therefore, with the entire structure of the imago, removes it from the Diurnal Lepidoptera, 

 and associates it most satisfactorily with the Hesperi-sphinges of Latrielle, especially 

 Agarista and Coronis, which last is very near Urania Lunus. Thus the situation proposed 

 for these insects by LatreiUe, between Hesperia and Agarista, &c. is found to be most 

 fortunate ; Mr. Swainson himself admitting a relationship with the Hesperiidae, by calling 

 them the " Hesperian " t}'pe of the Papilionidse. They also appear to have some relation 

 with Erebus. The original specimen here figured is stated by Mr. Drury to have been in 

 the possession of Captain May, of Hammersmith, when the drawing was made. It is now 

 in all probability destroyed, and cannot be traced.

Fabricius, without referring to this figure of Drury, described an Indian species of the 

 same genus from Drury's collection, under the same specific name, which must of course 

 be rejected. The French encyclopedists consider the latter as identical with the Fabrician 

 Hesperia Isocrates.
