fouucl in October, changed to pupa same month, collecting two or three 

 leaves and making a kind of envelope of the powder ; imago made its 

 appearance in June following." 



In a letter dated " Shanghai, 3rd August, 1870," Mr. Holdsworth men- 

 tions that both Pcxpilio Xuthus and P. Xuthulus are found in that neigh- 

 bourhood ; and referring to the silk-worm cocoons mentioned ante, p. xxi., 

 writes as follows ; — " I am glad the boxes of cocoons reached you, and 

 I hope the moths have come out successfully long ere this ; all mine came 

 out at the end of April and first week of May. I failed to rear any larva?, 

 owing to not being able to procure the proper oak. The moths out of the 

 Honan cocoons are very little different to those from Szechuen, the chief 

 distinction being the ground colour of the wings." As previously conjectured, 

 both the Honan and Szechuen cocoons were doubtless the same species, 

 Bombyx Pernii; of those sent by Mr. Holdsworth to this country, Mr. 

 Dunning mentioned that he had not reared a single moth, and that 

 the same fate had attended Mr. Shoolbred appeared from the following 

 letter. 



The Secretary read the following extract from a letter from Mr. W. A. 

 Shoolbred, jun., dated 29th August, 1870:— 



" I am sorry to say that not one of my Pernyi cocoons has produced a 

 moth. I hope you have had better success. I at first hung mine up in a 

 cool greenhouse in the sun, along with cocoons of B. Cynthia and Cecropia. 

 One day I fancied, from the way that one of the cocoons rattled on being 

 shaken, that the pupa inside must be dead. On cutting open the cocoon 

 I found it was so ; one or two others which I opened were also dead, and 

 another or two looked doubtful, but none of them looked decidedly alive. 

 Thinking they might be too hot, 1 moved them into a shady place in the 

 greenhouse. Seeing that they did not emerge, I opened two or three others 

 some time afterwards, and they were dead. I have now given up all hope 

 of any emerging. This year I have been very successful with Cecropia ; 

 some of the larvae are enormous, about the size of the larvae of Acherontia 

 Atropos. I have kept them out of doors, on branches of apple trees 

 protected with bags of coarse muslin. Cynthia has not done so well this 

 year ; on account of the larvae having demolished all my Ailanthus foliage, 

 I have had to finish them off on laburnum and castor-oil plant, and they 

 have not profited by the change. I have tried Saturnia Pavonia-major 

 this year, but have only reared three worms to cocoons, out of fifty eggs."
