NEMATUS MILIARIS. 125 



is thus not transverse ; the black on the vertex, too, 

 is broader, but behind it is not quite so broad, the 

 edges being testaceous. 



The larva feeds on Salix caprea in August and 

 September, eating either along the edge or in the 

 centre of the leaf. Its head is green, with a faint 

 yellowish tinge ; there is a brownish stripe on either 

 side going down from the vertex to the eyes ; another 

 goes down the centre of face to its middle, the top is 

 mottled with light brown dots. Body deep green ; 

 legs glassy green, the skin is much wrinkled, and at 

 the sides the wrinkles form oblong raised objects, 

 which are edged with black. Over the eye is a black 

 line. The entire body is covered with black irregular 

 lines, which give the skin a m6ttled appearance, the 

 back being also more or less covered with these lines ; 

 the centre, however, being much lighter in tint. 



The single cocoon is spun in the earth, the flies 

 emerging in the following summer. 



The larva of N. miliaris is readily known from this by 

 its body not being mottled with black, and by its having 

 a distinct black lateral longitudinal line.
