384 DIPTERA 
Bicellaria aterrima Roser in part is probably sPuria Fallen, and in part is Aelestus julicarius Fallen, of 
the Platypezidz. 
Bicellaria tibialis Roser is Atelestus Pulicarius Fallen. 
Drapetis bygmza Roser is not assimilis Fallen, but is probably pusilla Loew. 
Tachydromia nigromaculata Roser becomes Drapetis (Elaphropeza) ephippiata Fallen. 
Tachypesa costalis Roser belongs to the genus Tachydromia (Tachista). 
Tachyfesa brevipennis Roser belongs to Tachydromia, and is the same as the later-described microptera Loew. 
Tachypeza obscura Roser is not W'inthemi Zetterstedt, but belongs to PlatyalPus, being synonymous with 
leucocheta Becker. 
Platypalpus ruficornis Roser is the same as (Aoracicus Lundbeck. 
Collin, in the Entomologists' Monthly Magazine, 1926-1927. is issuing a cursory review of British — 
Empididz, which contains many changes in nomenclature, largely the result of examinations of the type 3 
collections of Fallen, Meigen, Zetterstedt, Curtis, Walkerand Lundbeck. Collin's review is presumably 
not completed at the time the final proofs of this fascicle are being returned, so the student of this family 
is referred to forthcoming issues of the magazine for notes on the subfamilies Clinoceratinae and 
Hybotinze. A summary of Collin's findings so far as published is presented herewith : 
Platypalpus ambiguus Macquart, on which Bigot founded the genus Crossojalfus, is the same species as ^ 
Drapetis flexuosa Loew, instead of being Drajetis flavipes Macquart, as generally supposed. The 
subgenus Eudrafetis, Melander, therefore, falls into synonymy with CrossoPalPus as a subgenus 
- of Drafetis. 
Drafetis (Crossopalpus) curvibes Meigen is not assimilis Fallen, but includes aterrima Curtis, nigra Fallen and 
Zetterstedt, but not Meigen, moriella Zetterstedt, Picibes Zetterstedt and setigera Lundbeck, but — 
not Loew. E 
Drajetis (Crossopalbus) nigritella Zetterstedt is not aterríma Curtis, but includes aferrima Lundbeck and 
nervosa Loew. 
Drafetis (Crossopalbus) minima Meigen is a valid species, not the same as assimilis Fallen, but minima 
Zetterstedt is assimilis Fallen, as is also exilis Zetterstedt of the Insecta Lapponica. 
Drafetis exilis Meigen includes fusilla Loew and the female of migrifes Zetterstedt. 
Platypalpus minutus Meigen is the same as exiguus Meigen, but the exiguus of the British lists is miger 
Meigen. 
Platyfalpus fasciatss Lundbeck, not Meigen, is cursitans Fabricius, and cursitans Lundbeck is /aticinctus 
Walker. 
Platypalpus glaber Meigen is the same as /uteus Meigen. 
Platypalpus infuscatus Meigen becomes annulipes Meigen. 
Platypalpus ecalceatus Zetterstedt is a valid species, larger than calceatus Meigen. 
Bicellaria melena Haliday is synonymous with spuria Fallen, but sulcata Zetterstedt is distinct from spuria 
Fallen. 
CEdalea pallipes Zetterstedt is transferred to the genus T»richina. 
Euthyneura Myrtilli Macquart includes consobriua Zetterstedt and rostrata Zetterstedt, which were placed 
in Anthepiscopus, antea, p. 107. 
Microphorus crassibes Macquart is distinct from anomaius Meigen. 
Rhamphomyia sulcata Meigen, rugicollis Meigen, and fropinqua Meijere are the same. 
Empis barbata Macquart is a. Rhamphomyia, and is the same as bicolor Macquart 1823, not 1827, and 
pennata Macquart. 
Rhamphomyia plumifes Frey, Zetterstedt, Lundbeck, etc., is geniculata Meigen.
