106 PAMPHILIUS PALLIPES. 



and in the lateral lobes of mesonotum being marked 

 with white. I have a specimen from Kingussie. 



The larva is clear grass -green ; on the back is a 

 small darker line, and there is a yellowish lateral line. 

 The head is shining green with black eye-spots, and 

 with three black points on the vertex ; mouth brown. 

 On the upper part of the second segment are two small 

 black marks, and on the side are two longer ones. 

 Above each leg is a shining black mark. When young 

 the body has a more yellowish tinge, and the head and 

 second segment, as well as the anal lobe, are black. 



It lives in the folded-down leaves of the alder, the 

 edge of a leaf being rolled down into a tube, the roll 

 being kept together by means of silk threads. Inside 

 of this the larva lives, only coming out of it to feed. 

 The larvso feed during July, the flies appearing in May 

 and early in June. 



Common in Scotland, apparently rarer in England, 

 but still widely distributed. 



Continental distribution : Sweden, Germany, Russia, 

 Holland, France, Switzerland.
