~ 1. Tibial spur very broad at its apex, viewed in profile. Tibia of palpus not 
longer than broad, patella broader than long, viewed from beneath. 
Spine at the apex of the bulb longer and much stouter. (Tibia i. 
incrassate, scarcely three times longer than its diameter.) Abdomen 
black, with three white spots on the dorsal margin on each side. Legs.

2. Tibial spur short, but sharp, its apex directed forward. Tibia of palpos 
twice longer than broad ; spine at the apex of the bulb shorter and quite 
slender. Abdomen dark brown, with a white anterior marginal band 
and two faint white transverse dorsal bands, becoming obsolescent in the 
middle. Palpi and leg i. red-brown, protarsus and tarsus paler; legs i1.,

trochanters and the base of the femora ili. and iv. yellow. Carapace 
dark brown, with a white band round the lower margin and some other 
patches of white hairs. (These characters are all deduced from Peckham’s 
description and figures.) 2. 2. 2. 1. 1 6 6 ee ee ee ee minutus, Peckh.
