This species may be distinguished by the smooth opaque 

 meson otum. The second cubital cell varies much in size, being 

 sometimes almost obsolete, as on one side in the type of* Tarcmga 

 chtbia. The recurrent nervures are trstially interstitial with the 

 transverse cubital nervures, but where the second cubital cell is 

 reduced the first recurrent is received before the apex of the 

 first cubita.l cell. I can find absolutely no difference between 

 Australian and New Zealand specimens, and have no doubt that 

 the species has been imported into the latter cotintry dtiring the 

 last century.

5 . Nigra ; segmentis^dorsalibus 1-3 apice angtiste albo-pilosis ; 

 alis fusco-hyalinis, venis nigris ; mesonoto punctato ; s'egmento 

 ventrali secundo in disco sparse punctato. 



Long., $ 14 mm., S 12 mm. 



$ . Clypeus rounded at the apex, slightly but broadly pro- 

 duced in the middle of the apical margin, closely and very finely 

 punctured and clothed with greyish pubescence. Second joint of 

 the flagellum distinctly longer than the third. Posterior ocelli 

 further from the eyes than from ea-ch other, separated frona the 

 eyes by a distance eqvial to about twice their own diameter ; eyes 

 about half as far again from each other on the clypeus as on the 

 vertex. Thorax closely and distinctly punctured. Median seg- 

 ment finely and closely punctured, with delicate, irregular, 

 oblique striae at the base, with a distinct median sulcus, but 

 without a carina, the posterior slope punctured, with indistinct 

 transverse strise and a strong median sulcus. Abdomen closely 

 microscopically punctured, the two basal segments slightly de- 

 pressed on the apical margin, the ventx-al segnrents more strongly 

 and sparsely punctured, the second and third ventral segments 

 more sparsely punctvired in the middle than at the sides. Second 

 abscissa of the radius fully as long as the petiole of the second 

 cubital cell, recurrent nervui^s interstitial with the transverse 

 cubital nervures.
