3. Zygoballus tibialis, sp.n. (Tab. XXVIII. figg. 3, 3a, 6, ¢ ; 4,4a-c, ¢ .) 
Type ¢, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 3, 2 4 millim. 
Hab. Guatemata (Sarg). 
The male can be at once recognized from other Central-American forms by the much 
enlarged tibial spur of the palpus. Legs ii., iii., and iv. are unicolorous yellow. In 
the female the legs are spotted with black at the apex of the segments, and the 
abdomen has a very striking dorsal pattern of white spots and bands. The latter sex 
can be known amongst closely allied forms by the shape of the vulva.

Hab. GuateMALa, Eastern district '. 
Very similar in general appearance to Z. tibialis and Z. maculatus, but recognizable 
by the form of the palpal organs and vulva, copies of the figures of which are here 
given from Peckham’s work. 
5. Zygoballus maculatus, sp.n. (Tab. XXVIII. figg. 7, 7 @, ¢.) 
Type, 2, in coll. Godman & Salvin. Total length 3°5 millim. 
Hab. Guatemaua (Sarg). 
‘This species is black, with a few white dorsal and marginal spots on the abdomen, 
and the legs i. brown, and ii., iii, and iv. yellow, annulated with black. It is 
probably recognizable by the form of the vulva only, for the coloration in these spiders 
is very variable, the general pattern being common to many of them. 
6. Zygoballus parvus.

Type B. magna, Peckham. Colombia. 
_ Very similar to Homalattoides in general characters, except that there is an entire 
absence of any coriaceous dorsal covering on the abdomen. ‘The mandible is toothed 
in the same manner as in that genus,
