The chief difference between the classification of Johann- 
sen and that of Edwards will be noted in the limits of the 
two subfamilies Sciophilinae and Mycetophilinae. Johannsen, 
1911, recognized that there were two quite distinct groups in 
the Mycetophilinae and gave a classification of these two 
series based on the arrangement of setulae on the wing. 
Edwards, 1924, become convinced that a more natural 
grouping would be obtained by placing the genera included 
in Series I of the Mycetophilinae of Johannsen in the Scio- 
philinae. 
Since some of the genera have been split or united with 
other genera since the date of Johannsen’s work, I believe it 
best to mention the more important changes that have oc- 
curred. 
1. The genus Hesperinus was removed by Johannsen to 
the Bibionidae. 
2. Pachyneura is now placed in a separate family re- 
lated to the Anisopodidae. 
3. Mycetobia is placed with the Anisopodidae by some 
authors or in a distinct family the Mycetobiidae. 
4. Palaeoplatyura is placed with the Ceroplatinae by 
Edwards. 
5. Cerotelion is considered to be a subgenus of Cero- 
platus. 
6. Diomonus is united with the genus Leptomorphus.
