258 INSKCIS INJURIOUS TO THE GRAPE. 



the breathing-pores oval, yellow, and margined with dull 

 black. Under surface pale pinkish green, feet black, proleg& 

 pink, with a patch 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.

 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-

the anterior margin, reach-

 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 deep-green edging on its inner side. 

 The l)rownish-])urple band is continued along the hinder 

 edge, but gradually becomes narrower, and terminates when
