According to collecting notes, females and immatures are most 
often collected while sweeping grass and shrubs. All stages and 
sexes were collected in woods, but more often in meadows or old 
fields. Males, apparently more prone to wandering, are collected in 
various kinds of pitfalls and traps. Mature males were collected 
primarily in May and June with fewer records in April and July. 
The earliest records are one in early February for Florida and two 
in March, one for Florida and one for Ohio. The latest records are 
in November for Florida and in September for New York. From 
the large collection of adult females, the distribution of collection 
records is as follows: March 5%, April 6%, May 19%, June 
33%, July 23%, August 10%, and September 4%. The latest is 
a single November record from Michigan. 
The construction of the nursery web, which is similar to that of 
Dolomedes, is given in detail by Bishop (1924) and will not be 
reviewed here. From personal observation and collection records, 
it seems that the nursery is almost always placed in high weeds or 
low shrubs in the ecotone between woods and adjoining field or 
meadow. Egg sacs appear in the collections primarily from the 
months of June and July, but appear as early as April and as late 
as September. 
Distribution. Eastern North America from Ontario and Quebec 
southward to central Florida and the Rio Grande Valley of Texas, 
and westward to Minnesota, Kansas, and Oklahoma. (Map 1). 
Material examined. Eighty-seven males, 208 females, 853 imma- 
tures. 
Discussion. The numerous names given for this species in the 
past can be attributed to the extreme variability in its color pattern. 
Some of these dorsal patterns are illustrated (Figs. 1-5) and can be 
placed into a continuum ; especially is this true for the abdomen. In 
the latter case, one can see a very distinct dark median band with 
lateral light areas ( Fig. 1 ) which, when followed through the series 
of drawings, appears to break down in distinctness while the undulat- 
ing white stripe breaks up into a series of white “dashes” (Fig. 3) 
and ultimately into a series of simple white dots (Fig. 4). The 
“subinflata” (Fig. 5) pattern perhaps indicates an extensive break-
