PARDOSA. o19 
cavity, lying close under the margins of the bridge, is a dark, punctate, bean-like piece, of very variable 
form. Figures of the two extreme forms are given on the Plate, but many intermediate varieties occur. 
The two cavities in this species are much larger in proportion to the whole vulval area than in P. prolifica, and 
in this latter species no black bean-like pieces are evident.

4. Pardosa flavipalpis, sp. n. (Tab. XXX. figg. 25, 25a, b, ¢; 26, 2.) 
Type d, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 6, 2 7 millim. 
Colour similar in both sexes. Carapace rich chocolate-brown, with a central orange band, narrowed behind, 
gradually dilate, terminating before the posterior eyes, where there are two small brown blotches, 
sometimes coalescent within the pale band; a bright orange submarginal band, including the external 
angles of the clypeus, the rest of the clypeus being brown, with a central yellow spot. Abdomen brown, 
speckled with yellow, and with the usual lanceolate pale band, margined with black, and the dorsal 
series of paired spots. Ventral area pale yellow, clothed with white hairs. 
Legs bright orange, annulated with deep black. 
Palpus of the male :—Femur orange, the whole middle portion black, patella and tibia orange, tarsus deep black. 
The central process of the palpal bulb is very broad, transverse, and strongly uncate, or reflected down- 
ward, concave at the base beneath, bearing a long (not easily seen) sharp spur, curving upward. 
Vulva of the female very broad, having a little behind the middle of the area a central convex cap, from 
beneath whose margin issues the narrow stem of a somewhat |-shaped process, its arms curving 
forward, forming a small cavity on each side of the stem, where it joins the cross-piece. The position 
of the cap at once distinguishes it from that of P. prolifica, to which at first sight it bears a general 
resemblance. 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith). 
5. Pardosa uncatula, sp.n. (Tab. XXX. figg. 27, 27 a, ¢; 28, 2.) 
Type So, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 4, 9 6 millim. 
Coloration in both sexes much the same as in P. prolifica, but in the majority of the males much lighter, the 
abdomen having a broad, pale, central, foliated band, and the sternum usually pale yellow. The central 
band on the carapace in both sexes extends up into the ocular area. ‘The colour of the palpi of the male 
varies from brown to deep black, the tibia and tarsus being usually deep black and clothed with 
moderately dense hairs, but these segments are not so large in proportion as in P. prolifica. The legs 
are pale yellow and more or less distinctly annulate, sometimes in the male sex, however, they lose the 
annulations almost entirely. 
Palpal organs :—The central process, seen from beneath the segment, is short, broad, with a stout, black, blunt 
spur about the middle of the posterior margin, and a stout hook at the apex. The process lies flat, 
slightly obliquely, but its apex does not nearly reach the outer margin, nor does the black spine, which 
is, however, visible, stretch across beneath it. Seen from the inner side, the hook of the process is 
obviously a thin lamina and the apex looks quite sharp; the basal median spur is very conspicuous, as 
is also another stout black spur on the anterior portion of the bulb. The tarsus is shorter in proportion 
than in P. prolifica, broader and more globular. 
The vulva of the female is characteristic, having the usual small concave cap anteriorly, with a broad, longi- 
tudinal, central groove, which is somewhat dilate where it touches the posterior margin. In its posterior 
half the groove passes between a pair of elongate, more or less regular, convex, parallel, bean-like bosses ; 
but the variation in actual shape is so great; that it is impossible to give any single description or figure 
which would hold good for all the forms. The elongate bean-like bosses are, however, constant.
