H. narcissus is distinguished by having both wings above more or less extended red-yellow in the 
middle, but bordered all round with black-brown; the red-yellow discal area of the forewing is divided by a 
brown transverse line into a darker proximal and a lighter distal part, in which latter is placed the eye-spot 
of cellule 2; the hindwing has on the upperside two eye-spots in cellules 2 and 3. — narcissus F. (28 c). 
The black-brown hindmarginal stripe on the forewing above is about two mm. in breadth and sharply de¬ 
fined; the yellow discal area covers cellules 2 and 3 (except at the distal margin) and forms a narrow stripe 
at the hindmargin of the cell and along the posterior side of vein 2; on the hindwing only the basal part of 
cellules (2) 3—5 is more or less broadly yellow; on the under surface the black, white-pupilled eye-spot of 
cellule 2 is placed in a thick yellow ring, but has no outer reddish ring; the median line on the underside 
of the hindwing is very irregularly lobed and incised. Mauritius and Bourbon. The eggs are light yellow 
and are spherical with shallow pitting. The larva lives on bamboo and when full-grown is light reddish-brown 
mixed with greenish and with darker head; the chain-like dorsal line is anteriorly greenish, posteriorly brown: 
the undulate subdorsal line and straight lateral line are light-brown; spiracles black; the body bears very 
short, fine hairs. The pupa is of the normal Satyrid shape and is green with some straight black streaks at 
the anterior end. — fraterna Btlr. (28b) is the form occurring on Madagascar and only differs in having the 
eye-spot in cellule 2 of the forewing beneath surrounded first by a yellow and then by a red-brown, posteri¬ 
orly much thickened ring and the median line on the hindwing beneath nearly even, only slightly sinuous; the 
eye-spots on the underside of the hindwing are sometimes well developed, sometimes only punctiform or 
absent. — maeva Mab. only differs from fraterna in having the yellow colour on the upperside of both wings 
much more extended; on the fore wing it nearly reaches the hindmargin, which is only narrowly and in¬ 
distinctly brown, and covers almost the whole of the cell; on the hindwing it extends into cellule lc and 
the cell. Madagascar. 
H. menamena Mab. The forewing above orange-yellow, at the base brownish yellow, the apex rather 
broadly and the distal margin more narrowly black-brown, in cellule 2 close to the distal margin a small, black, 
white-pupilled eye-spot bordered with light yellow; the hindwing above entirely orange-vellow. only at the 
base somewhat brown and at the distal margin with a brownish transverse line; close to this are placed 5 
or 6 white clots, surrounded by a fine brown, a yellow, and quite outside again by a fine brown ring. Both 
wings beneath pure orange-yellow without striation, but with three yellow-brown or somewhat reddish transverse 
lines, of which the inner two are almost straight and the third is placed near to the eye-spots and curved or 
undulate; the forewing has eye-spots in lb, 2, 4 and 5 and the hindwing seven, of which those in cellules 2 
and 3 are a little larger. Madagascar. 
H. ankaratra Ward (28 c). Both wings above red-brown, costal and distal margins narrowly black- 
brown (about 2 mm. in breadth); each wing with two black, white-pupilled eye-spots; those on the forewing 
in cellules 2 and 5, on the hindwing in 2 and 3. Forewing beneath in the posterior half red-brown to the 
middle of the cell and to vein 3 or 4, otherwise dark grey, with blackish transverse striae; hindwing beneath 
black-grey with dense blackish transverse striae; the eye-spots on the under surface with yellow rings, the 
hindwing beneath with seven eye-spots, of which only those in cellules 2 and 3 are somewhat larger and 
stand out sharply. Madagascar. 
Second Group. 
The wings above with an eye-spot at least in cellule 2 of the forewing. Distal margin of the hindwing with 2 or 
3 teeth or small, short tails at the extremities of veins 2, 3 and 4. 
H. masoura Mew. is a very distinct and aberrant species. Both wings above and beneath white; the 
forewing suffused with yellowish at the end of the cell; its costal margin and apex above very narrowly black: 
beneath with black transverse striation, above in cellule 2 beyond the middle with a small blackish ring with 
dark central dot; distal margin of the forewing strongly and irregularly undulate. The hindwing at the 
extremity of veins 2 to 4 with very sharp teeth or small, short tails, of almost uniform length, beneath at the 
base and the inner margin striated with black and with 6 black, white-pupilled eye-spots, two in cellule 1 c 
and one each in cellules 2, 4, 5 and 6; the last three placed in a line at almost a right angle with the rest. 
Interior of Madagascar. 60—75 mm. 
H. benacus Mab. Distal margin of the forewing undulate, of the hindwing shortly toothed at the 
extremities of veins 2—4. The wings above with a light grey-yellow ground-colour; the forewing at the costal 
margin, the apex, the distal and inner margins blackish in almost exactly the same width as in narcissus, the 
light discal area also as in narcissus devided by a dark transverse line into an inner, slightly darker part, 
which reaches the base, and an outer part in which is placed the black, white-pupilled eye-spot. The hind-
