 Legs testaceous with coxae and trochanters black ; anterior femora 

 basally infuscate, hind ones nigrescent with apices pale ; hind tibiae 

 apically infuscate and, like their femora, not incrassate. Wings hyaline

 costa not extending to apex ; recurrent nervure and brachial cell entire. 

 Length, 3 mm. ^ unknown. 



This description is drawn from the authors cited, but l>risc]ik(^ was by 

 no means satisfied that his female was identical with the original one ;

Berlin (Grav.); Prussia (Brischke). I have seen no member of this 

 Tribe with basally glittering metanotum; the present species was intro- 

 duced as British in 1870 by the Rev. T. A. I\Iarshall, but there are no 

 records.
