ZYGOBALLUS. 291 
2. Vulval area longer than broad. (Vulva consisting of a pair of small 
orifices two and a half diameters apart and two diameters from the 
posterior margin, which is emarginate in the middle.) . . . . . . maculatus, sp. un. 
Nore.—The coloration in the last three species is much the same. Legs i. brown, protarsus and tarsus paler ; 
ii., iii, and iv. yellow, each segment tipped with black or brown at the apex ; femur iv. with a larger spot of 
black at the apex on the inner, or upper, side. Abdomen brown or black, with spotted and streaked white 
pattern, which is very variable. In the only example we have of Z. maculatus the white pattern is almost 
obsolete, leaving three white marginal dorsal spots and four very indistinct central spots. If it were not 
for the difference in the position of the vulval orifices, I should not hesitate to regard both 4. maculatus and 
Z. tibialis as identical with Z. minutus, Peckh. 
Z. parvus, Hentz, is unknown to me and cannot therefore be included in the Table.

The non-incrassation of tibia i. in both sexes and other characters given in the Table 
will serve to distinguish this species from other Central-American forms known to me. 
I have not seen Peckham’s type of Z. strenuus, but there can be little doubt as to its 
identity with the female of R. munda. The present species much resembles Z. suavis, 
Peckh., from Jamaica, especially in the armature of the mandibles (sec. Peckham’s 
figure); but the tibial spur is much longer and the legs ii., ili., and iv. (instead of 
being brown) are yellow, with black slashes along the sides. 2. munda is also identical 
with Z. rufipes, Peckh. (cf. the figures of the male). 
2. Zygoballus remotus, (Tab. XXVIII. fig. 2, ¢.) 
Zygoballus remotus, Peckh. Occas. Papers Nat. Hist. Soc. Wisc. ii. 1, p. 89, t. 7. figg. 2,2a (2g) 
(April 1896) *. 
Type, d, in coll. Peckham. Total length 4:3 millim. 
Hab. GuateMa.a}!. 
Peckham ! makes no mention of any tooth, spur, or cusp on the basal segment of 
the mandible above, at the apex, so that one must conclude there is none present ; and 
the absence of this will enable Z. remotus to be distinguished at once from the male 
of Z. rufipes. The legs ii. iii., and iv. in the present species, too, are unicolorous 
yellow (not slashed with black, as in Z. rufipes). Our figure of the palpus is taken 
from Peckham’s work.
