haunting the crevices of the steep aiguilles, have served as modest 
factors in that process of disintegration which has hurled this vast 
burden of moraine upon the sea of ice—* Saxa-fraga, I break a 
stone,” says the etymologist. 
Some authorities affirm that the “semicolon,” which is so 
wonderfully discriminating in the Nettle family, as already shown, 
is occasionally found on the Linden. I have never happened to 
verify this statement. It is certainly not a common choice of the 
insect in the localities which I have frequented, and I half sus- 
pect that the placing of that Linden” egg was a case of careless 
mispunctuation on the part of the “semicolon” (if not of the au- 
thor), or may be referred to some lapsing ancestor which has 
bequeathed his degeneracy to a single small line of descendants. 
In a former work I have alluded to those pretty petal bowers 
upon the everlasting in which the spiny, white-spotted caterpillar 
of the hunter’s butterfly lies concealed by day, or hangs its jew- 
elled chrysalis—of all its tribe the true model of the poet: 
“T’d be a butterfly born in a bower.” 
Other observers have found the larve on many plants of the 
same genus only, and in the one next allied, Axdexnaria. But 
Scudder says the “forget-me-not,” an unassociated plant, is also 
included among its diet. There is some mistake here. Let us 
hope that the fickle deserter may yet listen to the message of the 
Flora Symbolica, and return to its deserted immortelles. 
Our Painted Lady butterfly is another interesting exception, as 
showing a dual botanical mission in selecting the plants of two 
natural orders, and never going outside of them, representing, 
doubtless, an hereditary choice in each given brood, rather than 
mixed impartially in one. The caterpillar is quite commonly found 
upon thistles of all kinds, constructing a web-tent hung from the 
spiny points of the leaves, whence it emerges at night to feed. 
“It is found, also,” says an authority, “on sunflower, hollyhock, 
burdock, and other rough-leaved plants,” but these other “ rough- 
leaved plants” could most certainly be traced to one of the two
