long black hairs, cavity extends length of the cymbium and 
filled with the palpal organ, bulb divided longitudinally, 
larger half shows duct of two loops in upper portion, smaller 
half with the rather short, straight embolus that starts at 
distal end with a short tooth near origin and tip near the 
end of cavity. 
Female. Length, 4.9 mm., ceph. 2.0 mm., abd. 3.0 mm. 
Cephalothorax dark brown, eye area black with a sparse 
covering of short white hairs, no median white spot as in the 
male but the same fringe of long black hairs above a.m.e., 
thoracic groove wanting ; eyes, anterior row not as strongly 
recurved as in the male; mandibles, superior margin with 
five teeth, no oblique row of bristles on inferior margin as 
in the male; abdomen black with white and faun-colored 
hairs forming a pair of large white spots about the middle,

This species is found throughout Europe and according 
to modern authors, it is subject to variations in color pat- 
tern and shape of the tibial apophysis of the male palpus and 
even the longitudinal division in the palpal organ. The 
museum collection has a male from the Paris Museum and a 
pair from the Peckham Collection, probably received from 
Simon. The male from the Paris Museum has the same 
large spoon-shaped tibial apophysis, the palpal organ with 
the longitudinal division but the embolus is half hidden, so 
that it is impossible to see if it has a tooth near its origin. 
The superior margin of the fang groove has three unequal 
teeth as figured by Simon in the Histoire Naturelle des 
Araignees, 2 :578, fig. 699; figure 700 on the same page 
shows the large spoon shaped tibial apophysis but the am- 
bolus is a long slender tube, starting on the margin about the 
middle on the same side as the apophysis, (retrolateral) , 
something that is not mentioned in any description of the 
species. According to Simon and Reimoser, it has received 
several names, which is not surprising from the variations
