This interesting dy belonss to the group of ?. pribilolensis
AlLrxander, T. subdrcli.d Alcxandcr and other species; thestructurc of thc ovipositor is very different from the othermembcrs oI t}re arctictt group, in {.hich the t€rgal valves areflattened, *'ith thc outcr margin scrratc. It is possible that
this fly is the female of the paratype specimen of T. sabarctica
from this region (see Report Canadian Arctic Expcdition,
Vol. III, part C, p. 16c; 1919) but jt now seems probablc that
this pamtype is not conspecific $ith the holotype from Camden
Bay, Alaska.

A paratype of this species was taken at Katmai in July,
1917; a second male from Savonoski, Naknek Lake, June, 1919
(Jas. S. Hine). As remarked under the discussion of the preceding species, this male may t'elong to TiPuIa t@nigaster.
