Show 88 ME. E. Y. WATSON ON THE HESPEEIID7E. [Jan. 17, less conspicuous, being hardly visible on the upperside, but appearing below as a pale oval streak. This inconspicuous nature of the male mark in fuscula would doubtless account for its being overlooked by Heer Snellen, especially if the specimens he examined were at all worn. This species can be separated from pulligo by having the underside of the hind wing entirely unmarked, and by the beautiful plum-like bloom of the upperside. This last character is only apparent in fresh specimens, those in the Hewitson collection in the British Museum having faded to a dull brown. Fuscula seems to be confined to Celebes, while pulligo ranges from Assam throughout Burma, Malacca, Java, Borneo, Sulu, and Palawan, and also occurs in Southern India. 30. Genus EUMESIA. Eumesia, Felder, Reise Novara, p. 504 (1867). Type, semiargentea, Feld. Antennse short, less than half the length of costa; club stout, arcuate, tip acuminate. Palpi porrect ; third joint very slender, bluntly pointed. Fore wing: inner margin considerably longer than outer margin; cell less than two-thirds the length of costa ; vein 12 reaching costa almost opposite the end of cell; vein 5 slightly nearer to 4 than to 6; vein 3 well before end of cell, much curved in its course; vein 3 slightly nearer to base of wing than to end of cell. Hind wing : outer margin evenly rounded ; vein 7 shortly before end of cell; discocellulars and vein 5 barely traceable ; vein 3 immediately before end of cell; vein 3 nearer to end of cell than to base of wing.

Genus ARGOPTERON, nov. Type, aureipennis, Blanch. Antennse more than half the length of costa; club moderate, straight, elongate, tip blunt.
