E. ochreana Lathy is distinguished by the much lighter ground-colour of both wings. The forewing ochreana. 
shows hyaline spots in 1 b to 3, 6 to 9, and in 11, and the usual two spots in the discal cell. The discal 
spots 4 and 5 are, at least in the typical specimen, only represented by black spots. Nyassa Land. 
E. denuba Plotz (= decolor Mah.) (76 d, e). The light ground-colour of the hindwing is generally a denuba. 
pure whitish yellow, not light grey as in the figures. The forewing exhibits the usual two hyaline spots each 
in the discal cell and in 1 b, and one each in 2 to 9 and in 11; the spot in 2 is large, almost square, and 
is more remote towards the base than the spot in 3, right behind the second spot of the cell. Hindwing above 
at the base, at the hind-margin, costal margin and apex dark grey or brown; it shows two black spots in area 7, 
one each in 4 to 6, and two small or indistinct ones in 1 c. Sierra Leone to Cameroon.

side and could therefore not be ranged in the review. Angola. Rhodesia. 
E. landbecki H.-Drc. (76 e) is distinguished from the other species by the hyaline spots of the hindwing, landbecki. 
The forewing shows one hyaline spot or dot each in 1 b to 9 and in 11, and two in the discal cell. From 
the other species it [is also distinguished by the area 1 b showing but one spot and by the spots 1 to 4 
being situate in a straight line towards the apex of the wing. It is doubtful whether it is a genuine Eagris.

E. phyllophila Trim. ( = ophion Wallengr.) (76 c, d) is easily recognized by the figure. Natal. De- phyllophila.

E. fuscosa Holl. (76 d) is easily discernible from E. ‘phyllophila by the marks stated in the review, juscosa.

9. Genus: Sarangesa Mr. 
This genus is very badly defined from the other genera. But as I have no time nor material at pre¬ 
sent- for making a revision of the genus, I follow rather closely the classification of the species hitherto main¬ 
tained. 
Review of the Groups of Species. 
A. Margin of hindwing deeply emarginated between the veins 4 and 6, fringes at the said veins prolonged, 
dentiformly extended. Median of forewing between the veins 2 and 3 quite straight; lower discocellular of 
fore wing straight and almost vertically placed towards vein 4. — <$ posterior tibiae with a long hair-pencil. 
First joint of posterior tarsi with appressed scales, without hairs. — Eretis Mah. First Group. 
B. Margin of hindwing uniformly bent, between the veins 4 and 6 not or only slightly emarginated; fringes 
equally broad, undulate or almost entirely margined. The median of the forewing is slightly bent between 
the veins 2 and 3. 
oc. Vein 5 arises in both wings distinctly nearer to 6 than to 4; the anterior discocellular of the forewing 
is of a slanting position. — $ posterior tibiae with a hair-pencil. First joint of posterior tarsi above 
hairy. Second Group. 
p. Vein 5 arises in both wings midway between 4 and 6; the lower discocellular of the forewing is straight 
and almost vertical towards the vein 4. 
*. <$. Posterior tibiae on the back part covered with long hair, but without a real pencil. First joint 
of posterior tarsi with appressed scales, but no hair. -— Hyda Mah. Third Group. 
**. 3 . Posterior tibiae with a long hair-pencil. First joint of the posterior tarsi above hairy. (I am not 
certain whether this is the case in all the species.) Fourth Group. 
First Group of Species. 
The species of this group, on an average, are smaller, with broader wings than those of the second 
and fourt h groups, and particularly distinguished by the irregular, dentate margin of the hindwing. The margin 
of the fore wing is also more or less emarginated between the veins 1 and 2. Hindwing without hyaline spots; 
forewing usually with small hyaline spots in 1 b, 2, 3, 6 to 8 and 11, but rarely in the discal cell. Wings 
above dark brownish-grey with black spots arranged in transverse bands or transverse rows. The $$ show 
a lighter ground-colour and more distinct marking.
