cent-shaped markings on the hind wings open outwards, while in Myrina 

 they are much hghter and open inwards. There is, of course, no simi- 

 hirity between these species on the under side. 



Freya is strikingly different from Chariclea upon both the upper and 

 the under surfaces. Above the colour is duller and the bases of the 

 wings are very heavily shaded ; in fact, in the case of the secondaries, 

 this shading extends over nearly the half of the wing. In Chariclea the 

 black so-called mesial band is composed of a series of almost straight 

 bars placed rather irregularly, while in Freya it is made up of a series of 

 deep lunules. A like difference may be observed on the secondaries, but 

 it is not quite so marked. On the under side of primaries similar differ- 

 ences are observable, although the markings are lighter; but the under 

 side of secondaries show the most marked differences, for the beautiful 

 band of pearly lunules crossing the wings just outside of the mesial black 

 band in Freya has no counterpart in Chariclea and the course of the 

 black band in its deep lunules is also very distinct. 



There are many other points of difference between these species, but 

 it is not very easy to indicate them clearly without going into a tedious 

 description. 



Mr. Scudder's descriptions of these species being reversed, what he 

 says of Freija belongs really to Chariclea, and vice versa. These de- 

 scriptions are given in great detail and are generally correct, but contain 

 several curious errors. For instance, in describing the primaries of his 

 Freija, but really Chariclea^ he says : " Within the mesial band are 

 three narrow transverse bands crossing the cell, the innermost not reach- 

 ing the median nervure ; within these is a small lunule opening outward." 

 Surely he should have said inward, as the concave side of the lunule is 

 towards the base of the wing. I might also allude to the fact that he says 

 that the mesial band starts " a little beyond the middle of the costa "; as 

 it really starts at a point very nearly two-thirds from the base of the wing 

 I consider his statement rather loose for a man as particular as Mr. Scud- 

 der is known to be. Similarly in describing Freya, or Freija, he says 

 that the black mesial band of primaries starts at the middle of the costa, 

 while it is really not less than three-fifths from the base. In describing 

 this form he omits to mention the small lunule inside the three bars cross- 

 ing the cell, though it is recognizable, at least in my specimens, in spite 

 of the heavy shading just inside of it, and he also fails to observe that the
