UNDESCRIBED OR LITTLD-KNOWN CRANE_FLIES FROM
THE PACTFTC TSLANDS (TrPULIDtts" DTPTERA).
By Cnenrns P. Arpx,t\DER, Urbana, Iliinois.
Through the kindness of Prof. R. W. Doane and Mr. F. R.
Cole, the writer was able to examine the crane-fliescollectedby
Pro{. Doane in Tahiti in rgo8, in Sanoa in r9r3, and by Prof.
V. L. Kellogg in the latter island in rgoz. The result of thisstudy has considerably extended our rather scant)r knowledge of
the Tipulide of oceanicislandsalthough the main f eaturesof distribution are unmodified. The rvriter rvishes to thank Prof.
Doane and Mr. Cole for the privilege of studying this material.
The t1'peshave been returned to Prof. Doane.

This curious flv is not a typical member of the genusRhipidia
but from the unique structure of the antenne it is placed in thisgroup, at least provisionalll'. It is named in honor of the memoryof Robert Louis Stevenson," Tusitala," r,ho spent the last few
years of his life in Samoa ancl is buriecl near the type-locality.
R. debeauforfi (1\'[eijere)is another member of this group.
Doaneomyia gen. n.
Related to Dicranontyiz but distinguishedfrom this genus
as lvell as all others in the family Tipulide by the presenceof a single anal vein. Antennre r4-segmented. Tibie without spurs; claws long, simple, almost straight. Vein Sc isshort, with Sc, not far removed f rom the tip of Sc, ; Rs andthe basal deflection of R',r" in alignment and subequal; cell
tst M, open by the atrophy of the outer deflection of M"ionlv the rst AnaI vein preserved; no vestige o{ the atrophiedvein ir.nmediateli'behind vein Cu; a long basal wing-petiole.
