In my last paper were concluded all the observations I have at present to publish, regarding the rearing of butterflies from the egg. Before passing on to relate some experiments of a similar character with moths, I propose to give what further notes I have made in this family from captured larvæ, partially or full grown.

To your readers who study Hymenoptera, it may be interesting to learn something of the economy of a little Bee which was found at Quebec by Mr. N. H. Cowdry, on the 11th April, 1865. The wood cut represents tops of raspberry canes, the pith of which was bored into, and emptied out by the parent Bee. 1. Orifice which was closed with some kind of vegetable substance. 2. Egg* of Bee attached to Pollen. 3. Pollen, all of which, under the microscope, appeared to have the same form and color (yellow), evidently mixed with honey.
