 Microscopical characters. 



Head black, with white flat scales laterally and creamy white, narrow curved 

 scales in the centre and extending towards the nape ; many upright forked scales 

 are also present over the whole surface, the lateral posterior ones being some- 

 what narrower and black, the rest being broader and with pale apices ; a few 

 dark bristles project between the eyes. Clypeus deep brown, almost black. 

 Palpi and proboscis black. Antennae pale brown. Thorax uniformly purplish 

 brown, clothed with narrow curved scales of a rather lighter colour ; on the 

 anterior margins are several white, curved scales ; in the 

 centre is a dark line running almost to the scutellum ; on 

 either side of this line and about half way between it and the 

 margins is a single row of bristles ; there are also some rather 

 stronger bristles irregularly arranged along the" margins, but 

 more numerous over the wing-roots. Scutellum with similar 

 colouring to that of the thorax, the mid lobe with six bristles 

 and the lateral lobes with four. Metanotum dark brown. 

 Halteres with pale stems, thickly covered with pale scales, 

 the apices with small dark flat scales. Abdomen — first segment 

 black, bare, except for two small median patches of dark 

 flat scales and a number of golden bristles, most of the latter 

 arising more or less in the centre and spreading out laterally ; 

 second and third segments with black scales and very marked 

 apical curved white bands not quite reaching to the lateral 

 margins ; fourth segment similar, but the band just reaching the 

 edges ; fifth also similar but having in addition small apical lateral 

 spots : sixth and seventh with apical, lateral, spots only ; last 

 segment black ; venter mostly pale scaled. Legs almost 

 black, unhanded ; femora pale ventrally. f-Finffs with the veins clothed with 

 brownish scales ; the median ones on the subcosta and first longitudinal vein 

 being very broad, those on the other veins as in Culex ; the lateral scales 

 on all the veins shoi't with blunt apices, somewhat resembling those of
