DIPTKRA. 321 



Pedicia, Lat., 

 Where they are almost setaceous and simple, with the two first 

 joints largest and elongated, the three following ones tuibinated, the 

 next three globular, and the seven last slender and almost cylindri- 

 cal *. 



TiPULA, Lat.^ 

 Where the antennae are short, setaceous, and simple, hut where 

 all the joints, the second one excepted, which is almost globular, are 

 nearly cylindrical ; the first is the largest, the third elongated. 



T. oleracea, L. ; De Gecr, Insect., VI, xvi, 12, 13. Antennae 

 simple ; body greyish-brown, and immaculate ; Avings light- 

 brown, darker on the external margin. Very common in 

 meadows on the grass. The larva feeds on the roots of decom- 

 posed plants f . 



Nephrotoma, Meig., 

 Where the antennse are still simple, and almost setaceous, with the 

 first and third joints elongated and cylindrical, and the following ones 

 arcuated; those of the males consist of eighteen, the females have 

 but fifteen. This number is never exceeded in the preceding sub- 

 genera, even in the males |. 



Ptychoptera, Meig.y 

 Where those organs are always simple, and nearly setaceous, con- 

 sisting of sixteen joints, the third of Avhich is much longer than the 

 others, and the following ones oblong. Tlie li])s of the proboscis are 

 inclined, and very long §. 



In all the following sulgenera the last joint of the palpi is hardly 

 longer than the others, and presents no appearance of annular divi- 

 sions. The wings arc frequently incumljcnt, one on the other. 



Here the antennoe have more than ten joints. 



Those in which they are mostly granose, of equal thickness, or 

 hardly smaller at the extremity, and frequently furnished with 

 whorls of hairs, according to Meigen, form various genera. 



Rhipidia, Meig. 

 The only Tipularite of this subdivision in which the antennre of 

 the males are pectinated |!. 



Eriopetra, Meig. 

 Several nervures in the wings, as in those of the preceding Ti- 

 pulae, but covered with hairs ^. 



Lasioptera, Meig., 

 Where the wings are also hairy, but present only two nervures **,

 unites them with the Limnobiw. See Encyc. Method., article Pedicie,
