lobes, or both. Abdomen densely clothed with flat scales, either 
banded or unbanded. Wings with very small fork-cells, with 
the veins clothed with single or double rows of small broad equi¬ 
lateral scales, abruptly truncated and with lateral clavate or 
elliptical scales to some of the veins (Fig. 272); on the roots of 
the wings are usually some flat scales of more or less brilliant 
hue; costal borders with lanceolate scales projecting from the 
edge (Fig. 272, b); first sub-marginal cell small, smaller than the 
second posterior cell, its base considerably nearer the apex of 
the wing than the base of the latter cell, its stem long, and its 
upper branch more or less closely applied to the first longitudinal 
vein (Fig. 272, 5); the sixth long vein curves at the apex, and the 
incrassation in the anal cell is distinct, almost appearing as a 
true vein. The ungues of the female are simple and equal, 
whilst those of the male are unequal on the fore and mid legs. 
This genus was founded by Arribalzaga for two South 
American species named by him U. pulcherrima and U. Nataliae. 
To these must be added the Aedes saphirinus of Osten-Sacken,

Uranoicienia Trinidadensis, U. domestica, U. caeruleocephala and 
U. pygmaea, mihi. Walker’s Culex argyropus is also apparently 
an Uranotaenia, and (although not presenting the same thoracic 
and wing ornamentation of broad scales) the new species minima
