numbers in the tangled herbage of the slopes adjoining the 

 marsh ; Delanco, August 26th, where 1 captured a single female 

 along the margin of the tidal flats of Rancocas Creek about a 

 mile above the railroad bridge ; and Rougher, one mile south 

 of the village of Rancocas where on September 8th I found it 

 unusually frequent along the edge of the tidal flats of Rancocas 

 Creek, a few rods below the draw-bridge. At this latter point 

 I took within less than an hour 8 males and 10 females. 



While locally rather frequent, attcnuatits impressed me as 

 very erratic as regards numbers and distribution. The type of 

 habitat in which it was invariably found is verv wide-spread 

 in fact, almost the only type of marsh represented in the 

 district under consideration. Nevertheless, in many localities 

 where conditions were in apparently every particular favorable, 

 diligent search often failed to reveal any individuals of the 

 species. On the day when I took the single female near Delanco 

 I examined the borders of the Rancocas tidal flats for a distance 

 of fully I /R mile without finding another individual. At Tur- 

 lington, although it was rather frequent below the bridge prev- 

 iously mentioned, I was unable to find any above it, although 

 in this portion conditions in the marsh were apparently identical 

 with those below the bridge. 



With the exception of a few individuals observed at I'.ur- 

 lington in the fringe of tall grasses (Panicnni ? '/>//<// ;;M and 

 tangled shrubbery which occupied the low slopes bordering 

 the marsh, all examples of attcnitatiis observed by me in Xew 

 Jersey were found exclusively in marshes formed by the tidal 

 flats which in this section border all those streams whose flow 

 is affected by the tide. As previously mentioned, the va-tly 

 greater part of these flats is covered with a high. dense stand 

 of wild rice ('/. \zanui palnstris L. ) , which along their landward 

 margin^ intermingles \vith and is partly replaced by a \ariet 

 of marsh-dwelling plants, the more prominent of which have 

 already been noted. Owing to the sofl and treacherous nature 

 of the ground in these marshes, observations were necessarily 

 largely limited to the marginal portions where the mixed vege- 

 tation prevails, and it was therefore in this vegetation that the 

 greater number of individuals of atli'nmiliis were taken, but
