THE CANADIAN ENTOMOLOGIST 171 



Mesonotal privscutum light grey with four brown stripes, the intermediate 

 pair becoming indistinct anterior to the level of the pseudosutural foveic; scutal 

 lobes largely brown; scutcdum and postnotum light grey. Pleura grey, clearer 

 and lighter posteriorly. Haltcres brown, the extreme base yellow. Legs 

 with the cox?p light grey; trochanters light yellow; femora yellowish basally, 

 soon passing into brown, the tip narrowly darker brown; tibiae with the basal 

 half light brown, the apical half darker brown; tarsi dark brown. Wing pattern 

 and venation about as in T.fragilis, the stigma paler brown. 



Abdomen with the first tergitc grey pruinose, the other tergites brown 

 with a broad, dark brown sublateral stripe, ringed posteriorly with yellowish, 

 these rings broadest on the basal segments, becoming indistinct about the 

 seventh segment; sternites one to five bright yellow, the basal segments a little 

 darker laterally; remaining sternites dark brown. Male hypopygium with the 

 ninth tergite rather large, divided into two apparent halves by a mid-dorsal 

 impression; each half is produced caudad into an inner flattened lobe, separated 

 from its mate of the opposite side by a very small and narrow notch, the lateral 

 angle of each lobe slightly produced and with a few stout black setae; the tergite 

 is dark, the lateral margins yellowish, the apical lobes orange yellow and pro- 

 vided with a short, dense pubescence. Outer pleural appendage large, greyish, 

 slightly curved, the outer face with appressed black hairs; near the base of the 

 appendage a shiny, flattened, chitinized tooth. Inner pleural appendage com- 

 pressed, flattened, extensive, near its base forming a cup-like hollow. An 

 enlarged, dark-coloured, fleshy lobe provided with numerous pale hairs lies on 

 either side near the ventral angle of the pleurite, extending dorsad along the 

 opening of the genital chamber; the outer basal margin of this lobe is light yellow 

 in colour. Eighth sternite slightly projecting, the posterior margin with a large, 

 shallow, broadly U-shaped notch, the lateral angles of which are provided with 

 long whitish hairs, the outer basal margin of this lobe minutely spinulose, light 

 yellow beneath.

Tipula fragilina, new species. 



Belongs to the marmorata group, closest to T.fragilis Lw.; legs darkened, 

 the femora with a broad, yellowish subterminal ring before the black tip; male 

 hypopygium having the ninth tergite with a wide V-shaped notch; outer pleural 

 appendage with a blunt, blackened basal lobe; eighth sternite carinate, the 

 posterior margin with a very deep and narrow median notch, the margins con- 

 tiguous or nearly so and provided with long, yellowish hairs.

Female. — Length about 13 mm.; wing 13 mm. 



Generally similar to T.fragilis Lw., difl'ering as follows: The intermediate 

 stripes of the prsscutum are broader and extend further cephalad; the ground 

 colour between the intermediate and lateral stripes narrower. Pruinosity of 

 the pleura darker. Legs darker, the black femoral tips broader and with a
