GERYDUS ASSAMENSIS. 
Plate 614, figs. 3, 3a, $. 
Gerydus irroratus, var. assamensis, Doherty, Journ. As. Soc. Bengal, 1891, p. 37, pi. 1, fig. 7. 
Gerydus irroratus , Bingham (part), Fauna of Brit. India, Butt. ii. p. 295 (1907). 
Imago.— 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. boisduvali; 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 sub-apical, 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 sub-marginal dark line. 
It resembles G. melanion from the Philippines, but is without the white area near 
the lower ansde of the forewin o- above. 
The figure represents the transverse band of the hindwing incorrectly; it is really 
composed of separate annular lunules (Doherty, l.c.). 
Habitat.— Dhansiri Talley, Naga Hills. 
We have not seen this species; the unique type is in the Indian Museum, 
Calcutta ; the figure is copied from Doherty’s figure.
