APPLE. LEATES. 



take on difterent colors and marks with every change of their 

 skins, so that a description of the full grown worm will not apply 

 to it when it is small. Quite a number of these worms are yet 

 unknown to us in their perfect state. Of those mentioned below, 

 the eight first are caterpillars, clothed more or less densely with 

 hairs; the four next are large thick bodied worms, and the re- 

 mainder are small and more slender. 



28. Apple-tree caterpillar, Clisiocampa^mericana, Harris. (Lepidoptera. 

 Bombycidae.) 



In May, forming large cobweb-like nests in the forks of the 

 limbs; black, hairy caterpillars with w^hite lines, and along each 

 side a row of blue spots; living together in societies; finally dis- 

 persing and spinning oval white cocoons, placed in sheltered cor- 

 ners. The moth appearing the first of July, dull brownish red, 

 its fore wings crossed by two straight white bands running parallel 

 with the hind margin. Width of the wings when spread, 1.20 

 to 2.00. See Transactions of 1855, p. 413. 



Forest caterpillar, Clisiocampa sylvatica. See Oak insects. 

 Fall web worm, Ilyphantria textor. See Cherry insects, No. 88. 

 Hickory tussock moth, Lophocampa Carycz. See Walnut insects. 



29. Yellow-necked apple-tree worm, Eametopona Ministra, Drury. 

 (Lepidoptera. Notodontidse.) 



Clustered closely together and wholly stripping the leaves from 

 a particular limb, in August; when alarmed holding both ends 

 of their bodies stillly upward; dull yellow, cylindrical worms 

 thinly clothed with long soft hairs, with light yellow stripes and 

 black heads, when older becoming black with a yellow neck and 

 liglit yellow stripes. The moth varying from buff* yellow to 

 auburn brown, its fore wings crossed by three to five narrow 

 brown or blackish bands, the forward one curved and transverse, 

 the other straight and parallel with the hind margin. Width 

 2.00 to 2.40. See Transactions, 1855, p. 467. 



30. AMKUirAV LAPPKT MOTH, Gastropacha j^mericana, Harris. (Lepidop-
