by Lord Walsingham on the 4th instant. Four have spun up in 

 the moss and, 1 hope, changed to pupfc ; but it is best not to disturb 

 them at present. One has died. This cage now contains the larvae 

 of Attacus atlas. 



No. 13. Papiiio machaon. — Small larv?e were obtained from tlie 

 Cambridge fens on the first day of tlie month and placed in the 

 cage. Tliey grew rapidly, feeding upon carrot-top, and spun up in 

 10 days ; they are now (August) emerging perfect and of full size. 

 This is the second brood of this species. All the pupoe obtained 

 changed on the top of the cage, and were not, as usual, of a pale 

 yellow-green deepening to a fine dark green along the back, but were 

 dirty white, changing to a dark amber-colour along the back. I 

 have seen pupas of this species of the same colour from Germany and 

 France (reared in confinement), but only very rarely in England. 



No. 14. Beilephila ewphorbice. — Pupa) of this species emerged 

 during the month in fine condition ; and the imagos were much 

 admired. Two of these were observed hovering over the flowers in 

 a most natural manner. 



No. 15. Erebia medea. — The larvse of this species placed in the 

 cage in June produced fine imagos almost every day during July. 



No. 16. Lyccena conjdon. — Larvas of this pretty little Butterfly 

 were obtained from Canterbury and fed up, changing to healthy 

 pupse, and producing many imagos during the early part of the 

 month. The cage is now tenanted with iSmerinthus ocellatus. 



No. 17. Pohjommatus phleas. — Larva? of this little Butterfly were 

 obtained and placed in the cage, and fed upon Eiime.v ; they pro- 

 duced perfect specimens about the middle of the month for some 

 days. After this species was over, the cage was stocked with Sphinx 

 Jiyustri. 



No. 18. Saturniu carpini. — Larvae obtained from eggs spun up 

 on the 17th instant; a further supply of larvae which was obtained 

 produced cocoons about the same time, a nice lot of which are reserved 

 for next spring. 



No. 19. Vanessa antiopa. — Larvae of various growths and pupaR 

 of this species were obtained from Germany ; and imagos appeared 

 from the 21st instant, the three stages being exhibited alive. The 

 imagos feasted upon over-ripe plums placed in the cage for them. 



No. 20. Zygoma filipendula. — Larvae and pupae of this species 

 were obtained from the South coast, and the imagos emerging in a 

 few days made a very pretty exhibition during most of the month 

 in this cage. 



No. 21. Chcerocampu elpenor. — A full-fed larva of this species 

 was presented by Mrs. Frances Smith on the 16th instant, having been 

 found in her garden devouring the fuchsias ; it spun up under the 

 moss the tbllowiiig day. A further supply of the larvae was obtained 

 a few days later ; some of them have spun up ; others are still feeding 

 upon Virginian Creeper, an excellent substitute for Galium, their 

 usual food-plant. 



No. 22. Lasiocampa quercifolia. — Imagos of this species have 

 been exhibited throughout the month ; many fertile eggs were also
