anal, axillary and spurious cells, one or two of which reach the posterior margin of 

 the wing ; an indistinct brownish border along the distal portion of the fifth vein ; 

 a brown spot over the basal cross veins ; discal cell more than twice as long as wide. 

 Length, male 19 mm., female 22 mm., wing 19 mm. 



Habitat : Collins, Idaho, two males. (Type) Moscow Mt., Idaho,

The specimens from Keyport are larger with the general color of 

 the body yellowish instead of brownish in all but two females, where 

 the thorax is grayish, the wings are more yellowish with the white 

 markings more distinct. These may possibly represent a distinct 

 species, but as they show so much variation a larger series will be 

 needed before the constant differences, if any, can be determined. 



Tipula acuta, sp. nov. 



Brown ; head grayish-brown with a faintly indicated brownish line above ; ros- 

 trum reddish-yellow, grayish-brown above ; palpi brown, darker toward the tip ; 

 antennae not reaching the base of the wing, first and second segments and the basal

 brown with three brown stripes, the lateral ones much broader posteriorly ; posterior 

 margin of the eighth sternite with a rather deep rounded incision from the middle of 

 which arises two tufts of long yellow hair and from the sides of which arises a pair of

 brown, valves straight, acute ; wings with a brownish singe which is somewhat 

 darker in the subcostal cell and in the anterior margin of the anal cell ; stigma brown ;
