BUTLEEIA. 463 



In certain species of Atrytone and Paratrytone the costa of the secondaries is clothed at the base 

 with long projecting hairs, which have somewhat the appearance of a frenulum. 



VII. Antennae moderately long * with a long crook ; hind tibiae with two pairs of spurs ; primaries 



of the male with or without a brand. 

 This group includes the great majority of the American Pamphilinse. For convenience, it may be 

 divided into two sections : (A) Terminal joint of the palpi short or moderately short; (B) Terminal 

 joint of the palpi long and erect, quite slender in some of the genera, stouter in others. Section A 

 includes Calpodes, Prenes, Aides, Niconiades, Cobalus, Phemiades, Lerema, Phlebodes, Padraona, 

 Carystus, Coeliades, and many others ; section B, Cymcenes, Callimormus, &c. In some of the 

 genera of this group the discocellulars of the primaries are subequal in length, as in Butleria,, 

 Pamphila, &c. 



VIII. Antennae very long f, usually at least two-thirds the length of the costa, with an elongate 

 club, terminating in a very long crook ; terminal joint of the palpi short (except in Falga) ; 

 primaries of the male with or without a brand. 



This group includes a variety of forms, some with slender bodies, as Falga and Enosis, others 

 with a robust body, as Thracides, Talides, Perichares, &c. The hind tibiae have two pairs of spurs, 

 except in the genus Carystoides (type, Hesperia basochesi, Latr.) , which has one pair only. In one 

 genus, Orses (type, Hesperia cynisca, Swains.), the neuration of the primaries, as well as the system 

 of coloration, is different in the two sexes. The largest and most conspicuous representatives of 

 the Tropical- American Pamphilinse belong here ; some of them closely resemble various species 

 of the subfamily Pyrrhopyginae. 



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

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



A. Posterior tibiae with two pairs of spurs. 



BUTLERIA. 

 Butleria, Kirby, Syn. Cat. Diurn. Lep. p. 624 (1871); Watson, P. Z. S. 1893, p. 79. 



Watson includes numerous American species under Butleria, and gives B. valdivianus 

 (Phil.) as the type. Amongst these there is considerable variation in the length of 

 the terminal joint of the palpi, which is long in B. valdivianus, and short and stout in 

 B. epiphaneus, Feld., but between these there are intermediate forms. 



The antennae are rather short, and have a moderately stout, arcuate, acuminate club. 

 The primaries have the costa arched at the base and then straight to the apex ; the cell 

 is a little less than two-thirds the length of the costa ; the discocellulars are equal in 

 length and transverse ; the lower radial is straight ; the first branch arises before the 

 middle of the median nervure, the second close to the lower angle of the cell, the latter 

 being somewhat curved outward. The secondaries are rounded at the anal angle ; the 

 cell is broad and more than half the length of the wing ; the discocellulars are transverse 



* Short in some species of Prenes, and very long in Thargella, Coeliades, and certain species of RMnthon 

 (type, Proteides chiriquensis, Mab.). 



t Shorter in Pyrrhopygopsis (type, Pyrrhopyga socrates, Men.).
