Although the first longitudinal vein terminates in this way, no trapezoidal 

 cell is formed ni-.-ir its extremity after tin- manner of the Tipulidae longipalpi, 

 hut this portion i> quite as in Dicranomyia 'I'he position of the auxiliary 

 vein is indeterminable from the fragment I have seen; but the "posterior 

 intercalary vein" of Loevv issues from the lower outer aii'_ r le of the di.scal 

 cell at a long distance from the great cross-vein, and in direct continuation 

 of tho fourth longitudinal vein. All these characteristics place it with the 

 Tipnlida- brevipalpi ; but the points wherein it differs from them, as nnleeil 

 from all other Tipnlidiu, are not a little extraordinary. Apparently it has 

 certain relations with theAmalopina, and has some resemblance to Symplecta, 

 lint it may he questioned whether it should not form a suction by itself in 

 the neighborhood of the Ptychopterina. 



The first longitudinal vein terminates in the upper branch of the second 

 at no great distance from the tip of the wing; at the same point it is con- 

 nected with the costa by an oblique cross-vein running in continuity with 

 its terminal portion. There are three submarginal cells and a secondary discal 

 'ill. The largo number of submarginal cells is due to the forking of the 

 posterior branch of the second longitudinal vein, just as two submarginal 

 cells are formed in Anisomera by the forking of the anterior branch of the 

 same vein. The secondary discal cell is formed by the division of the third 

 submarginal cell \>\- a cross-vein, which unites with the elbow of the h.i.-al 

 port ion of the lo\\er branchlet of the fork of the second submarginal vein, 

 and leaves t \\ o cells beyond the supplementary discal coll, just as there are 

 two i-.-ll- the first and second posterior) beyond the true di.scal cell; the 

 latter lies directly below the secondary discal cell, but is twice as large as 

 it. This is an anomaly quite unique, so tar as I am aware, among the 

 Tipulidse.
