can be readily distinguished by the hind wings bearing only 

 a single spot. It is not a common species, and its early 

 stages have not yet been described. 



The Grape-vine Epimenis, Psychoniorpha epimenis (Psy- 

 ch o-mor'pha ep-i-me^nis). — This is a velvety-black species 

 with a large white patch on the outer third of the front 

 wings and a brick-red patch on the hind 

 wings (Fig. 382). The larva resembles 

 somewhat that of Alypia figured above; 

 but it' is bluish and has only four light 

 and four dark stripes to each segment. f,^_ .z,,-P,ychomorj>hv 

 It feeds upon the terminal shoots of epimems, 



grape and Virginia-creeper in spring, drawing the leaves to- 

 gether by a weak silken thread and destroying them. When 

 ready to transform, which is usually towards the end of May, 

 it either enters the ground or bores into soft wood to form a 

 cell. Within this it remains until the following spring. 



The Beautiful Wood-nymph, Euthisanotia grata (Eu-this- 

 a-no'ti-a gra'ta). — This moth (Fig. 383) well deserves the 

 popular name that has been applied to it. Its front wings 

 are creamy white, with a glassy surface ; a wide brownish- 

 purple stripe extends along the cost',d margin, reaching 



from the base to a little beyond 

 the middle of the wing, and on 

 the outer margin is a band of 

 thesame hue, which has a wavy 

 white line running through it, 

 and is margined internally with 

 a narrow olive-green band.

lowish olive-green cloud. The hind wings are clear pale 

 ochre-yellow, with a brown band on the outer margin. The 

 wing expanse is about one and three-fourths inches. The 

 moth appears during the latter part of June or early in 

 July. The larva of this species is pale bluish, crossed by 

 bands of orange and many fine black lines. It also bears a
