OeryduB irroratus, var. assamensis, Doherty, Journ. As. Soc. Bengal, 1891, p. 37, pi. 1, fig. 7. 

 Gerydtis irroratus, Bingham (part), Fauna of Brit. India, Butt. ii. p. 295 (1907). 



Imago. — Above unmarked except by a small, pale, lougitudinal area around the base 

 of the upper median vein on the forewing. Below pale grey-brown, without the dark 

 markings of G. hoisduvali ; 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 angle of the forewing above. 



The figure represents the transverse ))and of the hindwing incorrectly ; it is really 

 composed of separate annular lunules (Doherty, I.e.). 



Habitat. — Dhansiri Valley, 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.
