the segments, including the 1st, on which it is widest, but 

 excluding the last, with a blackish irregular band. Ovipositor in 

 the shape of two blades close together, orange-yellow. Belly 

 uniformly orange-yello\v. Legs : coxae lemon-yellow, the hind pair 

 having two small black spots on the hinder side at the base. 

 Femora and tibiae uniformly bright orange-yellow with minute 

 closely-set concolorous pubescence. Tarsi wholly coal-black. 

 Wings yellowish grey, costal cell yellow ; veins black. Halteres 

 yellow. 



Length 8 millim (without ovipositor).

Subfamily TIPULIN^. 



The TIPULIN.E are distinguished by the auxiliary vein ending 

 in the 1st longitudinal vein, and not in the costa. The humeral 

 cross-vein, close to the base of the wing, is the only cross-vein in 

 contact with the auxiliary vein, the subcostal cross-vein being 

 wholly absent. The 1st longitudinal vein nearly always turns 

 down into the 2nd and not upwards into the costa, the end of 

 the vein becoming much attenuated towards its tip. A small 

 cross-vein, which I propose to call the costal cross-vein, connects 

 the 1st longitudinal vein near its tip with the costa. The 

 2nd longitudinal vein has a short anterior branch that is nearly 

 perpendicular, and this joins the costa just beyond the costal 

 cross-vein, thus forming a small characteristic cell, known 

 as the rhomboidal cell (at first called by Osten Sacken the 

 trapezoidal). This cell is absent in Dolicliopeza owing to the 

 2nd longitudinal vein not being forked. The lower branch 

 of the 4th longitudinal vein forks at the inner end of the 

 discal cell, a little before it or towards the middle of that cell, 

 never beyond it ; the upper branch forks beyond, or at the 

 earliest, in contact with the distal limit of the discal cell. 

 The first longitudinal vein forks just after quitting the posterior 

 cross-vein ; this causes the ultimate posterior cell in such cases 

 to be pentagonal in shape, its inner end being always pointed. 

 The discal cell is nearly always pentagonal or hexagonal. 



A peculiar character nearly always visible in the TIPUXLN^E, 

 but especially noticeable in the genus Tipula, is what may be 

 termed, for want of a better name, the " obliterative streak," 

 running from the neighbourhood of the stigma nearly straight 

 across the wing, crossing the discal cell somewhere on its basal 

 half or about its middle, and disappearing soon after quitting 

 that cell. Osten Sacken refers to it as a " fold " of the wing. 

 Its effect is partially to obliterate, or at least to weaken, the veins 

 with which it comes in contact, and ils course is emphasized by
