312 Dr. T. A, Chapman on 



in lefehvrei $, but in mdas $ and ncrine ^ it is a more or 

 less continuous narrow band, its basal margin cither quite 

 straight or more or less indented at the veins. In the $ $ 

 of all it is more or less broken into lunules separated by 

 the pale band stretching along the veins either almost or 

 quite to the cilia. 



The basal margin of the pale band is however by no 

 means the same. It is so nearly the same in the two 

 sexes that we may treat of them together. In Icfebvrei, 

 this margin begins on the costa at much the same place 

 as in the others, and crosses the wing in the same curves 

 as in mdas and ncrine, but much less pronounced, so that 

 though one could not call it straight, it is almost so in 

 comparison with their more marked curves and indenta- 

 tions. When it reaches the third (there are usually 3, 

 there may be 2, 1 or none, I have no specimen with 4 on 

 the under-side) ocellus between veins 2 and 3 it is 

 very close to it, about the width of the (average) ocellus 

 distant from it, and proceeds down and reaches the margin 

 in the next interspace (between veins 1 and 2). In ncrine 

 and melas this line is more curved, in ncrine almost always 

 markedly so, in 7iielas only a few specimens have it so 

 curved as in nerine, but all much more so than in lefehvrci. 

 By curved I mean especially the rounded projections be- 

 tween veins 3 and 4, and between 4 and (5, with the 

 marked indentation on vein 4. When opposite the last 

 ocellus (between veins 2 and 3) it is a long way from it, it 

 proceeds very well-defined across the next interspace and 

 reaches the hind margin to the inner-side of vein 1. This 

 difference amounts practically to this transverse line at its 

 inner extremity reaching the margin of the wing on the 

 hind margin in Jrfchvrci, on the inner margin in mclas and 

 nerine. 



It may be further noted that as in the front-wing, so in 

 the hind one, the third ocellus especially is much nearer the 

 hind margin in Ic/chvrci than in melas (or nerine), and is 

 nearer also in comparison with the 2 (usually 2) others. 

 I was, at one time, convinced that there was a difference 

 in the form of the wings in the two species, lefehvrci and 

 melas. 



I have been quite unable, however, to substantiate this 

 opinion by wing measurements. The strong impression 

 one has, however, to this effect, is not hallucination, it is 

 probably the result of the different positions of the ocelli
