Coquillett, Type-species N. A. Diptera, 1910, p. 535, adopts the assertion of Hendel, 

 Verb. Zool.-Bot. Ges. Wien, 1908, p. 57, and includes as a synonym Iphis, Meigen, 

 Nouv. Class., 1800, p. 27. Aside from any other objections to the availability of this 

 name, it applies distinctly to species having an apical arista and hence can not be the 

 same as Doliehopus. In any event it would not disturb nomenclature here. 



While the present paper was in press, the writer received, on August 

 30, 1920, a new monograph of the Dolichopodidae of the pahiearctic 

 region (Europe, Siberia, etc.), by the well-known dipterist Mr. 

 Theodor Becker, of Liegnitz, Prussia. This is published in three 

 parts in the Nova Acta, Abhandlungen der Leopoldinisch-Caroli- 

 nischen Deutschen Akademie der Naturforscher, as follows: Band 

 102, No. 2, 1917; Band 103, No. 3, 1918; and Band 104, No. 2, 1918. 

 The genus Doliehopus is treated in the first part, pp. 120-180, and 

 127 species are recognized, of which 3 are placed in the subgenus 

 Ilydroceleuthus .
