Besides Illyria, where it was discovered first, the typical species 
T. calceata Mik has been found in Westphalia (Westhoff) and in 
England (Verrall).

Of all the sections of Tipulina this is, next to the Limnobin«a 
anomala, the least homogeneous; it contains the largest number of 
forms doubtfully or artificially referred to it. But even the typical 
‚Eriopterina offer great difficulties in their generic distribution, owing 
to the importance of the structural peculiarities which distinguish 
many species. It is easy here to intruduce a large number of genera, 
but it is very difficult to distribute among them the new species dis- 
covered afterwards. The difficulty seems to be greater here than in 
any other group of Tipulidae. The genera Trimicra, Symplecta, 
Psiloconopa seem to pass into each other; the same is the case 
with Goniomyia and Gnophomyia. Some of the subgenera esta- 
blished by me, within the genus Zrioptera Meigen, seemed good 
enough for the north-american species, for which I introduced them; 
but they proved insufficient when new accessions in species had to 
be distributed among them. The study of freshly caught speceimens, 
but especially a larger material in species may perhaps gradually 
solve these difficulties. We must remember that exotic Eriopterina 
are almost unknown! Except the three species from Chili, published 
by Philippi, none whatever have been deseribed. But in the mean 
time we must be very cautions in establishing new genera of Erio- 
pterina. 
To the genera, artificially referred to the Eriopterina, I can 
add now, besides Oladura (N. America) and Sigmatomera (South 
and Central- America), two new ones: Lecteria (S. America) and 
Conosia (Asia). They have the appearance of Limnophilae rather 
than of Eriopterae. But they have no spurs at the end of the 
tibiae, which compels me to place them at the end of the Erio- 
pterina, until their true affinities are recognized. Except Sigma-

with „I believe now ete.‘‘ and ending, on the next page, with „typical 
Eriopterina.“ On p. 137, line 11 from top for Psiloconopa, read 
Goniomyia.
