184 Eev. T. A. Marshall's monograph of 



regions to the Mediterranean ; the Eev. A. E. Eaton 

 brought a specimen from Spitzbergen, and others were 

 sent to me from Italy by Dr. Magretti. According to 

 Eatzeburg both sexes were bred in April from galls of 

 Nematiis viminalis, L., on willows, by Hartig ; also by 

 Brischke from (probably) Nematus septentrionalis, L. ; it 

 is also mentioned as a parasite of Nematus frigidus, 

 Boh., and Nematus salicis, L. I have several times 

 taken it in England on umbellate flowers, and at Nunton 

 a specimen occurred belonging to var. 1.

 between the antennae, the front thus almost disappearing ; the 2d 

 cubital areolet is much smaller, contracted above ; the radius of 

 the hind wings distinct, &c., as already pointed out. The insect is 

 much larger, with blackish wings and orange-coloured abdomen, 

 Hke a Br aeon, for one of which genus it was formerly mistaken.
