joint longer than the third; fifth joint of an elongated oval form, convex 
and hairy externally, concave underneath, near the middle, comprising 
the palpal organs, which are moderately developed, not very complicated 
in structure, with a crescent-shaped process at the extremity, and are of 
a reddish brown colour. 
In the months of May and June, females of this species, which appears to 
connect the terrestrial with the semiaquatic Lycosæ, may be found under.

by a narrow zone of a slighter texture; it contains 40 or 50 spherical, yellow 
eggs, which are not agglutinated together.

Cephalo-thorax large, convex above, somewhat compressed before, with sligbt 
furrows on the sides, and a narrow indentation in the medial line of the 
posterior region; its colour is brownish black, but it is clad with yel-
