LABELING THE EXAMPLES. 



PAPILIO TROILUS. 



Linn. Mus. Ulr. p. 187, (1764). 



Bucks Co., Pa. 



PAPILIO COPANJE. 



Reak., Proc. Ent. Soc., Phila. II, p. 141, 



(1863). 



Copan. (Orig. type.) 



The above is the most exhaustive way of labeling, but will save you much 

 future trouble ; you may, however, shorten it by leaving- out the work in 

 which it was first described, thus : 



PAPILIO TROILUS. 



Linn. 



Bucks Co., Pa. 



PAPILIO COPA1SLE. 

 Copan. Reak. 



(Original type). 



Always remember that the name of the author is as necessary as that of the 

 species. 



If you don't know the name at all, never neglect to state the locality ; when 

 you have the same species from different localities you can have smaller labels 

 for each locality, only using the large label with the name for the first two of 

 a species, and giving each of the other localities one of the smaller labels, 

 thus: 



PIERIS OLERACEA, 



Harr. 



Trenton, N. J. 



Ontario, Canada. 



Great Slave Lake. 



Labrador. 



Massachusetts. 



These labels are fastened to the bottom of the drawer or box, directly 

 above the specimens of the insect designated, by a short pin at each end. 



Many Lepidopterists collect the species of their own country or locality 

 only, others, those having the greatest collections, place the species from afl 

 countries together, which I hold to be the only proper way, as nature has not 

 set county lines in such matters, and the species of all parts of the world 

 are but links in the great chain, and by omitting those of some particular 

 country you break the chain, and must produce discordancy. In my own 

 collection, before referred to, I have placed those from all countries together, 

 thus: in the orange-colored forms of the Coliades I have them native and 

 foreign arranged in the following manner:
