The type specimen has been kindly submitted to me by M. E. Simon. 
Subfam. JISCHNOTHELINA. 
The two genera of this subfamily may be thus differentiated :— 
A. Base of mandible with two rows of stout teeth below, besides a short 
one of smaller teeth at the base. Coxa of pedipalp cuspulate at 
the base. Lateral anterior eyes slightly smaller than central 
anteriors. Central posterior eyes much smaller than central ante- 
riors, linear-oval, their longitudinal diameter less than the diameter 
of the latter. Tibia i. of the male produced into a spinigerous spur 
at the apex beneath. Protarsus i. produced into a spur towards the 
base beneath. Tibia and protarsus ii. normal, not developed. 
Terminal joint of the posterior spinners more segmentate, flexuose, 
and attenuate to the apex, larger than both the basal joints taken 
together. Anterior spinners wide apart at the base, separated by 
a distance equal to one and a half times the length of a single 
spinner. Labium not quadrately impressed behind the base, but . 
normally, biovately. Sternum scarcely longer than broad, circular. IscuNoTHELE, Auss. 
B. Base of mandible with one row of stout teeth only below on the inner 
margin of the fang-groove. Coxa of pedipalp not cuspulate at the 
base. Lateral anterior eyes much larger than the centrals, their 
diameter nearly equal to one and a half times that of the latter. 
Central posterior eyes distinctly larger than the central anteriors, 
quadrate-piriform. Tibia i. of male not bearing a spur beneath, but 
with numerous stout long spines; protarsus i. also with numerous 
stout spines beneath. Patella i. with several stout spines beneath. 
Tibia il. produced into a longer or shorter spinigerous spur beneath. 
Protarsus ii. produced into a low coniform spur at the centre 
beneath. Terminal joint of posterior spinners less flexuose, seg- 
mentate, and attenuate to the apex, as long as or scarcely longer 
than the second joint. Anterior spinners set closer together at the 
base, separated by a distance equal to, or less than, the length of a 
single spinner. Labium impressed broadly and quadrately at the 
base. Sternum much longer than broad, oval-elongate Evacrus, Auss.
