OXYOPES. 
Oxyopes, Latreille, Nouv. Dict. d’Hist. Nat. xxiv. p- 1385 (1804). 
Type O. heterophthalmus (Latreille), Europe. 
The spiders of this genus differ from those of Hamataliva and Oxyopeidon in having 
the eyes of the posterior row equidistant, or nearly so; and from Pewcetia in the strong 
procurvature of the posterior row of eyes, and in the males being without a “ clavis” on 
the palpal bulb. There are not more than ten species described from the Neotropical 
region, three only of these being from Mexico or Central America. 
Those known to me may be recognized as follows :— 
Males. 
A. Tarsus of palpus produced at the base on the outer side into a more or less 
conspicuous conical prominence. . 
1. Conical prominence more conspicuous. Bulb of palpus with a pair of 
short, closely adjacent, hooked spines at the apex, plain, without any 
separate elongate processes. Tarsus of palpus deeply concave beneath, 
with the external side produced to form a blunt angle. Patella with a 
brush of stiff hairs along the anterior margin beneath . 
2. Conical prominence less conspicuous. Bulb of palpus without hooked 
spines at the apex, but with two elongate processes. Tarsus of palpus 
not concave beneath. Patella without any fringe of stiff bristles . 
B. Tarsus of palpus not produced into a decided conical prominence at the 
base on the outer side. 
i. Lower spur on tibia of palpus divided into two or three distinct cusps. 
a. Lower spur of tibia divided into three cusps. 
1. Lower spur of tibia much longer and more developed. Central por- 
tion of bulb broad, long, and flat, terminating basally in a short 
hook, its apex directed inward (see figure) . . 
2. Lower spur of tibia much shorter and less developed. Central 
portion of bulb narrower and shorter, curving across the bulb, 
concave and squarely truncate at the apex (see figure) . . . 
6. Lower spur of tibia divided into two cusps. 
a', Anterior branch of lower spur larger, broader, and more spatuliform. 
Carapace yellow, with a pair of fine black lines down the clypeus 
and mandibles infront. Sternum yellow. Abdomen olive-brown, 
with a pale, central, dorsal band . . . ... ee 
b!, Anterior branch of lower spur smaller, narrower, less spatuliform. 
Carapace, mandibles, and sternum deep brown. Abdomen deep 
black-brown, without any pale dorsal band . . 
. Lower spur on tibia of palpus not divided into branches, but itself 
forming a single branch. 
a, Tibial spur much longer and strongly curved at the apex (see figure) . 
6. Tibial spur much shorter and not curved at the apex (see figure) . .
