Description. See Kaston (1948). 
Range. Southern British Columbia to Labrador, south to Arizona 
and, in the east, to Texas and Florida. 
Florida Localities. Blountstown; Leon County; Gainesville; Enter- 
prise; Newman Lake; Clara; Ona. 
Comments. A study of Bryant’s type series of P. emertoni from 
New Bern, North Carolina, deposited in the Museum of Comparative 
Zoology, indicates that emertoni is identical with southeastern speci- 
mens of imbecillus. Gertsch’s (1934) synonymy of emertoni and 
mineri Gertsch is open to doubt, unless, of course, Gertsch considers 
mineri to be synonymous with i?nbecillus. P. mineri is a rare form 
known only from a male collected in the Michigan peninsula. It is 
very similar to imbecillus , but has the lateral apophysis of the palpal 
tibia longer and thinner, and the tibia itself more robust, than in most 
eastern specimens of that species. 
Within the rufus group, P. placidus, peninsulanus, marxi, and 
imbecillus together form a distinct series based on the relative length 
of the male embolus and the corresponding length of the copulatory 
ducts in females. In placidus and peninsulanus the embolus arises at 
between one-quarter and one-half the distance from the base of the 
tegulum, and the female duct is short, with its point of 1 communica- 
tion with the spermatheca visible from the ventral side. In marxi the 
embolus arises at the base of the tegulum, and the female duct is 
long and makes a convolution about the spermatheca. The embolus 
of imbecillus attains the greatest length found in any of the species 
of Philodromus ; it arises retrolaterally and nearly encircles the tegu- 
lum. The duct makes nearly two full turns around the spermatheca. 
In all of these forms a lobe arises at or near the point of communi- 
cation between copulatory duct and spermatheca, and the males are 
clothed dorsally, at least on the abdomen, w T ith shiny scales.

Description. Male: total length 2.80 mm; cephalothorax 1.33 mm 
long and 1.28 mm wide. These data are from Gertsch’s (1934) orig- 
inal description of P. mediocris. Carapace longer than wide, less 
convex over the top than in P. satullus Keyserling; lateral areas 
orange-brown; pale median area as wide as the posterior eye row, 
narrowed behind; a white V at the “cervical groove”; eyes ringed
