316 TIPULIDjE. 



stigma ; radial connected with the subcostal by a transverse veinlet at 

 the tip of the stigma ; cubital connected with the third externo-medial 

 by a transverse veinlet ; the angle of the latter emits the first externo- 

 medial, which is forked before one-third of its length, and its fore fork 

 is again divided at two-thirds of the length ; third externo-medial con- 

 nected with the subanal by an oblique veinlet, which is nearer than the 

 veinlet in front to the tip of the wing ; subanal vein and anal vein 

 complete. No discal areolet. Halteres long. Abdomen with eight 

 segments, slender. Legs long, slender, unarmed ; femora and tibiae of 

 nearly equal length ; tarsi very long, almost twice the length of the 

 tibire. Male. Antennae rather longer than the head and the thorax. 

 Fern. Antennae rather shorter. 



The only known species of this genus may be at once distin- 

 guished from all the other British Tipulida by its long and very 

 slender white tarsi.
