at the base ; the rim projecting over at the apex ; the sides of scutellum 

 rugose. Metathorax (especially the sides of the metanotum) densely 

 covered with griseous white hair ; the keels on the metanotum bulging 

 outwardly, red. Abdominal hair-fringe dense, griseous-white ; ventral 

 surface of abdomen piceous-red. Radius continued near to the apex ; 

 apex of wings longly fringed. 



The <J has the antenna3 about two-thirds longer than the body, the 

 third joint shorter than the fourth. 



Length 2| 3 mm. 



Not common. Norwich (Bridgman), Caterham 

 (Champion).

Black ; the flagellum and legs (except the basal three-fourths of 

 coxa3) red ; the tegula3 piceous ; wings yellowish-hyaline, the nervures 

 testaceous. Antenna filiform, longer than the body, the sixth and fol- 

 lowing joints not thicker than the fifth, elongated, much longer than 

 broad ; the third joint shorter than the fourth. Scutellum rugosely 

 punctured ; the cup orbicular, narrowed at the base ; the rim piceous ; 

 the fovea at the apex large, wider than long. Hair on sides of meta- 

 notum moderately long, griseous. Abdomen not much longer than the 

 thorax ; its hair-fringe thick, griseous. Wings large ; first abscissa of 

 radius about three-fourths of the length of the second, and both are 

 clearly curved ; the third abscissa about the length of basal two 

 united, slightly curved; cubitus reaching to the apex of the wings; 

 apical fringe moderate. 



The <$ has the antennae one and three-fourths longer than the body ; 

 the third joint is shorter than the fourth. 



Length 4 mm. 



Closely allied to E. mandibularis, but that has the 

 antennae not much longer than the body, and with the 

 apical eight joints thicker than the preceding and 

 scarcely twice longer than wide ; the wings are clear 

 hyaline, the nervures paler ; the cubitus does not reach 

 to the apex of the wing ; the tegula3 are entirely red.
