and the hindmargin of the forewing much narrowed, and then again becoming broader is rectangularly 
bent round towards the costal margin at vein 3 on the forewing. The under surface is lighter with the ground¬ 
colour red-brown. French and Belgian Congo. 
C. ogova Plotz (36 b) is a female form of uncertain location. It differs from the other $$ of this group 
in having the white median band narrow and dentate on the hindwing, but on the forewing much widened 
towards the costal margin and not there darkened. Cameroons and Ogowe. 
C. hobarti Btlr. is a species unknown to me, apparently nearly allied to sangaris. The is described 
as red above; costal and distal margins narrowly black; forewing with a small apical patch and a subapical 
dot black; the other subapical dots usually indistinct; hindwing with free submarginal dots, only at the costal 
margin and the anal angle with submarginal line; the under surface is yellowish brown with fleshy red and olive- 
coloured reflection and nearly straight dark brown median line. The $, whose identity with the $ is perhaps 
not cpiite certain, Butler describes as follows: ,,The female nearly resembles that sex of C. adela, excepting 
that the basal area is internally suffused with olivaceous greyish and externally with pale sandy yellowish, 
the discal series of sagittate markings is weaker in the primaries and very much more so in the secondaries; 
on the under surface the general appearance is even closer to that of C. adela but the central stripe is straight- 
er and very dark, with the irregular series of spots which bound it internally white, the outer border (excepting 
at its extremities) sandy brown, and the discal markings very indistinct. Expanse of wings 64 millim.“ Uganda, 
in Nandiland. 
2. Genus: Eiipiera Stgr. 
The species of Euptera are small, delicate Nymphalids, which are rare in collections and but little 
known. In the the forewing is short, triangular and at the distal margin deeply emarginate; the hindwing on 
the other hand is produced at the anal angle, broadly and obtusely lobecl. In the the forewing is broader 
and more rounded and at the distal margin not or only slightly emarginate; the hindwing is uniformly 
rounded, hence entirely without anal lobes. Life-history and early stages entirely unknown. 
First Group. 
Hindwing above with two light transverse bands, the first before, the second beyond the middle, the former connected 
with the half-band of the forewing, which consists of three or four spots (in 1 a to 3). 
E. elabontas Hew. (50 d). Both wings are black above with light, yellowish or white, markings; the 
forewing has the following: a longitudinal streak, two dots and a transverse streak in the cell; a trans¬ 
verse streak or a transverse spot in the basal part of cellule 1 a, cellule 2 and cellule 4; a transverse band 
about 4 mm. in breadth in cellules 1 a to 3 and a fine submarginal line composed of proximally concave 
lunules; the hindwing has two light transverse bands and a fine submarginal line, which is similar to that of the 
forewing; close before the distal margin there is further a fine, light, nearly straight line, which, however, is 
often indistinct. The light markings are in the more or less yellow, in the $ white or whitish; they are 
distinct also beneath. Slave Coast to the Congo. — dorothea Bale, is the north-western form and is said 
to differ in the much broader transverse band of the forewing, the streak-like mark ,,in“ the cell (probably 
beyond the cell in cellule 1 b) and the broader transverse bands of the hindwing. Sierra Leone. —- mweruensis 
Heave differs from the typical form in the broader and more continuous transverse bands on both wings. The 
light markings of both wings are light sulphur-yellow in the the under surface is lighter than in the typi¬ 
cal form; seems to me from the descriptions to be the same as dorothea. North Rhodesia. 
E. intricata Auriv. is only known in the female; the markings are similar to those of the preceding 
species, but the ground-colour is lighter, black-grey, only in the basal part darker, blackish, and the light 
markings are rust-yellow in the basal part and in the distal half whitish bordered with yelloAvish; the inner 
transverse band on the hindwing is very narrow and the outer about 3 mm. in breadth; both wings have 
elongate, distally pointed, conical, black submarginal spots, surrounded by whitish, proximally yellowish 
rings; beneath both wings are light whitish with indistinct brownish markings in the basal part and conspi¬ 
cuous, rounded black submarginal spots; 4 or 5 fine black transverse lines in the cell of the hindwing. 
It is possible that this form is only a dimorphic $ of elabontas. Cameroons. 
E. sirene Stgr. is about the same size as the preceding species and lias the ground-colour of the upper 
surface deep black; the light markings of the forewing are sulphur-yellow but much smaller and narrower than 
in elabontas (50 d); the transverse band in cellules 1 a to 2 in particular is narrower, placed nearer to the 
distal margin, and composed of small triangular spots, which form sharp angles with one another; the trans¬ 
verse bands of the hindwing are quite different in colour and form; the inner one is red-brown, begins narrowly 
at vein 1 b and becomes rapidly broader towards the costal margin, where it unites with the outer band; the 
latter is almost triangular, begins at vein 1 b, where it is 8 mm. in breadth, but becomes gradually narrower 
anteriorly and in cellule 6, before it joins the other band, is only 2 mm. broad; in cellule 1 c it is entirely yellow,
