*. Under surface of hindwing without deep black dots or spots. 
f. Hindwing above at the anal angle with a white spot and white fringes, beneath behind the middle 
between the costal margin and vein 1 b with a narrow white transverse band. A small white 
spot or transverse streak at the end of the discal cell on both wings. Rh. ramanatek, 
ff. Hindwing above without the white spot at the anal angle. 
§. Body above and the wings at least in the basal parts scaled green or blue. Fringes of hindwings 
coloured dark. The white spot of the hindwing beneath of a moderate size, only occupying 
about half the width of the wing. Palpi marked white and black. 
1. The white spot of the hindwing beneath is situate at the costal margin. Rh. chalybe. 
2. The white spot of the hindwing beneath is situate about the centre of the wing between 
the veins 1 b and 6. Rh. bixae. 
§§. Fringes of hindwings at the anal angle yellow or reddish-yellow. The white area of the 
hindwing beneath is very large and, between the costal margin and vein 1 b, it forms a 
posteriorly very much tapering transverse band. 
1. Hindwing beneath without a white spot at the proximal margin in area 1 b. Hindwing 
above as far as beyond the centre with bright reddish-yellow hair. Rh. fetvida. 
2. Hindwing beneath at the proximal margin in area 1 b with a separate white or whitish 
spot. Rh. forestan, 
**. Under surface of hindwing with one or several rounded jet-black dots. 
f. Hindwing beneath with but one large black dot situate about the centre of area 1 c. 
1. Wings above almost black, at the base broadly haired greenish-blue. The white spot of the 
hindwdng beneath begins at the costal margin and reaches to vein 1 b, but it tapers off very 
much behind. A small white antemarginal spot in 1 c. Fringes of hindwings dark, only below 
at the anal angle yellowish. Rh. pansa. 
2. Wings above grey or blackish-grey without blue scales. The white spot of the hindwing beneath 
does not reach to the costal margin and is sometimes broken up into spots, but invariably 
broadest in area 1 c. A yellow antemarginal spot in 1 c. Fringes of hindwing white, at the 
anal angle yellowish. 
a. The white transverse band of the hindwing beneath is complete. Rh. anchises. 
b. The light transverse band of the hindwing beneath is broken up into spots. The spots 
are sometimes orange-yellow instead of white. Rh. jucunda, 
ft. Hindwing beneath with 2 to 5 black dots, those in 1 c sometimes being combined and forming 
a transverse streak, but always situate behind the centre of this area. The light transverse band 
of the hindwing beneath always begins at the costal margin and at least reaches to vein 1 h. 
Fringes of hindwing in the anal part always orange. 
1. The transverse band of the hindwing beneath is snow-white. Hindwing above at the base 
and in the centre lighter yellow, at the margin broadly blackish. Hindwing beneath with 
one black dot each in 2 and 3, and in 1 c with a black transverse streak or with 2 contiguous 
black dots. 
a. Hindwing beneath without a black dot in area 4. The black transverse streak in area 
1 c is also towards the margin bordered with white. Rh. pisistratus. 
b. Hindwdng beneath also in area 4 with a black dot; its black transverse streak in area 1 c 
is towards the margin bordered by an orange spot. Rh. hanno. 
2. The transverse band of the hindwdng beneath is light yellow^. , 
a. Wings above monotonously grey, scarcely darker at the margin. Hindwing beneath with 
one black dot each in 2 to 4, and with two black dots in 1 c forming a transverse streak. 
Rh. necho. 
b. Hindwing above at the base and at the proximal margin broadly haired orange, at the 
margin broadly black, beneath only in area 2 with a black dot, and in 1 c with a black 
transverse streak which is bordered with orange towards the margin. IIh. sejuncta. 
[5. Hindwing beneath without a wdrite or whitish spot or transverse band. 
*. Hindwing beneath in the centre of area 1 c with a rounded jet-black spot in an orange area.
