? . Deep cliocolatc- or pitch-brown^ with the ordinary ocellus and other markings of 
A^. 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 submai'giual series ; the external area immediately beyond the 
second series suffused and ash-grey. Expanse of wings 98-103 millim.

Nyctipao glaucopis. (Plate CXII. fig. 4.) 
Nyctipao glaucopis, Wallcer, 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 partlj' parallel series of 
pale spots beyond the middle ; the first two or three of the inner series on the primaries and 
of the oiitcr 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

Ophiusa conficieris, Wallcer, Cat. Lep. Ilet. xiv. p. 1432. n. 29 (1S57). 
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
