OA? New Western Tipula 43 
rather long somewhat curved process the black tip of which ends in two 
short points; first pair of appendages spatulate, second pair broad, flat- 
tened, twisted and ending in two short black tips the upper one of 
which is longer, broader and triangular; wings hyaline; stigma brown; 
the indistinct whitish line not reaching the base of the fourth posterior 
cell. 
Female: First and second joint of antennez yellow, third and 
sometimes the fourth somewhat yellowish, others brown; eighth tergite 
a little shorter than the seventh; eighth sternite about as long as the 
seventh; posterior margin witha crescent-shaped incision and depressions; 
the apical appendages, corresponding to the lower valves of the ovipos- 
itor, are short, quadrate, upper margins more strongly chitinized with 
the edge twisted or rolled, posterior margins with sharp-pointed trian- 
gular processes ninth tergite about half as long as eighth; tenth tergite 
narrow, about twice as long as ninth ending posteriorly in a pair of 
short, round-tipped lobes, beneath which is a broad, short, unchitinized 
appendage which also ends in a pair of short lobes similar to those above; 
ninth sternite, lying above the eighth sternite, consists of two strongly 
chitinized lateral plates which are united posteriorly into a rather long 
sharp process. Length, male 9 mm.; female 11 mm., wing 10 mm.
