Urophora intcmif'fa Macquait is a synonym of Rivellia hoscii, and 

 Orlalis bipars Walker, of Rivellia viridulans. Loew was correct in 

 placing Ortalis ofrccda Walker as a synonym of the last named species, 

 with which the description fully agrees, while it does not at all agree 

 with Cluvlopsis cenea, to which Osten Sacken assigned it from an ex- 

 amination of the supposed types. 



Tcphroiiota hiniiilis Loew is a synonym of Trypeta narytia \\'alker. 

 The fact that Walker attached the label to a specimen of Clurfopsis 

 (Enca, as observed by Osten Sacken, is sim])ly another instance of that 

 author's well-known carelessness; his description oi iia>ytia agrees per- 

 fectly with liii/iiilis, while it is not at all applicable to icfiea. 



Our s[)ecies of Ccfoxys should be placed under Melieria of Des- 

 voidy (Essai Myod., p. 715; 1830). The name of Ccfoxys, which 

 dates from the year 1835, could be used for the European species 

 placed by Schiner under Mrckclia, the latter name being preoccupied. 

 Maccpiart originally proposed the name Ccroxys to include the two 

 genera Melieria and Afeekelia of Desxoidy.
