along the veins and on each side of thera forming an irregular submarginal dark 

 line ; these veins are also tipped with dark brown on the margin. 



UiuliTsiili' resembles the inale, but the bars and spots are darker rufous. 



Expanse of wings : 1|- inch. 



A verv beautiful and distinct insect. The male somewhat resembles H. 

 eudftus Feld. on the upperside, but tlie blue area is very much more extended. 

 The female on the upperside approaches //. apelles in colour, bnt is paler. Two 

 males and iowT females are in the collection.

Male. — Upperside : anterior wings dark blackish brown sutfused with purple 

 except towards the apex and partially along the outer margin. Posterior wings 

 brilliant metallic blue, costal margin broadly brown. 



Uiidersidi- : anterior wings dull ashy brown ; the cell, a short bar at the end of 

 the cell bordered outwardly by a silvery bar, and the costal margin nearly to the 

 apex dark ochraceous, a metallic silvery blue streak in the middle of the cell 

 from the base to its end, where it bends downwards to the median nervure, 

 another silvery streak along the subcostal nervure extending a little beyond the 

 end of the cell, above and beyond which are four metallic spots tipi^ed with 

 black between the subcostal nervules ; nearer the apex, crossing the disc from the 

 costal margin to the lowest median nervule, is a continuous row of ochraceous 

 lunules situate in a dusky space, the four uppermost with metallic sjjots on the 

 inner side, and there is a submarginal row of metallic spots situate in a pale 

 ochraceous marginal band and tipped internally with black. Posterior wings 

 with a pale patch near the apex, the costa at the base, and five bars crossing 

 the wings rufous, edged on each side with metallic silvery blue, in which are a 

 few black markings, the bars being nearly parallel to each other, except the two 

 outer bars which touch each other on the lowest subcostal uervule ; of 

 these two bars the inner one extends from the inner margin and ceases on the 

 lowest subcostal, the outer bar commences near the apex and ceases on the 

 lowest median nervule. The outer margin is broadly ochraceous and centred 

 with metallic silvery blue, a few narrow black streaks on the inner edge of the 

 marginal band. 



Female. — Uppersidi> with the basal two-thirds pale silvery blue, the ape.x 

 and- outer margin broadly brownish grey. The underside resembles the male, but 

 is rather paler. 



Expanse of wings : 1| inch. 



Four males and three females are in the collection. It is nearest to 

 H. protoffenes Feld., the type specimen of which, a. female, in the Felder collection 

 at Tring, is before me. In this specimen the pale blue area on the upperside 

 is considerably more restricted, and the discal row of brick red lunules on 

 the underside of the jwsterior wings is nearer the outer margin, besides numerous 

 other dilferences. There is no male of H. protogeiies in the Felder collection.
