Schiner (Reise der Novara, Dipt. pp. 105-108) criticises Loew’s treat- 
ment of this family in the ^ Dipteren-Fauna Sud-Afiika’s.’ He objects to 
the adoption of IIi7-7noneu7'a as the typical genus of the family, and to the 
cons(!quent change of its naine to llmixoiwuridcc., and also to the division 
of tlie family into 2 sections, founded upon the length of the proboscis. 
Schiner enumerates the genera which have been established for the in- 
sects of this family, most of which he regards as badly constituted. Nerxxes^ 
trma he restricts to the species with the apex of the wing reticulated, and 
he separates from these the species {N. loxiyirosti'is and hrevi7'ost7'is, Wied.) 
which have the axillary cell divided by a transverse vein, to form the genus 
Mcyistox'hxjnclms (Macq.). Phxjnchocephalus (Fisch.) is a mixed genus ; N. 
tamchcri is taken as its type. The type of Ilirmoncxira is H. obseux'a 
(Meig.). Triclioplxthalma (Westw.) includes oil Macquart’s llivxnoncurcc 
with a long proboscis and densely hairy eyes. The South-African forms 
referred by Loew to MeyistorJujxiclms (Macq.) are placed in a new genus by 
Schiner. The number of previously described species is 80, of which only 4 
inhabit Europe, whilst America has 20, Asia 10, Africa 20, and Australia 19, 
and the habitat of 1 species is unknown. The number of genera accepted by 
Schiner is 11 (including his new genus).
