 Panama, Bugaba (Champion), Chiriqui (Trotsch, in mus. Staudinger). — Colombia. 



Dr. Staudinger has lent us for examination three examples of this very distinct 

 species — a pair from Chiriqui and a male from farther south ; Mr. Champion obtained 

 two specimens of it at Bugaba ; and we have two males from Honduras. 



This insect is very like Rhinthon epaphus, but the absence of the brand on the 

 primaries of the male, the longer crook to the antennae, and the yellow border to the 

 anal angle of the secondaries sufficiently distinguish it. The yellow coloration varies 

 in extent, being reduced to a narrow marginal line in the single male from Corosal ; 

 but in the females it is always greatly extended. T. xanthura will probably have 

 to be removed from the genus Thracides, but for the present it can remain here. 

 For the genitalia of the male, see Tab. CVI. fig. 13. 



PERICHARES. 



Perichares, Scudder, Rep. Peabody Ac. Sci. iv. p. 81 (1872); Watson, P. Z. S. 1893, p. 122. 



The type of this genus is Papilio coridon, Fabr., and it includes Telegonus lotus, 

 Butl., and various other Tropical- American species. Perichares is very closely allied 

 to Talides, but has more produced primaries, a longer cell, and the third median 

 segment is nearly half the length of the second. In both genera there is a conspicuous 

 oblique brand on the primaries of the male. In P. lotus the hyaline spots on the 

 primaries are different in number and position in the two sexes. 



The antennae are very long, nearly reaching the end of the cell, and have an elongate 

 club terminating in a long crook. The palpi are densely clothed with scales ; the third 

 joint is almost entirely concealed. The primaries are elongate and rather pointed ; the 

 cell is two-thirds the length of the costa ; the disco cellulars are almost in*a line with 

 the third median segment and very oblique, the upper one more than twice the length 

 of the lower; the lower radial is strongly depressed at the base; the first branch 

 arises considerably before the middle of the median nervure, the second a long way 

 before the lower angle of the cell ; the third median segment is twice the length of 

 the lower discocellular, and nearly half that of the second segment. The secondaries 

 are produced at the anal angle ; the discocellulars are very oblique, the lower one
