[September 
of the cubital stem and gradually widens, ends on the inner 
margin between veins Cu 2 and 2A ; the white median band, 
which begins on the costal margin, becomes entirely blue 
where it joins the orange band. The under side is similar, 
except that the base of the wings is clothed with blue-grey 
scales, and the orange band of the hindwing is reduced to 
an elongate spot. Length of forewing, 23 mm. 
This species is similar to that described as Euerycina 
delphinia by Staudinger (L c.) . A male in the M. C. Z., 
from Macicore, Amazonas, which agrees very well with 
Staudinger’s description and figure, has the outer margin 
of the forewing slightly concave, whereas in barbouri it 
is somewhat convex; the tail of barbouri is relatively 
shorter, and the outer margin of the hindwing is more 
evenly rounded; the white band of the upper side of the 
forewing is more uniform and narrower in barbouri. On 
the under side, the subapical white shading of the fore- 
wing of delphinia is lacking in barbouri , and the white 
band of the hindwing is narrower, the orange spot larger, 
than in delphinia. The names calphurnia and vulnerata 
were based on females, in which the markings are quite 
different. 
Type, a male in the Museum of Comparative Zoology, 
from Barro Colorado Island, Canal Zone, 29. XI. 1934,
