Fig. 5. Using this as a basis of separation we examined over 

 100 specimens contained among Dr. Barnes' duplicates and 

 divided them into two groups ; we next separated the sexes in 

 each group, a task over which great care must be exercised, 

 for in many males the sex-mark is quite faint, and in certain 

 females, owing to the distribution of blue scales, a dark patch 

 like a male sex-mark appears in the cell, in doubtful cases 

 recourse must be had to an examination of genitalia. The net 

 result was that in one series we had specimens as represented 

 by our figures No. i and No. 6, and in the other series insects 

 corresponding to Nos. 2 and 7 ; the former are male and female 

 leda: the latter the two sexes of ines. Even to the casual ob- 

 server the much greater extent of the blue surface in ines on 

 both wings and in both sexes is apparent; naturally slight de- 

 viations occur, but it may, we think, be stated as a general rule 

 that in leda the blue scaling of primaries in both sexes never 

 extends more than two-thirds along the inner margin and is 

 scarcely to be seen in the cell ; on the secondaries in the male 

 sex it never extends upwards along the outer margin beyond 

 the small tail, whilst in the female there is always a distinct 

 dark costal margin extending downwards to about this same 

 tail. In ines, on the other hand, the blue on primaries in the 

 male is even more extended than in female leda, occupying 

 the basal portion of the cell and approaching close to the anal 

 angle ; on the secondaries it extends upwards considerably be- 

 yond the small tail. In the female it covers close upon half the 

 primaries and the whole of the secondaries, with the exception 

 of an extremely fine marginal line of black extending from 

 costa half-way to anal angle. Edwards certainly mixed his 

 sexes in the description of ines, as Messrs. Haskin and Grinnell 

 rightly surmised ; his male is without doubt the true female, 

 and Holland's figure (Plate XXIX, Fig. 35) is also that of 

 the female : what Edwards' female was is a little difficult to 

 tell from the short description ; it might be the male of ines or 

 even the female of leda this is, however, of no great import- 

 ance, as it is the first portion of the description which defines 

 the specific name. With regard to Wright's figures, which are
