black and white, with black plumes, the last two joints short and

and a few black ones ; black scales on each lateral lobe; meta- 
notum deep purplish-brown, with a testaceous tinge at the sides ; 
pleurae deep brown, with scattered white scales. 
Abdomen with the first few segments almost entirely covered 
with creamy-yellow scales, apical ones with purplish-brown 
scales, the apical borders with yellow scales and some white ones 
at the sides, and a few white scales dotted over the base of the 
last two segments. 
Legs and wings as in the 9 • Ungues of the fore and the 
mid legs large, black, unequal, the larger only with a distinct 
tooth ; hind ungues equal and simple. 
Wing fringe purplish-brown, white in some lights at the 
ends of the veins. 
Length .— 3*5 mm. 
Habitat .—British Guiana (Rowland); Brazil (Lutz); Argen¬ 
tine (Arribalzaga) ; Madras (Cornwall); Perak (Wray). 
Time of capture. —Pebruary, in British Guiana. 
Observations .—I have examined several specimens from the 
above localities and can find no differences except in slight colour 
variations. This species can at once be told by the curious tuft 
of long scales on the mid and hind femora, and by the three 
white spots on the costa, and the broken white bands arising 
from them, on the densely broad-scaled wings. In the 
Guiana specimen the proboscis has a few yellow scales at the 
base and is black at the tip, there being two distinct white 
bands ; the antennae are also more distinctly broadly banded 
with black and white, and the wings are slightly darker than in 
the Malay specimen, and the hind femoral tufts are more distinct, 
and traces may also be seen in the fore legs, probably in the 
single Malay specimen they are denuded. The specimens given 
me by Captain Cornwall from Madras are somewhat darker than 
the Malay specimen also, and some show two rather indistinct 
black spots of scales on the mesothorax, and the centre of the 
mesonotum has a broad band of yellow scales and traces of a 
third band on the proboscis. Some specimens from India show 
two white costa-l spots only. 
In all respects these specimens answer to Arribalzaga’s Aedes
