It is never amiss to have the same species represented by examples from 

 various localities, as it is vastly interesting to see what changes may be pro- 

 duced by climatic and other causes, as for instance Limenitis Misippus, which 

 is red in the northern States, the same colour as Danais Erippus, is very dark 

 brown almost blackish in Florida, where it resembles another species of 

 Danais called Berenice ; and the female of the Central American form of 

 Papilio Asterius has a broad sub-marginal band or row of yellow spots on all 

 the wings like the male, whilst the female in the common United-States form 

 is almost altogether devoid of these spots; in the female of the same species 

 from Labrador the yellow band is broader even than in those from Central 

 America, which is still more curious when we consider that in those found in 

 the United States, between the two extremes of Labrador and Central Amer- 

 ica, the female is destitute of the macular band, or has it represented only 

 by a few small, half-obsolete spots. 



ON CLEANING SPECIMENS. 



Sometimes a butterfly or moth will be found to be more or less greased on 

 body and wings, always starting at body and extending over the wings more 

 or less, defacing and altogether hiding their beauty. This may be entirely 

 removed by the following process : get a wide glass jar, need not be very deep, 

 put a thin slab of cork in the bottom, the cork should be a trifle larger than 

 the inside of the jar, so that it will take a little gentle squeezing to get it 

 down to the bottom tight that it cannot move ; pour the best refined benzine 

 into the jar to the depth of two inches or so, and pin your greasy specimen 

 on the cork in the bottom of jar so that it will be entirely covered with the 

 benzine, then cover the top of jar, and let it rest a longer or shorter time a 

 half an hour generally suffices, but if very bad they need a longer time ; when 

 you think the specimen was in long enough, take it carefully out by the pin, 

 and pin it on a piece of cork, stand it in some safe place where it ain't dusty, 

 and do not be frightened at the desolate, slunk appearance of your specimen, 

 for no matter how bad it looks, depend on it, it will come all right ; just let 

 it alone ten or fifteen minutes, and you will find it beautiful, brilliant, and
