Small eyes nearer the anterior laterals. Tibia i. with 2—2--2--2 spines beneath and 1—1 laterals on the 
inner side. Protarsus i. with 2—2 spines beneath ; protarsi iii, and iv. with two spines at the apex and 
one only on the outer side towards the base. Tarsi of legs i. and ii. fusiform. Femora i. and ii. with 
the usual group of three spines at their apex in front. Sternum twice longer than broad, very narrow 
between the anterior coxa, which are almost in contact. Coxa i. shorter than iv. Mandibles with one 
tooth above, two below. Posterior spinners more slender than the anteriors and distinctly longer; 
centrals slightly shorter than the anteriors.

Type J. muscosa (Clerck). Europe. 
Q. Tibia i. with 2—2— 2 spines, the first pair sub-basal, and one lateral on each side (in some species on 
the inner side only); protarsi i. and ii. with 2—2 spines beneath. Femora with two long spines above 
and three shorter ones near the apex, but not closely grouped. Patelle without spines. Tibia iii. without 
any spines above, two at the apex beneath, and 1—1 laterals; tibia iv. with 1—1 beneath ; protarsi iii. 
and iv. with 1—1 beneath and four at the apex. Coxa i. slightly shorter than coxa iv. Sternum 
twice longer than broad, dilated bebind and very narrow between coxe i. Small eyes midway between 
the laterals. Ocular quadrangle broader than long, as wide in front as behind. Carapace with a 
depression behind the cephalic area, where the central stria is situated, elongate, more or less compressed. 
Abdomen very elongate, more or less parallel-sided, and compressed. 
The species here referred to this genus differ somewhat from the typical form 
(IZ. muscosa), chiefly in having more slender anterior legs and only three (instead of 
four) spines on the outer side of tibia i. It is quite possible that I. melanognatha 
will eventually be referred to another genus. I take WM. muscosa as the type, because
