perhaps be only the corneous margin of the posterior lobe of the 

 palpal bulb. 



The fakes are small and of a yellowish colour ; the maxillce 

 straight, short, broad, and rounded at the outer extremity ; the labium 

 is small and pointed at the apex ; these parts are blackish brown, 

 edo-ed 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 

 yellowish-white 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 trans- 

 verse surface of the inframamillary organs ; but there are no cala- 

 mistra on the legs, the latter being seldom (never in my own expe- 

 rience) found in the male sex. 



A single example of this very distinct JJloborus was found on a 

 low plant on the way up the Nile between Cairo and Siout.
