Family CECIDOMYIIDAE. 



It should be remarked respecting the nomenclature of this 

 family that the alterations suggested by Dr. Karsch, and accepted 

 by Riibsaamen, Keififer and others, have been vigorously opposed 

 by both Aldrich and Osten Sacken. Aldrich says (Cat. N. Amer. 

 Dipt., 152): "The practical effect of the changes adopted by 

 Karsch, Riibsaamen and Kieft'er is to apply the name Cecidomyia 

 to the Di ptosis of Osten vSacken's catalogue, and to divide up his 

 Cecidomyia between Rhahdophaga a.\\A Dasynenra the adop- 

 tion of the changed nomenclature will leave few members of the 

 family in the same genera to which Osten Sacken referred them." 



Osten Sacken had expounded and, I think, fully substan- 

 tiated his views (Ent. Month. Mag., 1901, p. 40) and concluded 

 as follows : " What I would propose now would be to restore as 

 far as possible the original concept of Cecidomyia of Meigen and 

 Latreille, and to consider the very numerous new genera, since 

 formed at its expense, as subgenera." 



My own view is identical, but having no practical experience 

 of the family I refrain from inaugurating the change in the pre- 

 sent catalogue. 



It must also be noted that species of which the adult form is 

 not known are not included as an integral part of the catalogue, 

 but the names of such species are given, with a brief reference to 

 the works in which they are described.
