This species of Nbmada is the parasite of Panurgus banJcsianus, 



and is always to be found with colonies of that insect during the 

 months of June and July. Kirby suspected that his A. quadrinotata 

 was the male of this species ; but the insect was not found commonly 

 at Barham. At Hampstead it has occurred in great abundance. It 

 is local, but widely distributed ; it has been found at Bournemouth, 

 Tentnor (Isle of Wight), Sidmouth, in all the home counties, and in 

 Yorkshire.
