202 A Monograph of Culicidae. 



Antennae with the basal segment dirty yellow; the inner 

 face is rather thickly clad with small flat scales, with a few dark 

 ones interspersed ; the basal half of the second segment is similar 

 in colour to the basal segment ; the apical half and the succeeding 

 segments of the antennae are black, covered with numerous short 

 white hairs ; verticillate hairs black ; last segments of antennae 

 not elongated. 



Clypeus dark brown, a few narrow white scales on its anterior 

 margin. Palpi black scaled, four-jointed ; third segment very long 

 — longer than all the other segments put together ; fourth segment 

 minute. The palpi are unusually long, being fully half the length 

 of the proboscis. 



Proboscis thick, entirely black scaled. Prothoracic lobes 

 thickly clad with flat spatulate scales, white on the lower half, 

 black above, and from the apex a tuft of short dark brown 

 bristles projects. 



Mesonotum yellowish-brown; running around the margin 

 anteriorly and laterally as far as the wing bases is a creamy line, 

 composed of broad-curved scales ; the rest of the mesonotum is 

 densely clad with long, narrow-curved, bronzy scales, which are 

 especially dense and long over the roots of the wings, where they 

 form dense tufts. The colour of these scales under a hand lens 

 is metallic bronze, but under a two-third power many appear 

 pale brown. In some lights they appear purple ; so do the dark 

 scales on the head and proboscis. Indeed, the scales in this 

 mosquito show a play of colours on every part as the angle of 

 the light changes. 



Pleurae brownish, clothed with tufts of white elliptical scales. 



Scutellum clad with flat black scales, purple or rose-purple in 

 a good light, on all the lobes ; border-bristles brown. 



Wings clouded, covered with dark brown scales, the lateral 

 linear with square ends, the median also rather narrow ; fork- 

 cells moderately long ; stern of the first sub-marginal cell about 

 two-thirds the length of the cell ; base of the cell nearer the base 

 of the wing than that of the second posterior cell ; the second 

 posterior cell is a little broader than the first sub-marginal ; 

 median and supernumerary cross- veins meeting at an angle ; 

 posterior cross-vein rather short, distant about twice its length 

 from the median. 



Legs with the coxae pale ; fore and mid coxae with brown 

 and white scales, the hind with only white scales ; femora pale 

 scaled beneath, though on the fore legs there are dark scales
