XXXII.—Preliminary Note on a new Genus of Scatopsid 
lies from New Zealand. By F. W. Epwarps. 
(Published by permission of the Trustees of the British Museum.) 
AmonG a large collectton of Tipulide recently sent me for 
study by Mr. G. V. Hudson, of Wellington, New Zealand, 
were several specimens of a very remarkable fly, which must 
be placed in a new genus of the family Scatopside. I hope 
to give a detailed account of this fly in a future paper on the 
Mycetophilide, Bibionidz, and Scatopside of New Zealand, 
but, meanwhile, at Mr. Hudson’s request, I offer preliminary 
diagnoses of the new genus and of three new species. The 
great interest of the new genus lies in the fact that its only 
relative (not a very close one) is Corynoscelis—a very rare 
fly, of which only a single species is known from Arctic 
Europe. 
CANTHYLOSCELIS, gen. nov. 
Resembles Corynoscelis, Bolemann, in wing-venation and 
in the strongly clubbed hind femora and curved hind tibize, 
but differs as follows :—Antenne fully as long as the head 
and thorax together (rather longer in g than in ? ), the joints 
well separated, with short pedicels, longer than broad, and 
somewhat flattened. Only two ocelli present, placed close 
together some little distance behind the eyes. Club of hind 
femora larger, occupying two-thirds of the segment. Claws 
much enlarged at the base. the enlargement bearing a row of 
fine teeth (¢ 2). Empodia present, very large, broadening
