velvety-black ; on the front pair, between tlie two spots before and 

 below, and sometimes above the inner one and behind the outer, are 

 lines or spots of violet-colored scales 

 of a rich metallic lustre; the two spots 

 of the front wings are pale yellow, and 

 those of the hind pair, white. The 

 thorax and abdomen are black, the for- 

 mer with a small yellow spot just behind 

 the head, and yellow shoulder-covers 

 shading paler toward their tip; the 

 abdomen is marked with a small yellow 

 tuft medially on its basal segment, and 

 in the male with a few whitish hairs on 

 the middle of each segment and a tri- 

 angular-shaped white tuft on the seg- 

 ment before the last. The 

 (shanks) of the anterior and middle pairs of legs are clothed with long, 

 deep orange-colored hairs. In the male, in front of the anterior 

 legs, are two rather long, yellowish-white tufts. 



In Eudryas grata, the anterior wings are pure white within. The 

 stripe extending half-way across their front and the broad band 

 crossing the outer margin are rusty-brown, bordered with olive- 

 green; the band is traversed by waved 

 lines of violet-colored scales of a metal- 

 lic lustre; on the middle of the inner 

 margin is a large triangular spot of 

 olive-green. The posterior wings are 

 dull yellow, with their hinder margin 

 bordered with brown. The head is 

 black. The thorax is crested with Fig. 9.-The beautiful woodnymph.

scales; the shoulder-covers are white. The abdomen is yellow, with 



a row of black spots centrally and on its sides. 



The Alypia Caterpillar. 

 The Alypia caterpillar has frequently proved a serious pest in cer- 

 tain parts of New York city in almost entirely stripping the grape- 

 vines of their leaves, and continuing the injury for several years in 

 succession. In some localities — in Albany and elsewhere, it is becom- 

 ing, or has already become, quite injurious to the ^mpelopns in eating 

 off its terminal shoots and thus arresting its extension. It may be 

 readily recognized from the representation given of it in Fig. 8, at a 

 and h, and the following statement of its principal colorational featurep. 

 The head is yellowish, with about eight black dots on each side. The
