The succeeding observations are chiefly touching the position of 
species in the various genera: as regards these I need merely remark 
that, as I have tested the characters offered by neuration and leg-spines, 
and find little or no variation, even between such remote groups as 
Goniurus and Achlyodes, I have preferred to follow out the more 
reliable characters offered by the palpi and antenne, which certainly 
separate the Hesperide into very natural looking genera; as to Hesperia 
Aunus, Fabr., being a “ Lycenine,” an examination of the type in the 
Banksian cabinet would convince Dr. Herrich-Schaffer himself that it 
was identical with Hiibner’s “ Nas,” which is certainly a Groniurus. 
The new genera founded in my paper must stand or fall upon their 
own merits: up to the present time I have been daily more convinced 
that they are natural and well-defined.

the sun. The interstice between the two marginal striz of the elytra — 
is a little narrower than the rest.
