NOTES. 



A. rossii, Pz. The Dale Collection at Oxford contains a S of tliis species 

 called "tenulus" (sic!) and a female called "viduus." {Viduus, Rossi, is a 

 synonym of bifasciatus, Miill. It is a South European species, with much 

 darker wings than those of rossii and the tibiae of the hind legs only yellow.) 



A. fiavipes, Fourcr. I have a ^ from the Oxford district, and a ? 

 from Colchester (Harwood). 



A. schacfferi, Kl. I have seen the specimens referred by Mr. Cameron to 

 this species, but they are certainly examples of marginellus. Their ventral 

 segments are black in both sexes, whereas in schacfferi ^ the venter is entirely 

 yellow, and in the ? it is banded with that colour. 



A. marginellus, Kl. According to Mr. Cameron's Vol. IV, the marginellus 

 of his Vol. II is really omissus. I possess British specimens {S S and ? ? ) of 

 both these species. Marginellus has been taken by Mr. G. Arnold in the New 

 Forest, and also by the late Mr. RoUason near Truro ; omissus by the late 

 Mr. McLachlan (Blackheath) and by Dr. Capron (? Shiere, Siu-rey). 



A. zona, Kl. This is the quadricinctus of Cam., Vol. II. I have only 

 foreign (Swiss) specimens myself, which are all ? ? . The J was unknoAvn to 

 Klug, and apparently also to Thomson, Cameron, and Andi'c. No author whom 

 I have consulted describes it! 



A. distinguendus, v. Stein. I have a ? taken by myself at Virginia Water,
