110 Dr. G. B, Longstaff on 
Mr. W. H. Edwards, in his Butterflies of North America, 
1897, quotes Mr. William Couper’s observation as to a 
habit of Colias philodice, Godt., in Anticosti :— 
When it alights on a flower, instead of being erect on 
its feet, it lies sideways, as if to receive the warmth 
of the sun. 
The original passage occurs in the Canadian Entomologist, 
vol. vi, p. 92, 1874; if therefore this be truly such a list as 
is under discussion, Mr. Couper deserves the credit of 
having first observed it, but at present I am doubtful on 
the point. 
In the summer of 1903, at Mortehoe, Dr. Dixey and I 
observed a like habit in Satyrus semele, L.; and later in 
that year (and in the following) I found that other British 
Satyrids, such as Pararge exgeria, L., and Megera, L.; 
Epinephele jurtina, L., and hyperanthus, L., had a similar 
habit, though less marked. The butterflies when confined 
in a box were seen to assume the list more often in sun- 
shine than in shade. * 
In India, in the late autumn of 1893 I noted the same 
habit in the Satyrines Hipparchia parisatis, Koll., and 
Aulocera swaha, Koll.+ 
On the voyage out to South Africa the usual call at 
Madeira gave us little more than a glimpse at its butter- 
flies. The local race of Satyrus semele, L., was common on 
the Caminho do Meio at an altitude of about 800 ft., and 
Dr. Dixey has this note :— 
Settled on the ground, low herbage, walls and tree- 
trunks. The fore-wings are depressed with a snap 
as in the English semele. Two were specially noted 
settling in sunshine (not strong) both turned head 
to sun and listedone to port and one to starboard. 
My note is: 
A specimen seen settled face to sun, list 30° to 
starboard. 
It was of course only to be expected that on the fifth 
day from leaving Southampton we should both use nautical 
phraseology. 
South Africa contributed little to increasing our know- 
ledge of the “list.” The genus Psewdonympha, somewhat 
suggestive of Hvelia, is characteristic of Cape Colony; at
