The fedces are small and of a yellowish colour; the maxilla straight, short, broad, and rounded at the outer extremity; the labium is small and pointed at the apex; these parts are blackish brown, edged and tipped with pale whitish yellow; and the sternum is dark-yellow- brown and of an oval form. The abdomen is oblong-oval in form, somewhat gibbous above from the middle forwards; its colour is black or nearly so; the fore half has a narrow white yellowish marginal stripe on the upper-side ; and on the hinder half are four small, but distinct, elongate yellowishrwhite oblique spots forming a square ; another spot of a similar colour is placed just above the spinners ; the underside has two longitudinal yellowish bands running nearly throughout its whole length. The spinners are compactly grouped, those of the inferior pair being longer and stronger than the superior ones, which are two-jointed ; immediately in front of the inferior pair is the transverse surface of the inframamillary organs; but there are no calamistra on the legs, the latter being seldom (never in m y own experience) found in the male sex. A single example of this very distinct Uloborus was found on a low plant on the way up the Nile between Cairo and Siout. Fam. THOMISIDES. Gen. THOMISUS, Walck. ad partem. THOMISUS LATERALIS.
