79 



in the female ; fore and mid ungues unequal, the larger luiiserrated, the smaller 

 also with a basal tooth, hind equal and simple. 



Length. 5 imii. 



Habitat. Middle and Lower Sobat ; Sennar, Blue Nile ; Jebelein, White 

 Nile ; Fashoda ; Kenissa ; Baro ; Pibor. This sjDecies is very conunon on both 

 Niles. 



Observations. Dr. Balfour adds a note as follows : — " Band on the proboscis 

 naiTower and paler than in the female. Thei'e are marked white basal abdominal 

 bands. The white scales on the second segment are arranged like the letter V : 

 abdomen has also white lateral spots." 



Besides the male, which has not been previously described, several females 

 have been sent me by Dr. Balfour. The anterior thoracic ornamentation is not 

 as pronounced as in the type, but wliere the pale scaled area joins the dark it 

 is just the same ; the abdomen is not so speckled on the posterior segments.

Very similar to the type, l^ut with the femora and tibiie of aU three pairs 

 of legs with a row of clear white spots on one side. 



The banding of the legs passes slightl}' on to the apices of the preceding 

 segments above, forming apical pale spots. The tibia; and to some extent the 



femora have black bristles. The Avings 

 (Fig. 4) resemble the type, but there is 

 some variation in the relative lengths 

 of the fork-cells and their stems ; in 

 the ty]3e of this variety the first sub- 

 marginal is considerably longer and 

 narrower than the second posterior cell, 

 its stem less than one half the length 

 of the cell, its base nearer the laasc of the wing than that of the second 

 posterior ; stem of the second posterior half the length of the ceU ; posterior 

 cross-vein about twice its own length distant from the mid. Scales sho-\\ii in

The female only has so far been described, and in general appearance it 

 resembles a Uranotajnia but the larger fork-cells and narrow-curx'ed scutellar 

 scales wiU at once separate it.
