 from its surroundings." (From a letter to the 

 author.) 



The late Mr. C. G. Barrett, in an admirable account of 

 the habits of the same butterfly, wrote as follows : — 



"... it even seems to lie down sideways, or at 

 any rate to so greatly slope its closed wings as to 

 appear prostrate." *

The case of our commonest butterfly is especially in- 

 teresting, since its habits are irregular and partake of 

 those of G, jpamphihis and S. scniele. 



Mortehoe, 20 July, 1906. H. janira. Four specimens 

 oriented ; of these, 3 had the wings open, 1 closed. 

 Eleven specimens were settled across the sun, with 

 wings closed ; certainly one of the latter listed from 

 the sun. 

 July 30. Some noticed to orient ; others sitting across 

 the sun. 



Mortehoe, 11 August, 1907. 1 ^and 2 $ oriented; wings 

 three-quarters open. Others seen across the sun and 

 one of these listed. The wind was however this day 

 too strong for trustworthy observations. The butter- 

 flies mostly sat head to the wind. 



Mortehoe, 15 August, 1907. Several specimens noted 

 settled on grass, on or near the ground. Of these 

 8 $ oriented, 1 with the wings quite open, the 

 other 2 three-quarters open. A % oriented with 

 the wings open ; another ^ settled on a leaf oriented 

 with the wings three-quarters open. Another $ sat 

 across the sun, had its wings up, and listed away 

 from the sun. The eye-spot on the fore-wing some- 

 times obscured, sometimes in part visible. 



Mortehoe, 16 August, 1907. A $ seen to settle three 

 times across the sun, with its wings closed, leaning 

 away from the sun. Yet another ^ was seen to settle 

 three times ; twice across the sun, with wings closed, 

 but on the third occasion with its wings open and 

 fairly oriented.
