LETTER OF OCTOBER 4TII, 1859. 23 



If you receive this lot of cocoonets safely, it will be prefer- 

 able to sending the perfect insects, both to you and myself. 

 You can then set out your own specimens, for it is an act in 

 which I am not yet proficient. 



I beg you will pardon the informality of this scrip* almost 

 a transatlantic despatch, and believe me, &c. 



P.S. — The P. vitigcnella have just formed their cocoons. 

 They will appear in about a fortnight from this date ; per- 

 haps one may come out before this box reaches you. Two 

 specimens are in the larva state yet, but are preparing to 

 form their cocoons. On the top I add a few cocoonets of a 

 new genus, Aspidisca splendor if erella.

 Micros. I hope you will receive them safely, and that their 

 confinement and transatlantic voyage may not injure the pupae. 

 I do not desire any return for them, nor was the box sent 

 under any expectation or hope that you might be induced to 

 make a return of your own insects. The hope that I may 

 thus give you some pleasure in return for your kindness and 

 courtesies is a sufficient remuneration, and I dare say the 

 satisfaction and pleasure I had in sending quite equals what 

 you will feel on their reception. Should the pupae of this 

 lot produce imagos, I Avill gladly send you others hereafter. 

 This I can easily do, probably during the summer, as but ten 

 days at most will expire before they reach you, and my 

 observations, during the last and the present summer, have 

 put me in possession of the history of many larva?. Some of 

 them are very troublesome to rear, and in many instances
