238 INJDEIOUS INSECTS 



and 11 — running just below the spiracles, and interrupt- 

 ed by the transverse orange band. 



This larva transforms to chrysalis within a very slight 

 cocoon formed without silk, upon, or just below, the sur- 

 face of the earth, and issues soon after, as a very beautiful 

 moth of a deep blue-black color, with orange shanks, 

 yellow shoulder-pieces, each of the front wings with two 

 large light yellow spots, and each of the hind wings with 

 two white ones. Figure 142, c, represents the female, and 

 the male differs from her in liaving the wing spots larger, 

 and in having a conspicuous white mark along the top 

 of his narrower abdomen. 



We have on one or two occasions known vines to be 

 partly defoliated by this species, but never knew it to be 

 quite so destructive as it often is in some Eastern local- 

 ities. In New York City the vines in the yards are often 

 completely stripped of their foliage through the agency 

 of this and related caterpillars. 



THE BEAUTIFUL WOOD NYMPH. 

 (Eudryas grata, Fabr). 



Here is another moth which surpasses in real beauty, 

 though not in high contrast, the species just de- 

 scribed. The front wings are milk-white, broadly bor- 

 dered and marked on their margins with rusty-brown, 

 the band on the outer margin being shaded on the inner 

 side with olive-green, and marked towards the edge with 

 a slender wavy white line : under surface yellow, with two 

 dusky spots near the middle. The hind wings are nan- 

 kin-yellow, with a deep-brown border, which does not 

 extend to the outer angle, and which also contains a 

 wavy white line: under surface yellow, with a single 

 black spot. 



Surely these two moths are as unlike in general appear- 

 ance as two moths well can be; and yet their caterpillars
