larger and paler towards costa, the inner series terminating in 
a white subcostal spot; a second white subcostal spot is placed 
nearer to the base at the extremity of a fulvous stripe which 
borders the basal portion of the subcostal vein and its first 
branch ; the tawny borders of the ocelloid discal series of spots 
are more isolated, the inner series less lunate; the body is 
black above, the autenne tipped with fulvous, the thorax with 
two spots of ochreous behind the collar; two lateral white 
spots in the middle and two behind; the abdomen is spotted 
in front and narrowly banded behind with ochreous. The 
coloration and general pattern below are most like those of 
S. dirtea of Java, but differ im the decidedly more tawny 
ground-tint, excepting towards the abdominal border of 
secondaries (the area around which is, as usual, pale bluish), 
in the broad white belt on the disk of primaries, and the black 
edges of the discoidal and supradiscoidal spots of secondaries. 
Expanse of wings 102 millim. 
This is one of the most handsome species in the genus; it 
approaches nearest to two females in Hewitson’s collection 
regarded as my S. canescens, but decidedly larger than the 
type of that species ; the latter, however, may vary, though 
certainly not sufficiently to include the Macassar female asso- 
ciated with it by Hewitson, and which is nothing more than 
the more prevalent variety of the insect described by Hewit- 
son as the female of his 8. wetes of Menado. 
The true female of S. wetes is in Hewitson’s collection from 
Tondano ; and, excepting that it is larger, differs in no respect 
from the male. ‘The female of the Macassar species, however, 
is larger still, and has the general character of markings of S, 
dirtea, excepting that the spots of the discal series, including 
the spots of the inner series of the furca, are larger, and thus 
form an angular band broken up into well-separated spots 
below the median vein, but only interrupted by the black 
nervures above it; the entire furca is occasionally composed 
of white spots, as in the type of Hewitson’s description. The 
male differs chiefly from that sex of S. wetes in the larger 
white spots of the inner series of the furea on the primaries 
and in the narrow inner border of the ocelloid spots on the 
secondaries, so that there is no well-defined grey band across 
these wings as in S. eetes. I propose that this species should 
take the name of S. phasiana: so far as I know it occurs only 
at Macassar, the pair in our collection being taken in that 
locality, as well as one of Hewitson’s females; a pair in his 
collection, however, is only labelled ‘‘ Celebes,” but was pro- 
bably obtained from the same source as our examples. .
