209. Opostega adusta, sp. n. 



Antennae with a broad shining white eyecap on the basal joint ; 

 beyond pale fawn -brownish. Palpi pale fawn-brownish. Head 

 and thorax shining white. Fore tvings shining white, with blue 

 and lilac reflections : a conspicuous umber-brown dorsal spot 

 at about one-third from the base ; a narrow dark umber-brown 

 shade along the costa a little beyond the middle is continued 

 to the commencement of the costal cilia ; a slender fuscous line 

 beginning in these runs obliquely outwards through the cilia 

 forming an angle at the apex of the wing, thence deflected along 

 the termen ; this is reduplicated by a slight shade in the middle of 

 the fawn-brown cilia beyond it, its upper half preceded by a slight, 

 ferruginous tinge running parallel with it from costa to apex; cilia 

 shining pale fawn-brownish along the dorsum and tornus. Under- 

 side spotless. Exp. al. 5 mm. Hind ivings and cilia pale fawn- 

 brownish. Abdomen (somewhat denuded) shining pale brownish. 

 Hind legs shining pale brownish ochreous, the bristles continued to 

 the tarsal joint. 



Type, S Mus. Hedemann. 



Hab. West Indies — St. Thomas, 20 III. {Hedemann). Unique. 



210. Opostega venticola, sp. n. 



Antenna* golden yellow ; eyecaps shining white. Palpi white. 

 Head and thorax shining white. Fore wings shining white, with two 

 minute oblique fuscous costal streaklets followed by a short straight 

 one before the apex, all tending to converge in the direction of a 

 single black point in the apical cilia ; the space between the first 

 and second streak is golden yellow, which extends also to the black 

 point but not to the dorsum or tornus ; a very narrow faint golden 

 spot rests on the middle of the dorsum : beyond the black point a 

 slight shade is visible in the cilia, which are otherwise white with 

 a golden tinge. Exp. al. 6 mm. Hind wings whitish grey; cilia 

 golden white. Abdomen white with a golden tinge. Legs : hind 

 tibias and basal joints of the tarsi with stiff hairs ; whitish 

 ochreous. 



Type, ($ Mus. Wlsm. 



Hab. West Indies — Hatti (Port-au-Prince, 23 V., Gudmann) ; 

 Grenada (Balthazar, 250-300 ft., windward side, 5IV.-8V.— 

 H. H. Smith). Four specimens. 



211. Opostega saltatrix, sp. n. 



Antenna 1 with a conspicuous shining white eyecap ; remaining 

 joints pale straw. Palpi small, slender, dependent; yellowish. 

 Head and thorax shining white. Fore wings shining white, with a 

 dark olive-grey fascia before the middle, diffused outwards at its 

 upper end to the middle of the costa ; this is followed by a streak 

 of the same colour, along the apical portion of the costa, reaching to 

 the apex ; a slender streak above it running through the cilia and 

 meeting it beyond the apex, this streak is sometimes very incon- 

 spicuoi's ; cilia pale olive-grey. Eup.al. 5 mm. Hind wings very
