Note 1 — Chapter XVIII · THE LOCUSTS: THEIR EGGS

We will now describe specifically the layings which we find in the cages. That of Pachytylus cinerescens is a cylinder six centimetres long and eight millimetres wide.1 The upper end, when it emerges above the ground, swells into a nipple. All the rest is of uniform thickness. The yellow-grey eggs are fusiform. Immersed in the froth and arranged slantwise, they occupy only about a sixth part of the total length. The rest of the structure is a fine, white, very powdery foam, soiled on the outside by grains of earth. The eggs are not many in number, about thirty; but the mother lays several batches.
