THE BEAUTIFUL WOOD NYMPH— Eudryas grata, Fabr. 

 (Lepidoptera, Zygaenidae.) 



Here is another moth (Fig. 56), surpassing in real beauty, though 

 [Fig. 56.] no t i u high contrast, the species just de- 



scribed. The front wings are milk-white, 

 broadly bordered and marked, as in the 

 figure, with rusty-brown, the band on the 

 outer margin being shaded on the inner 

 side with olive-green, and marked to- 

 wards the edge with a slender wavy white 

 line : under surface yellow, with two 

 dusky spots near the middle. The hind wings are nankin-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 appearance as 

 two moths well can be ; and yet their caterpillars bear such a close 

 resemblance to each other, and both feed upon the Grape-vine ! The 

 larva of the Beautiful Wood Nymph is, in fact, so very similar to that 

 of the Eight-spotted Forester, that it is entirely unnecessary to figure 

 it. It differs more especially from that species by invariably lacking 

 the white patches along the sides, by the hairs arising from the black 

 spots being less conspicuous, and by the hump on the eleventh seg- 

 ment being more prominent. The light parts of the body have really 

 a slight bluish tint, and in specimens which I have found, I have only 

 noticed six transverse black stripes to each segment. This larva, 

 when at rest, depresses the head and raises the third and fourth seg- 

 ments, Sphinx-fashion. It is found on the vines in the central por- 

 tion of the State as early as May and as late as September, and it de- 

 vours all portions of the leaf, even to the midrid. It descends to the 

 ground, and without making any cocoon, transforms to a chrysalis, 

 which is dark colored, rough, with the tip of the abdomen obtusely 

 conical, ending in four tubercles, the pair above, long and truncate, 

 those below broad and short (Packard). Some of them give out the 

 moth the same summer, but most of them pass the winter and do not 

 issue as moths till the following spring. 



THE PEARL WOOD NYMPH— Eudryas unio, Huebner. 

 (Lepidoptera, Zygaenidae.) 



This is another pretty little moth, so closely allied to, and so 

 much resembling the preceding species, that it is not necessary to 

 produce its picture. It is a smaller species, and differs from the Beau- 

 tiful Wood Nymph in having the outer border of the front wings paler 

 and of a tawny color, with the inner edge wavy instead of straight ;
