The present insect is very locally distributed in marshland. At 

 Fredericksburg it was found in high wet grasses in an upland depres- 

 sion. The species has been recorded from Long Island, New York, 

 and Point Pelee, Ontario, south to the Argentine Republic.

We have examined, in the Scudder Collection, two males and three 

 females of the original series of two males and four females on which 

 Scudder founded his Mermiria vigilans. In consequence we can 

 fully endorse Morse's synonymy of vigilans under the present species. 40 

 At a later date we will speak in more detail of the variability of this 

 interesting dry-land form. 



The known distribution of alacris in the eastern States extends 

 from east-central and central (Salisbury, on the basis of immature 

 individuals not seen by us) North Carolina and northern Georgia 

 (Toccoa), south to central Florida (Cedar Keys, Sanford and Titus- 

 ville).
