 shining light blue scales. Outer marginal row of black spots

The indentation on the outer margin of hind wing is 

 scarcely discernible in this form. 



The female described is from a specimen in Dr. Staudinger's 

 collection, and is, perhaps, exceptionally large.

Epimastidia pilumna, sp. n. 



(J . Allied to E. itiops, Feld. Upperside casrulean blue, 

 narrowly edged with blackish brown ; costal third of hind 

 wing greyish brown, except along the costal margin, which is 

 pure white ; three more or less distinct black spots towards 

 the anal angle, adjoining the black border, that between the 

 first and second median nervules being the most distinct. 



Underside : costal margin of fore wing rather more broadly 

 bordered than in E. tnops, and with a narrow greyish line 

 partly closing the cell ; outer marginal border consisting of 

 lunules as in that species, but larger and more distinct. Hind 

 wing with the inner band broader and the lunules and spots 

 much larger, so that the white band between the brown border 

 and the inner row of black lunules is reduced to a line of 

 white crescent-shaped markings bordering the large black 

 lunules. On the inner edge of the brown band, about the 

 middle of the wing, is a slightly irregular line of faint grey 

 markings indistinctly edged with white. The three lower 

 black spots in the marginal series are more or less suffused 

 with light shining blue scales. 



? . Upperside much as in E. inops ? , but the bases of 

 both wings strongly suftuscd with greenish blue. 



Underside as in male, except that the inner margin of 

 fore wing is white, not brownish grey as in that sex.
