IN BUTTERFLIES 225 



(Chrysoplianini.) We have one species in whicli 

 both sexes are fiery red marked with black ; an- 

 other where both are fulvous marked with black ; 

 others where both sexes are brown ; and several 

 where the male is brown, marked with fulvous, 

 and the female fulvous, marked with brown; 

 others where the male is wholly brown, and the 

 female fulvous, spotted with brown; and again 

 others with fiery male and brown female. We 

 have nearly every possible variation, but the prev- 

 alent feature is a dark male, often with more or 

 less metallic reflections, which sometimes increase 

 so as to give the insect a fiery copper hue ; and 

 a fulvous, spotted, and margmed female. I do 

 not see how we can possibly discover, with any 

 certainty, from within the limits of the gToup of 

 coppers, what should be considered the normal 

 type. Nor are we much better off in an exami- 

 nation outside the gTOup ; there the prevailing tint 

 is either brown or blue ; and I am inclined to 

 think that brown, tending strongly to copper, 

 should be considered the normal type ; in which 

 case the males are normal, and the species gen^ 

 erally antigenic.
