recurved. In I. varius, L. Kocli, the fovea is straiglit, as is tlie case with 

 the form described lierennder ; /. (h'sfiiictas, on the other Iiaud, has tlie 

 fovea slightly procurved. If the shape and direction of the thoracic fovea 

 is of strict generic importance, then 1. hroomi and 1. dint in etas will 

 ultimately have to be accommodated in other genera, though for the 

 present it may be as well to let them remain where they have been 

 placed.

 hairs. Eyes. — Distributed over two rows of four each, the front row 

 being procurved, and the rear recurved ; front lateral eyes largest of the 

 group, elliptical, and poised obliquely ; front medians round, very slightly 

 smaller than the long diameter of the rear lateral eyes, separated from 

 each other by about once their own individual diameter, and each again 

 from its lateral neighbour by rather less than that space ; rear side eyes 

 elliptical, poised obliquely ; posterior intermediates smallest of the group, 

 but not minute, oval, each just touching the ring of its outer neigh- 

 bour (PI. xxiv., fig. 117). Legs. — Moderately long, not strong, yellow,

 bespined ; tarsi i. and ii. only scopulated ; relative lengths : 4, 1, 2, 3. 

 Palpi. — Rather long, moderately strong, similar in colour, clothing and 

 armature to legs ; tarsi scopulated. Falces. — Concolorous with cephalo- 

 thorax, projecting, modei-ately strong, clothed with fine hairs and coai'se 

 bristles ; inner ridge of each falx armed with a row of six moderately 

 strong teeth ; f<<ng shining, reddish-brown. Maxillce. — Yellow, hair}-,
