1886.] LEPIDOPTERA FROM WESTERN INDIA. 369 



European collections ; it has been uamed /. coruscans for him, but 

 is not even nearly allied to that species, of which we possess the 

 types. Kollar's figure is not good, having been taken from a worn 

 and broken specimen, but the identity of the species is settled by 

 the "sky-blue gloss" of the basal half of the wings' ; as a matter 

 of fact the colour is ultramarine, but a little inaccuracy in colouring 

 is perhaps admissible in the description of a rubbed insect. Kollar 

 says, " We possess only a single example of this beautiful species, 

 and it has suflfered severely in transport, so that in fact only tJie 

 wings are preserved," and from the description we find that the hind 

 wings, at least, are " badly rubbed."

 20th September, 1885. 



" Rather rare at Murree, very common on the lower slopes of 

 Tliundiani, and as low as Tret and Bugnoter, probably not above 

 5000 feet."— J'. W. Y. 



55. SpiNDASis HYPARGYROS, sp. n. (Plate XXXV. fig. 3.) 



AUied to S. acamas and S. epargyros. Larger ; the male differing 

 from both in the whitish costal area of primaries and both sexes 

 differing in the darker bands on all the wings ; on the under surface 

 the wings are chalky white instead of cream-colour, all the markings 

 are darker and edged with black ; the subnaarginal band of the 

 secondaries is not angulated as in S. acamas and the secondaries 

 themselves are longer. Expanse of wings, S 36 millim., $ 35-38 

 millim. 



S ? , Campbellpore, 19th, 20th, 25th, 26th, and 28th July, 1885. 



This is the representative of S. acamas in N.W. India ; Col. 

 Swinhoe obtained it at Kurrachee and Chaman ; Major Yerbury 

 says that it is common". At the time when I identified it as iS. acamas 

 we did not possess that species, and I supposed that the differences 

 which existed in Klug's figures were due to inaccuracy of delineation. 

 The Zeller collection has, however, now put us in possession of 

 specimens of the true S. acamas and the aUied S. eparygros, and I am 

 able to see at a glance that here we have a series of those constant 

 local races which constitute the only existing species in the Order 

 Lepidoptera, but which, for that very reason, are always as thorns 



^ In /. coruscans the colour is shining metallic emerald-green. 



^ Another allied species occurs at Suakim ; it has recently been presented 

 to the Museum collection by Surgeon Mandest. It may be called S. bcUatrix. 

 This species is smaller than S. acamas, is bright tawny above, with a black 

 marginal stripe and white fringe ; the primaries show dusky indications of the 

 ordinary markings upon the costal half ; there is also a whitish spot in the 

 cell and a white subapical costal spot ; wings below chalky white, with pale 

 sandy-brownish markings edged with black and enclosing the usual silver 

 streaks and spots ; all the bands are a little wider than in 8. acamas, the central 

 band of primaries is abbreviated ; the subapical band of secondaries more 

 angular and the submarginal band interrupted. Expanse of wings 30 millim.
