gristigma n. sp. seen from below; b one of

Q very similar 
to I; the abdo- 
men a little dar- 
ker; ovipositor y- 
ellowish brown 
with long and po- 
inted cerci (fig. 3). 
This species is 
closely allied to 
D. magnicauda 
Lundstr. (Act.Soc. 
p. F.et F.Fennica, 
36, No. t,. p. 54 
fig. 56-58; 1912); 
but the distinct pterostigma immediately separates it from that 
species, and as shown in the figures the genitalia of the 
male and female differ from those of D. magnicauda Lundstr. 
The 21s of August I took 2 ¢ ¢ at 
Tvilum and Sminge near Silkeborg, and 
onthe 8t of September Mr.Esben-Petersen 
and I found the species very abundant at 
Funder near Silkeborg. 
Crypteria limnophiloides Bergr. Of this 
species I have taken 1 ¢ 1 Q at Silkeborg, 
24.9. and 20.10.18; the species is known 
from Finland and Northern Sweden. 
Adelphomyia senilis Hal. and Cladura 
fuscula Loew. In my list*) I have mentioned 
a new species Gonomyia furcata Kuntze 
in litt. The species- name was based on 
a series of 2 9d and 2 QQ. This autumn
