Show 46 DR. W. J. HOLLAND ON THE AFRICAN [Jan. 14, The type of icteria is before me as I write. It is strictly congeneric with morantii, Trim. • 145. P. HARONA, Westw. Pamphila harona, Westw. App. Oates's Matabeleland, p. 353 (1881); Trim. P. Z. S. 1894, p. 74. Hab. Manica-land (Trimen) ; Falls of the Zambezi ( Westivood). OSPHANTES, gen. nov. Antennae moderately long, slender; club gradually enlarging and terminating in a fine point, the terminal portion being recurved. The palpi are short, appressed, suberect, the first joint short, the second long, both densely covered with thick scales. The third joint is minute, conical. The hind tibiae are armed with a double pair of spurs. The primaries have the inner margin strongly angulated about the middle and clothed with along bundle of hairs on the elongated portion of the hind margin, which is as long as the outer margin. Vein 5 nearer 4 than 6. Vein 12 terminating on the costa before the end of the cell. The cell more than half the length of the costa. The secondaries have the neuration as in Osmodes. On the lower edge of the cell and about the origin of veins 2 and 3, the cell of the secondaries is naked, marked by an opaque tract, suboval in form, having a glazed appearance. Immediately behind this naked glazed tract is a pocket-like depression on the upperside lying between vein 1 b and the lower margin of the cell near the base. The primaries on the underside have the basal portion almost naked tow7ard the base, covered with shining closely appressed scales. - Type 0. ogoivena, Mab. I was inclined originally to refer this peculiar species to Osmodes, to which it is allied, but the very peculiar structure of the hind wing shows such a great divergence from the typical species of Osmodes that I feel constrained to erect a new genus for its reception. Furthermore, the coloration of the insect differs in many important particulars from that of typical Osmodes. The figure of the insect given in the 'Novitates' by Mabille is sufficiently characteristic, though the spots on the underside are not delineated as they are in the examples before me. They recall somewhat in the specimens I have the maculation of Padraona zeno, Trim. 146. O. OGOWENA, Mab. Plastingia ogowena, Mab. C. R. Soc. Ent. Belg. 1891, p. exxi; Novit. Lepidopt. p. 94, pi. xiii. fig. 5. Hab. Valley of the Ogove. This species was evidently placed by Mons. Mabille with doubt in the genus Plastingia, in which he has put a number of other African species. The type of Plastingia is flavescens, Feld., with which this species has but little in common, save the general stvle of coloration. It does not agree with any other African species |
