Australasian Species. By CHAI~LES P. ALEXANDER, Ph.D.,
F.E.S., Massachusetts Agricultural College, Amherst,
Massachusetts, U.S.A.
IN the present paper the writer has begun the considerationof the Australian and Tasmanian species of the genus
Molophilus, a large and varied aggregation of small to
medium-sized :Eriopterine crane-flies.
The group here
attains its maximum of species, a condition that is scarcely
approached ill any other country, with the single exceptionof New Zealand. The numerous new species that aredescribed at this time and in succeeding instalments under
this title fall naturally into three large groups that are
differentiated on characters of the male hypopygium. I tshould be noted in Molophilus, as well as several other generaof Tipulidm, that the ninth segment of the abdomen of themale has undergone a torsiou of 180 °, so that the tergite
occupies a ventral position. In the accompanying descriptions all characters and directions are morphological rather
than apparent. The specie~ described in this paper are
mostly members of the plagiatus group, strongly developed
iu New Zealand as well as in Tasmania and Australia. ]=[erethe ventral lobe of the basistyle (fig. ], v) of the male hypopygium is the only one preserved, produced caudad into alobe of varying length, the mesal face before apex armed
with a small chitinised beak.
The majority of the species of Australian Molophilus
available for study at this time were collected in Tasmania,
Victoria, and New South Wales by Dr. Andr6 Tonnoir, tonew or little-known T i p u l i d m .
