have a head at each extremity: which deception is 
much increased by a spot resembling an eye at the 
base of the processes. These insects, perhaps, thus 
perplex or alarm their assailants.* 
Hesperia iarbas at first puzzled me, but it would appear 
to be the insect now known as Deudorix (Rapala) varbas, 
Fab., and the very close ally of D. melampus, Cram., one 
of the insects in which I first noticed the peculiar struc- 
ture of the anal lobe, about 86 years after Dr. Arnold’s 
observation ! 
I remember well seeing a Lyczenid at rest on a leaf at 
Solon, on the road to Simla, in October 1903, and was 
struck by its tails waving about, as I thought at the time 
blown by the wind. 
On March 12th, 1904, the pretty white, black and 
orange Talicaxnda nyseus, Guér., was positively swarming 
near Kandy. I repeatedly watched it settle with its head 
upwards and immediately turn about so that its head 
looked downwards.t 
At Mortehoe, June 5th, 1905, Mr. A. L. Onslow and I 
searched from sundown to dusk for Hmmelesia albulata, 
Schiff, in a field adjoiming my house; we failed in our 
search, but incidentally came across a number of Lycena 
icarus, Rott., asleep on the stems of grasses, etc. Out of 
fifteen specimens, twelve had the head down, three had 
the bead up.} 
The lobed and tailed Lycznids are not too easy to 
observe; they are active and commonly fly about the tops 
of shrubs or small trees; when at rest they are not 
conspicuous and when disturbed dart swiftly off. 
Dr. Dixey noted :— 
Aug. 20. Durban (Botanical Garden). Saw an 
“amphisbaenoid” Lycena settled twice; the first 
time horizontally, the second time head downwards. 
On both occasions the “ false head“ looked much 
more like a head than the real one did. There was 
a constant slight movement of the hind-wings; and 
a waving of the false antenne.

{ When this butterfly first settles on flowers in full sunshine it 
expands its wings very fully, the primaries being drawn somewhat 
away from the secondaries.
