LEPIDOPTERA

resembles the canker-worms in many particulars. The larva is a looper 

 which infests both fruit and forest-trees; and in the adult state the male 

 has well-developed wings, while the female is wingless. 



The eggs are oval, of a pale yellow color, and covered with a network 

 of raised lines. They are thrust by the female under loose bark and in 

 crevices on the trunk and large limbs. They hatch in May, and the 

 larva? attain their full growth in the latter part of June. The larva is 

 yellow, marked with ten crinkled black lines along the top of the back; 

 the head is rust-colored, and the venter yellowish-white. There is a 

 second form of the larva which is brown above with slate color towards 

 the sides. When full-grown the larva measures about i-J inches in length. 

 The pupa state is passed in the ground. The moths issue in October or 

 November; and then the wingless females ascend the trees to oviposit as 

 do the females of the canker-worms. The female is represented in the 

 lower left-hand part of the figure. She is grayish in color, with two black 

 spots on the back of each segment except the last, which has only one. 

 The male has pale yellow and brown or buff fore wings, with a central 

 spot and a band beyond the middle, while the hind wings are much 

 lighter. ^ 



The notched- wing geometer, Ennomos magnarius. — This is one of 

 the larger of our geometrids. The larva is a common looper upon maple, 

 chestnut, and birch trees, and measures about 2 \ inches in length when 

 full-grown. It spins a rather dense, spindle-shaped cocoon within a 

 cluster of leaves. The moth (Fig. 395) is ochre-yellow with reddish 

 tinge. The wings are shaded towards the outer margin with brown, and 

 are thickly spotted with small brown dots. The polished greenish-brown 

 to bronze colored eggs are laid side by side in a long linear row on the 

 branches of apple, pear, lilac, and chestnut.

The pepper-and-salt currant-moth, Amphidasis cognataria. — This 

 moth (Fig. 396) differs remarkably in appearance from most geometrids, 

 the body being stouter, and the wings appearing heavier. It can be 

 easily recognized by its evenly distributed pepper-and-salt markings. 

 The larva feeds on various plants, but is found most often on currant. 



Family Notodontid^; 



The Prominents 



This family includes moths of moderate size, only a few of the larger 

 ones expanding more than 2 inches. The body is rather stout and 

 densely clothed with hair, and the legs, especially the femora, are clothed 

 with long hairs. The wings are strong, and not very broad, the anal
