TIPULIDiE. 



the anterior cross-vein, at a similar angle to that taken by the 

 4th vein in Musca and L^tcilia) until it meets the Isfc vein ; thence 

 running pai-allel to the costa and ending in it some little distance 

 before the tip of the A^ing. The 3rd vein, which runs nearly 

 straight to the exact tip of the wing, and the anterior cross-vein, 

 originate together from the angle in the 2nd vein where the latter 

 marks the end of the prsefurca, this section being longer than the 

 rest of the 2nd vein. Discal cell hexagonal, the lower half con- 

 sisting of three sides, the cell twice as long as broad and about as 

 long as the second and third posterior cells ; anterior cross-vein 

 shorter than proximal side of discal cell : postei'ior cross-vein just 

 beyond middle of discal cell ; 5th vein sharply angled at its juncture 

 with the posterior cross-vein, whence it runs straight to the wing- 

 margin ; 6th and 7th veins nearly straight. The 1st, 2nd, and 

 3rd veins near their tips are microscopically spiuose.

Section LUINOBIINI. 



Eyes bare, separated by a comparatively narrow frons. Proboscis 

 moderately long, elongate in at least one genus {Geranomijia) ; 

 terminal lamellse linear, narrow. Palpi four-jointed, slender, cylin- 

 drical. Antennae of 14 joints (sometimes apparently 15); scapal 

 joints of the usual type in Limxobiiinm: ; flagellum of oval or cylin- 

 drical joints, more or less pectinate in lihypidia. Genitalia of male 

 consisting generally of a pair of two-jointed claspers, the 1st joint 

 short, cylindrical or conical, the 2nd smaller, sometimes very much 

 so, bearing, or consisting of, a horny hook, a bitid claw, or similar 

 appendage. In the female the upper pair of valves may be shorter 

 than the lower ones {Dicranomyia) or subequal in length ; normal. 

 Legs more or less slender, stouter in Limnohia, long ; tibise without 

 spurs at the tip ; empodia indistinct or absent, ungues with teeth 

 on the underside.* AVings moderately bro-id, sometimes elongate, 

 with only one submarginal cell, four posterior cells, and the discal 

 cell closed or open. Auxiliary vein ending about the middle or 

 before two-thirds of the wing's length ; subcostal cross-vein near 

 its tip ; submarginal cell longer than 1st posterior cell. The 2nd 

 longitudinal vein usually begins a little before the end of the 

 auxiliai'y vein, the subcostal cross-vein being therefore sometimes 



* As I have not studied tbis character myself, I quote Osten Sackeii, who 

 gave it much attention : — "The teeth on the underside of the ungues of the 

 LiMNOBiNA seem to be pecuhar to this section. They must not be confounded 

 with the more or less square or sharjj projections on the underside at the very 

 basis of the \ingues, forming a part of the thickening which always exists there. 

 The tooth in the Limnobina, even when single, is distinct from this thickening, 

 and placed before it." Antocha was the only genus known to Osten Sacken 

 outside of the Limnobiini that possesses a form of this tooth.
