The genus A; /Hades, as we understand it, consists of a very few 

 closely-allied species, of which thetis (bellargus) and coridon are the best- 

 known. They are recognised almost at sight by their general appearance 

 as well as, usually, by the strongly-chequered, black and white, fringes; 

 the ? s particularly are similar, and, according to some lepidopterists, 

 are sometimes difficult to distinguish, the similarity extending to the 

 ground colour and spotting of the underside, but we find it hard to 

 believe that any careful student need be troubled by this similarity. 

 The genus Agriades, as originally described by Hiibner (Verz., pp. 

 67-68), was a most heterotypical group, his description reading as 

 follows : — 



The wings entirely bright blue, the underside adorned with red marginal spots —

The species here enumerated comprise, practically, representatives of 

 the greater part of the genera comprised in our tribe Plebeiidi (antea, p. 

 154-157), but, in addition, also the Celastrinids (Celastrina argiolus), 

 whilst jmnoptes belongs to Hiibner's next group (Scolitantides), which he 

 evidently failed to recognise in hylas, Schiff. (amphion, Esp.), a synonym 

 of the same species which he rightly places. In 1835, Stephens, in the 

 appendix to Illus. Brit. Ent. Haust., iv., p. 404, uses the name for argiolus, 

 corydon, dorylas, adonis, aleccis, agestis, and icarius; whilst, in 1850, he 

 further restricts it {Cat. Br. Lep., p. 19) to corydon, adonis, and alexis, this 

 time excluding argiolus and agestis. In 1858, Kirby, in his List of Brit.
