Fejnale with degenerate wings, unable to fly. Ovipositor 

 quite short and thick. The abdomen often rugose. 



Length, 3 7-9 mm., ? 10 mm.; wing, J 14-16 mm., $ 

 4 mm. 



Hah. Auckland to Christchurch. 



I give Mr. Kirby's description in full, but the colours of 

 the thorax and abdomen vary a good deal, many specimens 

 being unicolor. It can, however, always be recognised by the 

 pale ring behind the eye. The antennge are rather short and 

 stout. The wings are slightly smoky, except a transparent 

 mark on both sides of the stigma. The prgefurca is short, 

 forming less than a third of the second longitudinal 'vein ; 

 the petiole of the second posterior cell is long. The auxili- 

 ary vein is more or less blended with the first longitudinal. 



The eggs are laid in the ground, and the adult insect 

 ■emerges in April.

" Orange ; head orange ; antennae, palpi, and most of the 

 upper surface of the muzzle (which is moderately broad, 

 •obtuse, and set with short stiff bristles) blackish ; base of 

 palpi brown, a long black streak running forwards to a double 

 point from the middle of the vertex. Thorax orange ; front 

 of prothorax and first pleural sutures black ; a wide black 

 stripe on the back of the mesothorax, ceasing before the 

 lateral suture, and with a brown extension on each side in 

 front ; and two wide black stripes on each side, starting at 

 about one-fourth of the length of the mesothorax, and curving 

 towards each other, but not meeting, on the scutelluni, which 

 is wholly orange. Abdomen orange, with a black stripe on 

 the back widened at the extremity of each segment, a black 

 stripe on each side, and a central one (paler towards the base 

 ■of the abdomen) beneath ; legs black ; front femora yellowish 

 beneath. Wings hyaline, naked, iridescent, with short folds 

 along the outer half of the upper edge of the front basal cell 

 and along the lower edge of the hind basal cell ; veins brown ; 

 costal cells and stigma yellowish-brown ; first marginal and 

 first submarginal cells clear ; a triangular dusky spot extend- 

 ing to the inner side of the basal cross- vein ; halteres yellow, 

 with the clubs black" (Kirby). Length, <? 15mm.; wings, 

 J 19-20 mm. The female is unknown. 



Hab. Auckland and Wellington (Hudson). 



In none of my specimens is there a dark mark on the 

 vertex. The stigma and costal cell as far as the basal cross- 

 vein are dark-brown ; inside the basal cross-vein the costal 

 cell is clear. The auxiliary is completely blended with the
