Show 64 DR. W. J. HOLLAND ON THE AFRICAN [Jan. 14, position, and below and beyond the cell two discal spots, subquadrate in form, on either side of vein 3 near its origin. The lower of these ,spots is the larger. They are both translucent and waxy yellow in colour. There are two small obscure semi-transparent spots of like colour on the secondaries on either side of vein 3 a little beyond its origin. The margin is slightly darker brown than the body of the wing, and the fringes are paler. On the underside the wings are uniformly pale reddish ochraceous, except the inner margin of the primaries, which is darker, inclining to plumbeous. The spots of the upper surface reappear on the lower side, but far less distinctly defined. Expanse 30 m m . Hab. Valley of the Ogove. This very distinct species is represented in m y coUection by a single specimen. 218. P. (?) URSULA, sp. nov. (Plate II. fig. 4.) 3 . This insect is obscurely brown all over, without any spots or markings whatever. 2 . The female is coloured like the male, but has three elongated subapical spots in the usual position, and two obscure translucent spots on either side of vein 3 of the primaries a little before its origin. The spots are subquadrate. Expanse, 3 26 mm., 2 30 m m . Hab. East Africa. The types of the males are found in m y collection and in the collection of Dr. Staudinger. The only female I have ever seen is contained in the collection of Dr. Staudinger. I refer this insect with some measure of doubt to the genus Parnara, with which it in the main agrees in neuration as far as I have been able to ascertain. The insect, however, is not so robust as the other species referred to this genus. The primaries are more rounded on the outer margin and the secondaries somewhat more excavated before the anal angle, in the case of the female. I cannot, however, with the material before me, venture to separate this species from the genus Parnara. SEMALEA, gen. nov. Antennae and palpi as in the genus Baoris. Primaries: cell about half the length of the wing; vein 5 much nearer 4 than 6 ; vein 12 terminating on the costa before the end of the cell; vein 7 slightly before the end of the cell; vein 2 one-third of the distance from the base ; vein 3 a little before the end of the cell. Secondaries : cell short ; vein 5 wanting ; discocellulars faint, erect; vein 7 originating well before the end of the cell; vein 3 a little before the end of the cell ; vein 2 originating beyond the middle of the cell; the outer margin evenly rounded; the costa slightly produced before the base. The two species referred to this genus are characterized by peculiar sexual markings. In the case of the male of S. pulvina, Ploetz, the type of the genus, there |
