ANTHOPHORA. 237 



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 tibiae and 

 plants 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 

 plantse; 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 antennse 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 con- 

 spicuously 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 plantse 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 Antho- 

 phora 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 be- 

 tween the sexes. The intermediate legs also, although 

 long in the male, are not so extremely long as they are 

 in the first section.
