of five spines (the basal ones much longer) on the inner side. Femora i. and ii. with a series of 8-10 
(variable in number in different species) long spines beneath, iii. with one or none, iv. with a series of 
five or six beneath. Patella of pedipalp with a single apical spine. Tarsal sheath with a well-developed 
uncus at its base. Lateral eye-groups not prominent ; situated well behind the anterior margin of the 
base of the mandible. Central quadrangle not prominent, but the posterior eyes are set upon two 
prominent tubercles, two diameters apart and slightly larger than the anterior centrals (much less disparity 
than in the female sex). Anterior row straight, central and lateral eyes being equidistant from the 
margin of the clypeus. Quadrangle square, not narrower behind. Coxe iii. and iv. and trochanter iv. 
with one or more stout spines *. Abdomen with two low tubercles between the anterior shoulder-angles. 
Q. Central quadrangle of eyes wider behind, broader than long; posterior centrals much larger, two full diameters 
apart, set on two rounded tubercles, almost overhanging the anterior eyes. Laterals in contact. Anterior 
row straight, measuring from the margin of the clypeus, appearing slightly procurved ; posterior row 
slightly recurved ; the laterals separated from the central posteriors by a space one-fourth wider than 
that occupied by the latter. Femora i—iv. devoid of spines beneath. ‘Tibie and protarsi i., i1., and iii. 
with a double row of spines beneath, iv. with a single row. Abdomen with two (or one) tubercles 
between the anterior shoulder-angles. Scapus and base of vulva fused together, the apex of the scapus 
prolonged into a small, thin, rounded, or pointed, spoon-like plate.

It is probable that McCook has made a slip of the pen (coxa ii. for coxa iii.) in his statement that the 
male of Wiwxia ectypa (Walck.) has a dentiform spine on coxa ii.
