LEPIDOPTERA. 291 



Early attention and perseverance in the use of these remedies 

 will, in time, save the farmer hundreds of dollars, and abun- 

 dance of mortification and disa))pointmcnt, besides rewarding 

 him with the grateful sight of the verdant foliage, snowy blos- 

 soms, and rich fruits of his orchard in their proper seasons. 



Another caterpillar, whose habits are similar to those of the 

 preceding, is now and then met with, in Massachusetts, upon 

 oak and walnut trees, and more rarely still upon apple-trees, 

 and cherry-trees. According to Mr, Abbot " it is sometimes 

 so plentiful in Virginia as to strip the oak-trees bare ;" and I 

 may add that it occasionally proves very injurious to orchards 

 in Maine. It may be called Clisiocampa sihafica, the tent- 

 caterpillar of the forest. With us it comes to its full size from 

 the tenth to the twentieth of June, and then measures about 

 two inches in length. There are a few short yellow hairs scat- 

 tered over its body, particularly on the sides, where they are 

 thickest. The general color of the whole body is light blue, clear 

 on the back, and greenish at the sides; the head is blue, and 

 without spots ; there are two yellow spots, and four black dots 

 on the top of the first ring ; along the top of the back is a row 

 of eleven oval white spots, beginning on the second ring, and 

 two small elevated black and hairy dots on each ring, except 

 the eleventh, which has only one of larger size ; on each side 

 of the back is a reddish stripe bordered by slender black lines ; 

 and lower down on each side is another stripe of a yellow 

 color between two black lines ; the under side of the body is 

 blue-black. This kind of caterpillar lives in communities of 

 three or four hundred individuals under a common web or 

 tent, which is made against the trunk or beneath some of the 

 principal branches of the trees. When fully grown they leave 

 the trees, get into places sheltered from rain, and make their 

 cocoons, which exactly resemble those of the apple-tree tent- 

 caterpillars in form, size, and materials. The moths appear in 

 sixteen or twenty days afterwards. They are of a brownish 

 yellow or nankin color; the hind wings, except at base, are 

 light rusty brown ; and on the fore wings are two oblique rust- 

 brown and nearly straight parallel lines. A variety is some- 

 times found with a broad red-brown band across the fore
