1. Aysha simplex. 
Aysha simplex, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 227, t. 29. figg. 4, 4a-f(¢), 
5,5a(@)'. 
Type ¢, cotype 2, in coll. Godman & Salvin. Total length, ¢ 9, @ 125 millim. 
Hab. Panama, Veraguas (Boucard '). 
2. Aysha minuta, sp. n. (Tab. VII. figg. 18, ¢; 19,2.) 
Type, d, in coll. Godman & Salvin: Total length, ¢ 6, Q 7 millim. 
3 9. Entirely dull yellow-white. General structure as in other members of the genus. 
3. Palpus: tibia, including the spur, longer than the tarsus; tibial spur, upper branch, long, sinuous, stout, 
curving downwards and outwards at the apex. Near the base of the upper spur there is a smaller spur 
on the outer side of the segment. The bulb is short and broad, terminating at its apex in a long spiraloid 
spine. The tarsus is short and gibbous in the dorsal region. 
Q. Vulva very simple, consisting of an oval space enclosed within a dark brown chitinous margin, open in 
front and behind. In the anterior middle of the area is a minute orifice. 
Hab, GuateMaLa (Sarq). 
The form of the vulva of this species is exceedingly similar to that of A. simplea, 
but the larger size of the latter will be noticeable.

Type, 2, in coll. Godman & Salvin. Total length 6-5 millim. 
Colour entirely dull yellow-white. Structure as in others of the genus, Vulva with a broad semicircular 
valve-like chitinous plate at its anterior margin, open behind, covering a small cavity. 
Hab. Panama, Bugaba (Champion).
