Differs from australiensis, Szep., in the colour of the

$ . Very similar to australiensis, differing in the shorter 

 ovipositor, which is distinctly shorter than the abdomen, in 

 the colour of the thorax and median segment, and in the 

 wholly black spine of the hind coxae. 



<$ . The whole second tergite is closely and finely longi- 

 tudinally striated ; the first tergite less regularly striated, 

 Avith punctures intermingled, but more distinctly striated 

 than in the female; the apical tergites very closely and 

 finely punctured. The apical half of the spine of the hind 

 coxae is yellow. The wings are paler than in the female, the 

 stigma almost entirely dull testaceous.
