upper side of the hind wings in E. cyanca is bright blue, while in E . cwrulescens this 

 area is dull greenish blue. On the under side in E. cwrulescens the cell of the 

 fore wing is solidly blue at the base, in E. cyanea this region is green or greenish 

 ochraceous. The dark spots in E. cyanea which appear in the cell of the fore wing are 

 much smaller than the corresponding spots in the wing of E. carulescens, and this holds 

 good also of the spots of the hind wings on the under side. Below the red costal band of 

 E. C(jc7-ulescens (Vide Aurivillius, 1912, Seitz, Gros.s-Schmett., XIII, PI. XLiva, 

 where the under side of E. coendescens is shown, in error named E. gausape) large dark 

 spots intervene between the red costal band and the rest of the wing. This is not the 

 case in E. cyanea. There are no such spots, or they are at most feebly indicated 

 by a faint dark shade near the basal end of interspace 7. The spots in the cell of the 

 secondaries are also very greatly reduced or disappear and the discal spots beyond 

 the cell in E. cyanea are smaller and the red of the costal border in some speci- 

 mens spreads downward into the discal area of the wing, as a faint reddish shade. 

 The females in E. cyanea are marked exactlj' as are the males, but have much 

 greater expanse of wing, and the postapical band of the primaries on the upper side 

 is paler blue. The postapical band of the primaries is less prominent on the under 

 side in both sexes of E. cyanea than it is in E. cwrulescens, and in some specimens 

 scarcely appears. Expanse, d^, 60-65 mm.; 9 , 70-85 mm.

The Expedition l^ro tight back fourteen males and five females of 

 this species, which I have carefully compared with a series of male 

 specimens of E. coerulescens which I have in my collection from the lower 

 banks of the Ogove River. The specimens were all captured at Medje, 

 two males in April, the rest from July to September. Two of the males 

 are aberrant in that they show a tendency in the postapical band of the 

 primaries on the upper side to become whitish towards the costa.

The collection contains four males of this well-defined species which 

 were taken at Medje, two in June, one in July, and one in August. The 

 specimens agree perfectly with a series in the possession of the writer, 

 which were collected for him many years ago by Mrs. Reutlinger at 

 Benito, Spanish Guinea.
