5. ZEUXIDIA AMETHYSTUS. 
Upperside. Front wings deep brown glossed with purple ; a broad 
lilac band glossed with purple near the apex, extending from the 
anterior margin, just beyond the cell, to the third median nervule, 
wider above than below ; outer margin pale. Posterior wings, anal 
angle caudate ; wings rich brown, lower portion glossed with purple ; 
a broad lilac patch, glossed with purple, bisinuate on its inner edge, 
at the anal angle, extending from just below the body to the fold 
between the second and third median nervules; cell hirsute, hair 
ochreous ; outer margin pale. 
Underside. Front wings golden brown, dusky towards the inner 
margin ; a narrow, irregular, oblique, deeper-brown band crossing 
the middle of the wings; three irregular paler brown bands crossing 
the cell at equal distances ; a pale brown spot on the anterior margin, 
just beyond the central band; two similar spots near the apex. 
Posterior wings golden brown ; a deeper, oblique, narrow, irregular, 
brown band crossing the wings at the end of the cell, from near the 
end of the costal nervure to beyond the middle of the third median 
nervule ; two indistinct, pale brown, irregular bands near the base, 
the inner one extending to the median nervure, the outer one to the 
middle of the cell; a large, oval, ochreous ocellus, pupillated with 
white, between the first and second subcostal nervules, and a circular 
ochreous ocellus pupillated with white between the second and third 
median nervules. 
Hab, Sumatra. 
This species is the third of the genus, unless we include in it 4ma- 
thusia amythaon, Doubleday (Sylhet), which should, as I think, 
belong to it. The latter appears to be allied to my species, which, 
however, seems to be intermediate between Zeuzxidia luxeri, Hiibner 
(Java), and Zeuxidia doubledaii, Westwood (India), though evi- 
dently quite distinct from both of them. 
6. HeTEROCHROA CALIFORNICA. 
Upperside. Front wings deep brown, crossed beyond the middle 
by an irregular band of cream-coloured spots ; hind margin pale ; 
two short orange transverse bands margined with black, the one 
crossing the middle, the other the end of the cell, between them a 
short black band; a large subapical orange blotch ; a lunulate pale 
brown submarginal band, extending from the subapical blotch to the 
anal angle; cell blue-grey. Posterior wings dee) brown, crossed 
before the middle by a cream-coloured band tapering to just above 
the anal angle, slightly trisinuate on its outer edge, its inner edge 
slightly undulating ; outer margin pale, a lunulate submarginal pale 
brown band ; an orange lunule at the anal angle. 
Underside. Front wings, apical half deep brown; cell pale blue, 
interrupted as above; front margin pale ochreous; beneath the cell 
pale brown; a pale orange spot below the median nervure near its 
origin, angulated on its outer edge ; cream-coloured band as above ; 
subapical blotch extending to the middle of the wing, bordered by
