The grape-vine epimenis, Psychomorpha epimenis.- — This is a vel- 

 vety-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. 873). The larva re- 

 sembles somewhat that of Alypia figured 

 on a later page, but it is bluish and has 

 only four light and four dark stripes 

 on each segment. It feeds upon the ter- 

 minal shoots of grape and Virginia-creeper 

 in spring, drawing the leaves together by 

 a weak silken thread and destroying them. 

 When ready to transform, which is us- 

 ually 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-n^Tnph, Eidhisandtia grd- 

 fl^y i^ C O ff ^ ^ /a.— This moth (Fig. 874) well deserv^es the popu- 

 ^I^M^Mj ^^ ^ lar name that has been applied to it. Its front 

 ^^npwd|^| wings are creamy white, with a glassy surface; a 

 ^^f M ^p^ wide brownish purple stripe extends along the 

 costal margin, reaching from the base to a little 

 be^-ond the middle of the wing, and on the outer 

 margin is a band of the same hue, which has a 

 wavy white line running through it, and is margined 

 internally with a narrow olive-green band. On the inner margin is a 

 yellowish olive-green cloud. The hind wings are pale ochre- 

 yellow, with a brown band on the outer margin. The wing expanse 

 is about 40 mm. 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 resemblance to that of Alypia, 

 but may be distinguished by having on- 

 ly six transverse black lines on each seg- 

 ment. It has the same food-plants as 

 the species described above. It trans- 

 forms in a cell in the ground or in soft 

 wood. 



The pearl wood-njrmph, Euthisanotia Unio. — This moth closely 

 resembles the species just described, but is smaller, expanding a little 

 less than 37 mm. The outer border of the front wings is paler and 

 mottled; and the band on the hind wings extends from the anal 

 angle to the apex. The larva resembles that of E. grata; it feeds upon 

 the leaves of Epilobium color atum, and perhaps on grape also. 



The subfamily Cuculliin^. — This subfamily is of considerable 

 size, 264 North American species are now listed. Among them are 

 the following.

Euthisanotia grala.
