Studies on Tipulidae II. 219 
Strobl, XIV, Progr. des k. k. Obergymn. in Seitenstetten 1880 (preocc. 
Neuropt., Dipt.), and Diazoma Wallengren, Entom. Tidskrift, Stockh. 
1881, p. 180 (preocc. Lamark, Mollusca 1816). The true characters 
of the new genus being as yet doubtful, I abstain from inventing a 
new name for it. 
Section V. Anisomerina. 
To the general remarks about this section in Monogr. ete. IV, 
p. 238—239 I have nothing to add. About the genus Bertea Rond. 
(ibid.) I am not better informed than I was before, 
Anisomera.

Ex parte: Peronecera Curtis, Brit. Entom. 539; 1836. 
I do not think that the genus Peronecera Curtis, based merely 
on the number of joints of the antennae, should be maintained, the 
more so as the number of these joints differs very little from that 
in Anisomera, and, moreover, as it does not seem to be constant. 
Anisomera, male, has six joints, but sometimes seven (I counted 
distincetly seven joints on fresh specimens caught by me; the last 
of them was very short). Peronecera male has seven joints. I do 
not know whether female specimens of Anisomera sometimes have 
seven joints, nor do I find any positive statement about it; in such 
specimens the joints are diffieult to count, as the last of them shows 
several indistinet subdivisions (comp. Mon. ete. IV, p. 240, footnote). 
Peronecera Q@ is said to have eight joints by Curtis, nine by 
Loew. A female Peronecera from Portugal, which I have before 
me, shows distinetly eight joints. This specimen (colleeted by Mr. 
Eaton June 1880) is larger than P. fuscipennis Curtis, the first 
submarginal cell is longer, the great crossvein is a little distad of 
the proximal end of the second posterior cell. It is probably a new 
species.
