 This remarkable pioneer paper, which firmly established the basis of 

 classification of the smaller crane flies, records 46 species from the 

 District of Columbia, 42 of them being described as new. Of these 

 only 2 have since been found to be synonyms — namely, Geranomyicu 

 communis, which equals G. canadensis Westwood, and Limnobia de- 

 functa, which equals Dicranomyia simulans Walker.
