On a neio Genus of Scatopsi'd Flies. 207 



Body partly naked behind, both above 



and below II. Liponycteris, gen. nov. 



Ueuotype: L. nudiventris {T. nudiventris, Cr.). 



B. Bullae perfect internally. No radio- 



met;icaq)al pouch. Body hairy III. Saccolaimus, Less. 



Genotjiie: S. saccolaimus {T. saccolaimus, Temm.). 



Besides nudiventris, Liponycteris would contain only 

 kachhensis and its two subspecies — inagam*, Wettstein (1914:, 

 syn. habylonicus, Tlios., 1915), and 7iudasler, Thos. 



XXXIII. — Preliminary Note on a new Genus of Scatopsid 

 Flies from New Zealand. By F. W. Edwards. 



(Published by permission of the Trustees of the British Museum.) 



Among a large collectton of Tipulidre 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 Scatopsidaj. I hope 

 to give a detailed account of this fly in a future paper on the 

 Mycetophilida?, Bibionidse, and Scatopsidse 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, Bohemann, in wing-venation and 

 in the strongly clubbed hind femora and curved hind tibiie, 

 but differs as follows : — Anteinise fully as long as the head 

 and thorax together (rather longer in J 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 o£ the segment. Claws 

 much enlarged at the base, the enlargement bearing a row of 

 fine teeth (df ? ). Empodia present, very large, broadening
