namo Camilla, applied by Ilaliday to the genus including Drosophila glahra 
(Fall.), had been previously employed, Rondani’s name Noterophila must be 
adopted for it. Loew states that he possesses what appear to bo three other 
species of this genus, one of which he describes. 
Schiner replies to Loew’s criticisms on his treatment of the species of 
Opomyza and Geomyza. Berl. ent. Zeitschr. 1865, p. 125. Loew maintains 
his previous statements. Ibid. p. 356. 
Geomyza. Loew (Berl. ent. Zeitschr. 1866) discusses the characters of 
this genus as compared with those of Diastata, Balioptera, Opomyza, and 
Anthomyza. The differential characters of the first and last of these genera 
are shown, in parallel columns, 1. c. pp. 16-16. The number of European 
species recognized by Loew is seven. 
Opomyza Jlorum (Fab.) is described by Taschenberg (Natttrg. wirbell. 
Thieve, pp. 242-243) as feeding upon rye. It is also figured, pi. 7. fig. 10. 
Opomyza. Loew (7 c.) indicates the distinctive characters of this genus 
and Balioptera {1. c. pp. 26-27) and describes five European species. 
llhkno'essa (Loew). Loew characterizes this genus afresh (1. c. pp. 34- 
35) and describes four European species, namely R. cinerea (Loew), R. 
(^Opomyza) cimrella (Halid.), and two new species.
