abdominal edge. Beneath, the same, but the white spots 
are so much larger that the basal half of the wing might 
be described as white, with a number of quadrate black 
spots. All the wings with a very narrow white fringe in 
the sinuses. 
Body above, dark brown, with a few white spots ; be- 
neath white. Antenne ringed black and white, club 
black. 
One example, Montes Aureos, Maranham. 
[The following is a list of the species of Cremna, so far 
as at present known; the genus is a very distinct one, 
and is separated from Charis and allies by havmg four 
branches to the subcostal nervure of the fore-wing. 
1. Oremna Ceneus, Cramer, Pap. 156 F. 
Surinam, Amazons, Maranham, 
2. Oremna hetercea, n. sp. 
& . Expanse 1” 4’, Very similar to C. Ceneus ; costa 
of fore-wing arched, apex much less produced, and more 
obtuse. Fore-wing dark brown, crossed by six broadish 
interrupted belts of a glossy light blue, the one nearest 
the outer margin lunulated ; along the apical half of the 
costa are a number of small white spots, besides a row 
along the outer margin ; beneath, paler, the belts much 
more broken up, and consisting of irregular rows of white 
spots, some of them oblong. Hind-wing above, crossed 
by five belts, broader and less interrupted than those of 
the anterior wing, except the middle one, which is divided 
into squarish spots, forming almost a double belt; the 
submarginal belt is lunulated, and very broad ; near the 
outer margin is a row of white specks; beneath, the 
same, but the belts white, and broken up into spots, as 
in C. Ceneus. 
Ega and Tunantins, Upper Amazons. 
This seems to be an incipient species, scarcely segre- 
gated from C. Ceneus, the type form of which is also 
found at Hga. 
3. Cremna Beltiana, Bates, ante, p. 541. 
Montes Aureos, Maranham.
