MOTHS AND BUTTERFLIES. 
This species may be easily distinguished from Apatura flora and 
Apatura clyton by the eye-spot on the upper side of the upper wing 
near the outer margin. Apatura celtis has this spot, but the insect is 
smaller and more sombre in color than the present species. 
The genus Limenitis is distinguished by having straight and slen¬ 
der antennae, with a gradual thickening toward the end instead of a 
distinct club. The lower wings are scalloped. This genus comprises

of the humps and horns with which their bodies are adorned. They 
are of various colors, being generally mottled and spotted in a strik¬ 
ing manner. 
Limenitis Ursula. Male. 
A very beautiful species of this genus, and one with which almost 
every young collector is familiar, is Limenitis Ursula. The butterfly 
is plentiful in June, and may most often be seen about damp places 
on the roads, where it is usually so intent on sipping the dirty water 
that it may be easily taken. After it is once alarmed it is a very 
difficult insect to capture, as it flies rapidly and is very wary. Some¬ 
times a second brood makes its appearance early in September. In 
Massachusetts it is not often common at that time of year, but in 
Ohio and others of the western states the second brood is sometimes 
as numerous as the first, and under the sweet apple and pear trees I
