404 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



iu this completes its transfoimatious. After reinaiuiug iu 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 streaks of pale brown appearing under a mag- 

 nifying lens as a fine network ; a dark brown, nearly black, stripe on each side, and 

 a few 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 chiefly 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 Gueu6e. 



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 iu the woods of northern Maiue 

 in August, and it is common iu August iu 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 unbroken, 

 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 wrinkled and folded. (Saunders.) 



The moth is exceedingly pretty and may be recognized by its white body and wings 

 and four deep golden -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 transversata 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™™. Changes to a pupa the end of July in a rolled leaf, the moth 

 appearing August 10. (Goodell.)
