258 INSECTS INJURIOUS TO THE GRAPE. 



the I )rea thing-pores oval, yellow, and margined with dull 

 black. Under surface pale pinkish green, feet black, prolegs 

 pink, with a j)atch of black on the outside of each. 



This description of the larva was taken from three speci- 

 mens found feeding on a grape-vine early in July. One of 

 them matured and formed a slight cocoon of leaves fastened 

 with silken threads on the surface of the ground, after the 

 manner of the green grape-vine sphinx, No. 132; the other 

 two died before completing their transformations. This larva 

 is said to feed also on purslane ; it is not nearly so common 

 as lineata, and is not likely ever to prove injurious to any 

 considerable extent. 



No. 138. — The Beautiful Wood-nymph. 



Eudryas grata (Fabr.). 



The larva of this lovely moth is quite destructive to the 

 foliage of the vine, upon which the moth itself is often found 

 resting during the daytime, its closed wings forming a steep 

 roof over its back, and its fore legs, which have a curious 

 muff-like tuft of white hairs, protruded, giving the insect 

 a very singular appearance. When its wings are expanded, 

 they measure about an inch and three-quarters across. (See 

 Fig. 268.) Its fore wings are creamy white, with a glossy 



surface; a wide brownish- 

 Fia. 268. purple stripe extends along 



the anterior margin, reach- 

 ing from the base to a little 

 beyond the middle of the 

 wing, and on the outer mar- 

 gin is a broad band of the 

 same hue, widening poste- 

 riorly, and having a wavy 

 white line running through it, formed by minute pearly dots 

 or scales, and a dull dee])-green edging on its inner side. 

 The brownish-purple band is continued along the hindei 

 edge, but gradually becomes narrower, and terminates wheD
