TITVLIDJE. 



conspicuously pubescent ; ungues apparently smooth, empodia 

 small but very distinct. Wings comparatively short and broad, 

 very clear except in the parts ornamented by brown bands ; veins 

 very distinct ; stigma generally short and rounded, or indistinct. 

 One submargiual cell, four posterior cells, and a discal cell ; 

 auxiliary vein ending about the middle of the wing, a little before 

 the tip of the 1st longitudinal ; the 2nd longitudinal vein begins 

 considerably before the middle of the wing, the prtefurca generally 

 curved, sometimes nearly straight, about equal in length to or 

 much shorter than the rest of the vein ; marginal cross- vein 

 placed at about the middle of the marginal cell, uniting it with 

 the 1st longitudinal vein near the tip of the latter ; niarginal 

 cross-vein, base of submargiual cell and anterior cross-vein often 

 more or less in a hue, less so in the Oriental species ; the 3rd 

 vein gently curved ; discal cell elongate, broader distally than 

 proximally ; posterior cross-vein near the base of the discal cell, 

 approximately opposite the anterior cross-vein, and placed a little 

 forward or backward, according to the species ; the 5th and 6th 

 veins straight or nearjy so, the latter sometimes slightly bisinuate, 

 7tli gently curved. 



Range. India, Ceylon, United States, Mexico, West Indies, 

 Brazil, and Australia. 



The species of this genus have a facies peculiarly their own, 

 and amongst a general collection of Tipulid.i: can easily be 

 recognised, once the genus is understood. Their well-set, robust 

 appearance, subgibbous thorax, long neck, comparatively short, 

 robust hairy legs, very clear wings (in the hyaline parts), short 

 auxiliary and 1st longitudinal veins, with the general distinctness 

 of all the veins, characterise tliem as a well-detined, homogeneous 

 group.
