324 INSECTS INJURIOUS TO VEGETATION. 



the lip; behind a deep notch of this band, near the base of the 

 wing, there is a triangular tawny spot, and another smaller 

 one near the tip. The green band is sometimes broken into 

 three triangular green spots, the middle one of which is wanting 

 in some specimens. One half of the stalk of the antennae of 

 the male is doubly feathered beneath ; the remainder to the 

 tip is bare. The antenna) of the female arc thread-like and 

 not fringed. The wings expand from one inch to one inch 

 and one eighth. The caterpillar figured by Mr. Abbot* is 

 oblong oval, striped with purple and yellow, with twelve lleshy 

 horns, of an orange color, on the sides of its back, namely six 

 on the fore part, two on the middle, and four on the hind part 

 of the body. Mr. Abbot says that it eats the leaves of the 

 dogwood {Cornus Florida), oak, and of other trees; that it 

 makes its cocoon in September, and that the moth comes out 

 in July. 



A still more extraordinary slug-caterpillar, having a very 

 remote resemblance to the last, has been found here on forest- 

 trees, and occasionally in considerable numbers on cherry-trees 

 and apple-trees, from July to September. It is of a dark brown 

 color, and is covered with a short velvet-like down; its body is 

 almost oblong square, but the sides of the rings extend hori- 

 zontally in the form of flattened teeth ; three of these teeth on 

 each side, that i^, one on the fore part, the middle, and the 

 hind part of the body, are much longer than the others, and 

 are curved backwards at the end. When fully grown, the 

 caterpillar measures nearly an inch in length. It does not 

 bear confinement well, and often dies before completing its 

 transformations. Dr. Melsheimer, to whom I am indebted for 

 one of the moths, informs me that the caterpillar eats the leaves 

 of the wild cherry, as well as those of the white and red oak, 

 that it makes its cocoon about the middle of September, 

 changes to a chrysalis the following April, and that the moth 

 appears in about eight weeks afterwards. The name given to 

 this insect by Sir J. E. Smith f is pithecium, the meaning of
