Fruhstorfer distinguishes these two species thus : 

 lynceus, noticeable for the dense blackish dusting on the 

 upper side of both wings, while in logani the ground-colour 

 is lighter and the blackish dusting on the upper side is 

 reduced. Admittedly these Hesiias are ver>' variable ; so 

 much so that other writers have regarded lynceus and 

 logani as but one variable species. Breeding experiments 

 will alone decide the point, although Fruhstorfer regards 

 certain differences in the genitalia as " of such decisive 

 significance that the specific rank of logani cannot be ques- 

 tioned " {I.e.). Piepers 2 doubts the value of these differ- 

 ences in genitalia. 



' Frulistorfer recognizes another subspecies, H. I. hypata 

 Fruhst. from the Sulu Islands to the North of Borneo, i.e., just 

 outside the limits of the Malaysian subregion. 



'PiEPERS, 1913, p. 21, writes : "Dr. Henri de Graaf a specialist 

 in this kind of researches, has investigated microscopically 2.^ 

 specimens from my collection, both light and dark coloured, and 

 he did not find a single one amongst them whose genitalia agreed 

 with the figure given of those of stolli, on the contrary they all 

 agreed with those given of logani, and although considerable 

 individual differences were observed in this respect it was only 

 as regards the form of the valvae and valvulae and not to such 

 an extent in connection with the structure of the principal organs 

 that the existence of more than out species could be inferred 

 from it."
