summary of the habits of these two forms so far as I have 
observed them in Natal. It will be seen at a glance that they 
are widely different. 
E. wahlbergi. 
To be found from middle of | 
December and during January | 
and part of February.* 
Imago emerges from pupa | 
p.m., never in the morning. 
between 9.30 and 11.30 a.m. 
Always rests upon upper 
surface of leaves or the ground 
with wings folded except when 
drying after emergence, when 
they are continually opened 
and shut like those of a Sat- 
urnid moth. 
Flight slow and hovering, 
and when disturbed the insect 
usually returns after a time 
to the same spot, often to the 
same leaf. 
Very much commoner than 
£. mima: at least ten of wahl- 
bergi may be seen to one of 
mimd. 
E. mima. 
To be found about first 
week in January and during 
February. 
Emerges between 2 and 4 
Always rests upon the under- 
side of the leaf with wings 
shut and hanging down, except 
when drying, which usually 
occurs upon the sand or very 
low herbage. 
Flight very much quicker 
than /. wahlbergi, and if dis- 
turbed or missed the butterfly 
flies high and does not return 
to the same place. 
One of the rare species here. 
I should consider ten to twelve 
aprobableestimate of the num- 
ber which might be seen in an 
average season. 
I think there is sufficient difference in the habits set forth 
above to indicate that we are dealing with distinct species, but 
a few additional remarks may not be out of place. I have 
often seen and captured specimens of wah/berg? no larger than 
E. mima, but I have never seen, or heard of any of the latter 
that in any way approach the size of a very large proportion 
of the former. JWuhlberyi may also be seen in gardens and 
sometimes even in the public roads, while mima is very rarely 
found except in shady glades in the bush. 
* Mr. Leigh writes on May 26, 1906:—‘‘I have seen two or three 
Euralia wahlbergi this month: last year I saw none after February and 
early March. The specimens now seen are very much larger than the 
earlier brood, but not socommon.” [E. B. P.]
