404 Firm REPORT OP the entomological commission. 
in this completes its transformations. Alter remaining in the pupa 
state about two weeks, the moth appears. (Saunders.) 
We have bred this moth in Maine from the caterpillar. The chrys- 
alis lay in a slight cocoon in a folded leaf of the red maple, the moth 
issuing in the second week in May. 
The larva is 1.40 inch long, somewhat onisciform. Head medium sized, flattened, 
bilobed; color, pale ashen gray, with Btreaka of pale brown appearing under a mag- 
nifying lens as a fine network ; a dark brown, nearly black, stripe on each side, and 
a Bbw short gray hairs scattered over its surface. Body above brownish-gray, with 
numerous streaks and dots of pale brown. A. double irregular dorsal line; other 
broken lines composed ohiefly of dots, none of them continuous, A subdorsal row of 
whitish dots. On the hinder part of the twelfth segment is a raised crescent-shaped 
line edged behind with black, and on the terminal one two whitish dots, with a small 
black patch at their base. Spiracles pale oval, edged with black. Under surface 
paler and greenish, feet greenish, prolegs bluish-green dotted with brown. The 
moth is rather large, with broad triangular fore-wings, and is uniformly brown, with 
two oblique darker bands. 
36. The lesser maple span-worm. 
Stegania pustularia Gnenee. 
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 five-eighths of an inch long, head medium 
sized, rather flat in front, slightly bilobed, pale green. Body above bluish-green, 
with thickly set longitudinal stripes of whitish and yellowish. A double whitish 
dorsal line, with bordering lines of yellowish white, neither of which are unbrokeu, 
but are formed of a succession 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 wriukled and folded. (Saunders.) 
The moth is exceedingly pretty aud may be recognized by its white body and wings 
and four deep goldeu-ocherous costal spots, with two lines running across the wings, 
these lines sometimes wanting. It expands an inch. 
37. The large maple span-worm. 
Eutrapela transversaia Packard. 
Feeding on the 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 red- 
dish ; a dorsal reddish-gray crescent-shaped spot on the middle of the seventh seg- 
ment, behind which is a pair of low kidney-shaped tubercles, and a pair of dorsal 
pointed black ones on the eleventh ; second ring swollen on the sides. Length, 
when crawling, 46 mm . Changes to a pupa the end of July in a rolled leaf, the moth 
appearing August 10. (Goodell.)
