406 ARANEIDEA.

Hab. Mexico, Teapa in Tabasco (H. H. Smith '). 
‘In the form of the abdomen, especially of the three nipple-like prominences in 
the upper central posterior dorsal line, this species so closely resembles A. feliz, 
O. P.-Cambr. (P. Z. S. 1880, p. 340, t. 30. fig. 19), from Parana, that I have little 
doubt the two are identical. Without seeing the types, however, and thus being 
able to compare the form of the vulva, one is not justified in regarding them as 
conspecific.

In this genus, which is scarcely separable from Argyrodes, the central posterior eyes 
are, in the typical species, wide apart and closely adjacent to the lateral posteriors, 
while in the typical Argyrodes the central posteriors are further from the laterals and 
closer together. I cannot feel confident that the characters drawn from the curvature 
of the posterior row of eyes are likely to be of much value. ‘The colulus is present 
and very distinct (as in Argyrodes), as well as the tarsal comb on the fourth pair 
of legs. 
The species occurring in the collection before me may be recognized as follows :— 
Females. 
A. Apex of abdomen bifurcate or with a short flagellum. 
1. Apex of abdomen terminating in a shallow bifurcation. Femur i. 
not more than half as long as the abdomen. 
a. Abdomen longer, more slender towards the apex, seen in profile. 
Vulva longer, more conical, less concave beneath. . . . . furcata, O. P.-Cambr. 
6. Abdomen shorter, less slender towards the apex, seen in profile. 
Vulva shorter, less conical, more rounded and more concave 
beneath . 2. 1 1 1. ww we, see ee ee . Otfissa, nom, n.

appendage. Femur i. as long as, or longer than, the abdomen .  projiciens, O. P.-Cambr.
