H. strigula Mab. (28b). Wings above black-brown: the forewing with a small, white-pupilled eye- .s trigula. 
spot in cellule 5 and a large one, broadly margined with yellow, in the middle of cellule 2; the hindwing 
with a small eye-spot in cellule 2 and at the apex of the cell in cellule 3 or 4 some yellow scales. The 
under surface is light yellowish grey, irrorated with brown, and has a rust-coloured median line, which on 
the forewing is curved in S-shape, on the hindwing but little irregular, almost straight; a similar proximal 
transverse line also stands out very distinctly; the eye-spots are placed as above, but smaller. Madagascar, 
subsimilis Btlr. is quite similar above, but differs beneath in having the ground-colour more grey, in the vubsimilis. 
distinct transverse lines in the cell of the forewing and especially in the irregular transverse line of the 
hindwing, which is strongly incurved in cellule 2. Madagascar. 
H. angulifascia Btlr. is very similar to the preceding species, but has on the upper surface a larger angulifascia 
and more distinct eye-spot in cellule 2 of the hindwing and differs beneath in that the median line on both 
wings has a strong distad projection at vein 4 and at the costal margin of the forewing and on the hindwing 
throughout its entire length is distally bordered with light grey or grey-yellowish. Madagascar. 
H. parva Btlr. differs from the preceding in having the distal margin of the hindwing between veins parva. 
4 and 6 quite straight or slightly emarginate, so that a small angle is formed at vein 4. The wings above 
black-brown; the forewing with a small eye-spot in cellule 5 and a larger one in cellule 2, the ring of which 
is sometimes so thick and irregular that it forms a yellow spot; the hindwing with a small spot in cellule 2. 
The under surface is reddish brown with small brown striae and darker basal area; the median line of the 
forewing in cellule 2 deeply bent basal, passing round the yellow ring of the eye-spot; the median line of 
the hindwing projecting obtusely in cellule 4; the marginal area proximally lighter, more grey, at the distal 
margin darker again; the eye-spot in cellule 2 of the forewing large, that in cellule 2 of the hindwing small 
and without ring, all the others only represented by white dots. Madagascar. 
H. iboina W 'ard is above black-brown with the ey^-spots as in the preceding species; the distal margin iboina. 
of the hindwing is uniformly curved and undulate, just before it runs a thick, sharply prominent, blackish line; 
the distal margin of the forewing nearly straight. The under surface is brown-grey with the basal area darker 
and striated with blackish; the median line of the forewing is blackish, deeply bent in S-shape, and borders 
proximally the thick yellow ring of the eye-spot, in cellule 2; the median line of the hindwing is weakly in¬ 
curved between veins 2 and 4, but otherwise fairly straight; the eye-spot in cellule 2 of the hindwing is small 
and has a light yellow ring, other eye-spots are only indicated by white dots. Madagascar. 
H. difficilis Mab. only differs from iboina in having the median line of the forewing absent and that difficilis. 
of the hindwing strongly projecting distad at vein 4 and then deeply incurved (forming a semicircle) between 
veins 4 and 2; the eye-spots are larger than in iboina and the white dots surrounded by brown rings. Madagascar. 
H. vola Ward is black-brown above, the forewing with a large black, white-pupilled eye-spot bordered vola. 
with red-yellow in or somewhat before the middle of cellule 2 and a small spot in cellule 5; the hindwing 
with a small eye-spot in the middle of cellule 3. Both wings beneath are uniform blackish to the distal 
margin, but about 4 mm. from the margin are bisected by a broad, straight, sharply defined, common, whitish 
yellow transverse streak; the forewing has only one eye-spot, which is placed in cellule 2 just proximally to 
the transverse streak, and the hindwing only one small ocellus, placed in cellule 6 proximally to the trans¬ 
verse streak. In these markings on the under surface vola differs from all the other Ethiopian species of the 
genus. In the forests of North Madagascar. 
H. ankova Ward is smaller than the preceding species, only measuring 36—38 mm. Wings above ankova. 
black-brown; the forewing with a large, black, white-pupilled eye-spot with thick red-yellow border in cellule 
2 and a smaller similar spot in cellule 5; the hindwing above with two eye-spots of equal size in cellules 2 
and 3, and sometimes also a punctiform eye-spot in cellule 4. The under surface is grey, finely irrorated and 
striated with brown; the median line is rust-coloured and forms on both wings almost a right angle in cellule 
4; the eye-spot in cellule 2 of the forewing is surrounded by a thick, somewhat irregular orange-yellow ring; 
the other eye-spots are very small or only indicated by white dots. Madagascar. — ab. turbata Btlr. only turbata. 
differs in having the median line of the hindwing merely dentate, not sharply angled, and in the hindwing 
having three eye-spots beneath also. Madagascar. — cowani Btlr. (? 28 b) is probably also only a form of cowani. 
ankova, not differing except in having the basal area of the under surface much darker than the light grey 
distal area and in the hindwing having beneath distinct eye-spots in cellules 2, 3 and 6. Madagascar. 
4. Subgroup. 
The wings above in the middle, at least in the basal part of cellules 2 and 3 on the forewing and 3—5 on the 
hindwing, are for the most part red-brown to red-yellow. The forewing always with an eye-spot in cellule 2, placed beyond 
the middle of the cellule.
