1909] PuOCEEDINGS OF THE CLUB 19 



to form a deep wide groove on the outer face, upper margin distinctly serrate poste- 

 riorly, tip drawn out to a rather blunt twisted claw; lower valves somewhat sickle 

 shape, flattened, tip rather obtuse, longer than the upper valves but on account of 

 their position the tips not reaching beyond the middle of the latter. Length of 

 cT 4 mm., 9 6 mm., 15 cT 2 9 reared by Prof. H. J. Quayle, University of California,, 

 from larvae sent from Yuba City, Cal. Larvae reported as doing considerable dam- 

 age to roots of grasses. The size, general appearance, the length of the segments 

 of the palpi and other things seem to show close relation to the brevipalpi group but 

 the structure of the hypopygina leads me to place the species in the genus Tipula 

 for the present at least.
