The preparatory stages of this species do not seem to have been described. Mr. Hy. Edwards in his catalogue gives eleven references, but in none is the egg mentioned, or any but a single larval stage, and in only one the pupa. It will, therefore, not be amiss to briefly describe the several stages here. I would like first to call attention to the remarkable fertility of the insect in question, at least in Southern Florida where I met with it.
