28 LYCOSID/E. 
brown spots, disposed alternately, both of which converge to the spinners; the sides are 
mottled with black ; and the branchial opercula are of a dark-brown colour. 
The male is much smaller and darker coloured than the female. Its cephalo-thorax is 
black, with a white band extending along the middle, the pale lines near the margins being 
almost obliterated. The falces are of a very dark, reddish-brown colour ; the maxillse have a 
red-brown hue; and the sternum is black. The abdomen is black, with a tinge of brown on 
the under part, and a profusion of white hairs on the upper part. The legs are long and 
slender, and the thighs have a brown-black hue, except at the extremities, which, with the 
tibiae, metatarsi and tarsi, are of a pale-brown colour. The palpi are black; the cubital and 
radial joints are short, and the latter, which is the larger, is abundantly supplied with black 
hairs; the digital joint is of an oblong-oval form, convex and hairy externally, and concave 
within, at the base; this concavity comprises the palpal organs, which are moderately 
developed, with a prominent, slightly curved, pointed spine, directed forwards, and are of a 
dark-brown colour, approaching to black. 
The description of Lycosa luyubris, given by M. Walckenaer, is applicable to the male 
only. Among the synonyma of this species he has included the Lycosa meridiana of M. Hahn 
( £ Die Arachn.,’ Band i, p. 20, tab. 5, fig. 16), a spider decidedly superior in size and unlike 
it in colour, and has placed the Lycosa sylvicultrix of M. Koch, which is identical with Lycosa 
luyubris, among the synonyma of Lycosa vorax Hist. Nat. des Insect. Apt., tom. 1, 
p. 313). 
M. Koch states that the male of Lycosa alacris (Lycosa luyubris) has a fine, red spot on 
the back of the digital joint (des Endgliedes) of the palpi (‘Die Arachn./ Band xv, p. 41); 
but this must be a very unusual circumstance, as among several thousand males not one may 
be observed to possess this character. 
Lycosa luyubris abounds in the woods of Denbighshire and Caernarvonshire. The sexes 
pair in April and May, and in the latter month the female deposits about fifty spherical eggs, 
of a pale-yellow colour, not agglutinated together, in a cocoon of a lenticular form and 
compact texture, composed of silk of a dull-greenish or yellowish-brown hue, and encircled by 
a whitish zone of a slight fabric; it measures one fifth of an inch in diameter.
