LEUCAUGE. 439 
species common in the neighbourhood of Rio Janeiro. The examples of this latter, 
from the Keyserling collection, now before me, are closely allied to Argyroepeira 
hortorum, but specifically distinct therefrom. They do not possess the cusps beneath 
the tibis and protarsi i. and ii. which are noticeable in A. argyra (Walck.). 
For the present I accept McCook’s identification of ZL. venusta, Walck., which he 
regards as equivalent to LZ. hortorum, Hentz. Emerton’s identification of this latter 
species must also be accepted as correct ; and, since there can be no reasonable doubt 
that the two species figured by McCook and Emerton are identical, the name venusta 
has precedence over hortorum. 
The species known to me from Central America may be recognized by the following 
characters :— 
Males. 
A. Tibia of the palpus as long as or longer than the tarsus. 
a. Mandible, seen in profile, more or less deeply indented close to 
the apex. 
1. Mandible very deeply indented at its apex. Conductor (c) of 
bulb bearing a short sinuous process at the apex . . . . mandibulata, sp. nu. 
2. Mandible much less deeply indented at the apex. Conductor (c) 
of bulb without a process at the apex . . . . . . . . Jlongipes, sp. n. 
5. Mandible, seen in profile, not indented near the apex, evenly 
convex. 
a’, Mandible with a cluster of black curved bristles in front 
towards the apex. Conductor and embolus of palpal bulb 
simply sinuous, not enlarged . . . . 2. . . venusta, Walck. 
b'. Mandible without a cluster of bristles in front towards the 
apex. Conductor and embolus enlarged and membranous at 
their apex (see figure) . . . . . . . . . « . . . aurostriata, O. P.-Cambr. 
B. Tibia of palpus much shorter (one-half or one-quarter) than the 
tarsus. 
a’. Tibia of palpus twice the length of the patella. Mandible 
attenuate towards the apex, with numerous long stout bristles 
on the inner anterior side, and a series of curved bristles, 
besides hairs, on the outer side . . . . - . . . setigera, sp. 0. 
_ &. Tibia of palpus scarcely longer than the patella, Mandible 
simply convex to the apex, not attenuate; without stout 
bristles in front or curving hairs on the outer side, a few short 
fine hairs only present. . 2. 2. 1. 2. ew ee eee meerens, O. P.-Cambr. 
Females. 
A. Abdomen striped longitudinally. 
a. Abdomen presenting a central clear stripe with two median diver- 
ticula on each side and also two longitudinal lateral stripes.
