1921] Dietz:. Impudica Group of Tipula 13 
lanceolate. Ninth sternite deeply and broadly emarginate, margin of 
the emargination and lower margin of the somite pale yellow. Pleurites 
subtruncate above; inner apical appendages bent upward anteriorly, 
the evoluted portion small, but distinct; lower apical appendages

dorsad, tongue-shaped, fuscous. 
Holotype— oo. Silver City, New Mexico, June 1, 1911. 
At once distinguished by its small size. Superficially it 
~resembles tmpudica and mitrata, from both of which it differs 
in the faint ante-stigmal spot, aside from structural differences 
of the hypopygium.
