This species is easily distinguished by its smaller size, the blue 
in the primaries is confined to the cell, to below vein 2 including 
all the area below the cell, but not reaching into the tornus; in the 
secondaries the whole of the wing is bright blue to vein 6. The 
underside pattern is very typical, very irregular as to its postmedian 
stripes, but not absolutely fractured as in the type of the genus. 
The species should be easily recognisable. The female is entirely 
brown above.

Type in Mus. Brit. 
Though this species is decidedly smaller than the type 
species, I have no hesitation in placing it in this genus, 
the pattern obtaining in precisely similar fascies ; the eyes 
of my male, whilst not glabrous, yet are not hairy—in the 
female they are hairy. I do not, however, trust this 
character, my doubting it seriously has made me test it, 
and I have found it very easily removed. Lycaenesthes 
larydas, Cram., has densely hairy eyes; in one specimen of 
this insect I removed the hairs with a gentle application 
of a soft camel-hair brush, in two other specimens this 
failed, but they immediately yielded to a quite gentle 
treatment from a small hogs-hair brush. This shows that 
as a character it should be used with very great caution 
as it is open to accidental alteration. 
Genitalia .—The harpago is reduced to an exceedingly narrow 
process for the basal half being highly and sharply excavated on 
its upper edge, forming a sharp tooth, the curve below being very 
rapid, the lower portion is then produced forward into a long, 
sharp point rather longer than the basal part; the cingula is well 
developed, its basal hind extremity being projected backwards 
into a long, bluntly ended tube, its girdle expands rapidly to the 
cheeks of the tegunien which are very fully developed with a fairly
