672 MR. A. G. BUTLER ON SIX NEW BUTTERFLIES. [Nov. 14, 
considerably beneath in the arrangement of the black spots on all 
the wings, in the further extension of the red patch of the lower 
wings, and the more brilliant colouring ; above in the presence of a 
subapical orange band and different disposition of the green patches 
in the fore wing and the narrower black bordering to the hind wing. 
6. RomMALEOSOMA AGNES. 
Upperside—front wings rich chocolate-brown, crossed beyond the 
middle by an irregular orange or white band ; apex white ; a violet 
patch on the inner margin beyond the middle. Hind wings choco- 
late-brown, with a central curved band of violet; inner margin pale 
brown. 
Underside—front wings greenish or brownish olivaceous, crossed 
beyond the middle by an irregular white band; a submarginal row 
of seven very ill-defined greyish spots near the hind margin ; apex 
white ; nervures and extreme edges of wings ochreous ; three small 
black spots within the cell. Hind wings the same as the front wings, 
but with a much narrower central white band, bounded below by the 
first median nervule. 
Hab. Ashantee. 
This species, from the similarity of the underside-markings, has 
been confused with R. medon of Linnzeus, but I feel certain that it 
is distinct. It differs from R. medon in being shorter in the wings, 
less robust, the ground-colour of the underside uniform greenish or 
brownish olivaceous, the black spots much larger, and the bands 
longer. The upperside is quite different. It is figured in Drury’s 
‘Illustrations of Natural History,’ ii. pl. 15. 
The description given by Linnzeus of R. medon is so insufficient 
that, without Clerck’s figure, it would suit about two-thirds of the 
insects in the genus; and as there have been several mistakes made 
concerning it, I give a fuller description of it below. Cramer has 
figured a variety of R. ceres as R. medon (pl. 205. f. C, D). 
7. RoMALEOSOMA MEDON, Linn. (Fig. 6, p. 673.) 
Female. Upperside—front wings rich chocolate-brown, glossed 
with steel-blue ; crossed beyond the middle by an irregular chrome- 
yellow band, narrower above than below, extending from just beyond 
the middle of the anterior to just beyond the middle of the outer 
margin ; apex white; interior margin silvery blue-green ; front mar- 
ginal edge irrorated with orange. Hind wings steel-blue, changing 
to silvery blue-green beyond the cell ; outer and inner margins cho- 
colate-brown glossed with purple. Body brown; antennz with 
orange club ; palpi orange. 
Underside—front wings pale greenish, varied with dull chocolate- 
brown, crossed beyond the middle by an irregular white band, nar- 
rower above than below, extending from just beyond the middle of 
the anterior margin to near the outer margin just beyond the middle, 
and interrupting a submarginal band of ill-defined brown spots ex- 
tending from the anterior margin near the apex to the interior mar- 
gin near the anal angle; apex white, cilia and basal half of front
