In an earlier paperl I have listed the Tipulidae known from the Marquesas Islands. Recently I have received through the kindly interest ofE. P. Mumford a still further species,collectedby Messrs.G. Le Bronnec
and H. Tauraa. I wish to express my deep thanks to the above-namedentomologists for their continued efforts toward making known the crane-fly
fauna of theseislands. The type is preservedin BerniceP. Bishop Museum,Honolulu.

basistyle;d: dististyles;9: gonapophyses.

Gonomyia (Lipophleps) lyra, new species(fig. r).
General coloration reddish yellow to yellow; antennal scapeand pedicel yellow, theflagellum darker; thoracic pleura with a conspicuousblack stripe; halteres pale yellow;
legs yellow, the femoral tips broadly and conspicuouslyblackened; wings clear yellow,
with a narrow brown seam on anterior cord; aMominal tergites bicolorous, reddish
brown, the caudal margins narrowly more yellowish; lateral margins of aMomen blackened; male hypopygium with the gonapophysestogether appearing narrowly lyriform,
each arm terminating in an acute spine but without a lateral branch.
Male: lengh about 5-5.5 mm; wing, 3.8-4.emm. Female: length about 5.5-6 mm;
wing,4-4.Smm.
Rostrum and palpi black. Antennae with the scapeand pedicel dull orange; flagellum yellowish brown. Head yellow.

Pronotum yellow. I\fesonotal praescutum reddish yellow, the lateral margins clear
pale yellow; posterior sclerites of notum pale, the scutal lobes darker, especially near-.."i borders. Pleura whitish, with a broad brownish black dorsal stripe that extends
from the propleura to the abdomen,the ventral sternopleuritepale yellow. Halteres paleyellow. Legi with the coxae and trochanterspale yellow; femora yellow, the tips broadly
and conspicuouslyblackened,the amount of darkening subequalon all legs; tibiae yellow,
the tips- t.ry n"irowly and vaguely darkened; tarsi yellow, the terminal segmentsdarkened. Wings (fig. r, o) clear yellow, the stigma pale; a narrow brown se.unon anteriorcord, best ividenced by a darkening of the veins traversed; remaining veins yellow.
Venation: Sc, ending oppositeor just before origin of Rs, the latter arcuated; cell tst
Mr closed; m-cu at or some distance before the fork of M.
Affiominal tergites bicolorous, reddish brown, the caudal margins narrowly moreyellowish; sterniteJobscure yellow, the basal segmentand lateral borders broadly blacklned. Male hypopygium (fig. r, b) almost as in G. od,amsonibut differing conspicuously
in the gonapophyies,which here appear narrowly lyriform, each approximated at base,thence ,fighlty divergent, the tip suddenlynarrowed into an acute spine that is surroundedby numerousdelicati setulae; mesal edge of arm of apophysismembranousand fringed
with delicate setulae.

Nukuhiva: Taiohae, June 4, 1930, at light (Le Bronnec and Tautaa);
holotype,male; allotopotype,female; paratopotypes,severalof both sexes.
Gonomyi,a(Lipophleps) lyra is very closeto G. (L.) adomsoniAlexander(Marquesas: Eiao) which is most readily told by the more brownish yellow
wings and by the structure of the male hypopygium, especiallythe lateral spineon each gonapophysis.
