326 ARANEIDEA. 
Coloration similar to that of L. brunnea, but in the single specimen received (an adult female with an egg- 
cocoon) the markings are very much obscured, as is often the case with examples which have deposited 
their eggs. Sternum and legs not suffused with black. Eyes and other characters as in L. brunnea. 
Vulval area slightly broader than long, cross-piece of the central L-shaped process distinctly longer than the 
stem, which is moderately narrow at the junction, but broadly dilate to the base. 
flab. GuateMata (Sarg). 
6. Lycosa ventralis, sp.n. (Tab. XXXI. figg. 14, 14a, @.) 
Type do, gynetype @, in coll. Godman & Salvin. Total length, ¢ 13, 2? 16 millim. 
Colour of the male practically the same as in ZL. wncata, but the sternum and coxe of thé legs are yellow- 
brown and the entire ventral area is black; the mandibles light red-brown, clothed with grey hairs. 
Structurally, the two spiders are also very similar, except that the barbiform process of the palpal bulb is 
more slender, the barb very sharp, longer when viewed from the outer side, when viewed from above and in 
front presenting itself as a narrow sharp lamina, obliquely situated with respect to its basal portion. 
Tibie i. and ii. with a dorsal apical spine. 
The coloration of the female is very similar to that of the male. The stem of the central L-shaped process of 
the vulva is much broader where it joins the cross-piece than is the case in L. dilatata. 
Hab. Mexico, Amula (H. H. Smith). 
7. Lycosa longivulva, sp.n. (Tab. XXXI. fig. 15, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 20 millim. 
Coloration and general structure as in L. brunnea, except that the sternum and legs are not suffused with 
black. Vulval area much longer than broad, the stem of the central L-shaped process distinctly longer 
(it looks much longer than really so by measurement) than the cross-piece, narrow at the junction, slightly 
dilate beyond the middle, again narrowing to the base. 
fab. Guatemaa, Jalapa (Sarg). 
8. Lycosa lativulva, sp.n. (Tab. XXXI. fig 16, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 20 millim. 
Colour almost as in L. guttatula, but the central band on the carapace is narrow towards the base and strongly 
dilate in front behind the eyes, occupying also the whole ocular area; there is also a very narrow, but 
distinct, pale marginal line. The ventral area of the abdomen has a pale, wedge-shaped, central bar, with 
a dark bar on each side of it. Vulval area broader than long, almost circular, the stem of the L-shaped 
process longer than the cross-piece, which is narrow, strongly dilate towards the base, and again narrowed. 
yes and other characters as in Z. guttutuia. 
Hab. Guatemata (Sarg). 
9. Lycosa dilatata, sp.n. (Tab. XXXI. figg. 17, 17a, 2.) 
Type 3, gynetype @, in coll. Godman & Salvin. Total length, g 14, © 17 millim. 
Colour in the male like that of Z. ventralis, except that the ventral area is pale, with a paler broad median 
band, having a narrower central dusky band running from the genital rima to the spinners. Structurally, 
too, the spiders are similar, except that in the present species the barbiform process of the palpal bulb is 
much longer when viewed from the outer side, otherwise almost identical in form Tibi i. and ii. 
without dorsal apical spine. 
‘The female is similar to the male in colour and general structure. The stem of the central 41-shaped process 
of the vulva is, however, much constricted at its junction with the cross-piece, abruptly broadening, 
forming a circular dilatation. 
Hab. Mexico, Amula (H. ZH. Smith).
