PARASYNEMA, gen. nov. 
Type P. cirripes (O. P.-Cambr.). Mexico and Guatemala. 
Eyes as in Xysticus; central quadrangle broader than long, not narrower in front. Posterior row recurved ; 
eyes equidistant, or centrals further apart and smaller than the laterals. Anterior row recurved ; centrals 
much smaller than the laterals and much further from each other than from the laterals. Clypeus equal 
to more than four diameters of an anterior central eye. Femora i. with a few fine long bristles, none on 
ii. ; tibiee i. and ii. with 2—2 long bristles and two short apical spines. Protarsusi. with 2—2—2—2—2 
short, stout spines beneath ; no lateral spines; protarsus ii. with 2—2—2—2 spines beneath. The body 
and legs of the male are much more densely clothed with stout bristles than in the same sex of Xysticus 
. Parasynema cirripes. (Tab. X. fig. 23, 9.)

TMARUS. 
Tmarus, E. Simon, Araign. Fr. ii. p. 259 (1875). 
Type 7. piger (Walck.). Europe. 
Mandibles plain, without teeth. Labium nearly three times longer than broad. Anterior row of eyes straight by 
the centre of the laterals and the posterior margin of the centrals; eyes equidistant, laterals much larger. 
Posterior row slightly recurved ; centrals one-fourth closer together than to the laterals. Lateral posteriors 
distinctly larger than the centrals. Clypeus as high as the length of the central quadrangle and very 
prominent. 
Lateral eyes on two distinct tubercles, the posterior tubercles being the largest. Carapace straight above, 
abruptly inclined behind. Central quadrangle square (or broader than long), but narrower in front. Legs 
spinose ; i. and il. equal in length. Tibice i. and ii. with 2—2 spines at apex beneath; protarsi i, and ii. 
with 2—2—-2—-2 spines beneath, as well as lateral spines. Tarsi with a long narrow smooth central 
area beneath flanked by a row of setz on each side. Tarsal claws toothed throughout. 
These characters are drawn from the adult female of the European 7. piger (Tab. X. 
fig. 24).
