BUTTERFLIES, MOTHS AND CICADAS 205 



Another of these protectively-coloured moths was 

 Gnophus variegata, a much smaller and lighter-coloured 

 species mottled with a yellowish or pinkish tinge which 

 harmonized fairly well with the hue of the mountain 

 limestone. Its colours did not blend quite so accu- 

 rately as was seen in some of the other species, unless 

 it happened to alight on a specially suitable patch of 

 stone. And we should remember that this limestone 

 is marked with many streaks and patches, tinted with 

 numerous shades of colour, clothed with different kinds 

 of fungi, all of which so vary its surface as to fit it for the 

 concealment of a number of distinct and varied species. 



Anonychia rostrifera was another very common 

 species. It was a pretty little grey moth with a brown 

 angulated pattern on the upper surface of the wings. 

 It took refuge on the dark shales and I seldom saw it 

 on the limestone. It does not harmonize so well as 

 some of the previous species, and it seemed to prefer 

 a somewhat lower altitude of 6000 to 7000 feet. 

 There was also another little moth that sought the 

 limestone, the name of which I did not determine. It 

 was of a uniform grey colour and harmonized ex- 

 ceptionally well with the weathered areas of the stone. 

 This species seemed to rely even more than the others 

 on its close resemblance to its environment, for I found 

 that it was less liable to take alarm and less inclined to 

 leave its shelter than any of the previous species. 



Abraxas sylvata was still another of the Hazara 

 moths that possessed the habit of alighting on the 

 crags of limestone. It is a white insect, with its fragile 

 wings studded over with patches and spots of grey. 

 This species harmonized fairly well with the stones, 

 though any one seeing the insect in a museum would
