TENTHREDO SOLITARTA. 79 



September and October on Circcea lutetiana and on the 

 fuchsia. It feeds generally in the evening, devouring 

 the leaves, flower and fruit. The head is honey- 

 yellow, shortly and thinly pubescent, with a black spot 

 on the vertex, this spot being generally divided in 

 two. The body is pale brownish-yellow, marked above 

 with darker brown lines, proceeding from the centre 

 of the back to the sides in the direction of the tail, 

 there being also a dorsal line of the same colour. 

 The sides and legs are dirty white. On the second 

 segment is, on each side, a blackish mark. The whole 

 body is covered with numerous pointed, clear tubercles, 

 each ending in a hair. The cocoon is spun in the 

 earth, the imago making its appearance in May and 

 June. 



It does not seem to be a common species in Britain. 

 Dr. Sharp has taken it in Scotland, at Thornhill, and 

 Stephens records it from the London district. 



Its European distribution is wide, being found in 

 Sweden, Germany, Holland, Italy, Hungary, and 

 Russia (Casan district).
