NOTES AND OBSEEVATIONS. 



Re-appearance of Aporia crat^egi. — Mr. Douglas Stockwell de- 

 serves the thanks of all lovers of butterflies, and of all true entomo- 

 logists, for refraining from the publication of a more precise locality 

 than the county in which Aporia cnxt(r,gi has been captured this year 

 {ante, p. 332). The county is enough for scientific purposes; and 

 doubtless Mr. Stockwell can, if challenged by entomological authority, 

 give any particulars required in the way of evidence, and in such a 

 manner as would baffle the dealer and omnivorous collector. It is 

 fortunate that Mr. Stockwell has followed the example of the editor of 

 the 'Field' rather than that of Mr. Frohawk {vide Entom. xxv. 217).

 court-Bath's suggestion that varietal names should be given to every 

 form of Parnassius apollo which he or others think they can separate. 

 We have already a great deal too many named varieties of European 

 butterflies, many of which can only be distinguished when what some
