SPECIES DESCRIPTIONS 
Before analyzing the individual species a few comments should be 
made concerning the treatment of certain sections. 
Structure. Under this heading follows a description of structural 
features not covered in the table of measurements and not defined 
specifically under generic characters. Tibial spination is relatively 
constant for each sex within a given species and there is a basic pattern 
throughout the genus. Therefore, two tables are constructed showing 
the typical patterns of tibial spination in S. calif ornicus and subsequent 
species are compared to these. 
When the difference between two dimensions is less than 0.05 mm 
these dimensions are considered subequal. 
Color. Color descriptions are based on specimens submerged in 
alcohol and viewed at low power ( 10 X ) under a dissecting scope with 
illumination from a microscope lamp. In fresh alcoholic specimens the 
color is much the same as in the living spiders. The contrasting light 
and dark markings, particularly on the carapace and dorsum of the 
abdomen, are created by light and dark hairs. When these hairs 
become rubbed off, the underlying color of the integument no longer 
provides such marked contrast. All of the figures and descriptions are 
based on specimens with the hairs present. In some cases, of course, 
this is very difficult because of damage to the specimen. 
Records. Locality records for states are listed geographically, coun- 
ties alphabetically under states, cities and towns alphabetically under 
counties. The records are for specimens examined except where noted. 
The lower case “o” is used to indicate a juvenile specimen in the same 
manner that the normal cf and ? signs represent a mature specimen. 
The 00, cf cf and signs indicate more than one specimen collected 
at a single locality.
