dots. The spiracles were reddish-brown, and over 

 each (except the first and last) was a small dot of the 

 same colour, which is not found on the other larva. 

 The claws were brown, and upon the yellow shining 

 head was, between the eyes, a brownish spot. 



The only variation in coloration I have noticed was 

 in some specimens which had the green of a bluish 

 tinge. As with the other species, the young larvae are 

 dusted all over with a white powder. 



Seemingly not very common in England and Scot- 

 land, but is widely distributed. 



Continental distribution : Sweden, Germany, France. 



America : Vancouver's Island and the Rocky Moun- 

 tains (Kirby, List of Hymen., i, p. 10).

Black ; tibiae and tarsi reddish-yellow ; wings yellowish, the apical 

 margin fuscous. The hair on the face and sides of the head black, on 

 the vertex yellowish. The hair on the thorax and base of the abdomen 

 also yellowish, more rarely greyish ; on the middle of the abdomen it 

 is fuscous or black; on the apical three segments it is yellowish or 

 yellowish-grey, and it is much longer than at the base or middle. The 

 femora are violaceous and clothed with black hairs. The antennae are 

 shorter than in the other species. 



The has the apex of the abdomen reddish. 



Length 6 8 lines. 



The black hair on the violet-coloured femora easily 

 separates this rare species from vitellinae. It is also 

 much smaller, and the hair on the abdomen is diffe-
