The Archippus Butterflt {Danais Archippus, Pabr.) The first insect of which we propose to treat is one of our commonest butterflies, known as the Archippus Butterfly (Dniwis Archippus.)

The few individuals which thus early appear, lay their eggs on the lender leaves of the young milkweed plants (Aadepias cornuti) and other species of Asclepias, and also on the bitter root (apoci/num AndroswmefoliumJ ; this takes place during the latter part of May or the beginning of June.
