^. — Size, colour, and general appearance agreeing with 

 E. argyreus, with the same silvery hair covering the pleura, 

 thougli not quite so densely, and also on the face, though 

 failing below, so as to leave the lower part of the very minutely 

 and densely punctured clypeus visible. The black spurs also 

 are the same, and the hyaline wings. Tlie following differ- 

 ences are important : — Man libles with more red; margin of 

 labrum red ; face less narrowed below ; third antennal joint 

 longer ; flagellum ferruginous beneath except at base ; meso- 

 thorax less hairy, leaving a large anchor-shaped black area 

 very densely punctured, its stem reaching the anterior margin ; 

 tegulte piceous basally, red in the middle, and with hyaline 

 margin ; area of mttathorax almost entirely covered with 

 hair; marginal cell less slender; second t.-c. complete; 

 knees, femora, and tibiie red ; transverse band on first abdo- 

 minal segment large and clean-cut ; band on second segment 

 Avith a large hook-like process on each side ; erect fringe on 

 fourth and fifth ventral segments white.

 I'csemble T.lunatus and heUanthi, and weie confused with
