'The Hickory Tiger" is one of the 

 English names of this species (Plate L) 

 and, like the specific name, refers to the 

 larva's fondness for hickory leaves but, as a matter of 

 fact, it feeds on other trees also. It has also been called 

 Tussock Moth, but that name should be reserved for a 

 species of Liparidas whose larvse these resemble. The 

 cocoon, which is made in some sheltered nook, is composed 

 of larval hairs pushed through a very thin envelope of silk. 

 The author of Insect Lives; or Born in Prison quaintly 

 describes the color of the moths as being the same as that 

 of hickory-nut meat. 



Halisidota tessellaris is much like caryce but the larva has 

 no "black buttons down the back" and its body hairs are 

 usually tinged with yellow or brownish ; the adult tessellaris 

 is much paler, being pale straw-color, and has bluish- 

 green lines on the thorax. The larva is sometimes too 

 common in our gardens and on shade trees. That descrip- 

 tion of the adult also fits the southern cinctipes, which is 

 larger and has the lower part of its legs gartered with 

 black. The western argentata has the white spots silvery 

 and the ground color of the front wings dark brown. The 

 adult of the northern maculata might be loosely described 

 as like carytz except that the white spots are dark spots. 



AGARISTID^: 



Members of the genus Alypia are called 



ypia Foresters; translating the specific name, 



octomaculata . 111,1 T-- 1,4. 



this species (Plate L) is called the Eight- 

 spotted Forester. Its larva, which feeds on the leaves of 

 grapes and of the Virginia creeper, is orange, yellow^ 

 black, and white; it has a hump near its tail. Pupation 

 occurs in a very thin cocoon of chips and silk at, or slightly 

 below, the surface of the ground; or the larva may gnaw 

 into wood to pupate. The velvety-black adult has yellow 

 spots on the front wings, white on the hind. It frequently 

 flies by day. Although the Eight-spot is confined to the 

 northeastern quarter of the United States, other sections 

 have similar species.
