fluffy, yellowish moth, with a wing expanse of about an 

 inch and a quarter or a little more; the front wings have 

 irregular brownish markings near the front margin and 

 rows of fine, curly, hair-like scales; the body is thick and 

 woolly. 



PYROMORPHID..E 



These are small, blackish moths, often with brilliant 

 markings, most of our species having a red collar. 



If you have ever seen these larvae on the 



leaves of grape or Virginia creeper (Plate 



LIX), you will recall the sight, but there 



are other larvae which feed on other plants in the same 



orderly fashion. This species pupates in a white oval 



cocoon underground. Some of the adults emerge, after a 



pupal existence of only about two weeks, but other pupae 



winter over. The yellow eggs are laid in loose clusters 



of about a hundred on the under side of the food-plant's 



leaves. 



COSSID^E 



The adults' appearance suggests Sphingidae but they 

 have a very small head and almost no tongue; furthermore, 

 they, especially the females, are very feeble fliers. All 

 the strength seems to be in the larvae, w r hich bore in the 

 wood of trees. The adults are sometimes called Goat- 

 moths, presumably on account of their odor. 



The Leopard-moth is an immigrant from 

 .euzera Europe, undesirable but interesting, which 



is still largely confined to the vicinity of 

 New York City. The adult male (Plate LX) is only 

 about two thirds as large as its mate; the semitransparent 

 wings of each are white, spotted with black. The grub- 

 like larva is pale yellowish, sometimes pinkish, except 

 for numerous brownish-black spots. They bore in almost 

 any tree and in many shrubs. If the young larva starts, 

 as it usually does, in a twig which is too small for its con-
