GENERA. 
A. Spines beneath tibie i. and ii. in pairs of 2—2—2—2, those beneath 
protarsi i. and ii. in pairs of 2—2—2, with or without lateral spines. 
(Small eyes situated nearer the posterior laterals. Mandibles 
often highly developed in the males, with 2—2 teeth in both 
sexes, set widely apart in the male. Cephalic region, in the 
male, with a tuft of hairs on each side about the middle, in 
a line with tke small eyes, convex in the middle in both 
sexes, viewed in profile. Clypeus not higher than, often less 
than, one-third of the diameter of an anterior central eye. 
Leg i. longest in the male; leg iii. longest in the female. 
Bulb of palpus not produced basally beyond the apex of the 
tibia. Spine of bulb apical, slender, and cirenlany curved, 
somewhat as in Sidusa.) 
B. Spines beneath tibiz i. and ii. in pairs of 2-22, those beneath 
protarsi i. and ii. in pairs of 2—2, with or without lateral spines. 
i. Mandibles in both sexes with from 2—5 or 6—5 teeth. Clypeus in 
male not less than a full diameter of an anterior central eye; in 
the female (Titanattus, 9 unknown) about half a diameter. 
a. Anterior row of eyes strongly recurved . an 
6. Anterior row of eyes only slightly recurved, by their posterior 
margins. (Small eyes nearer the anterior laterals. Cephalic 
area in the male with a tuft of hairs in front, behind and between 
the central and lateral anteriors ; the area itself is flat in both 
sexes, viewed in profile. Leg i. longest in the male, leg. 1. 
longest in the female. Bulb of palpus not produced basally 
beyond the apex of the tibia; palpal spine stout, springing 
from the inner side of the bulb and curving round towards the 
apex, with its point directed across the tarsus outwards.) 
ii. Mandibles in male and female with a single tooth on the lower 
margin and two teeth on the upper. Clypeus usually about one- 
third of the diameter of an anterior central eye, often much less. 
a. Tarsus of male palpus more elongate; bulb elongate, often 
attenuate and produced beyond the apex of the tibia. Palpal 
spine single, though sometimes bifid, springing either from the 
outer apical margin or from the apex of the bulb itself, not 
encircling the bulb in any way.
