S. Upjjerside.—FoTewmg : yellow subbasal interspace strongly narrowing 

 costad, triangular ; subapical e->-mark centred with a yellow streak, the pro.xiiual 

 and posterior edges of the spot remaining pare black ; the yellow spot SC — SC* 

 situated immediately behind the n-mark smaller than spot SC^ — SC'^ ; subapical 



submarginal yellow dot small, rounded. Hindwing: first submarginal spot 



usually orange ; tail more or less strongly spatulate, asymmetrical. 



Underside. — Forewing : e->-mark broadly centred with buff", the black border 

 .around the bull' spot SC^ — SC^ remaining pure black, the butf-scaling of the c-»-inark 

 continuous with the similarly coloured powdery line situated on the black postdiscal 

 band; the buff scaling absent from the c-»-mark in one of our British Columbian 



specimens, the "-mark being much reduced in the individual. Hindwing: the 



last two submarginal spots orange, some of the other submarginal spots being also 

 more or less washed with orange ; disc with some more or less large orange patches 

 H2_SM- situated prosimally of the black postdiscal line. Several melanistic males 

 have been found. 



? . Dichromatic in the southern districts. One form similar to male, the black 

 bands more extended and the blue patches of the hindwing orange, more or less 

 rounded. The second form of female blackish brown, the black bands more or
