172 A Monograph of Culicidae. 
Wings with the veins clothed with typical brown Culex 
scales ; fork-cells of moderate and nearly equal length and width, 
base of the second posterior cell if anthing slightly the nearer 
the base of the wings; stem of the first sub-marginal about half 
the length of the cell; stem of the second posterior rather more 
than half the length of the cell; posterior cross-vein short, 
nearly twice its own length from the mid; halteres very pale 
ochraceous. 
Length.—4:5 mm. to 5:0 mm. 
d- Ornamented much as in the 9, but the apical silvery 
lateral spots spread far on to the dorsum, and form nearly 
complete apical bands on some of 
the segments. Palpi thin, dark 
brown, the apical joints of nearly 
equal length and with basal white 
bands and with brown hairs, a few 
of the latter on the apex of the 
long antepenultimate joint, which has a pale band 
on the basal half; proboscis with a pale band on 
the apical half; antennae with the plume-hairs 
rich brown. ‘The ungues of the fore and mid 
legs unequal, the larger biserrated, of the hind 
equal and simple. 
Length.—4°3 mm. to 4°5 mm. 
Habitat.—Sao Paulo, Brazil (Dr. Lutz), aud 
Para (Dr. Durham). 
Observations.— Described from a ¢ and ? in 
fair preservation. A number of specimens have 
also been received from Para. It is a very marked 
species, easily told from all Culex with banded 
proboscis by the speckled legs and silvery apical 
lateral spots, which in the ¢ specimen almost 
unite to form apical bands. -It might easily be 

ge mistaken for Taeniorhynchus confinnis (Arribalzaga), 
Fig. 92. | but an examination of the wing scales at once 
Oe shows the difference. In most other points they 
& palpi. exactly agree, but the fork-cells are not relatively 
so long as in confinnis, and the species seem generally of smaller 
size. There is considerable variation in the relative size of the 
fork-cells however.
