432 MR. A.G. BUTLER ON NEW DIURNAL LEPIDOPTERA. [May 9, 
with brown on its outer edge. Posterior wing white; nervures 
black. 
Underside—anterior wing silky white; nervures yellow. Poste- 
rior wing silky white; nervures yellow at their outer extremities, 
black at the base. 
Female. Upperside—anterior wing white, yellowish at the base 
and anterior margin ; a broad orange apical band reaching along the 
outer margin nearly to the third median nervule, bordered on its 
outer edge by a brown band, and enclosing six brown spots, the two 
lowest ones being connected to one another and to the margin, and 
intersecting the orange band ; a few brown scales on the interior 
margin of the orange band; an indistinct brown spot near the anal 
angle ; a black spot at the end of the cell. Posterior wing white ; 
five brown spots at the outer extremities of the nervules. 
Underside—anterior wing white, yellowish at the base and anterior 
margin; a broad salmon-coloured apical band reaching along the 
outer margin, nearly to the third median nervule, and enclosing six 
brown spots; a black spot at the end of the cell. Posterior wing 
pale salmon-colour ; a row of four lunular brown spots crossing the 
wing obliquely from the anterior margin, a little beyond the middle, 
and joining at an angle two similar brown spots running parallel to 
the outer margin; a small brown spot on the inner side of the sub- 
median nervure at two-thirds of its length from the base. 
Hab. White Nile. 
Closely allied to A. tone (Port Natal), but much less robust ; the 
violet apical band of the male and the orange band of the female 
much broader and fuller, and not enclosed in brown as in J. tone, 
the inner black margin being almost indistinguishable. The male 
without the black spots in the anterior wing, or the black termina- 
tions to the nervules of the posterior wings ; all the other markings 
are also much less distinct, and the whole insect is much smaller.

Male. Upperside bright yellow; all the wings with hind margins 
deeply sinuated ; cilia (except at anal angle), front of the head, and 
base of the antennez crimson; the remainder of the antenne brown 
above and white beneath, with orange tips; thorax greenish grey; 
abdomen yellow. Anterior wing—apex and hind margin brown, with 
orange inner margin, the inner side deeply sinuated and dentated ; 
a curved orange band at the end of the cell, and a band of orange 
spots crossing the wing a little beyond the middle, and connecting 
the apical band with the anterior margin. Posterior wing with very 
narrow chocolate-brown hind margin; orange on its inner side. 
Underside—anterior wing pale yellow; apical band dark brown 
on its inner and light brown on its outer side, enclosing an almost 
triangular metallic-violet dash, the base of which touches the ante- 
rior margin ; the band at the end of the cell only marked by a red- 
dish outline; base of the wing reddish ; a red spot at the outer ter- 
mination of the costal nervure and the first subcostal nervule ; a faint 
silver spot at the end of the cell. Posterior wing pale yellow; an
