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

 4th vein in Musca and LuciUa) until it meets the 1st vein ; thence 

 running parallel to the costa and ending in it some little distance 

 before the tip of the wing. 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 praefurca, 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 ; posterior 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 LIMNOBIINI. 



Eyes bare, separated by a comparatively narrow frons. Proboscis 

 moderately long, elongate in at least one genus (Geranomyia) ; 

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

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



llum of ov 



joints of the usual type in LiMyoBiix.i; ; flagellum of oval or cylin- 

 drical joints, more or less pectinate in liJiypidia. 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 bifid claw, or similar 

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

 than the lower ones (Dicranomyici) or subequal in length ; normal. 

 Legs more or less slender, stouter in Limnobia, long ; tibiae without 

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

 on the underside.* AVings moderately broad, 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 ; subraarginal cell longer than 1st posterior cell. The 2nd 

 longitudinal vein usually begins a little before the end of the 

 auxiliary vein, the subcostal cross-vein being therefore sometimes 



* As I have not studied this character myself, I quote Osten Sacken, who 

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

 LIMNOBINA seem to be peculiar to this section. They must not be confounded 

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

 basis of the ungues, 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.
