Papilio daiinus. 



One has to use great care in removing these grand insects from 

 the net, as the slender tails of the lower wings are easily broken. 



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.
