three-fourths the length of the second. There is a stump at 

 the angle of the prsefurca. The posterior cross-vein enters 

 the discal cell at about three-quarters of its length from the 

 hind margin. Length, 3- 12 nun. ; wing, S 13 mm. The female 

 is unknown.

In this species, like the two last, the tibial spines are 

 short, and pass below the metatarsus. The empodia are dis- 

 tinct. The antenntE are 16-jointed ; the joints of the flagel- 

 lum cylindrical. ' 



Genus Tinemyia, gen. nov. 



Two submarginal cells ; five posterior cells ; a discal cell ; 

 subcostal cross-vein beyond the origin of the second longi- 

 tudinal. Wings and eyes glabrous. Antennse 16-jointed. 

 Eostrum longer than the head and thorax together, the palpi 

 near the tip. Tibiae with short spurs. Empodia indistinct or 

 none. Ungues smooth. 



Notwithstanding its short tibial spurs, which are less than 

 the breadth of the tibia, the venation of the' wings shows that 

 this genus belongs to the Limnopivilina. I have only seen a 

 single female specimen, and so can give no account of the 

 forceps of the male.

Brown, the tips of the first six joints of the flagellum of the 

 antennse and the whole of the last joint pale. The knee-joints 

 are also pale. Antennas long ; the first joint short and stout, 

 the second cyathiform, those of the flagellum cylindrical, ex- 

 cept the last, which is oval, and broader than the others. 

 Eostrum twice as long as the head and thorax taken together ; 

 the palpi sbort, 3-jointed. Halteres very long, brown. The 

 ovipositor pale at the tip. Wings brown, with numerous small 

 pale-yellow spots and lines. About nine spots, either circular 

 or semicircular, in the costal cell ; a larger one crossing the 

 second subcostal and first submai'ginal cells ; another in the 

 second mai'ginal. Others in the middle portion of the wing, 

 chiefly as short straight or curved cross-streaks. Four round 

 spots in the anal cell. Veins fuscous. Subcostal cross-vein 

 close to the tip of the auxiliary. Fu'St submarginal cell about 

 three-fourths the length of the second. Posterior cross-vein 

 entering the discal cell at about one-third of its length from 

 the inner margin. Length, J 15 mm.; wing, J 14 mm.; 

 antenna, $ 4 mm.; rostrum, $ 6 mm. The male is un- 

 known.
