1891.] W. Doherty — New and Bare Indian Lycrenid®. 
The Species is larger than G. symethus, not quite so large as G. 
ancon. The upper median vein of the male is naked above and swollen 
from the end of the cell one-fourth towards the outer margin. This 
may be regarded as a generic character of Gerydus , since it occurs at any 
rate in G. symethus , biggsii, boisduvalii, heracleion, irrorabus var. assa- 
mensis, and ancon. In G. croton the swelling is indistinct, and the vein 
is covered with black scales. 
9. Gerydus irroratus, Druce, var. assamensis, nov. PI. I. 
Fig. 7. 
Above, unmarked except by a small, pale, longitudinal area around 
the base of the upper median vein on the forewing. Below, pale grey- 
brown, without the dark markings of G. boisduvalii, a small pale area 
on the forewing below the middle median vein, the markings lunular, 
those in the cell of the forewing reduced, the transverse discal band of 
the forewing subapical, extending only to the upper median vein, a single 
conspicuous dark lunule near the lower angle; the transverse band 
of the hindwing regular, an undulated, continuous submarginal dark 
line. 
Dhansiri Valley, Naga Hills. 
It resembles G. melanion from the Philippines, but is without the 
white area near the lower angle of the forewing above. It may be 
conspecifio with Mr. Druce’s G, irroratus (from Siam) which has never 
been figured or properly described. 
I have taken what may be the female of Gerydus irroratus in Perak. 
Some pale markings represent the broken white baud of G. boisduvalii, 
the hind wing is angled at the upper median vein. 
The figure represents the transverse band of the hindwing incorrect- 
ly ; it is really composed of separate annular lunules. 
10. Logania massalia, n. sp., PI. I, Fig. 8. 
Female. Above black, a round, dull white discal area on the fore- 
wing from just above the upper median vein almost to the submedian 
vein. Below irregularly speckled and variegated ; forewing with the 
costal and apical parts ochreons-brown, the rest blackish. Hindwing 
also tinged with ochreous, a submarginal dark area, and obscure dark 
transverse bands. Hindwing not angled, the margin entire. 
Nearest an undescribod Logania from Perak, Malay Peninsula, 
which, however, has the upperside marked as in L. marmorata, and the 
margin undulated,
