rse after they are hatched, I
went during the winter to Carpentras and inspected the banks inhabited
by the Anthophorae. There, as in my boxes, I found the larvae piled
into heaps, all mixed up with the skins of the eggs.

CHAPTER III
THE PRIMARY LARVA OF THE SITARES

Nothing new happens before the end of the following April. I shall
profit by this long period of repose to tell you more about the young
larva, of which I will begin by giving a description. Its length is a
twenty-fifth of an inch, or a little less. It is hard as leather, a
glossy greenish black, convex above and flat below, long and slender,
with a diameter increasing gradually from the head to the hinder
extremity of the metathorax, after which it rapidly diminishes. Its
head is a trifle longer than it is wide and is slightly dilated at the
base; it is pale-red near the mouth and darker about the ocelli.

The labrum forms a segment of a circle; it is reddish, edged with a
small number of very short, stiff hairs. The mandibles are powerful,
red-brown, curved and sharp; when at rest they meet without crossing.
The maxillary palpi are rather long, consisting of two cylindrical
sections of equal length, the outer ending in a very short bristle.
The jaws and the lower lip are not sufficiently visible to lend
themselves to accurate description.

The antennae consist of two cylindrical segments, equal in length, not
very definitely divided; these segments are nearly as long as those of
the palpi; the outer is surmounted by a cirrus whose length is as much
as thrice that of the head and tapers off until it becomes invisible
under a powerful pocket-lens. Behind the base of either antennae are
two ocelli, unequal in size and almost touching.

The thoracic segments are of equal length and increase gradually in
width from front to back. The prothorax is wider than the head, but is
narrower in front than at the base and is slightly rounded at the
sides. The legs are of medium length and fairly robust, ending in a
long, powerful, sharp and very mobile claw. On the haunch and thigh of
each leg is a long cirrus, like that of the antennae, almost as long
as the whole limb and standing at right angles to the plane of
locomotion when the creature moves. There are a few stiff bristles on
the legs.

The abdomen has nine segments, of practically equal length, but
shorter than those of the thorax and diminishing very rapidly in width
toward the last. Fixed belo
