But, without saying anything positive on this point, I will draw
attention to certain deep fissures which seem to threaten the soft
bread with desiccation, inadequately protected as it is by the cracked
jar. Have no fear that these spontaneous breaches will do any harm: the
larva will soon put them right. In the distribution of gifts, it was
not for nothing that the trowel and putty were awarded to the Sacred
Beetle’s grub.
We will now give a brief description of the larva, without stopping to
enumerate the articulations of the palpi and antennæ, which are
wearisome details of no immediate interest. It is a fat grub and has a
fine, white skin, with pale slate-coloured reflections proceeding from
the digestive organs, which are visible when you hold the creature to
the light. Bent into a broken arch or hook, it is not unlike the grub
of the Cockchafer, but has a much more ungainly figure, for, on its
back, at the sudden bend of the hook, the third, fourth and fifth
segments of the abdomen swell into an enormous hump, a tumour, a bag so
prominent that the skin seems on the point of bursting under the
pressure of the contents. This is the animal’s most striking feature:
the fact that it carries a knapsack.
The head is small, in proportion to the grub’s size, is slightly
convex, bright-red and studded with a few pale bristles. The legs are
fairly long and sturdy, ending in a pointed tarsus. The grub does not
use them as a means of progression. When taken from its shell and
placed upon the table, it struggles in clumsy contortions without
succeeding in shifting its position; and the helpless creature betrays
its anxiety by repeated discharges of its mortar.
Let us also mention the terminal trowel, that last segment lopped into
a slanting disk and rimmed with a fleshy pad. In the centre of this
inclined plane is the open stercoraceous slit, which thus, by a very
unusual inversion, occupies the upper surface. A huge hump and a
trowel: that gives you the insect in two words.
In his Histoire naturelle des coléoptères de France, Mulsant describes
the larva of the Sacred Beetle. He tells us with meticulous detail the
number and shape of the joints of the palpi and antennæ; he sees the
hypopygium [25] and its pointed bristles; he sees a multitude of things
in the domain of the microscope; and he does not see the monstrous
knapsack that takes up almost half the insect, nor does he see the
strange configuration of the last segment. There is not a doubt in my
mind that the writer of this minute description has made a mistake: the
larva of which he speaks is nothing like that of the Sacred Beetle.
