‘This species is considerably larger than that from Java, and, 
curiously enough, the colouring of the sexes is reversed, the 
male of the Amboinese species having the basal three fifths of 
the primaries white clouded with grey at the base, and the 
female with a narrow angulated white band, nearly as in G. 
leos. 
30. Gerydus stygianus, sp. n. 
Allied to G. learchus; above fuliginous brown with bronze 
reflections; a whitish fusiform spot at base of third median 
branch: wings below greyer than in Felder’s figure of G. 
learchus, with a faint lilac tint, the markings rather narrower 
and the band across the disk of primaries uninterrupted. HEx- 
panse of wings 37 millim. 
Ternate. 
Unfortunately only one somewhat damaged example was 
obtained of this interesting species.

32. Catochrysops trifracta, sp. nov. 
g. Deep lilac, the thorax above blue-black ; head white ; 
palpi with the terminal joint and a dorsal line black ; abdo- 
men blackish grey: wings below much as in C. engjus, but 
differing noticeably in the fact that the series of spots across 
the disk of the primaries, instead of forming one slightly irre- 
gular stripe, are broken into three parallel oblique bifid white- 
edged brown dashes, one below the other; the secondaries 
also have only one subanal black spot with pale yellow zone,
