mid united at an angle, the third Ions: vein not being carried 
0 5 o o 
through into the basal cell, whilst the second long vein is carried 
past the humeral cross-vein. 
The genus Sabethes comes in the sub-family Aedeomyina, the 
palpi being short in both sexes ; having chaetae on the metanotum, 
they resemble Wyeomyia. This latter genus is very close to 
Sabethes, but the peculiarity of the wing scales and cross-veins is 
sufficient to separate them. Until Dr. Durham brought back 
some fresh material from Para I could not make a proper 
examination of any member of this genus, the two ’s I 
examined being mounted in such a way that I could not detect 
the metanotal bristles or palpi, and I had seen no females. 
Moreover, I was not, until Dr. Durham’s material arrived, certain 
of the sex of the two specimens I had seen. One in the British 
Museum was labelled a 9 of S. remipes . Not being able to see the 
genitalia I was unable to decide to which sex it belonged ; it sub¬ 
sequently proved to be a £, the 9’ s having simple legs, not 
armed with paddles. 
Dr. Durham informs me Sabethes are most brilliant when on 
the wing and that they are not purely sylvan. Those that he 
took came into the hut in which he and his companions were 
making observations.

9 . Head clothed with flat dark brown scales; antennae 
dark brown, almost black basal joint with grey tomentum ; palpi 
short dark brown, with metallic reflections; clypeus with grey 
tomentum; proboscis black. 
Thorax black, clothed with small flat bronzy green, dull 
purple and a few blue scales; scuteilum with deep violet to 
black scales ; metanotum black ; pleurae black. 
Abdomen covered with deep metallic purplish black scales ; 
venter pale dull yellowish ; apex bristly. 
Legs deep metallic violet, brown and purple ; in the mid legs 
the ventral surface of the first, second and third tarsi, silvery 
white, apical one black ; ungues equal and simple. 
Wings with the veins clothed with typical Sabethes scales; 
fork-cells long; the first sub-marginal cell longer and narrower 
than the second posterior cell, base of the latter a little nearer 
the base of the wing than that of the first sub-marginal; stem 
of the first sub-marginal less than half the length of the cell; 
stem of the second posterior cell also less than half the length of 
the cell; mid cross-vein nearer the apex of the wing than the 
supernumerary, posterior cross-veins a little nearer the apex than 
the mid and longer than the mid; second long vein carried past 
the humeral cross-vein.
