vein to the base of vein 3; hindwing beneath without a light band from the costal margin; fringes of hindwing

I. imperialis Plotz is not figured by Plotz, nor has it apparently been found again; Watson does imperialis.

Above dark blue with black veins, with an oval light greenish-blue discal spot and behind it a semicircle of 
similarly coloured broad rays between the veins; ventrum and palpi orange. 
I. hemixanthus Rothsch. is a magnificent species from the Aroa River, exhibiting the approximate hemixan - 
colouring of P. rudolphi (174 e), with a straw-coloured anal half of the hindwing. On the forewing between thus 
the cell and hind-margin pale yellowish-red, veins bluish-black. 
5. Genus; l&iiopsilocaiiipta Wallgr. 
The genus is predominantly African and most of the species are figured in Vol. XIII, on pi. 73. They 
have like the preceding ones stout bodies and extraordinarily large heads, with mostly nocturnal habits. 
The anal portion of the hindwing is particularly very much extended. The antenna, like that of Ismene, begins 
to form a thick club already soon after the middle, slowly swelling up and then gradually decreasing again. 
On the hindwing vein 5 is absent or it is very feeble; the median branch rises before the last quarter of the 
lower cell-wall. The larvae are stouter than those of Ismene ; they are just as variegated, but they exhibit 
at the vertex a slight depression of the head which in Ismene forms an almost uniformly round disc. The face 
is marked with black as in Ismene. Probably all the forms of this genus described from the Indo-Australian 
Region belong to one species.

covered with a bright blue gloss, beneath not only the anal region of the hindwing, but more than half of the 
hindwing is yellow, being proximad more reddish-orange and distally more yolk-coloured. — onnatus Rothsch. omatus. 
(171 e) comes from New Guinea, Rapaur, and the Aroa River. It differs in exhibiting deeper red palpi and the 
more truncate shape of the orange-red anal area of the hindwing beneath. 
III. Subfamily: PampbiSinae. 
This subfamily contains more than 200 genera with a very great number of forms, most of which, however, 
are confined to America. They were divided into two sections by Watson, a smaller one containing about 
50 genera, to which the largest palearctic species belong, such as Erionota thrax and Gangara thyrsis. They 
group together around the proper genus Pamphila ( - Steropes Bsd., Carterocephalus Led.). 
1. Genus : Motasingiisi Wts. 
Exclusively Australian. The few species in life almost look like species of Parnara, but they exhibit 
very large distinct spots on the fore wing. Anten n ae more than half the length of the costa, club short, 
fusiform, rather thick with a fine point which is reverted in a flat bow. In the forewing the lower radial branch,

**) In his Catal. Insect. Japon. Matsumura expressly states the Hokkaido as patria, whereas in the (recent) table 
of the Japanese Hesperidae (Entomol. Zeitschr. Stuttgart Yol. 23, p. 217) he omits the species in the northern island.
