I have no other information about the integral diet of this Wasp, whom I have neglected somewhat, preferring to study her cousin, the builder of rockwork domes.

As the two sexes differ in size, although to a lesser degree than in the case of Eumenes Amedei, I am inclined to think that those two well-filled cells belonged to females and that the males' cells must have a less sumptuous table.

Not having seen for myself, I am content to set down this mere suspicion.
What I have seen and often seen is the pebbly nest, with the larva inside and the provisions partly consumed.

To continue the rearing at home and follow my charge's progress from day to day was a business which I could not resist; besides, as far as I was able to see, it was easily managed.

I had had some practice in this foster-father's trade; my association with the Bembex, the Ammophila, the Sphex (three species of Digger-wasps .-- Translator's Note.) and many others had turned me into a passable insect-rearer.
