THE CANADIAN ENTOMOLOGIST. 209 



densely covered with long hairs, these hairs rather stout except 

 along the caudal margin where they are delicate, fringe-like; just 

 inside this appendage is a cylindrical, chitinized arm directed 

 toward the end of the 9th tergite, the apex evenly rounded ; the 

 largest of the pleural appendages is a flattened arm whose apex is 

 notched and crenulated and fits into the notch of the 9th tergite; 

 the penis is very long and slender, the central vesicle large and 

 rounded. 



Female. — About as in the c?, the flagellar segments suban- 

 nulate, the apical three-fifths of each segment being much paler 

 than the basal portion; abdominal tergites 5-7 with a dark brown 

 basal mark, segments 8 to the end brown; valves of the ovipositor 

 short and sharply pointed. In one 9 , the entire tergum beyond 

 segments 1-3 is almost entirely dark brown but this may be caused 

 by the gravid condition of the abdomen which is greatly distended 

 with eggs.
