276 A Monograph of Culicidae. 
antennae are swollen ; they are 14-jointed. Proboscis scaly, apex 
expanded, not as long as the antennae. Venation as in Culez, 
the fork-cells rather long; scales (Plate D., Vol. Plates) rather 
large. Legs with the fore and mid femora large, ungues of 9 
equal and simple, in the ¢ the fore and mid slightly unequal, 
the larger uniserrated and much curved in the fore legs; the 
smaller simple; the larger uniserrated in the mid legs, the 
smaller simple; hind ungues equal and simple. 
The essential characters of the genus are the long scaly 
antennae, especially the elongated second joints and the pilose 
nature of the feelers in the ¢. 
So far the genus is only represented in the West Indies by 
probably two species. It is certainly the most aberrant genus 
in the Culicidae, both in structure and habits.
