the Callidium amenum Say (fig. 98). Its larva is represented by 
figure 81, b, upper, c, under side of the head. 
One of the most wonderful cases of mimicry is that of a new 
span worm Drepanodes juniperaria Pack. (fig. 82 ; 83, larva and 
chrysalis) which can with difficulty be distinguished from the twigs 
of the juniper tree on which it feeds. 
The cedar also has been found to be infested by a small Tinean, 
closely allied to the Apple Bucculatrix. This is described as the 
B. thuiella (fig. 84, enlarged; a, cocoon, nat. size). The trans- 
formations of Telephorus 
bilineatus Say (fig. 96; 
larva, enlarged, and ad- 
joining fig. 97 showing a, 
upper, and b, under side 
of the head) are also de- 
scribed. The larva was 
identified by Mr. P. S. 
Sprague, who found it

where it changes to a 
pupa, and early in May 
becomes a beetle, when 
it eats the leaves of the 
birch. 
Among beneficial insects are mentioned the ground beetle, Ga- 
lerita Janus Fabr. (fig. 95) whose singular larva (fig. 94, a, upper; 
b, under, side of the head), was discovered by Mr. J. H. Emerton 
undér stones early in July. The larve of two dragon flies, Cor- 
dulia lateralis (fig. 93) and a species of Didymops? (fig. 99) are 
also noticed.
