274 TIPULIDJK. 



bescent, curved downward; joints of nearly equal length. Antennae 

 sixteen-jointed, porrect, simple, somewhat hairy, filiform, or nearly seti- 

 form ; first joint cylindrical ; second cyathiform ; the rest small and 

 oval. Thorax with a sinuated transverse suture. Wings incumbent, 

 parallel, rather long, of moderate breadth, very generally pubescent ; 

 mediastinal vein joining the costa at two-thirds of the length ; subcostal 

 ending at rather beyond three-fourths of the length ; radial and cubital 

 springing from a common petiole, which proceeds from the subcostal 

 before one-third of the length of the wing, exceeds them in length, 

 and is connected at its fork with the subcostal by a transverse veinlet ; 

 first externo-medial proceeding from the above petiole near its fork, 

 connected at an angle near its base with the third externo-medial by a 

 transverse veinlet ; the latter also forms an angle, whence proceeds the 

 second externo-medial, which is forked at about two-thirds of its length ; 

 another veinlet, opposite the above-mentioned, connects the third externo- 

 medial with the subanal. Halteres elongated. Abdomen with eight 

 segments, minutely pubescent, nearly cylindrical or nearly fusiform. Legs 

 long, slender, somewhat pubescent, unarmed ; the middle pair some- 

 what shorter than the others ; tibiaB without spurs. Male. Tip of the 

 abdomen obtuse. Fern. Abdomen with two horny styles at the tip. 



The larvse live under the earth, and the flies inhabit shrubs and 

 woods, meadows, marshy places, and heaths.
