I suppose, has had the true senilis of Haliday, and he 
has not seen Cladura fuscula Loew. 
Cladura fuscula Loew is a very tiny species; the wings 
are hyaline, somewhat pilose and narrower than the wings 
of A. senilis; nor the legs are so robust and there is no 
spurs on tibia. | 
In the description of Cl. fuscula Loew (I. c. p. 66 Anm. 
3) writes: „Da die Hinterrandszelle- bei Cladura fuscula 
zuweilen ganz ausserordentlich klein ist, so ist es nicht un- 
möglich, dass vielleicht einzelne Exemplaren vorkommen 
denen sie ganz fehlt.“ Amongst my material I have ob- 
served 1 4 and 1 Q without forked M,. 
I have found Cl. fuscula Loew at Ry, Silkeborg and 
Funder in August — September. 
A. senilis Hal. is a somewhat more robust species, the 
wings broad, pilose, pale brownish tinged; the hind and 
the intermediate tibia with distinct spurs. 
As to the question, whether CZ. fuscula is a Cladura 
in Osten Sacken’s sense or not, I cannot at this time say 
anything, because I have not seen an American Cladura. 
Probably a new genus may be erected for this species. | 
suppose the synonymy of the two species may be the 
following:

October the 20" Mr. Esben-Petersen and I found 
this species in both sexes (Kejlstrup at Silkeborg), and
