minute brownish dots, and there is on each side a 

 longish brown mark in which are the eyes ; another 

 brown line is on the centre of the forehead ; all these 

 marks are frequently united, so that the head becomes 

 of a brown colour, the mouth is deep brown. A few 

 hairs are scattered over the surface of the head. Legs 

 yellowish-green, the claws brown. The body is dark 

 greyish, or whitish-green, with a faint white line along 

 the sides, and marked also with some darker green 

 spots. 



When young the larva wants the white stripe, which 

 likewise disappears when the creature is ready for 

 pupating. 



I find the larvae early in July feeding on the leaf 

 buds of Salix repens, and more rarely on 8. aurita and 

 vitellina. When the leaves reach maturity the larvae 

 feed along the edges. The cocoon is spun in the 

 earth ; it is single, elliptical, brown, and thin. Accord- 

 ing to the observations of Brischke the larvae are found 

 from June to September, but in Scotland I have never 

 seen them after the end of July or beginning of 

 August. There is but one generation in the year. 



The only British localities I know of are Strath 

 Carron Ross-shire, Fossil Marsh near Glasgow, Wor- 

 cester, Exeter (Parfitt), London district (Billups). 



Also it is found in Lapland, Finland, Scandinavia, 

 Germany, Russia, Holland, France, Switzerland, and 

 the North of Italy.
