Genus Theix, novum. 
Male, forewing with the subcostal vein five-parted (including the 
vein itself as a bi-anch), the first branch originating one- third before the 
end of the cell, the third a little before the end, the second nearer the first 
than the third, the fourth from the third halfway to the apex, the fifth close 
to the apes, very short. Discocellular veins nearly straight, the lower 
half again as long as the upper, cell slightly longest at its lower angle, 
second bifurcation of the median vein a little before its end. Snbmedian 
vein exceedingly remote from the median, straight for nearly half of 
its length, then bent downwards like a bow. In the interno-mcdian space 
discally, there is a deep oblique depression on the upperside, covered 
with short grey down, and bearing a conspicuous extensile tuft of long 
orange hairs produced downwards and outwards over the depression. 
Hindwing with the two lower median branches forking simultaneously 
from the end of the cell ; a loug tail from the submedian, a short one 
from the lower median vein. 
The curious scent-organ in the middle of the forewing of the male, 
resembling that of Dacalana and Arrhenothrix, has so distorted the 
venation that I have thought it advisable to separate this genus from 
N eocheritra. Whether the male has five and the female four subcostal 
branches, as in that genus, I do not know. 
7. Theix gama, Distant, ( Neocheritra gama). 
Above black, a tuft of orange hairs ovor a small grey cavity in the 
middle of the forewing. Hindwing with the lower part white, con- 
taining two black spots ; above this grey, with three black spots on the 
boundary between the grey and the white ; the upper part of the wing 
black. Below as in the female. The species apparently mimics 
Rooxylides tharis. 
Rare at Padang Rengas, Malay Peninsula. I have also taken it in 
the mountains of south-western Sumatra. 
Subfamily PORITINM. 
Genus Massaga, mihi. I find that in the male of M. pediada, the 
type of this genus, there is a narrow tuft of prostrate black hairs arising 
at the end of the cell, extending beyond it along the upper border of the 
upper median vein. This was pointed out to me in M. pharyge by Mr. 
de Niceville and I afterwards found it in M. pediada. In M. potina it 
is apparently present, but very small and inconspicuous. In all these 
species the upper tuft is of considerable size, yellowish or whitish, turned 
upwards along the upper subcostal vein, in a large whitish patch. In
