E. imperialis Lindemans. The very beautiful $ on which this species is based closely approaches imperlalks. 
E. luperca (45 a). Whether it is only a form of this or an independent species can only be decided by com¬ 
paring larger material. Both wings blackish above, the basal part tinged with dark green to beyond the middle; 
the subapical band of the forewing is about 6 mm. in breadth, bright ochre-yellow, and reaches vein 4, but 
is then continued by a band running parallel with the distal margin at a distance of about 8 mm.; this band 
is orange-yellow in cellules 3, 2 and the anterior part of cellule 1 b and bluish at the hindmargin; on the hind¬ 
wing it is continued by a somewhat narrower blue transverse band nearly to the anal angle; the fringes of the 
hindwing are pure white; the under surface is light bluish green and marked almost exactly as in luperca , 
only differing in having the white subapical band of the forewing connected with vein 1 by a white transverse 
line and in the broad white transverse band of the hindwing being quite straight and hence at vein 4 nearly 
9 mm. from the distal margin. The white apical spot of the forewing large on both surfaces. Cameroons. 
E. symphona Baker. The descriptions runs: “<J. Palpi ochreous below, with a dark lateral stripe, symphona. 
fringed palely with longish hair above; head blackish, with two whitish dots below the antennae and two 
larger ones above: eye-sockets edged with white. Both the wings deep bronzy green, much deeper in tone 
near the termen: primaries with the area between the cell and apex darker, with an irregular oblique 
white stripe from vein 8 to just beyond vein 4, a small white patch at the apex; fringes with fine, short, 
white internervular intersections. Underside: both wings dull sienna-brown: primaries with two black spots 
lengthwise in the cell and a smallmne closing its upper extremity; all the white marks of the upperside show 
through: secondaries with two black spots in the cell and one at the extreme base, all in line; area above vein 
8 crimson, below which to the lower margin of the spots is an indefinite patch of pale greyish, with a trace 
of the usual pale-angled dash between veins 7 and 8 about midway along the former. There is the least trace 
of a row of subterminal spots in a very slightly paler subterminal area in both wings.” I have since had an 
opportunity of examining a specimen of this interesting species and find that it belongs to the genus Euryphene 
and is nearly allied to rubrocostata Auriv., with which it also agrees in the colour of the palpi. Congo region: 
Beni Mawambe. 
3. Ceres Group. 
In the forms of this group the upper surface of the h in (Irving usually bears a row of large, rounded, black, more or 
less sharply defined submarginal spots (cf the figures on plate 43); occasionally these spots are green or bluish The under 
surface is usually characterized by sharply marked, black discal and submarginal spots; only in a few extreme forms these 
spots are indistinct or entirely absent, so that these approximate to the species of the preceding group. The variability of 
the forms reaches its maximum in this group and it is possible that we are only dealing with 3 or 4 actual species. In 
order to facilitate the determination of the numerous forms they may be divided into three subgroups. 
First Subgroup. 
Hindwing beneath with a broad red longitudinal stripe at the costal margin, which extends to beyond the middle 
of the whig and also covers a larger or smaller part of cellule 7. Occasionally the red colour covers a great part of the hind- 
wing. 
E. xypete. The apex of the forewing on both surfaces white for a breadth of 2 — 5 mm.; the submar¬ 
ginal spots of the under surface are more or less completely divided in two and placed only 2—4 mm. from the 
distal margin; the red costal stripe on the underside of the hindwing never entirely covers the base of cellule 7; 
the wings above with blackish ground-colour. — xypete Hew. (44 b). The under surface of the hindwing xypete. 
broadly suffused with red not only at the costal margin but also in the middle between veins 2 and 7; the 
subapical band of the fore wing is light yellow or whitish, edged with bluish, reaches vein 3 and is posteriorly 
not at all or but little widened; base and hindmargin of the forewing more or less extended blue-green; the 
hindwing shining blue-green above with broad blackish marginal band, in which the deep black submarginl 
spots often only stand out distinctly in certain lights. Under surface with sharply expressed black submarginal 
spots; forewing with three or four black spots in the cell and large black discal spots at the proximal side of 
the subapical band; hindwing only in the cell and at the base of cellules 4—6 (—7) light green with black 
spots, otherwise bright red, at the inner margin yellov r and at the distal margin light green to yellowish green 
with black marginal line. Sierra Leone to Angola. — mirabilis Bartel only differs in having the scarlet colour mirdbilis. 
on the underside of the hindwing confined to the costal part and not reaching beyond vein 7; the middle of 
the hindwing beneath is yellowish green. Cameroons. — bombeana Strand is similar to the preceding form, bombeana. 
but the subapical band is whitish, broader, and posteriorly more widened (6 mm., in cellide 4 nearly 10 mm. 
in breadth). Cameroons. — In crocked Btlr. the subapical band of the forewing is indistinct and not dif- crockeri. 
fering from the ground-colour; the hindwing beneath is only red at the costal margin, the red colour not extend¬ 
ing posteriorly beyond vein 7; the ground-colour of the under surface is yellowish green, at the termen distally 
to the black submarginal spots dark brown. Ashanti and Niger. — crossei E. Sharpe ( = aureofasciata Lathy) crossei. 
differs from crockeri in having on the forewing a broad gold-yellow subapical band and a greenish hindmarginal 
spot, yellowish in the middle. Niger. — caerulescens Smith (44 a, as gausape) approaches the form crockeri, caerulescens. 
but has the subapical band of the forewing light bluish, posteriorly widened and often reaching vein 2, the
