HuTTON. — On the Crane-Jiics of New Zealand. 37 



brown ; a clear round spot in the base of the submarginal 

 cell, and a clear space occupying most of the first posterior 

 and discal cells. First longitudinal vein arcuated, but joining 

 the costa obliquely. Posterior cross-vein ni a line with the 

 inner margin of the discal cell. Joints of the fiagellum of the 

 antennae slightly cyathiform in the male, oval in the female. 

 Length, S- 14mm.,? 11mm.; wing, $ 20mm., $ 14mm. 



Hab. Wellington (Hudson). 



I have not adopted Mr. Hudson's name for this species, 

 because the wings are not smoky, and because we have 

 already in New Zealand a Limnohia fmnivennis which might 

 cause confusion. 



Trochobola picta, sp. nov. Plate III., fig. 11. 



Yellowish-brown, darker below ; mesonotum pale, with a 

 narrow dark central line and a broader one ou. each side, 

 passing from the head to above the wings ; the tip of the 

 scutellum and the metanotum dark-brown. Legs pale, with 

 a dark ring near the distal end of each femur. Wings trans- 

 parent, with numerous dark-brown spots ; three near the 

 costa. Of these the first is situated at the base of the 

 anterior basal cell, the second at the origin of the second 

 longitudinal vein, and the third round the stigmatic area ; the 

 latter is the largest of the three, and extends along the costa 

 from inside the tip of the auxiliary vein to the tip of the first 

 longitudinal ; it also extends backwards to the base of the 

 first posterior cell. Near the costa it contains some pale 

 spots. The rest of the wing has numerous small brown spots, 

 and larger ones at the apices of the first and fourth posterior 

 cells, as well as in the anal and auxiliary cells. Posterior 

 cross-vein in a line with the inner edge of the discal cell. 

 Joints of the fiagellum of the antennae cyathiform. Length, 

 (J 10 mm. ; wing, 3- 12nmi. The female is unknown. 



Hah. Wellington (Hudson). 



In both my specimens the discal cell is irregular, the 

 cross-vein at the base of the second posterior cell being placed 

 outside its usual position, so as to make that cell about half 

 the length of the third posterior. 



Genus Ehamphidia, Meigen (1830). 



" One submarginal cell ; four posterior cells ; a discal cell ; 

 no marginal cross-vein. The tip of the auxiliary vein is at 

 some distance beyond the origin of the second longitudinal ; 

 the subcostal cross-vein is close to its tip. Eostrum elon- 

 gated, but shorter than the thorax ; last joint of the palpi 

 elongated. Antennte 16-jointed. Tibiae without spurs at the 

 tip ; empodia indistinct ; ungues smooth. The forceps of the 

 male very like that of Elephantomyia" (Osten-Sacken).
