To Lord Walsing-ham is due the credit for the entire synonymy. I 

 am indebted to him for his manuscript note that mediofuaceUa should 

 ])(» added to the already published synonymy, which the description also 

 b(>ars out. 



It is a common species in the District of Columbia, which I have 

 taken in numbers in very early sprino- (March, April), and again in 

 July. 



Its life history is unknown as yet, but a clew may be found in a 

 specimen which issued, April 25, from old, dr}^ cornstalks collected 

 and placed in breeding case the previous fall. This specimen was per- 

 fect and seemingl}^ fresh, but not having observed the larva, 1 am 

 unable to say with certainty that it was not an overwintering moth or 

 that the larva accidentally had found a convenient pupating place in 

 the cornstalks.

Through the kindness of Dr. Dietz 1 have examined his t3'pes of 

 this species and the National Museum possesses several cotypes. It 

 is a typical Gelechkc, which was placed b}^ error in an unpu])lished 

 manuscript genus of Lord Walsinghanrs, thereby spoiling the name 

 IWudoeJielaria for future application to the intended — to me 

 unknown — genus.
