204 Mr. H. W. Bates on the Nymphalinse 
are above of a tawny-ochreous hue, with a faint-brown belt near the 
apex of the fore wings, and a black speck on the hind wings. 2. 
Next to these are individuals having the apex of fore wings much 
darker (Agatha, F.). 3. Then follow others similar to the last, but 
with a darkish border to the hind wings, preceded by a dusky waved 
line (Ariadne, Cram.; Merione, F.). 4. A further variety is similar 
to this last, but has the apex of fore wings rufous, preceded by a broad 
blue-black belt. 5. A more extreme form is of a glossy tawny- 
orange colour, with fore wings marked like the last, but with the 
hind wings having the apical two-thirds of a rich blue-black colour 
(Merione, Hiibn. pt.). 6. The furthest limit of variation in respect 
of darkness of colour is reached in P. Laothoé of Cramer, which has 
the hind wings wholly dusky black. I have a 2 specimen from 
Demerara similar to Cramer’s figure of Laothoé, except that the black 
apex of the fore wings has, in the middle, a large whitish spot, and the 
basal portion of the hind wings is fulvous. The wings are of the same 
shape in all these varieties, except that the hind wings vary in rela- 
tive length ; beneath they all have the same characteristic markings, 
but differ in the clearness of the design and intensity of hue. 
None of these varieties are, strictly speaking, local modifications or 
races, for in all localities two or more of them are seen flying toge- 
ther; but this much may be said, that the handsome dark variety, 
no. 5, occurred only in the interior of the country on the Upper 
Amazons, mingled, however, with no. 4; whilst the palest varieties, 
1 and 2, were found only on the Lower Amazons. Nos. 1 and 4 fly 
together in some parts of this latter region, and no. 2 occurs in New 
Granada. 
Genus Nica (Hiibn.), Felder, Kin neues Lepid. p. 16. 
The only character which distinguishes Vica from Temenis is the 
peculiar pattern of the under surface of the wings, which shows a 
nearer affinity to the following genus, Pelia. The neuration, shape 
of antenne and palpi are nearly the same as in Temenis; but the 
facies of the two or three closely allied species which form the genus 
reveals no very close relationship to any of the preceding, and seems 
sufficient to warrant their generic separation.

Expanse 1" 10'", ¢ 2. Very similar in size and general colour to NV. 
Flavilla (Godt.) of South Brazil. Fore wings obtusely pointed, outer 
margin scarcely incurved in the @, straight in the 9: above rich tawny, 
with a dusky streak across the end of the cell; the apex has a broad deep-
