not at all. Mandibles black, clothed with hoary-white hairs in 
front. 
Structure. General characters similar to those of other species of 
the genus. Central posterior eyes one diameter apart (less in ¢ ); 
clypeus six times as high as the diameter of an anterior central 
eye (in ¢ four times). 
Vulval area broader than long, rounded, rectangular ; central 
tongue distally broad, widely dilate basally; variable in different 
examples. 
Palpus. Tarsus twice as long as broad; tibia two-thirds the 
length of the tarsus; one-fourth longer than the patella, Tibial 
spur broad basally, curved apically, terminating in a small hook, 
having on the inner side a slightly serrated ridge. The embolus 
of the bulb has a stout erect spur springing from the cavity below 
the apex of the lamina of the bulb, while the embolus itself is 
short, strongly curved, and conspicuously flanged on each side. 
Hab. Couompra, dried examples (¢ & 2); Venuzuena, dried 
examples (¢ & @); also many examples in spirit, in coll. Brit. 
Mus.

Ann. Soc. Ent. Belg. xlii. p. 20 (1898). 
Type ¢, gynetype Q, in coll. E.Simon. Total length (3, 2) 
90-25 mm—(d¢). Carap. 11. leg i. 745 i. 82; m1. 62; iv, 
85 mm. Tib.i. & iv. 19°5 mm. Prot. iv. 22 mm. 
Both sexes with 4 teeth on the lower margin of the fang- 
groove. Legs 4, 2, 1, 3. Clypeus 3-3} times in height the 
diameter of an anterior central eye. 
Carapace, abdomen, and legs entirely without dark bands or 
annules, or these are at least very faint; entirely clothed with 
dusty olive-brown hairs and pubescence. 
Palpus. Tibia 14 times longer than broad ; tibial spur slender, 
its apex bent over, forming a single small hook. The inner 
apophysis deeply impressed across the middle, forming two blunt 
cusps. 
Vulva with a short broad central tongue, broadly dilate basally. 
Tf I am correct in my identification of Simon’s species, it is a 
common Spider throughout Ecuador.

Clypeus 4 times the height of the diameter of an anterior central 
eye. The whole of the central area of the carapace black, with
