A NEW RIODINID FROM PANAMA (LEPIDOPTERA) 
By Marston Bates 
Museum of Comparative Zoology, Cambridge, Mass. 
Genus Rodinia Westwood 
This generic name was proposed by Westwood (1851, 
Gen. diurn. Lep., II, p. 430) for a number of species, in- 
cluding Erycina calphurnia Saunders (1849, Trans, ent. 
Soc. London (1), 5, p. 216), which was designated as the 
genotype by Stichel (1909, Berl. ent. Zeits., 54, p. 42), 
although Saunders had proposed the name Euerycina for 
his species in 1859 (Trans, ent. Soc. London, (2), 5, p. 
95), and restricted Rodinia to the other species listed by 
Westwood (1. c.) . SticheTs action seems to be entirely in 
accordance with the provisions of the International Code 
of Nomenclature, even though it is not in strict accordance 
with the historical usage of the names involved. 
Three “species” have been described in the genus: 
Erycina calphurnia Saunders (1849, l. c.) ; Euerycina 
delphinia Staudinger and Schatz (1888, Ex. Schmet., I, 
p. 248, pi. 89) and Rodinia ( Euerycina ) vulnerata Rober 
(1923, Stett. ent. Zeit., 84, p. 94). All were based on Ama- 
zonian material, and as only a few specimens are known, 
the status of these names is uncertain. The discovery of 
a related form in the rain forest of Panama is surprising. 
Rodinia barbouri sp. n. 
$ . The ground color is dark grey ; the upper side of 
the forewing has a straight, white, lavender-bordered, 
median band, which does not quite reach the costal margin, 
and ends on the outer third of the inner margin ; the lower 
two thirds of the outer margin is bordered by blue. The 
outer margin of the hindwing is completely margined by 
blue, and the tail is entirely blue except for an apical fringe 
of white scales. An orange band, which begins at the base
