ARCTOSA. 331 
Legs yellow, clothed with grey hairs, the femora with two distinct dorsal annuli and a faint basal dusky 
mark; the basal two-thirds of the patella brown; the tibia with a basal and subapical brown annulus ; 
the protarsi with basal, median, and apical brown annulus. 
Abdomen dark olive-brown, with an anterior white shoulder-spot on each side, encircled in front with black, 
followed by a series of indistinct pale spots on each side; ventral area and sternum pale yellow, with 
grey hairs. 
For figures of the palpal organs and vulva, see Plate. 
Hab. Mexico, Teapa (H. H. Smith); Guatemata, Santa Ana (Sarg), Guatemala city 
(Stoll). 
Found under boulders of rock in a river-bed (Sarg). 
2. Arctosa minuta, sp.n. (Tab. XXXTI. figg. 26, ¢; 27, 2.) 
Type d, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 7, 9 7 millim. 
Colour and pattern similar in both sexes. Carapace and legs dull brown, mottled and annulated with grey 
hairs. (In alcohol the pale mottlings appear dull yellow.) Sternum and ventral area of the abdomen 
dull yellow-white. 
For figures of the palpal organs and vulva, see Plate. 
Hab. GuaTEeMALa (Sarg). 
Very similar in coloration to A. trifida, but much smaller, and with the central 
pale mottled portion on the carapace larger. The form of the vulva is variable, and 
the palpal organs very slender and difficult of observation. 
3. Arctosa cinerea. (Tab. XXXI. figg. 28, ¢; 29, 2.) 
Aranea cinerea, Fabr. Ent. Syst. 11. p. 423°. 
Lycosa cinerea, Emerton, Trans. Conn. Acad. vi. p. 488, t. 47. figg. 3, 3 a, 6 (1885) *. 
Trochosa cinerea, Banks, Proc. Calif. Acad. Sci. (3) i. p. 272°. 
Hab. Nortu America, Massachusetts, Connecticut, and Indiana?, California ?.— 
Mexico, Tepic, Orizaba, Vera Cruz 3.—Evrops '. 
Our figures are taken from specimens found near the River Severn in Wales. I 
should doubt that Emerton’s North-American examples are really conspecific with the 
European A. cinerea (Fabr.). Banks’s Trochosa cinerea is, I suspect, identical with 
the A. trifida here described. 
4, Arctosa mexicana. 
Trochosa mexicana, Banks, Proc. Calif. Acad. Sci. (3) i. p. 272, t. 17. fig. 4 (9) * 
Type, @, in coll. Calif. Acad. Sci. Total length 9 millim. 
Hab. Mexico, Tepic?. 
I do not know this species, and it may fall into the Trochosa-group of which 
T. ruricola (De Geer) is the type. According to Banks’s description and figure, 
however, the vulva presents a transverse elliptical cavity, with apparently no L-shaped 
process nor any dividing septum.
