Tortricidse 
which is lodged the larva of a species of Tortricid, which has the 
power, by changing its position on the inside of the seed, of 
making the seed move. In the case of Croton seeds the insect is 
Cydia saltitans Westwood; in the case of Sebastiania seeds the 
insect imparting the motion to the thing is the larva of Enar- 
mon ia sebastia n ice. 
It is quite impossible for us in a work of the present scope to 
give even an epitome of the nearly five hundred species of Tor- 
tricids which are at present known to occur within the limits of 
the United States and Canada. We shall content ourselves with 
an account of a few species, which will serve to show the reader 
what a mine of interesting inquiry presents itself to view in this 
single family of beautiful little moths. 
Genus EUCOSMA Hiibner 
(i) Eucosma scudderiana Clemens. (The Misnamed Gall- 
moth.) 
Syn. saligneana Clemens ; affusana Zeller. 
The moth was called “ the Misnamed Gall-moth ” by Professor 
Riley because Clemens 
had given it a specific 
name which implied that 
it was a denizen of wil¬ 
low-trees or willow- 
galls, when in fact it has 
been ascertained to live 
in the galls of the Golden- 
rod (Solidago). The in¬ 
sect is not uncommon in 
western Pennsylvania, 
and is possibly an inqui- 
line or intruder in the 
galls, which are pro¬ 
duced by another spe- 
Riley.
