towards the base ; an arched brown band from the costal border 
beyond the cell to the outer margin near external angle; 
apical area cream-colour; fringe dark brown: secondaries 
cream-colour. Expanse of wings 45 millim. 
Duke-of- York Island. 
28. Appias delicata, sp. n. 
3. Allied to A. celestina. Pale chalky blue, with the veins 
on external area of primaries and a tapering external border 
black : secondaries with the second subcostal, radial, and third 
median veins terminating in diffused black spots; abdominal 
border whitish: body blue-grey. Under surface bluish 
white ; primaries with a blackish squamose streak from the 
fifth subcostal or upper radial branch to the external angle, 
“uniting upon the veins with a tapering internally sinuated 
marginal grey band : secondaries with the basal half of costal 
area bright sulphur-yellow; discoidal cell and disk creamy 
yellowish, shading off externally into a submarginal diffused 
greyish band united on the veins to a grey border, so as. to 
leave four or five large spots of the ground-colour; base of 
abdominal border and pectus pale sulphur-yellow. Expanse 
of wings 73 millim.

29. Belenois picata, sp. n. 
3 ?. Allied to B. tewtonia of Australia, but differing on 
both surfaces in the much larger submarginal white spots, 
and on the under surface in the total absence of all the orange 
patches and spots. Hxpanse of wings 64 millim. 
New Britain. 
As Donovan gives perfectly recognizable figures of B. teu- 
tonta (omitting only the small black discocellular line on the 
male) it is unnecessary to describe B. picata in full. 
30. Zetides seminigra, sp. n. 
Differs from 4. agamemnon above in the greater size of the 
subcostal spots beyond the cell of primaries, in the more 
emerald-green colour of the spots of the oblique postmedian 
series, in the continuation of this series to the inner margin 
by the introduction of two large spots placed transversely 
instead of the three small obliquely placed spots of Z. agamem- 
non, thus leaving a clear space throughout between the post- 
median and submarginal series, in the more uniform size of 
the spots of the latter series (which terminates in two small 
unequal spots in place of the large double one of Z. agamem-
