Show 386 MR. A. G. BUTLER ON NEW LEPIDOPTERA. [Apr. 2, large oblique oval white spot black ; secondaries with the apex and a more or less confluent marginal series of dots at the terminations of the nervures black ; body yellow, banded with black. Expanse 1 inch 9 lines. Dar-es-Salem, Zanzibar (J. fy F. Moir). A delicate little species, resembling the New-world genus Stenele. 14. ALETIS VARIABILIS, n. sp. 2 • Ochreous; primaries with the apical two fifths blackish, enclosing a large transparent white patch beyond the cell, and two smaller pyriform spots on the median interspaces ; secondaries with a regular blackish border enclosing nine transparent white spots, most of which touch the outer margin ; body greyish, spotted with white. Expanse 2 inches 3 lines. Ambriz (Monteiro). 2 . Var. a. Primaries with the pyriform spots elongated into ellipses which distort the blackish border, also a third bifid spot below them completely interrupting the border near the external angle ; secondaries with the white marginal spots confluent and breaking through the border at apex. Ambriz (Monteiro). d • Var. b. Primaries with all the white spots confluent, forming a large irregular hyaline patch which almost covers the disk; secondaries with the inner edge of the marginal border only traceable near the anal angle, the white spots expanded into a broad hyaline belt, which widens gradually to the costa. Angola, Bembe Mines (Monteiro). A. variabilis is much like Stenele lutescens. The other species of Aletis in the Museum were all placed by Mr. Walker under A. helcita, to which they are allied. They are as follows :-* 1. A. libyssa, Hopffer, from Natal and the Zulu country. 2. A. fascelis, Linnaeus, from the Congo. 3. A. helcita, Clerck, from Western Africa (exact locality unknown). 4. A. druryi = A. helcita, Drury, 111. iii. pl. 29. f. 4. Sierra Leone. 5. A. macularia, Fabricius, from Ashanti. Of these forms A. libyssa is the most decidedly distinct, the others are mere local modifications of one type differing from one another in the size and number of the white spots of primaries and the width of the black border of secondaries. Cramer's A. helcita is the same as that figured by Drury. DEILEMERA, Hiibner. 15. DEILEMERA SIGNATA, n. sp. Allied to D. artemis, Boisd., and D. pellex, Linn. (Nyctemera separata, Wlk.), but smaller than either, with the broad white postmedian patch of primaries reduced to a quarter the size, and with the dark border of secondaries of double the width. Expanse 1 inch 7 lines. Damley Island (Dr. W. Y. Turner). |
