408 MR. A. G. BUTLER ON [May 4, 



distinctly white-bordered, the orange spots wholly absent from the 

 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. 



5 . Of a more pinky lilac colour than the male ; the primaries 

 ■nith 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 1 line. 



" Found in May, and common in June." 



The female is utterly unlike that sex of Z. 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 STYGiANTJS, sp. n. (no. 4). (Plate XXXIX. 

 fig. 5.) 



S . Smolcy brown : primaries in certain lights shot with fiery 

 copper ; spotted with black as in C. timeits (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. 



5 . 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 0. pMccas, and has the 

 costal margin of the primaries longer. 



Papilionid^.
