much, however, for size and distinctness, like Groum-GI-rshimailo's 

 figure in the fourth volume of the Eomanoff Memoirs. Neither in 

 my specimen or in the figure of adinides is any trace of the completion 

 of the ocelli on the hind wing as in gravest. Beneath they are much 

 alike, with the same difierences as in the male, viz., in gravesi, row of 

 spots (upper wing) less incurved at costa, white dash (hind wing) 

 shorter, red marginal spots well developed up to costa fore wing, and 

 all the markings brighter and crisper and more like, in that respect, 

 medon. The ? adinides may not be so fresh, but it seems in fine 

 condition. 



In gravesi ? the outer fringe which is white, in (^ is dark on fore 

 wing, except at extreme apex, and has a good deal of dark shading in 

 hind wing, but may be called white. In adinides $ specimen and 

 figure it is white, faintly tinted in specimen. There is on both 

 surfaces of A. adinides $ a faint trace of blue, that is wholly wanting 

 in A. gravesi. 



Icarus, amor, and venus, in various respects resemble gravesi. 

 The most obvious point of difference is in the presence in them of the 

 basal spots beneath fore wing, but this is too variable a character to 

 have much value ; the real distinction is that they belong to the genus 

 Polyommatus, and gravesi is an Agriades. These two genera are at 

 once recognisable by the genitalia, the form of the sedoeagus being 

 characteristic (Ent. Rec, Vol. xxii, p. 100). The genitalia of gravesi 

 are remarkably close to those of escheri, and though the general 

 aspect of the two species is very different, in essentials (pattern of 

 markings, &c.), they are certainly very close. Escheri has also many 

 local varieties, some of which make a certain approach to gravesi, and 

 as it is not known so far east as the habitat of gravesi, we may, with- 

 out calling them conspecific, regard gravesi as representing escheri. 



The principal difference between the appendages of gravesi and 

 escheri is in the terminal serrations of the clasps. I have found no 

 specimen of escheri identical in this feature with gravesi, but there is a 

 good deal of variation in this structure in escheri, and no very great 

 further variation in one direction would make them alike. We may 

 take it, however, that this further variation on the part of escheri 

 would carry it beyond its present specific boundaries. A point, whose 

 importance it is diflBcult to weigh, is, that the whole appendages in 

 gravesi are smaller than those of escheri, about as 6 to 6. Such a 

 difference does not always imply specific distinction.
