AGELENOPSIS. 
conspicuous spiraliform process. Bulb not bifid at the base on the 
inner side. 
a’. Palpal bulb very complex, with a conspicuons, transverse, chitinous 
piece at the base, its inner anterior margin bearing two short 
adjacent spurs, besides other convoluted and pointed processes 
6°. Palpal bulb quite simple, without any transverse piece at the base, 
and without convoluted and pointed processes. . . . . . 
Females. 
A. Femora, and often the tibiz also, annulated with dusky brown or black. 
a. Carapace with a more or less distinct, broad, central, longitudinal, pale 
band, and broad marginal bands. Vulval area without any large, 
circular, central cavity. 
a‘. Vulval area divided for two-thirds of its length by a broad central 
channel formed by a pair of chitinous lateral lobes. 
a’. Posterior margins of the lateral lobes uniformly rounded and 
blending with the posterior margin of the vulval area . . . 
6°. Posterior margins of the lateral lobes terminating in a sharp 
point on each side, and extending beyond the posterior margin 
of the vulval area, with also a second blunt cusp farther along 
their margin. . . 2... 2. ee : 
6'. Vulval area not divided by a broad central channel. 
a’. Vulval area having towards its anterior margin a pair of large, 
deep, reniform cavities, separated in the middle by a broad 
chitinous septum, which expands posteriorly and laterally to 
form the margins of the cavities . . . . 
b°. Vulval area without large cavities towards the anterior margin. 
a‘. Vulval area with a large, deep, oval-rectangular cavity on the 
posterior margin, with anteriorly a narrow central septum 
6‘. Vulval area with a small transverse-oval cavity on the posterior 
margin; the anterior margin of the latter bearing a pair of 
small, sharp, convergent cusps. 
a’, Transverse-oval cavity broader, filled in with a central, 
transverse, convex piece. . - eo ee

Norr.—The form of the vulva in the genera Agelena and Agelenopsis being exceedingly variable, it is very 
difficult to be certain as to the specific distinctness of some of the allied forms.
