6 RHOPALOCERA. 
Doubleday placed the genus in the family Heliconiide; but this view is no longer 
tenable, as Mr. Bates’s researches have proved (Trans. Linn. Soc. xxiii. p. 517). 
The genus is a purely neotropical one. The Central-American representative has a 
wide range over the northern parts of South America. The definition of the members 
of the genus is by no means well marked, and some of the species may prove to be of 
merely nominal value.

Though subject to slight variation, the members of this species found in particular 
districts are not, in our opinion, separable as distinct races. In specimens from 
Eastern Peru, the yellow spots. at the apical half of the anterior wing are reduced to 
five small ones (four of which constitute the subterminal row), and a narrow fulvous 
line between the first and second median branches. The normal yellow spot at 
the extremity of the cell is fulvous; and the lower band on the posterior wings is 
obsolete towards its inner end. 
These specimens show the most abnormal coloration of our series ; but others approach 
them, the chief variation consisting in the yellow spots between the second and third 
branches of the median nervure of the anterior wings being confluent or not. 
Its nearest ally appears to be L. halia, Hiibn., of Brazil, of which it is a northern race, 
the two being found together at Maranham. Another close ally, L. cleobwa (Gdt.), 
occurs in the island of Haiti. The Guiana forms, L. pasinuntia (Cr.) and L. ceres 
(Cr.), differ rather more decidedly in the distribution of the yellow markings of the 
anterior wings. 
Group ITHOMIINA. 
Males without anal tufts; basal joint of palpi long; front leg of female not club- 
shaped; secondary wings with one or more tufts of hair near the subcostal nervure *, 
* These tufts are usually only present in the male; but in Methona they exist in both sexes.
