Belongs to the small group with red legs. E. 

 erythropoda differs from it in being larger, in the thorax 

 being largely marked with red ; and in the petiole not 

 being distinctly narrowed at the base and in being coarsely 

 rugose. The form of the median segment is the same — 

 rounded at the base, oblique at the apex — but it differs 

 in the middle of the apex, having a deep triangular 

 depression. 



Antennae black, distinctly thickened towards the 

 apex ; the scape shining, covered with black, short hair ; 

 the flagellum bare, not shining. Front and vertex strongly 

 punctured, shining, sparsely covered with longish, fuscous 

 hair; the antennal tubercles yellow, large, rounded at the 

 base, gradually narrowed from the end of the rounded 

 part to the apex. Clypeus with the middle of the apex 

 curved, the sides oblique ; thickly covered with silvery 

 pubescence ; at its base are two large, oblique, yellow 

 marks narrowed on the inner side ; the apex of the labrum 

 rufous, as is also the apical half of the mandibles. Thorax 

 coarsely punctured; closely covered with white pubes- 

 cence; that on the median segment being the longer. On 

 the centre of the pronotum is a complete yellow line, a 

 little curved round at the edges ; on the sides joined to the 

 central line is a shorter, yellow mark, narrow at the base, 

 widened gradually to near the apex, which again is slightly 

 narrowed, broadly obliquely on the hinder side, more 

 rounded on the outer and at the apex; yellow also is aline 

 on the keel at the side of the apex of the scutellum ; the 

 post-scutellum, a thin line at its side, a mark in front of 

 this, a somewhat oval mark on either side near the apex 

 of the median segment, and a bullet-shaped mark on the 

 mesopleurae, near the tubercles. In the centre of the 

 mesopleurae is a furrow, obscurely crenulated at the base, 

 widened and smooth at the apex. The base of the meta- 

 pleurae smooth and impuiictate, except the space over the
