black except for a few stray yellow scales as far as vein 2 ; beyond 

 as far as vein 7 is a yellow band considerably suffused with black 

 scaling on the portion within the cell, and with the veins showing 

 plainly black scaled. 



Habitat. French Guiana, St. Laurent de Maroni. 



Type in coll. Joicey. 



This specimen, apart from its strange colouring, has a 

 peculiar aspect in the apical third of the wing. It there 

 has a whitish appearance, caused by a regular and sym- 

 metrical loss of scales. We have not had this shown in 

 the figure, for it is most probable that when the insect 

 was fresh, no such loss of scales was to be detected. The 

 specimen is far from fresh, and we have thought it best to 

 figure it as normally scaled.

Variation of the Hind- wing. 



It has already been shown how the forms divide up 



primarily into three sections : (1) A black hind- wing, 



125 examples; (2) a red streak at base, 420 examples; 



(3) a completely streaked hind-wing, 186 examples; thus
