28 THE ENTOMOLOGIST. 



only confirms my opinion respecting the specific identity of 

 A. Adippe and A. Niobe : the two insects only differ in a 

 character which, with my Swiss specimens, I could show to 

 be variable ; and surely, if two of our chief British lepi- 

 dopierists are disagreed as to the parentage of the New- 

 Forest specimen, a question may well be raised as to the 

 distinctness of the two so-called species. If the specimen 

 which I saw is the individual mentioned in the 'Entomo- 

 logist,' I have no hesitation in supporting Mr. Doubleday, 

 and pronouncing it a true Niobe ; but I would not disagree 

 with Mr. Bond in considering it more than a variety of 

 A. Adippe. In a short paper recently pubhshed in the 

 'Entomological Transactions' 1 made a remark respecting 

 the probable identity of the two species ; unfortunately I 

 inadvertently wrote " Aglaia" for "Adippe." — A, G. Butler ; 

 Bri/ish Museum, January 1, 1870. 



[I believe there is no doubt, among continental entomo- 

 logists, that Argynnis Niobe and A. Adippe are perfectly 

 distinct as species; and 1 know from a letter of Mr. Double- 

 day's, now before me, that he entirel}^ agrees with this 

 opinion. The larvae of the two species are different: Hiibner 

 figures that of Adippe on the dog-violet (Viola canina), and 

 that of Niobe on the wild heartsease (Viola tricolor). The 

 upper surface of Niobe is almost exactly like that of Aglaia, 

 while the under surface resembles that of Adippe. There is 

 a variety of Adippe without silver spots. The question 

 asked by Mr. Butler, whether the specimen mentioned by 

 Mr. Hambrough (Entom. iv. 351 and v. 17) is the same as 

 one shown to him at the British Museum, may, I think, be 

 answered in the affirmative, for Mr. Hambrough distinctly 

 says of his specimen, " On taking it to the British Museum," 

 &c. — E. Newmau.] 



Bonibyx Pernyi {Silk-moUi). — Two years ago I recorded 

 in the ' Entoujologist ' my experience in rearing Bombyx 

 Yauja-mai, and last year that of B. Cynthia. I will now, 

 with the Editor's permission, do the like with B. Pernyi. On 

 the •29th of May, 1809, I received from Dr. Wallace newly- 

 deposited eggs of B. Pernyi : these were, of course, from 

 moths which had passed the winter in the pupa state. 

 Hatching commenced on the 22nd of June, about eight- 

 tenths proving fruitful. By an unfortunate accident I lost a
