EUNICA. 223 
The position of certain pencils of hairs on the wings, or their absence altogether, 
affords a ready method of dividing the numerous species of the genus into sections, 
and gives fairly natural results in grouping allied species together. Besides those 
pencils of hairs mentioned in the following arrangement, others exist in more southern 
members of the genus; so that the same system of subdivision can be carried out in 
regard to the whole of the species. | 
The neuration of the primaries is much like that of a number of closely allied genera, 
such as Myscelia, Epiphile, &c.; but sexual difference in the length of the terminal 
joint of the palpi serves to distinguish Hunica from any of these. 
In Eunica the subcostal nervure of the primaries gives off two branches before the 
end of the cell. In some species, such as E. pusilla, the median nervure is considerably 
swollen towards the base; and in these species the first median branch is thrown off at 
the distal end of the swollen part. In others, such as E. augusta, the median nervure 
is much less swollen, and the first branch thrown off much nearer the base of the 
nervure, the branch partaking of its slight swelling. The front legs of the male are 
slightly hairy; coxa > femur+trochanter ; tibia slightly < femur; tarsus (single- 
jointed) nearly=tibia. Middle and posterior legs spinous beneath ; claws short and 
much curved. Palpi rather stout; terminal joint in the male very short and ovate, in 
the female longer and more pyriform; middle joint in both sexes stout and slightly 
swollen. Antenne with 43 joints, the terminal 12 forming a slight club. The secon- 
dary male organs havea tegumen with a slender point hardly depressed ; the harpagones 
are elongated and narrow, without hooks or projections, slightly upturned at their 
distal ends, and hairy along the ventral surface near the end.

A single damaged female specimen is all we have yet received of this species, which 
doubtless cannot fail to be one of considerable beauty. The secondaries beneath, 
bearing a line of fulvous over the region of the median nervure, point to the relationship 
of E. mira with E. sophronisba and E. chlororhoa, both remarkable species in the genus. 
From analogy we believe the male will prove to have black wings, and the distal half 
of the secondaries rich blue or some other brilliant colour.
