dissected (and photographed) one or more examples of each of the species for figuring. 

 Watson adopted ninety-eight genera of this subfamily (leaving twenty-six unidentified), 

 though only one new genus was proposed by him for American forms, to include about 

 384 species. An equally large number are required for the Central- American species, 

 about 240 of which are known to us, very many of them being isolated forms. The 

 genera here enumerated include altogether about 100 species in addition to those 

 occurring within our limits. As Watson referred nearly the whole of the American 

 Pamphilinse to one group, B, his scheme of arrangement of the genera will not help us 

 much, though we have followed him in placing the species with short antennee first, 

 the largest and most conspicuous forms, most of which have very long antenna?, thus 

 coming last. We have, for convenience, arranged the Central-American Pamphilina3 

 into eight groups, based chiefly on the structure of the antennae and palpi ; but it must 

 be observed that they are of very unequal extent, and that groups VI.- VIII., which 

 include by far the greater number of species, are connected by intermediate forms. 



I. Antennae with an arcuate, gradually acuminate club ; terminal joint of the palpi moderately 



long, porrect ; primaries of the male without a brand. 

 This group includes Butleria and Pamphila, the first mentioned having two pairs of spurs to the 

 hmd tibiae, the latter a single pair only. It corresponds, as regards the American genera, to 

 Watson's section A, less Amblyscirtes , which belongs to our group VI. 



II. Antennae very short, with a straight, or slightly curved, blunt club ; terminal joint of the palpi 



long and erect; hind tibiae with two pairs of spurs. 

 This group includes Apaustus, Oarisma, Adopaoides (type, Ancylowypha simplex, Feld.), Ancy- 

 loxypha, and Copaodes, the last-mentioned genus alone having a brand on the primaries in the male. 



III. Antennas very short, with a stout, slightly pointed club ; terminal joint of the palpi short ; 



primaries of the male branded ; hind tibiae with two pairs of spurs. 

 This group includes Cha-rephon (type, Pamphila citrus, Mab.), Hylephila, and Erynnis. 



IV. Antennae short, with a stout club, terminating in a short crook ; terminal joint of the palpi 



short ; hind tibiae with two pairs of spurs ; primaries of the male with a greatly developed 

 brand. 



This group includes Atalopedes, Thymelicus, Catia (type, Hesperia druryi, Latr.), Ochlodes, 

 and Augiades. 



V. Antennas short, with a rather slender club, terminating in a short crook ; terminal joint of the 



palpi short ; hind tibiae with a single pair of spurs ; primaries of the male without a brand. 

 This group includes a single genus only, Zariaspes (type, Urbanus mys, Hiibn.) . 



VI. Antennae short, with a stout or moderately stout club, terminating in a short crook ; terminal 



joint of the palpi short or moderately short*; hind tibiae with two pairs of spurs ; primaries 

 of the male with or without a brand, the latter, when present, moderately developed or 

 inconspicuous. 



Numerous genera belong here, as Phycanassa, Atrytone, Lerodea, Amblyscirtes, Stomyles, &c. 



Longer in some species of Stomyles.
