Tipula (Yaruatotiptla) Ianei is narnedin honor of the collector,
Mr. Merton C. Lane. It is allied to T. (Y .) spernar Osten
Sacken,differing in the small size, darkenedwings, and the structure of the male hypopygium, as the very low and broad median

YamatotipulaMatsumura, the assignmentbeing made especiallyon
the structure of the ninth tergite and gonapophysesof the malehypopygium.

Para'Linmophila (Prionolabis) oregonensisis readily distinguishedfrom the other small western Nearctic Prionolabi,sL. (P.)

r9oo. Linmolthila nigrilinea Doane; Journ. N. Y. Ent.
Soc.,8: r9o, plate 8, fig. z (venation).
The uniquetype, a female,was from Olympia, Washington,now
preservedin the United StatesNational Museum. A male specimen at hand shows that the speciesis not a Li,nutophilabut amember of the genus Lipsothrir Loew, where it is well-distinguishedfrom the approximatelyone dozen specieshitherto madeknown by the very large size and, especially,by the conspicuous
macrotrichiain the cells of the distal fourth of wing. I describe
this male as allotype.
Allotype.-Il[ale: Length about I I mm. ; wing 12 rnm.; antenna
about 4 mm.
Antennae relatively long, as shown by the measurements;
flagellar segmentscylindrical; verticils short, much shorter
than the segments.Head obscureyellow,the occiputdarkened.

I take great pleasurein naming this fly in honor ol my former
student, Mr. John W. Zukel, to whom I am indebtedfor several
interestingTipulidae from Idaho.
