permanent and the tarsi in some Chrysophanus are quite as feebly spined : 
as they are in Lycaena. 
Thecla is generally easily distinguished by the form of the wings, 
which however often approaches some species of /ycaena——especially 
those of the Chrysophanus group. In the latter there are variations of 
wing form without number but asa whole the primaries are narrower 
and longer, and the secondaries have the costal instead of the internal 
margin longest. éenesica is in wing form somewhat different from the 
- others of the family and the marking is unique. Mr. Scudder in Buf. 
Bul. II] 98 et seq divides this family into 33 genera ! ! ! 
The next and last family is the Aesperidae, numerous in species, which 
are Closely allied ; their fascies is peculiar and they can be readily enough 
recognized by the characters given in the table of families. 
The genera are as follows.
