has a slender, median, brown stripe; (lie sides have two dingy-white stripes, 

 the upper straight, the lower undulating; the spiracles are placed below the 

 second white si ripe, and are intensely black ; the belly has six whitish stripes, 

 of \\ Inch the median ones are closely approximate. The divisions of (he seg- 

 ments are marked by slender rings of a pink tinge. It feeds on birch and 

 sallow, and is full-fed at the end of May, when it spins a lew threads, and 

 draws together the leaves of its food plant, making a very open kind of net- 

 work cocoon, so open, indeed, as not in any degree to hide the enclosed 

 chrysalis, which will even drop out through the meshes if shaken. The 

 chrysalis is rather long, and very pointed at the tail; it is of pale putty-color, 

 willi a broad, conspicuous, median, brown stripe down the thorax and body; 

 the oblique posterior margins of the thorax are also of the same dark color; 

 the head and wing-cases are dingy-brown, lined with darker brown, by which 

 color the antennas, legs, wing-rays, &c., are clearly indicated ; the antenna? 

 case slightly exceeds that of the wings in length. On the body is a median 

 dark stripe below, corresponding with that above, and the lateral region 

 between these two stripes is spotted with dark-brown." — Newman's British
