duces successive broods of Marcellus the same season, and occasionally Telamonides, 
(individual taken by Mr. Mead in September, 1870) and the last brood produces 
Walshii and Telamonides in the Spring; and whenever any of the chrysalids of 
either brood of Marcellus pass the winter they produce the other two varieties, and 
probably sometimes their own type (individual taken April, 1867.) The chrysa- 
lids of Walshii that pass the winter of 1871 — 2 will probably produce Walshii 
or Telamonides. 
Thus there are Marcellus produced by three different types of parent, and Tel- 
amonides by three and probably Walshii by the same number. I have carefully 
compared individuals of each variety so sprung from several parents and can dis- 
cover no tangible points of difference. Except in what I should call non-essential 
variations and which each variety is subject to, such as width of the bands, &c., 
each is true to its own type no matter what its parentage. 
The duration of the several states of egg, larva and chrysalis also differs 
greatly, especially between Walshii and the other two varieties.

The female of Ajax may frequently be seen coursing through the pawpaw trees 
which hereabouts cover the lower hill-sides, or hovering about the young plants 
that spring up in the cultivated fields, searching for leaves on which to deposit 
her eggs. After touching or running over and rejecting several, she finds one 
suitable to her purpose. Thereupon, balancing by the rapid fluttering of her wings, 
she stands for an instant with legs stretched at full length, perpendicular to the 
body, and curving down the abdomen till it touches the surface, deposits a single 
egg; then flies away, presently to alight on a second leaf with like intent. Some- 
times the egg is upon the stem and occasionally on the under side of the leaf, but 
almost always it is on the upper side, and but one egg will usually be found on 
the same leaf. The process of laying continues for several successive days. At 
certain seasons it is almost impossible to find a young plant that is free from these 
eggs and it is easy to collect scores of them. 
On dissecting the abdomen of a newly emerged female the eggs are found to 
be fully formed though not full-sized. I conclude that they mature with great 
rapidity because fertile eggs are laid by apparently fresh and uninjured females. 
With the Yanessans and Argynnides, (probably with the Nymphalidse generally,) 
this is far from being the case, the eggs maturing in the ovaries for a long period 
before they are ready for impregnation.
