Hah. Nicaeagua, Chontales (Belt, Janson); Panama, Chiriqui (Bible, in mus. 

 Staudinger), Veraguas (Arce). — Amazons Valley; Guiana. 



We have as yet only seen female specimens of this species ; but we have a male from 

 Colombia which we refer to Phareas priscus, Feld., and this has a costal fold to the 

 primaries. 



Whether these two forms are really distinct is questionable, our materials are not 

 sufficient to determine the point. The few Central- American specimens we have seen 

 agree closely with others from Guiana and the Amazons Valley, and also with Clerck's 

 figure, which represents the Linnean type. 



PHANUS. 



Phanus, Hubner, Verz. bek. Schm. p. 114 (1816) ; Wats. P. Z. S. 1893, p. 40. 



The single species contained in this genus is not liable to be confused with any other, 

 the wings, both primaries and secondaries, having diaphanous marks far exceeding in 

 size and number those of any other Hesperid. 



The antennae have a short club curved before the middle into a strong hook, tapering 

 to a fine point. Palpi with a short but distinct terminal joint, divergent as in the 

 preceding genera. The primaries have a gradually arched costa, the outer margin 

 convex, nearly straight towards the anal angle, which is acute ; the cell is long, quite 

 three-quarters the length of the wing; the upper discocellular distinct, middle and 

 lower discocellulars subequal in a slightly oblique line to the axis of the wing ; third 

 median segment short, not more than half the second segment ; discocellulars of the 

 secondaries very feeble, the lower meeting the median at the origin of the second 

 branch, so that there is no third median segment, second median short, but longer 

 than the second subcostal segment. Hind tibiae with two pairs of spurs and a dorsal 

 crest of hairs. Primaries of the male with a costal fold. 



The type species ranges over the greater part of Tropical America, from the Mexican 

 State of Vera Cruz to South-eastern Brazil.
