530 PROF, J. O. WESTWOOD ON THE URANIID&. 
apical margin of the wing is marked with two very slender pale lines, which unite 
together about half the distance from the apical angle. The first of these lines is 
angulated near the angle; and the outer one is scalloped. ‘The rich purple oval spot 
occupying the whole of the outer angle, and a great portion of the disk of the wing, 
terminates in a narrow flesh-coloured line extending to the anal angle, from which 
upwards the anal margin of the wing is marked with several short, obscure, transverse 
marks, whilst between the anal angle and the tail there are three rather large semioval 
black spots. 
On the underside of the Columbian specimen the fore wings are uniform brown, the 
basal third portion as far as the vein closing the discoidal cell being luteous; the 
costa is narrowly luteous with three small black dots between the end of the cell and 
the pale fascia, and six similar dots between the fascia and apical mark. A fascia of 
clear, pale buffish white occupies the place of the band of the upperside, with both its 
margins slightly scalloped or waved at the veins; the apical margin is pale luteous 
buff, dilated a little at the apex, and marked with very minute black transverse lines ; 
this pale border vanishes between the first and second median branches. The hind 
wings have the basal half luteous and the apical half brown, the former colour extending 
to within two lines of the anal angle. In the Columbian specimen the pale basal 
portion terminates in a slight curve, the middle of which is towards the base of the 
wing ; it is not defined by a distinct paler streak; and the longitudinal veins in the 
middle of the wing are marked with three or four small luteo-fulvous spots on each. 
The apical margin of the hind wings is narrowly luteous buff between the tail and 
outer angle, and bears a somewhat triangular spot between the tail and anal angle. 
There is considerable difference between the two specimens in the Hopeian Collection. 
The Columbian one is more elegant in its form, the fore wings of the Papagayan 
individual are more ovate, and the hind wings shorter. The dark central portion of 
the fore wings is relatively very much broader in the Columbian specimen, in which the 
costal margin of the fore wing is unspotted beyond the middle, whereas it bears four 
pale dots in the other ; the blue patch on the hind wings is of a whiter blue in the 
Papagayan specimen, and the pale basal portion of the hind wings terminates in a 
narrow waved paler fascia preceded by a darker and more distinct waved line, this pale 
fascia slightly curving outwards in the middle, whilst the pale fascia of the fore wings 
on the underside is nearly straight and rather broader than in the other.
