Head and face metallic, dark fuscous. Palpi whitish. Antennae 

 dark fuscous, the extreme tips whitish. Anterior wings bright orange, 

 with an oblong silvery spot at the base near the costa, and with a 

 silvery slightly angulated fascia before the middle, internally margined 

 with black ; on the costa arc three equidistant silvery spots, graiUially 

 diminishing in size, and nearly opposite the second is a larger silvery 

 spot on the inner margin ; along the inner margin and costa, between 

 the spots, are some black scales ; cilia fuscous, preceded by a lew silvery

Head smooth, the forehead obtuse. Antenncie longer than the ab- 

 domen, setaceous, rather thick, the basal joint elongate, clavate. 

 Labial palpi of moderate hiuglh, recurved, the second joint com- 

 pressed, subclavate, the third joint shorter, pointed. Tongue of mo- 

 derate length. "Wings with very long cilia, the anterior smoolU, with 

 no projections from tlie inner margin ; the posterior linear-lanceolate. 

 In the anterior wings the apical vein is furcate, below it live veins run 

 into the hinder margin ; the subdorsal vein has a long fork towards the 

 l)ase, its apex is not far distant from the thickened apex of the sub- 

 median v(!in ; in the posterior wings live rather obsolete veins proceed 

 from the discoidal cell to the hinder nuu'gin, one to the costa. 



This genus at present only contains a single species, which 

 is extremely scarce in this country, and consecjuently we know
