The true Hyllus seems to me to be an Axiocerces, and its home probably 

 given correctly by Cramer.

Type: Polyommatus Epixanthe Boisd.-Le C. 



Almost all the smaller species of coppers fall into this genus, which includes 

 also the European Doriias and Ampliidamas. In the former of the two sec- 

 tions into which it is here divided, the basal joint of the middle and hind tarsi 

 are not at all swollen; in the latter section, which includes the European spe- 

 cies mentioned, they are swollen to a very slight degree; the species of the 

 first section also have the hind wings of the male more rounded than those of 

 the latter. In all the species the markings of the under surface of the hind 

 wings (which are usually very light) show a tendency to form an extra-mesial 

 series of sub-connected slender lunules, recalling, in £J. Marijwsa, the most 

 extreme case, their appearance in the species of Tharsalea. The antennal club 

 is rather shorter than usual. The fore tibiae of the male are longer than 

 usual, more than equaling the length of the fore tarsi.
