scant space for the auxiliary vein. The legs are long and slender, 
with exceptionally long tarsi. 
Both from their size and the brevity of the preefurca it is tolerably 
plain that both the unnamed species from the upper oligocene of 
Brunstatt, referred by Foerster (Adhandl. Specialk. Elsass-Lothr., 
ill, pl. xiv, figs. 2, 3) to Tipula, are to be considered as belonging 
to the present genus. 
Four species are known from Florissant, which may be separated 
by the following table: |

Wings generally four times as long as broad sometimes a little 
less than that, in one instance (No. 11686, which may possibly not 
belong here) only three and a half times as long as broad, 
uncolored, except for the stigma. The inner marginal cell is 
pretty regularly fusiform, about three times as long as broad. The 
discal cell is also about three times as long as broad, and of just 
about the size of the inner marginal cell. The petiole of the 
second posterior cell is usually about half as long as the discal cell, 
but sometimes not more than one third as long, while the second 
posterior cell itself is about half as long as the whole of the inter- 
sected apical area of the wing, which, measuring from the end of the 
basal cells, is about equal to the breadth of the wing. The fifth 
posterior cell is considerably wider at base than just before the 
margin. The sixth longitudinal vein is moderately distant from the 
fifth. Legs very long and slender, the femora nearly three fourths 
as long as the wings, the tibiz scarcely longer and a little slenderer, . 
the tarsi two thirds as long again as the tibie. Abdomen rather 
heavily traversed by dark bands at the apices of the segments,
