41 ARTICULATES : INSECTS. 



P. pomonella, Harr., which expands three fourths of an 

 inch, and the fore wings are crossed by gray and brown 

 lines, and near the hind angle is a large dark spot with 

 bright copper-colored edges ; hind wings and abdomen 

 light yellowish-brown with a satin lustre. The larva 

 is the well-known apple-worm, which every child has 

 seen. During the latter part of June and in July the 

 moths fly about apple-trees every evening and lay their 

 eggs in the cavity at the blossom end of the little apples. 

 The eggs hatch in a few days, and the little caterpil- 

 lars immediately burrow into the fruit. There is gen- 

 erally but one to each apple, and so small at first, that 

 it is detected only by the reddish powder it throws out 

 in eating its way through the calyx. In the course of 

 about three weeks it reaches its full size, and meanwhile 

 has burrowed to the core, and through the apple in vari- 

 ous directions. It bores a hole through the side of the 

 apple, out of which it thrusts its chips, and through 

 which the insect ultimately escapes. Soon after the 

 half-grown apples fall, the caterpillars leave them, crawl 

 into crevices, and each spins a delicate white cocoon, 

 in which, in most cases, it remains till the next summer, 

 when it comes forth in the perfect form. 



TINEID^E, Leach, OR TINEA FAMILY. This Family 

 comprises moths which in the larva state gnaw wind- 

 ing paths in the substances upon which they subsist. 

 They devour some of the fragments, and fasten together 

 others with silken threads, thus making a covering for 

 their tender bodies. Some thus make cylindrical bur- 

 rows ; others make cases, which they bear about with 

 them. They are the smallest of the Lepidoptera, and 

 are generally very beautiful. 



The Genus Anacampsis contains the Angoumois Grain- 

 Moth, A. cerealella, Olivier, which expands half an inch, 

 and is pale cinnamon-brown above, with a satin lustre ;
