 the alujost complete disappearance of dark bais in the proximal 

 wing-area with the exception of a single isolated little spot, this 

 part of the wing therefore having changed almost entirely to an 

 uninterrupted light field. 



One might feel inclined to conclude from this observation that 

 spot 4 (Smolian's d) differs in character from the rest of the six spots 

 along the front-margin. I doubt however the soundness of tiiis con- 

 clusion, on account of a comparison with allied species, in which 

 this spot, though restricted in the majority of them to the area of 

 the discoïdal cell, yet sometimes shows distinct connections with a 

 light bar extending to the hind margm, q. g. Arctia liebe 2iwe f asciata.
