Show 1879.] MR. W. L. DISTANT ON AFRICAN LEPIDOPTERA. 705 some distance apart near tbe centre ; beneath cell, and a little base of lower median nervule, is situated a black ring. Hind wings with two black spots near base, between costal nervure and first subcostal nervule, and an 8-shaped black mark on basal half of cell. Exp. wings 3 ^ inches. Hab. Camaroons. The 2 resembles the $, but is larger. ROMALEOSOMA EDWARDSI, Hoev. Nymphalis (Aterica) edwardsii, Tijd. Nat. Ges. xii. p. 252, t. 4. f. 1 a, b (1845); Kirby, Cat. Diurn. Lep. p. 248. 12 (1871). Romaleosoma pratinas, Doubl. & Hew. Gen. D. L. t. 38. f. 3 (1850); Kirby, Cat. Diurn. Lep. p. 247. 5 (1871). These two described forms are certainly synonymic, as may be at once seen by a comparison of the figures. The mistake originated in the arrangement of the species of this genus by Doubleday and Hewitson in the Gen. D. L. p. 284. R. pratinas is included in the Sect., "body extremely robust, and marked on the upperside with large pale spots;" whilst R. edwardsi is placed in another Sect., " body less robust, not marked with pale spots," which is clearly erroneous, and seems to show that the figure of the last species was not consulted. ROMALEOSOMA LOSINGA, Hew. Ex. Butt. iii. Rom. t. i. f. 5 (1864). Romaleosoma ivardi, Druce, Cist. Ent. i. p. 286. n. 5 (1874). Mr. Hewitson described this species as having on underside of fore wings "three black spots (forming a triangle) within the cell," and posterior wings as having " a single black spot within the cell." Only one specimen which I have examined in the collection has a single spot only in cell of hind wing, and that specimen differs in only having two spots in cell of fore wing. Some specimens possess two spots in cell of hind wings, and some three; others have three in cells of fore and hind wings, and a transverse black fascia across end of cell. One specimen has a fourth spot on hind wing situated outside cell. In most specimens there is also a well-marked violet reflexion on upperside of hind wing near inner and hind margins, particularly the last. It will thus be seen that some of these forms agree with R. wardi, Druce; others, on the underside, with R, losinga, Hew. The cellular markings are evidently most inconstant, the violet reflexions above more pronounced in some species than others, and therefore I have been unable to separate the two species without adding varieties which would destroy the value of each. ROMALEOSOMA LAKUMA, Butl. Trans. Ent. Soc. 1870, p. 123; Lep. Ex. i. t. 21. f. 2(1871). This form is most inconstant in markings : in some male specimens tbe blue striae on anterior wings is absent; in some female specimens the discal blue streak extends at its base from abdominal margin to |
