The calcaneum also has a facet that attaches to both the fibula bone of the leg and another tarsal, or ankle bone.
The tarsal gland appears to operate by a different mechanism than the other external scent glands.
Their legs usually end in two tarsal segments with a bladder-like structure known as an arolium at the pretarsus.
When there is a more severe upper lid retraction or exposure keratitis, marginal myotomy of levator palpebrae associated with lateral tarsal canthoplasty is recommended.
Like many other insect orders, beetles bear claws, usually one pair, on the end of the last tarsal segment of each leg.
The tarsal glands are found on the upper inside of the hock (middle joint) on each hind leg.
After the pelvis come the femur (thigh), patella, stifle joint, tibia, fibula, tarsal (hock) bone and joint, large metatarsal (cannon) and small metatarsal (splint) bones.
The anterior legs are sometimes without any dark scales, sometimes with the tips of the joints black and the whole of the last two tarsal joints brownish.
