some Kest-attitudes of Butterflies, Pit 
East London I observed several P. casstus, Godt., at rest, 
but did not see any list. 
Mycalesis safitza, Hew. Though I took many odd speci- 
mens of this dingy butterfly, I never found it really 
common, and have but two notes of its resting attitude:— 
Berea, near the hotel, Aug. 14th, seen to settle in the 
shade, wings upright. 
And, 
Congella, Aug. 18th. This species does not appear to 
orient : a slight list away from the sun, but sun 
not very bright at the time of observation. 
Dr. Dixey, however, in the case of this butterfly obtained 
more positive results :-— 
Durban (Botanic Garden), A/ycalesis safitza has a very 
strong list when settled in the open; it may be to 
right or left in the same individual. 
Durban (Botanic Garden), saw Mycalesis safitza 
settled on bare ground ; it had a strong list to the 
left. Saw it fly and settle in strong sunshine ; 
once with its back to the sun, with list to left; 
once with head to sun, right list; once at right 
angles to sun, throwing a broad shadow. 
It would therefore seem that Mycalesis safitza may be 
included among the Satyrs with a list, but this does not 
appear to help concealment by diminishing the shadow, as 
I suggested would be the case if the list were towards the 
sun.* 
Near Darjiling, in 1903, I observed a slight list in 
Mycalesis indistans, Moore. And in Japan, in 1904, the 
fine Satyrid, Blanaida goschkevitschii, Mén., had a striking 
list. 
General. 
That the term “Rest Attitude” is used in this paper 
very loosely I am well aware. A butterfly may be con- 
ceived as resting in several stages. First, it may settle to 
feed. Sphinx feeds on the wing; many a Papilio settles on 
a flower to feed, but flutters while sucking the honey, this,

P. dissimilis, L, Thus in Ceylon I found that the best 
way of distinguishing the last-named from the Danaids
