the pseudoneura more distinct, and the subconical brown 

 dentation almost disconnected from the brown area of the 

 cell ; all the grey adnervular rays are rather more pro- 

 nounced, and there is a supplementary ray bordering the 

 submedian nervure — and a small one on the submedian 

 fold or sinus. Posterior wings, with a fairly extensive 

 golden-yellow area ; this yellow occupies nearly half the 

 discoidal cell — distal end : a very small section of it also 

 in the space between the 1st and 2nd subcostal nervules, 

 without the cell, and the remaining yellow area encloses 4 

 pyriform, black marks, in some examples confluent with the 

 broad dark submarginal border, in others slightly separated 

 from it by the yellow : the first of these, between the 2nd 

 and 3rd subcostal nervules is the largest, the next below 

 is the smallest, and the remaining 2 are slightly longer ;

2 Anterior wings warm dark brown, lightest towards 

 the base of the wings, with about 8 adnervular grey white 

 rays, subdued by brown scales ; the veins all delicate but 

 well expressed. Within the discoidal cell the outer half 

 is grey-white bordering the submedian, median, and 

 discocellular nervures, of irregular width, with a central 

 broad dentate or subconical extension of the dark area 

 of the rest of the cell, through which the 2nd pseudo- 

 neurus is revealed by a fine streak of grey. Undersurface 

 of the wing similar, but the grey of the cell is broader in 

 every detail, and the central streak of grey also broader — 



in all the examples I have seen these marks are very con- 

 stant in shape, and graceful ; a dark orange-grey mark is 

 curved by the 3rd median branch and the submedian vein . 

 all the remainder of the wing is dark velvety brown ; the 

 veins are dark brown and strongly expressed in the 

 yellow. 



Under surface of the Anterior wing as above, except that 

 the dark parts of the wing are lighter, as are the light rays 

 and light parts of the cell. Under surface of the posterior
