companied by specific names or references to previous publications, 
but they are recognizably defined by being placed in a key. They 
appear in an acceptable publication and would seem certainly avail- 
able nomenclatorially as of this date. This paper was published 
twice, the first time above, and a year later, 1914b, where it is ac- 
companied in parallel columns by a German translation, a common 
custom at that time in this journal. I can find no changes whatever 
in the later edition. Between the appearances of these two “edi- 
tions”, the 1914a paper appeared. In lists of species all the re- 
maining 1909c names appear and are accompanied by valid specific 
names except Macrocormus while several of the names first pub- 
lished in 1913 are here accompanied by valid specific names for the 
first time. Macrocormus does not appear with a valid specific name 
in an acceptable publication until 1918, where it is listed as “T. 
(. Macrocormus ) ruhescens Bigot*’ and “Macrocormus sorhillans** . 
It is thus seen that if the names appearing in the 1909c and 1911a 
papers are not considered nomenclatorially available as of these 
dates, they became available in 1913 when they were defined, or in 
1912, 1914, or 1918 when they were accompanied by valid specific 
names. This change in dates appears to affect but two of these 
names, Dicladocera, which changes its sense as mentioned above 
and N eotahanus which becomes a homonym of N eotahanus Ricardo 
1911 (Rec. Ind. Mus. 4 ; 36 3, Type N. ceylonicus Ric. 1911). No 
new proposal of name for N eotahanus Lutz is necessary, since 
Taeniotahanus Krober 1930 (Dipt. Pat. S. Chile P. 140, Type T . 
occidentals Linn.) is already available. In any event the group is 
hardly of subgeneric rank and may eventually prove undefinable. 
The author has hitherto been inclined to take a liberal view of 
the case and accept the 1909 dating, though for the sake of fore- 
stalling possible future controversy, it might be well to adhere to a 
stricter interpretation of the rules and accept 1913 as the date for 
these names.
