Notes concerning the synonomy of Danish Tipulidae. 
By 
Peder Nielsen, Silkeborg. 
In the list of Danish Tipulidae, published by S tæger in 
Krøyer’s: „Naturhistorisk Tidsskrift“, Bd. 3, 1840, several spec¬ 
ies are described as new to science. Later on most of these species 
have been misinterpreted by the scientists, and what moreover has 
caused confusion is, that some of them are described as nov. sp. in 
Zetterstedt’s valuable work “Diptera Scandinaviae”. 
By kindly permission of W. Lundbeck, curator of the Ento- 
mological department at the Zoological Museum of Gopenhagen, I 
have had the pleasure to examine the Tipulidae in the collection 
of Stæger, and below I give the result of my examination. 
Dicranomyia ( Glochina ) 
fvontalis Stæg., Krøyer’s 
Naturhist. Tidsskr. III, p. 
52, 1840. 
A male of this species 
is present. The discal cell 
is open, and the species 
proves to be the same as 
D. osien-sackeni Westhoff 
(Uber d. Bau d. Hypopyg. 
d. Gatt. Tipula, p. 57, 1882). 
I have compared the spec¬ 
ies with a specimen of 
osten-sackeni , kindly sent 
me by Prof. J. C. H. de 
Meijere. The name fron¬ 
talis has the priority.
