Egocera Boisduvalii, Lat. (1).—A West African species. 
Ah. rectilinea, Bdv. (8). a 
Xanthopsilopteryx Kirbyi, sp. nov. (1).—Male (fig. 2). Expanse 
of wings, 65 mm. Head and thorax black. Head with two 
white spots before, and two behind antenne; thorax with a 
row of four white spots in front, 
and three across centre. Abdo- 
men yellow, banded with black, 
and a large black anal tuft. Fore- 
wings black; near the base a row 
of four small white spots below 
the costa, and three yellow spots. 
Beyond these, two yellow spots ; Ab 
one near the costa, semicircular, ge I RN. 
convex towards the base, one aU AapSIIpIe ELT 
touching the inner margin, triangular. Beyond these, a row of 
three yellow spots; one near the costa, semicircular, convex 
towards the apex, the central larger and quadrate, the third 
near (but not touching) the anal angle, small and triangular. 
Beyond these, a large subapical transverse yellow spot of 
flattened elliptical shape. Tip of wings white. Hind-wings 
brilliant orange, with black border, narrowest at anal angle, 
broadening and then narrowing again along hind margin, 
broadest at apex, which is tipped with white. 
The species of this brilliant genus are very similar in 
general aspect, but the markings appear to be very constant, 
and thanks to the British Museum Collection, and Mr. W. 
F. Kirby’s Monograph of the group (Trans. Ent. Soc., 1891), 
the present species (which I have much pleasure in dedicating 
to that naturalist) could be separated from its allies. It is 
nearly related to X. superba, Butl., but the size is smaller, 
the fore-wings proportionally much narrower, and the sub- 
apical spot smaller and narrower. From X. eva, Mab., X. 
indecisa, Wlk., and X. africana, Butl., it may be separated by 
its inner yellow band broken into two spots, those species 
having the band entire. In X. wanthopyga, Mab., the second
