LOPHYRUS DOESATUS. 75 



The larva is green, including the head. On the 

 latter a blackish or dark stripe runs from the vertex 

 into each eye, and the face may be more or less black ; 

 the mandibles are brownish, the skin is smooth and 

 shining, the sides are paler below the spiracles, and 

 along the middle runs a darker green stripe, there being 

 also a darker green stripe down the back. Under the 

 spiracles the skin folds are white. Legs green with 

 blackish claws ; the ventral legs are paler. 



According to Hartig the larvaa of virens are found 

 mostly during the last half of June in Germany, and 

 chiefly upon pines of from twenty to thirty years old. 

 The cocoon is spun in July, the flies appearing in May 

 and June of the following year. In Scotland I have 

 found the flies during the latter end of June. 



Parasites on the larvae are : Tachina bimacMlata, 

 Htg. ; Tryphon leucostictus, Rtz. ; T. scutellatus, Htg. ; 

 T. succinctus, Gr. ; T. transiens, Gr. T. scutellatus is 

 a parasite on the Tachina. 



Rare : Rannoch. 



Continental distribution : Sweden, Germany, France.
