INSECTA. 149 



measures an inch across,* from outspread wing to wing; 

 upper wings, or elytra, reddish-gray, marked with angu- 

 lar lines, the lower brown, and dark on the borders, 

 both fringed on the edges, body reddish-gray. The 

 caterpillar, which is hairy, and at first a dirty olive 

 color, which afterwards changes to gray, lives on the 

 tender branches of the pines, and renders them crooked. 

 Thus, they are very injurious. They envelope them- 

 selves in a brown cocoon placed in a crevice of the bark, 

 where they remain all winter. 



The Resin Moth (tinea resinella) is brown, nearly 

 black ; under wings lighter, with pale-fringed borders ; 

 upper wings silver-gray, and marked with bands ; eight 

 lines in length. The caterpillar, brown and hairy, bores 

 into the fir trees, thus forming galls, in which the brown- 

 ish-black pupa awaits its transformation, and in early 

 spring comes forth winged. 



The Apple Tree Moth (tinea pomonella) measures 

 nine lines ; body and upper wings gray, striped with 

 brown, and adorned on each side with a coppery, eye- 

 . shaped ring; lower wings reddish-brown, bordered with 

 gray; the caterpillar, or larva, naked, and of a pale 

 yellow color, bores into the fruit, even to the seeds, of 

 apples and pears, thus destroying them. In July these 

 larvee come forth, and fixing themselves in the crevices 

 of the bark, spin a thick, silky cocoon, in which the 

 pale brown pupa remains all winter. They are very 

 injurious. 



The Common Corn Moth (tinea granella) measures 

 from six to seven lines ; the wings are small, fringed, 

 and when at rest elevated behind. Body and posterior 



* This measure always relates to the expanse of wings.
