BUTLER ON BUTTERFLIES FROM [June 18, cell encloses a shining green spot; the silver markings on all the wdngs are arranged nearly as in A. lathonia, but are much more uniform in size; the characteristic oblong spot beyond the cell of secondaries is larger than that in A. euphrosyne, but smaller than that in A. lathonia. Expanse of wings 46 millim. Kasungu Mountain, Nyika, west of Lake Nyasa, Sept. 2nd, 1893. " Silver-speckled Fritillary " (R. ft). Mr. Crawshay has the following note on this butterfly:-" No. 1 I took at the very summit of Kasungu Mountain, on open down-land, covered with short, crisp, curly grass, only about ankle-high, I don't think I saw more than three, two of which I took (one I have by me). It is an exceedingly restless insect, of erratic flight, and, when on the wing, is a bad colour to follow with the eye. I did not find it anywhere but on the very top of the mountain; 100 feet or so lower down I did not see one." 6. ACREEA EXCELSIOR. Acrcea excelsior, E. M . Sharpe, P. Z. S. 1891, p. 192, pi. xvii. fig. 3. cf, Kasungu Mountain, Nvika, west of Lake Nyasa, Sept. 2nd, 1893. " Small Eed-barred Fritillary " (R. ft). Of this insect Mr. Crawshay says :-" A little Fritillary from nearly the top of Kasungu may prove good. I saw only one, which I took in the same place as the great Blue No. 2." Although the Acrceince somewhat remind one of Fritillaries, they belong to a different subfamily. 7. POLYOMMATUS BEETICUS. Papilio bceticus, Linnaeus, Syst. Nat. i. 2, p. 789 (1767). 2, Kantorongondo Mountain, Nyika, west of Lake Nyasa, Sept. 5th, 1893. " Blue " (R. ft). It is almost impossible to get a collection from any part of the Old World which does not contain an example of this species and Pyrameis cardui. 8. LYCEENESTHES (sp. near L. liodes). 2, Kasungu Mountain, Nyika, west of Lake Nyasa, Sept- 2nd, 1893. " Dull-marked Blue " (R. ft). This species has almost exactly the same pattern as L. liodes, but the secondaries are elongated and with an abrupt elbow close to anal angle; although probably new, the single specimen is unfortunately a good deal injured. 9. ZIZERA UNIGEMMATA, sp. n. (Plate XXXV. figs. 4, 5.) cf. Allied to Z. lysimon -. above smoky grey-brown, with faint lilacine gloss ; a slender blackish marginal line : secondaries with a submarginal black spot with paler diffused edging; slightly orange at the back near extremity of first median interspace; fringes smoky greyish, darker on the primaries than the secondaries', |
