posterior _tarsi_ inserted beneath and within the termination of their plantæ; the claw-joint longer than the two preceding; _claws_ bifid, the inner tooth distant from the external. ABDOMEN ovate, subpubescent, the fifth segment densely fimbriated and the terminal segment with an emarginate appendage. In the MALES the antennæ are very similar, but the mandibles are more acutely bidentate, and with the exception of the form of the legs, the general aspect is like the female; the legs, although setose, are less conspicuously so, the intermediate tarsi in the first section of the genus being longer than the rest of the entire leg, and are fringed externally with very long hair, or it is restricted to the plantæ of that leg and then it is short and very rigid; the entire limb stretched out extends beyond the widest expansion of the superior wings. The ABDOMEN is also less retuse than in the female, at its basal segment. In the second division of this genus, of which _Anthophora furcata_ may be considered to be the type, the general habit is precisely the same, but the insects are not so pubescent, and there is a greater similarity between the sexes. The intermediate legs also, although long in the male, are not so extremely long as they are in the first section.

The name _ἄνθος_, _φὼρ φωρὸς_, _flower-rifler_, would be as suitable for any other genus of bees, and therefore may be classed with those names which have no explicit signification.
