112 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
habits are described by Harris, who says that it also feeds on the elm, 
linden, and chestnut. We have often noticed it in Maine. 
13. FOREST TENT CATERPILLAR. 
Clisiocampa sylvatica. 
A colony of the worms not fully fed were found June 6, collected in a 
mass near the ground on the trunk of the maple at riaewiee Me.; at 
this time they were molting for the last time. 
14, THE MAPLE SLUG MOTH. 
Lithacodes fasciola H. Sch. 
Order LEPIDOPTERA; family BOMBYCID2. 
According to Clemens, the larva is elliptical, somewhat pointed behind ; 
body thickest in the middle, flattened, with the sides curving from a 
central ridge; this Pies has a vertical elevation at its 
sides above the body, growing less and less before and 
behind, terminating in front in a rounded margin, and 
behind in an obtuse, short spine. The body is smooth, 
er 31-—Mayostug with no distinct spined papule, but the edges of the 
Pakeard. ridge and the outline of the body are thrown into sub- 
crenated folds. 
15. THE LESSER MAPLE SPAN-WORM. 
Stegania pustularia Guenée. 
Feeding on the leaves early in June, a bluish-green looper striped with whitish and 
yellowish, producing the moth in July. (Saunders. ) 
This is a common insect and has been raised by Mr. W. Saunders, who 
says that the caterpillar is full grown about the middle of June, enters 
the chrysalis state within a few days after, and produces the moth early 
in July. We have found it in the woods of Northern Maine in August, 
and it is common in August in the Northern and Western States. 
The larva,—Body cylindrical, about 2 inch long, head medium sized, rather flat in 
front, slightly bilobed, pale green. Body above bluish-green, with thickly set longi- 
tudinal stripes of whitish and yellowish. A double whitish dorsal line, with border- 
ing lines of yellowish white, neither of which are unbroken, but are formed of a suc- 
cession of short lines and dots. Below these, on each side, are two or three imperfect 
white lines, made up of short streaks, and much fainter than those bordering the 
dorsal line; spaces between the segments yellowish. The skin all over the body is 
much wrinkled and folded. (Saunders. ) 
The moth is exceedingly pretty and may be recognized by its white body and wings 
and four deep golden-ochreous costal spots, with two lines running across the wings, 
these lines sometimes wanting. It expands an inch. 
16. THE LARGE MAPLE SPAN-WORM. 
Lutrapela transversata Packard. 
Feeding on red maple in July, a large slender-bodied span-worm, the body thickened 
behind, carinated on the sides; of a dark purple-brown mixed with reddish; a dorsal
