Ent. Tidskr., vol. 9, p. 127, 1888, preocc.) is conspecific with D. fipv- 
lipes as suggested by Edwards (Trans. Linn. Soc. Lond., vol. 15, 
pt. 2, p. 197, 1912). The material at hand indicates the possibility of 
a mistaken observation on Bergroth's part in regard to the position of 
Sc^, and it appears that Edwards is right in his assumption. It will 
require more material to decide this question finally.
