tarsi with distinct and equidistant pale yellowish rings; terminal 
segment uniformly yellow. 
Wings (fig. 7).—Clothed with black and yellow lanceolate scales; 
costa with five spots, all extending on to the first long vein, the 
third spreading evenly on to sub-costa, but interrupted on the first 
long vein by a group of yellowish scales near the proximal portion. 
Second vein with black patches of scales immediately before and 
after the cross vein, upper branch of the fork except at the base and 
extreme apex black scaled, lower branch with a pale spot at the 
base, then a short black patch, and the remaining portion clothed 
with pale scales, some of which are tinged with black. 1 hird \ein 
entirely yellow scaled, with the exception ol a few black scales at 
the extreme base and apex. Stem of the fourth longitudinal vein 
with a large spot just before the fork, a few black scales behind the 
posterior cross vein and at the base ; upper branch with two spots, 
lower branch with one median dark patch. Fifth long vein with a 
few black scales at the base of the wing, the rest being yellow; 
upper branch with a small black patch at the base, a larger one at 
the apex and another in the middle; lower branch completely 
yellow scaled, except for a small black spot at the apex. Sixth 
vein with a yellow patch towards the base, the remaining portion 
black scaled. Fringe with pale areas at the apices of the veins. 
Length . — 3 mm. 
Habitat. —This interesting Anopheline was captuiccl by r - 
A. S. Donaldson at Broomassie, W. Africa. 
It is markedly distinct from any other hitherto described species 
of Cellia, and may be readily distinguished by the very conspicuous 
and regularly disposed rings on the mid and hind legs. It may 
be further distinguished also by the rough outstanding scales 011 
the palpi. The only specimen which we possess is in a splen i r 
state of preservation so far as it goes, but, unfortunately, both the 
anterior legs and the apical segments of the palpi are wanting.
