spot at posterior angle ; of hind-wing whitish, more or less blackish at 
origin. Under side. — White, with black strice-and spots; pattern as 
in Bosimon and Hintza, but nearer Rosimon. For e- wing : subcostal 
stripe ending abruptly in a spot on costa before end of cell ; stria from 
inner margin more regular ; stria closing cell straighter ; spots of 
transverse row beyond middle confluent (the third forming an elongate 
projection towards hind-margin), — the sixth and seventh widely dis- 
joined from the rest, and forming a stria in a line with, and almost 
touching, that closing cell ; two submarginal rows of spots, — the inner 
linear a little below costa, but thence of large quadrate spots (the 
second touching fifth of row beyond middle), — the outer of rounded 
spots ; a black edging line. Hind-iuing : at base a spot {not a stripe), 
followed by a transverse row of four spots ; other markings very 
much as in fore-wing, except row beyond middle, which is inter- 
rupted as on upper side ; four to six spots of outer submarginal row 
marked with bluish- silvery. Tail of hind- wing long, black, white- 
tipped. 
The $ and ^ of this species are alike, except that in the $ the 
black is more intense, and also rather broader, so that the white discal 
spaces are more restricted. On the under side of fore-wing it some- 
times happens that the projection from transverse row beyond middle 
joins the spot commencing inner submarginal row, so that a quadrate 
white spot is isolated on costa. The entire absence of any basal blue 
readily distinguishes Melxna from Rosimon and from Hintza ^ ; but it 
is by no means so easy to separate it from Calice, Hopff., with which I 
for many years associated it. On the upper side there is scarcely any 
difference, but Melcena constantly presents in the fore-wing a discal 
white area almost divided transversely hy the approximation of the 
terminal disco-cellular mark and the lower portion of the irregidar discal 
row, the latter heing almost in a straight line heneath the former. This 
difference is also very marked on the under side, the two markings in 
question forming in some specimens an almost continuous stripe, 
whereas in Calice the lower portion of the discal streak is almost con- 
tinuous of the upper, and so remote from the terminal disco-cellular 
streak. The principal under-side markings in Ifelmna are thicker than 
in Calice, with the exception of the lower spots of the discal series in 
the hind-wing ; four at least of the hind-marginal black spots of the 
hind- wing are marked with bluish-silvery ; the ground is of a purer 
white without any slight tinge of yellowish ; the submarginal macular 
series in the fore-wing forms a continuous streak (very attenuated be- 
tween upper radial and third median nervule), and in the hind-wing 
an almost continuous one ; and the cilia of the hind-wing are without 
fuscous interruptions. 
I found this species not common in Natal in 1867 ; it frequented wooded 
spots, and was fond of settling on the upper leaves and twigs of bushes. I 
observed it on the wing from the beginning of February to the beginning of
