TIPULIDiE COLLECTED BY THE UNIVERSITYOF IOWA FIJI-NEW ZEALAND

EXPEDITIONCharles P. Alexander
Amherst, Massachusetts

The crane-flies collected by the 1922 Expedition of the Universityof Iowa to Fiji and New Zealand have been submitted to the writerfor determination through the kindness of Professor Dayton Stoner.

The specimens, including the type of Limonia stoneri, have beenreturned to the University of Iowa. For convenience of treatment,
the fauna of Fiji is considered separately from that of New
Zealand, since there is no relation between the two.

FIJI

The crane-flies of the Fiji Islands are still imperfectly known,
upon them being two by the writer. 1
The fauna shows a marked endemieism though clearly derived fromthe only published papers

the larger land masses lying directly to the eastward.

The present collection included three species of the tribe Limona group which is extremely abundant in number of species
throughout the Oriental and Australasian Regions.

Limonia Meigen;

The center of distribution of the great genus Limonia appears
from whence it has spread toalmost all of the major land masses of the world. In the presentcollection, a single species was included which is herein considered

to be the palaeotropical region,

as being undescribed.

Limonia stoneri, sp.n.
General coloration light yellow; pronotum darkened medially; head brownish black; legs yellow, the tips of the femora conspicuously blackened; abdominal tergites obscure brownish yellow, each with a transverse central bandof dark brown, sternites dark brown.
F&male.
Length about 10 mm. Described from an alcoholic specimen.
Eostrum brown; palpi dark brown. Antennae with the scape dark brown;
flagellum paler brown, the basal segments with the proximal portion yellowish.
Head brownish black.
Pronotum yellow, dark brownish medially. Mesonotal praeecutum andscutum yellowish, the former very narrowly and indistinctly darkened anteriorly; scutellum light yellow with a small brown spot on either side of themedian line at the base; postnotum yellow, the basal median region more orless darkened.
Pleura yellow. Halteres yellow, the knobs dark brown. Legs;
with the coxae and trochanters yellow; femora yellow, the tips rather broadly
and conspicuously blackened; tibiae obscure yellow, the tips very narrowly
darkened ; tarsi obscure yellow. Wings badly injured and their characters
can be defined in general terms only; general coloration pale brown, the costal
region more yellowish ; stigma relatively small, oval, dark brown veins darkbrown, those in the costal region more yellowish. Venation: Sc long, Scialone a little longer than the distance between the tip of Sci and the proximal
end of Bs.

NEW ZEALAND
The crane-fly fauna of New Zealand is now known to be an
At the time of the signing of thearmistice in 1918, the total number of species of Tipuloidea
described from New Zealand was less than fifty. Since that time
there has been great activity among collectors and a very considerable number of additional species have been described, chiefly
by Edwards and the writer. The number of species now known
from New Zealand is not less than 350 and the number will be still
further augmented with additional collections. The present collection includes only 9 species but this must be considered as being
a fair representation of the fauna on the wing at the time thecollections were made.
The published records for Auckland arevery poor and the present list adds several species to the list fromextremely rich and varied one.
