costal and subcostal cells yellow ; stigma dark brown ; a brown mark 

 at the arculus; veins dark brown; obliterative streak broad, ex- 

 tending into the base of cell M *. 



Abdomen with the tergites yellowish; a broad, dark brown 

 median stripe that is interrupted at the posterior margins of the 

 segments; a narrower sublateral stripe; sternites yellow. Male 

 hypopygium moderately enlarged. Ninth tergite large, the caudal 

 margin shiny with a very deep notch at the base of which is a 

 small, acute median tooth; lateral angles prominent, flattened, 

 subacute and slightly divergent at their apices. Ninth pleurite 

 complete or practically so; outer pleural appendage small, cylin- 

 drical, covered with long, coarse hairs; inner pleural appendage 

 complex, produced posteriorly into a pale, flattened, truncated 

 lobe that is covered with abundant pale hairs, the anterior arm 

 heavily chitinized, the tip bifid and jutting into the notch of the 

 tergite. Ninth sternite with two pendulous lobes hanging in the 

 notch, these lobes narrowed toward their outer ends. Eighth 

 sternite with the posterior margin concave, the median portion 

 with a dense, transverse fringe of long, yellow hairs, near each 

 lateral angle with about two powerful decussate bristles. Penis- 

 guard very elongate, the tip split into two hair-like points. 



The female is similar to the male; antennae short; abdomen 

 with the dorso-median stripe lacking, the posterior margins of the 

 segments broadly ringed with pale; ovipositor with the valves 

 acute, compressed, the tergal valves longest, blackened at their 

 tips.

In the peculiar antennae, this interesting species agrees with 

 T. tephrocephala Lw., but in all other respects is a very different 

 fly. 

 Tipula flavo-umbrosa, new species. 



Male. — ^Length 22 mm.; wing 21.5-22 mm.

Very similar to Tipula umhrosa Lw. {inermis Doane) but
