Mabille has affixed the name argenteigutta, and to the original type of which in the Staudinger collection he has attached the name argentei-puncta. It is undoubtedly the female of the species named adosus by him. I know this because I have specimens of the two taken in coitu. 137. O. LUX, Holl. (Plate IV. figs. 23 S , 25 $ .) Osmodes lux, Holl. Ann. & Mag. Nat. Hist., Oct. 1892, p. 291. Hab. Valley of the Ogove. 138. O. STAUDINGEEI, sp. nov. (Plate III. fig. 20.) $ . Antennae, upperside of head, upper and lower side of thorax, and abdomen dark brown. The palpi on the underside are yellowish. The thorax on the upperside is clothed with a few obscure greenish scales. The primaries and secondaries on the upperside are dark brown. There are two bright yellow confluent spots on the cell near the end, three subapical spots which are situated in the usual place, and a series of spots extending from vein 1 to the subapical spots constituting a sharply defined macular band upon the disc. The lower spot of the series in interval 1 is subtriangular. The spot in interval 2 is elongated, subquadrate, and the largest of the series. The spot in interval 3 is the same form as the spot in interval 2 but smaller. The spots in intervals 4 and 5 are minute, elongated. The lower subapical spot is larger and elongated. The two upper subapical spots are small. In the secondaries there is a small circular yellow spot at the end of the cell, and beyond it an irregularly curved series of five discal spots likewise bright yellow. On the underside the primaries and secondaries are more obscure in colour than on the upperside, the spots and markings being, however, identical in form and position. Expanse 30 m m. Hab. Valley of the Ogove. Type in m y collection. I do not know the male of this species. The solitary female in my collection is, however, so totally distinct from every other species known to m e that I do not hesitate to describe it as a new form. 139. O. BANG-HAASII, sp. nov. (Plate IV. fig. 9.) 3. Antennae black. Upperside of palpi, head, thorax, and abdomen rufous-brown. Lower side of the palpi, thorax, and abdomen of the same colour, somewhat more obscure. The primaries on the upperside have the ground-colour bright rufous. The apex, the outer margin, and the outer half of the inner margin are broadly deep black. Beyond the end of the cell there is a broad irregular black spot. The costal margin and the base of the wino-as far as the middle of the cell are fulvous, shading outwardly about the middle of the wing into blackish. The secondaries are |
