308 BRITISH BEES. 



basal joint very robust, and its terminal joint twice as 

 long and linear. THORAX globose, very hirsute, whence 

 its divisions are inconspicuous ; scuiellum lunate ; meta- 

 thorax truncated; wings with three submarginal cells sub- 

 equal^ or the third the longest, and a fourth slightly com- 

 menced, the second receiving the first recurrent nervure 

 near its centre, and the third receiving the second re- 

 current nervure close to its extremity; legs robust, 

 pilose, the four anterior plantse with a dense, short, se- 

 tose brush beneath ; the posterior tibia triangular, very 

 smooth, and irregularly concave on their external sur- 

 face, fringed with long pile along its two external edges, 

 and its extremity tipped with a short pecten of stiff setse ; 

 the plantts elongate and broad, nearly equal, externally 

 shagreened and spiuulose, with a longish auriculated 

 process at the external angle of the superior edge, a 

 dense brush of short, stiff hair beneath, and a short 

 pecten of stiff setse edging its subemarginate extremity ; 

 the claw-joint the longest of the four short subsequent 

 joints, and the claws bifid. ABDOMEN ovate or globose, 

 deflected towards its extremity, its base retuse, the last 

 segment triangular, and terminating obtusely. 



The MALE differs in always being more intensely co- 

 loured ; in having the antenna distinctly longer, less dis- 

 tinctly geniculated, the scape shorter, the third joint of 

 the flagellum almost as short as its basal joint, and the 

 fourth as long as the terminal one, which latter two 

 are the longest of all, and the joints from the fourth to 

 the eleventh severally more or less slightly curved.
