? . Deep chocolate- or pitch-brown, with the ordinary ocellus and other markings of 

 N. caprimulgus, but the pale irregular discal line bounding the external area replaced by a 

 similarly formed but much wider snow-white band, which in some examples is widened on the 

 secondaries to a broad belt and encloses a few smoky brownish spots : on the under surface it 

 differs in the great size and snow-white colour of the spots across the disk of the wings, and 

 the greater proximity of the series of small spots to the discal series, thus rendering them a 

 second discal instead of a submarginal series ; the external area immediately beyond the 

 second series suffused and ash-grey. Expanse of wings 08-103 millim.

Nyctipao glaucopis. (Plate CXII. fig. 4.) 

 Nyctipao glaucopis, Walker, Cat. Lep. Het. xiv. p. 1306. n. 6 (1857). 



Smoky olive-brown shot with purple ; the ordinary ocellus rather large, with the iris a 

 little broader than usual ; ordinary lines wanting ; indications of two partly parallel series of 

 pale spots beyond the middle ; the first two or three of the inner series on the primaries and 

 of the outer series on the secondaries white. Under surface olive -brown, shot with purple ; 

 the wings crossed beyond the middle by a series of snow-white spots, the first five of the 

 primaries and the first two on the secondaries considerably broader than the others. Expanse 

 of wings 109 millim.

 Ophiusa conficiens, Walker, Cat. Lep. Het. xiv. p. 1432. n. 29 (1857). 



Primaries above dark chocolate-brown, crossed obliquely from the costa before the middle 

 to the inner margin by a nearly straight white band and from the costa at apical fourth to 

 the inner margin near the external angle by a slender tremulous angulated and sinuous 

 creamy yellowish line ; external border creamy yellowish, the margin indicated by a slender
