80 LOPHYRUS PINI. 



spiracles the sides are paler. Legs black, paler at the 

 junction of the joints, and there is an oblique white 

 band on either side of the basal joint. 



The coloration of the head is very variable ; some- 

 times it is entirely pale green, with the mouth parts 

 brownish; from that it varies through all shades of 

 brown to deep black. I have found a larva with the 

 body nearly entirely green, the black marks along the 

 sides being almost obsolete. 



In Scotland I find the larva mostly during July and 

 August, and sometimes in September. The flies appear 

 in June.
