and tarsi brown; ungues of fore and mid legs equal and simple, 
rather straight, the mid rather shorter and more curved than 
the fore ungues (hind ones broken); between the claws is a very 
distinct and large yellow empodium. 
Lenr/th .—4 * 5 mm. 
Habitat. —St. Lucia (Low, per Daniels). 
Observation .—Described from a single 9 • It is very marked 
and differs in several respects from any other Culex, especially in 
(i) the long antennae, (ii) the ungues, and (iii) the swollen fore 
and mid femora. I have thus placed it in a separate genus, 
which lies nearest to the Deinocerites from Jamaica, and from 
which it differs in the (a) structure of the antennae, the second 
to fourth joints being scaly and in the joints gradually shortening 
to the apex, (b) in the structure of the ungues and in the swollen 
fore and mid femora, which are of normal size in Deinocerites. 
A number of fresh specimens have been received since this 
description was drawn up. 
Genus SABETHES. Robineau Desvoidy. 
(Page 247, Yol. I.) 
Head clothed with large flat scales; palpi short in both 
sexes, slightly longer in the $ than in the 9 > but never more 
than one-fourth the length of the proboscis; palpi and proboscis 
with large flat scales; antennae 14-jointed in the £ and 9 > 
pilose in both sexes, rather more so in the £ than in the 9 5 
clypeus nude; proboscis of moderate length. Prothoracic lobes 
covered with large flat scales ; mesonotum with small and large 
flat scales, with their apices very convex, back of the mesonotum 
and scutellum with dense large flat scales; metanotum with 
chaetae on the posterior half. 
Abdomen completely covered with flat scales, posterior 
border-bristles very small, the apex in both sexes densely spiny. 
Legs simple in the 9 » hi the £ with dense paddle-like masses 
of scales on one or more pairs; ungues in both sexes small, equal 
and simple. 
Wings with the veins covered with rather broad, dense 
asymmetrical scales; fork-cells long in both sexes ; the stem of 
the first sub-marginal cell extending a long way back towards the 
base of the wing; mid cross-vein a little nearer the apex of the 
wing than the supernumerary; posterior nearer the apex than 
the mid in the £ , less so or nearly in a line with it in the 9 • 
The 9’s might easily be mistaken for Wyeomyias , but they 
can at once be told by the asymmetrical wing scales, whilst in 
Wyeomyia the wdng scales are symmetrical, and by the cross-veins 
in Wyeomyia being like Culex , that is the supernumerary and
