LYCOSA. 327 
10. Lycosa brevitarsis, sp.n. (Tab. XXXI. fig. 18, ¢.) 
Type ¢, gynetype 9, in coll. Godman & Salvin. Total length, ¢ 12, ? 15 millim.: 
Carapace brown, with an indistinct, broken, submarginal, yellow band and a distinct, similarly coloured, central 
band, slightly constricted at the base of the cephalic region and again at the posterior eyes, narrowed 
from the central stria to a point terminating behind the anterior central eyes, with a short pale line on 
each side in the cephalic area. 
Abdomen variable in colour: usually olive-brown, with a darker shoulder-spot and a dark, anterior, central, 
lanceolate, dorsal bar, followed by a series of indistinct yellow chevrons, the anterior ones disconnected in 
the middle. Sternum and legs yellow-brown, the latter sometimes indistinctly annulate and brighter on 
the upperside. The palpal bulb presents a barb-like spur similar to that present in other allied species. 
Anterior row of eyes very slightly procurved, almost straight, slightly narrower than the second row. Tarsi i. 
and ii. short, as long as, but not longer than, the sternum, distinctly but slightly curved, and with the 
protarsi densely scopulate beneath. ‘Tibie i. and ii. without dorsal apical spine. Leg iv. short, its 
protarsus not longer than the carapace. 
Coloration of the female similar to that of the male, but the yellow chevrons on the abdomen are usually more 
distinct, Vulval area broader than long, but not so large in proportion as in L. constricta, with the stem 
of the L-shaped process broad at its junction with the cross-piece and broadly dilate to its base. Leg iv. 
similar in proportion to that of the male, short, tibia and patella iv. and protarsus iv. being not longer 
than the carapace.

Panama, Chiriqui (Champion). 
11. Lycosa constricta, sp.n. (Tab. XXXI. fig. 19, 2.) 
Type od, gynetype 2, in coll. Godman & Salvin, Total length, ¢ 9, Q 11 millim. 
Coloration as in ZL. brevitarsis in both sexes, except that the central pale bar on the carapace is not narrowen 
at the cephalic region, but dilate, and occupies the whole ocular area. The dilatation is produced by the 
obliteration of the short dark lines and the fusion of the central portion with the lateral, short, curved, pale 
lines. This difference might be regarded as due to individual variation, were it not for the great 
difference in the form of the vulva. 
Hab. GuatemMa.a, Tecpan (Stoll). 
12. Lycosa longitarsis, sp. n. (Lab. XXXI. fig. 20, 9.) 
Type d,gynetype 2, in coll. Godman & Salvin. Total length, g 11, Q 14 millim. 
Colour very similar to that of Z. brevitarsis, but on the whole paler; the carapace has the central line narrowed 
from the base forward, terminating in a sharp point between the posterior central eyes, with, usually, 
a, small curved pale line on each side in the posterior cephalic portion; the submarginal pale bar is more 
distinct. The markings on the abdomen are paler, while, usually, the lanceolate bar is dark and followed 
to the spinners by a series of yellow chevrons, the anterior pair disconnected in the middle. 
Structure also similar, but tibia i. andii., usually with a small, dorsal, apical spine. Tarsii. and ii. long, nearly 
one-half longer than the sternum, straight, slender, and with the protarsi scarcely scopulate beneath. 
Leg iv. long, the protarsus longer than the carapace, as also are tibia+ patella iv. 
Palpal bulb with a sharp barb-like spur similar in form to that of the allied species. 
Coloration of the female similar to that of the male. Vulval area longer than broad, with the stem of the 
i-shaped process more slender and longer in proportion, not dilate. Leg iv. longer in proportion ; 
carapace shorter than patella and tibia iv. together, not longer than protarsus iv. 
Hab. Mexico, Orizaba, Teapa (H. H. Smith); Guaremata, Tecpan (Stoll); Costa 
Rica, San José (Zogers); Panama, Chiriqui (Champion).
