curved scales, also the scutellum. Wing scales broad and short, 

 especially on the first and the second long veins, more elongated 

 on the third and fourth, the lateral ones of the fifth long and 

 thin ; £ palpi short, two-jointed, but with traces of two notches 

 near the base, apical segment as long as the rest of the palp, 

 pointed ; antennae of the 9 normal. The $ palpi long, longer or 

 shorter than proboscis, acuminate, three-jointed, the two apical 

 segments equal, or nearly equal, a characteristic process towards the 

 base. Male antennae with striking peculiarities, the sixth segment 

 with a large tuft of long narrow flat plates on the outer side, the 

 seventh and eighth with small tufts on the inner side, the ninth 

 with a long hook-like process, the next two segments with the 

 inner verticil late hairs partly darkened and denser than the rest.

At the junction of the verticillate hairs at tenth, eleventh, twelfth, 

 and thirteenth segments are two small curved pectinated pro- 

 cesses. They are present on all the other segments, but are not 

 so pronounced. 



This genus is very distinct, especially in the male sex, o wing- 

 to the strange antennal processes. The wing scales and palpi of 

 the female will at once separate them from Culex, which they 

 resemble at first sight. What the function of the extraordinary 

 male antennal processes is we do not at present know. 



Four species occur in this genus, two from New Guinea, one 

 from Singapore, and one from Ceylon. 



The structure of the antennal organs of the male differ in 

 each species.
