†† _With three submarginal cells to the wings._ Genus 11. ANTHOPHORA, _Latreille_. (Plate VI. fig. 3, and Plate VII. fig. 1.) APIS ** _d_, 2 _a_, Kirby.
_Gen. Char._: HEAD transverse, nearly as wide as the thorax; _vertex_ depressed; _ocelli_ placed in a curved line upon its posterior margin; _antennæ_ short, subclavate, basal joint of flagellum globose, its second joint longer than the scape, very slender, the rest of the joints subequal; _face_ flattish; _clypeus_ protuberant; _labrum_ quadrate, convex; _mandibles_ distinctly bidentate and obtuse; _cibarial apparatus_ very long; _tongue_ very long, transversely striated, and with a small knob at the extremity; _paraglossæ_ about one-third the length of the tongue, acuminate; _labial palpi_ slender, more than half the length of the tongue, membranous, the basal joint as long again as the remainder, the second joint very slender and very acute; the two terminal joints very short and subclavate, inserted before the extremity of the second joint; _labium_ short, one-fourth the length of the tongue, its inosculation concave; _maxillæ_ hastate, not so long as the tongue; _maxillary palpi_ one-third the length of the maxillæ, six-jointed, the basal joint very robust, the rest filiform, the second the longest, and all the rest decreasing in length and substance. THORAX oval, densely pubescent, which conceals its divisions; _metathorax_ truncated; _wings_ with three submarginal cells, closed, the second receives the first recurrent nervure in its centre, and the third, which bulges externally, receives the second at its extremity; _legs_ setose, the exterior of the posterior _tibiæ_ and _plantæ_ moderately so, and the interior of the latter also densely setose; the second joint of the 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.
