finely longitudinally striated, with punctures between the 

 strife in the middle; curved basal area of second tergite 

 finely longitudinally striated, the apex almost smooth. 

 Ovipositor longer than the abdomen by about one-fifth. 

 Intermediate tarsi a little shorter than the tibiae ; hind 

 coxse with two spines, the basal one long and whitish, the 

 apical one very small and black. 



Hab. Port Darwin {Turner), December. 



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

 thorax, in the much more extensive striation of the first 

 tergite, in the striation of the basal area of the second 

 tergite which is wholly smooth in australiensis, and in the 

 colour of the stigma.

? . 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, 

 with 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 

 coxh3 is yellow. The wings are paler than in the female, the 

 stigma almost entirely dull testaceous.
