no way of certainly determining this. The association of the sexes in 

 some species of this genus without the help of correct data obtained in 

 the field is a matter of conjecture, as the females of related species are 

 very much alike.

The collection contains sixty-five males and forty-one females of 

 this species and its varieties. The males are all quite alike, except seven 

 which do not have the ground-color of the wings a bright pale orange- 

 yellow, which is the normal color, but are dull brownish, and the darker 

 markings are not deep black but grayish black. There is also a single 

 female which, in these respects, is like the males I am describing and 

 agrees perfectly with the description of a female to which Eltringham 

 applied the subspecific name oi fumida (cf. Eltringham, loc. cit.). The 

 name used by Eltringham is, in my judgment, also to be applied to these 

 males, and the aberration is evidently not in this case confined merely 

 to the female sex. Most of the aberrant female forms described bj'^ 

 authors are represented in the batch of specimens before me. There are 

 several specimens referable to the form dubbed macarina by Dr. Butler, 

 in which the margin of the hind wings is not marked with a dark band ; 

 of the form named aurivillii by Dr. Staudinger, in which the hind wings 

 are crossed on the middle by a band of white of varying degrees of in- 

 tensity; and of the variety named bakossua by Strand, in which the 

 costal third of the transverse median band of the fore wings is whitish. 

 And there are some intergrading forms which the writer, if he were a 

 professed ''species-maker" and not engaged in other and more important 

 matters, might be tempted to describe and tag with so-called subspecific 

 names. These forms are mimetic, and some interesting observations 

 concerning them are contained in Eltringham's work which is cited above.
