The unfamiliarity of the material involves no change in the structure. Because of its finer grain and greater plasticity, the surface is more regular and the inside more homogeneous; and that is all. At the lower end of the sausage, which end is always rounded off, is the hatching-chamber, a circular cavity which could hold a fair-sized hazel-nut. The respiratory needs of the germ demand that the side-walls should be thin enough to allow the air to enter freely. Inside, I catch the gleam of a greenish, semifluid plaster, a simple exudation from the porous mass, as in the Copris’ ovoids and the Sacred Beetle’s pears. In this round hollow lies the egg, without adhering in any way to the surrounding walls. It is a white, elongated ellipsoid and is of remarkable bulk in proportion to the insect. In the case of the Stercoraceous Geotrupes, it measures seven to eight millimetres in length by four at its widest point. [49] The egg of the Mimic Geotrupes is a little smaller. This little hollow contrived in the substance of the sausage, at the lower end, does not agree at all with what I have read about the Geotrupes’ nest-building. Quoting an old German writer, Frisch, [50] an author whom the poverty of my library does not allow me to consult, Mulsant, [51] speaking of the Stercoraceous Geotrupes, says: ‘At the bottom of her perpendicular gallery, the mother builds, usually with earth, a sort of nest, or egg-shaped shell, open at one side. On the inner wall of this shell she glues a whitish egg, the size of a grain of wheat.’ What can this shell be, usually made of earth and open at one side so that the grub may reach the column of provisions overhead? I am at an utter loss to know. Shell, especially made of earth, there is none, nor any opening. I see and see again, as often as I wish, a round cell, closed everywhere and built at the lower end of the food-cylinder, but nothing else, nothing that even vaguely resembles the structure described. Which of the two is responsible for the imaginary construction? Can the German entomologist have sinned through superficial observation? Or did the Lyons entomologist misinterpret the older author? I lack the necessary documents to bring the mistake home to the right person. Is it not pathetic to see these masters, who are so punctilious about a joint of the palpi, so cantankerous about the first claim to some barbaric appellation, almost indifferent when they come to treat of habits and industry, which are the supreme expression of an insect’s life? Nomenclators’ entomology is making enormous strides: it overwhelms us, swamps us. The other, biologists’ entomology, the only interesting branch of the science, the only one really worthy of our attention, is neglected to such an extent that the commonest species has no history or calls for serious revision of the little that has been written about it. Vain lamentations: things will go on in the same old way for a long time to come.
