Bonninghausen) has already expressed his willingness to assist, and is 

 for that purpose feeding up Attacus auratus aud other Saturniidse for 

 exhibition later on. I have also asked for cocoons of the giant 

 Cetonias Goliathus iorquatus &c., from a correspondent, Mr. Fuller, 

 of Caniaroons, West Africa. 



Report of the Insect-house from August \st to 

 September \7th, 1881. 



Case No. I. Samia glover i. — No alteration has occurred in this 

 rase since preceding report. 



No. 2. Samia cecropia. — The larvae of this species have not done 

 well in the house — those obtained from Brussels growing very slowly, 

 and diminishing by death till the last one died Sept. 8, having 

 only attained about half-growth. 



No. 3. Attacus cynthia. — Four cocoons were obtained from the larvte 

 hatched in July ; and a perfect insect appeared from one of these on 

 Sept. 4. A nice lot of the larvae, nearly full fed, are now in the 

 cage. 



No. 4. Attacus pernyi. — The cocoons obtained in July produced 

 fair-sized images for the summer brood; and throughout August living 

 moths were exhibited. A very large number of eggs were obtained. 

 These hatched on August 29 ; and there are now in this case and in 

 glass vessels about 300 larvae feeding up ; these will continue feed- 

 ing into November. 



No. 5. Attacus atlas. — Imagos were exhibited alive throughout 

 the month of August. 1 obtained four fair-sized cocoons from the 

 larvae reported on last month ; and these, I anticipate, will emerge 

 in October. These are now exhibited. 



No. 6. Attacus mylitta. — The sexes of this species not emerging 

 together, no fertile eggs were obtained from our stock. I procured a 

 few eggs from a correspondent ; but these were not fertile ; so I pro- 

 cured 50 small larvae, which are now feeding nicely, aud will, I hope, 

 produce cocoons, although started so late ; however, they feed nicely 

 upon the evergreen oak, which can be procured as long as required. 



No. 1 . Actias selene. — No change has taken place in this case 

 since my last Report. 



No. 8. Actias tuna. — The same remark applies to this case as to 

 no. 7 ; as, however, both hold cocoons that appear alive, they had 

 best be retained as they are. 



No. 9. Telea promethea. — No change has been made in this case. 



No. 10. Anthercea yama-mai. — No more cocoons have emerged. 



No. 11. Attacus auratus. — My friend, Mr. Bonninghausen, of 

 Rio, has sent me 8 cocoons of this fine species (hitherto not 

 recorded as bred iu this country) by post; on arrival 5 were found
