Tenthredo flava (Vol. I, p. 74). 



The larva of this species is described and figured 

 by Brischke, p. 3, Taf. vii, fig. 9. It feeds on Mgopo- 

 dium podagraria. It is 22 mm. long, of a beautiful 

 bright reddish-brown colour, and has the dorsal vessel 

 bordered on either side by a brown longitudiual line. 

 At the base of each segment on either side of the 

 dorsal vessel is a brown line proceeding backwards 

 obliquely towards the feet. At the beginning of each 

 segment are two darker lines which form a pointed 

 angle, the apex of which is directed towards the legs, 

 the lines to it from the back being darker than those 

 from the feet to the back. The head is small, shortly 

 pilose ; the claws are brown. On each segment are two 

 transverse rows of white tubercles. When young the 

 ground colour is darker and greener. At the last 

 moult it becomes smooth and brighter in tint.
