Papilio daunus. 
One lias to use great care in removing these grand insects from

An insect which looks a good deal like Papilio daunus , except 
that it is smaller and the bands of black on the margins of the wings 
are broader, is Papilio pilumnus. 
The points or tails on the lower wings are even more marked than 
in Papilio daunus and the insect is of somewhat slighter build. It 
is a very beautiful butterfly, but is more a Mexican insect than 
properly belonging to our fauna. It is occasionally taken in Arizona 
and Texas.
