wing similar to fore wing but with black tails, black tornal and anal marginal lobes, and gleaming blue antemarginal lines along the tornus. Ventral surface: fore wing ground colour as on dorsum but with median pattern of gleaming blue intercellular lines from cell R2 to M3, crescent-like markings in cells CuAl and CuA2, and the entire submargin with a row of dull greenish spots. Hind wing similar to fore wing but with gleaming submedian pattern of intercellular lines from cell Sc+Rl to cell CuAl, a vertical postmedian line of crescent-shaped intercellular markings, a submarginal row of dull antemarginal intercellular lines from cell Ml to tornus, a vivid marginal blue line, and black tornal and inner marginal lobes. Body gleaming bluish green dorsally, brown ventrally. Genitalia (Fig. 9): typical of genus, ductus bursae with long and tubular anterior element and heavily sclerotized, pocket-like, posterior element some one-fourth the length of the anterior. Etymology - Belus is the son of Danaus in Egyptian mythology; it is used here to signify the sister species relationship with the type species of the genus. Note-The holotype and allotype were figured d' Abrera (1995, I.e.) and have been misidentified as "Thecla danaus" male and female, respectively. Margaritheclus dabrerus sp. n. (Figs 10-11) Thecla ? sp. -d'Abrera 1995: 1131, fig. "T. ? sp. S R" (dorsal surface) and fig. "T. ? sp. S V" (ventral surface). Type - Holotype female, deposited in the Natural History Museum, London (BMNH), labelled as "15." (black ink, handwritten); 67.20 / Ex Coll. / Ed. Brabant / 1920" (printed); "J. J. Joicey Coll. / B.M. 1929-^135" (printed); "Bálint 7, / 28A 106" (handwritten "Rothschild / Bequest B.M. 1939-1." (printed)". The specimen is in moderately good condition: apex of left fore wing missing, wings slightly worn, abdomen missing. Diagnosis - Similar to M. danaus in size, wingshape, and ventral pattern but female hind wing vein CuAl just slightly convex at its distal terminus (tailed in M. danaus) and with the dorsal surface of the wings tinted blue (green in M. danaus); there is no wide black submarginal border (this border is wide and black on the dorsal surface of M. danaus), the submarginal area of the ventral surface shows a continous line of gleaming blue intercellular stripes from costa to vein 1A+2A. Description - Female (Figs 10-11). Size: fore wing length 22 mm (= holotype). Wing shape: fore wing costa convex, apex pointed, distal margin slightly convex, tornus rounded, anal margin straight; hind wing costa convex, apex rounded, distal margin straight, lobate at tomus, inner margin convex also with
