Pseudoficalbia THEOBALD, Trans. Linn. Soe. London, Zool., vol. 15, p. 89, 1912. 
A small genus, mainly of tropical distribution. The larvae live in 
ground pools, and have a superficial resemblance to Anopheles, from 
the elongated black head, and the habit of lying flat in the water, 
although the larvae are not surface feeders. The adults are orna- 
mented with lines of metallic blue scales.
