 abundant in 1913 than in the last few years, but does not

 the 18th, and is present in about half the hauls taken from 

 that date to July 11th, after which it is absent (except for 

 one haul containing four specimens on November 7th) to 

 the end of the year. The largest hauls are 1,500 on 

 May 9th, and 440 on June 24th.
