The coxa in their occa- sional processes exhibit very useful specific characters, as do the markings and form of the remaining joints of the leg and foot, which in several genera furnish generic pecu- liarities. The four anterior tarsi have each a moveable spine, or spur, at their apex within, which can be expanded to the angle at which the insect wishes to place the limb, and to which it forms a collateral support ; the posterior tibiae have two each of these spurs, excepting in the genus Apis, which has none to this leg. Attached to this spur on the anterior tibiae of all the bees, there is, with- in, a small velum, or sail, as it has been called; this is a small angular appendage affixed within the spur by its base. At the base of the palmse of the same legs, and opposite the play of this velum, there is a deep sinus, or curved incision, the strigilis, called thus or the curry-comb, from the pecten, or comb of short stiff hair which fringes its edge.
