A Monograph of Culicidae. 
Wings with the fork-cells shorter than in the 9 and the 
posterior cross-vein nearer the mid cross-vein. Ungues of fore 
and mid legs unequal, the larger one with two long teeth, the 
smaller untoothed, the hind ones equal and toothed. 
Length. —6*5 to 8 mm. 
Habitat .—Amazon region, Para (Walker). 
Observations .—Described from three nearly perfect specimens 
and one remnant in the old British Museum collection ; it is 
a very dark insect, at first sight resembling Macidus, but its 
venation and scale structure show it to be a Psorophora. 
Walker’s type of Sabethes scintillans is in the Museum, and the 
above description of the 8 is partly based on it. There is also a 
£ in the Hope Collection, taken by Bates in the Amazons.

Head clothed with narrow curved, forked upright, and long 
twisted scales (Fig. 80). 
Thorax with narrow curved scales and long twisted, apically 
expanded scales as in the head. 
Abdomen with dense scales, which stand out, and give it a 
ragged appearance. 
Wings covered with broad pyriform scales, many of which 
are parti-coloured (Plate B). Palpi of the 9 half as long as the 
proboscis; antennae of the 9 14-jointed, including the basal joint, 
of the £ 15-join ted; palpi of the ^ five-jointed, a little longer 
than the proboscis. Wings with the venation much as in Cut ex, 
but the posterior cross-vein is nearer the apex of the wing than the 
mid cross-vein. 
Legs banded, densely scaled with projecting scales ; fore and 
mid ungues of the £ unequal, the larger with two, the smaller 
with one tooth ; hind ungues equal, small, toothed ; in the 9 all 
the ungues are small, equal, thick, and with a short thick 
tooth. 
The members of this genus are large species, and present 
a curious mouldy appearance. The genus is represented in 
Australia, Burma, India, Java, and the West Coast of Africa 
(Fig. 75). Nothing is known of the life-liistory. The chief
