Degeeria Meigen, System. Besch. Europ. Zwei. Insekten, Vol. VII, p. 249; 1838. 
Amedoria Brauer and Bergenstamm, Zweif. Kais. Mus. Wien, IV, p. 106; 1889, 
The synonymy of the first two is according to Schiner.' Brauer and 
Bergenstamm state’ that Desvoidy placed in Medina species belonging 
to Admontia and Degeeria, but they do not specify which of these spe- 
cies belong to Admontia. Since all of the recognized species placed in 
Medina by Desvoidy at the time of describing this genus belong to 
Degeeria, there would appear to be no doubt concerning the identity of 
these two genera. The identity of Amedoria with Degeeria has already 
been acknowledged by Brauer and Bergenstamm.* Our single species 
is black, with a brown tinge, the calypteres yellow, the wings strongly 
tinged with brown at the base and in front of the fifth vein; three post- 
sutural and three sternopleural macrochetie, discal macrochietie on the 
last three segments of the abdomen; length,9 mm. From the type 
specimen. Mount Washington, New Hampshire. (Journai N. Y. Ent.
