?. Length 7 mm. Black ; palpi, knees, anterior tibiae, and tarsi obscurely 

 fuscous. Head and thorax coarsely rugose ; petiole longitudinally rugose, smoother at 

 the base ; mesopleura in front smooth, shining, impunctate, behind coarsely reticulated ; 

 breast covered with large shallow punctures. Coxae finely rugose, smooth at base. 

 Posterior femora not much longer than thorax ; tibiae and tarsi armed with short thick 

 bristles ; tarsi not much longer than tibiae ; claws apparently simple. The head, thorax, 

 and legs at the base are closely covered with a white velvety pubescence, which is 

 longest at the sides. Abdomen smooth, shining, compressed, shortly pilose at the 

 sides. Antennae longer than the body ; the apex of scape brownish. Wings hyaline ; 

 cubital and discoidal nervures obsolete from the discoidal cellules, the upper of which 

 is not at all so broad in proportion to the lower as it is in E. laevigata ; the transverse 

 humeral nervure is interstitial. The mandibles have two short obtuse teeth besides 

 the large apical one. 



This species is apparently most nearly allied to E. tasmanica, Westw., but the 

 present species has not the face longitudinally striated. (Cameron.)
