Show 408 MR. A. G. BUTLER O N [May 4, distinctly white-bordered, the orange spots wholly absent from primaries, and the orange borders of the secondaries only represented by small ochreous lunules above the metallic spots, the latter silvery green with black centres instead of margins, extremely small towards the apex, but increasing in size towards the anal angle. Expanse of wings 1 inch 1 line. 2 . Of a more pinky lilac colour than the male ; the primaries with a considerably broader, but brown instead of black, border; a well-defined black discocellular stigma; secondaries with brown costal border; outer margin black preceded by five or six rounded blackish spots: wings below altogether paler than in the male; but the example is evidently not a fresh one, so that this character may be due to fading. Expanse of wings 1 inch I line. " Found in May, and common in June." The female is utterly unlike that sex of L. argus on both surfaces, being in coloration almost like a male insect. 13. SCOLITANTIDES CASHMIRENSIS (no. 11). Scolitantides cashmirensis, Moore, Proc. Zool. Soc. 1874, p. 272. " Very common here at the end of May and in June, but was rather local in Cashmir." 14. CHRYSOPHANUS STYGIANUS, sp. n. (no. 4). (Plate XXXIX. fig. 5.) $ . Smoky brown: primaries in certain lights shot with fiery copper ; spotted with black as in C. timeus (eleus ? Fabr.); two small orange spots beyond the interrupted black discal series; secondaries with a slender undulated deep-reddish-orange band on a black ground near the outer margin ; above it a series of four or five pale blue hastate spots, and above these again beyond the end of the cell two black dots; a black dash at the end of the cell; fringe greyish white : body blackish. Wings below very like C. timeus, but considerably paler, the submarginal black spots of primaries less distinctly white-bordered ; the apex and outer margin of primaries and the ground-colour of the secondaries very pale grey. Expanse of wings 1 inch 4 lines. 2 . Larger than the male, the primaries with the outer third of the cell and the subapical area bright orange, the black spots larger, otherwise similar : below slightly yellower in tint all over, so that the ground-tint of the secondaries has a pale brownish rather than greyish hue. Expanse of wings 1 inch 5 lines. " Common in April and May, abundant in June." This species is considerably larger than C. phlceas, and has the costal margin of the primaries longer.
