434 A Monograph of Culicidae. 



one time thought ; the rich green pleurae are very characteristic 

 of the species. The female palp and second antennal segment 

 show the difference between the two allied species mentioned 

 and C. viridis, which I undoubtedly placed all as one in the First 

 Report of the Gordon College Wellcome Research Laboratory, 

 p. 73. 



The specific name viridis was used by Robineau-Desvoidy in 

 1827, for a Culex that cannot be identified. Hence Blanchard 

 has renamed this insect. 



Culex pallidocephala. Theobald (1905). 



First Kept. Gord. Coll. Well. Labs., p. 73 (1905). 



Somewhat like C. fatigans, but the head has rather dense 

 pale narrow-curved scales and numerous dark brown to black 

 upright forked ones. Palpi and proboscis black. Thorax dark 

 brown ornamented with brown and golden-brown narrow-curved 

 scales, the golden-brown forming more or less distinct linear 

 ornamentation and a curved line on each side in front of the 

 wings, which surrounds a dark area in front of each wing. 

 Abdomen black with basal creamy bands. Legs brown unhanded. 

 $ . Head brown, clothed with rather dense pale narrow- 

 curved scales which lie uniformly pointing forwards, a few still 

 paler very small flat scales laterally and long thin bifid upright 

 forked scales over the greater part, those placed laterally jet 

 black, those in the median area dark brown to yellowish-brown, 

 according to the rays of light ; palpi thick, three distinct small 

 basal segments dull testaceous, the swollen apical segment as long 

 as the three basal ones and black scaled ; there may be a minute 

 nipple-like apical segment, but if so it is hidden in scales ; 

 proboscis and clypeus deep brown. 



Thorax dark brown, ornamented with dull golden and deep 

 rich brown narrow-curved scales ; the dark scales form two 

 prominent oval areas, one in front of the base of each wing, the 

 dull golden scales bordering them ; the latter are also more or 

 less placed in lines along the middle of the thorax and others at 

 the sides above the pleurae, others, almost creamy, in front of 

 the scutellum ; scutellum paler brown than the mesonotum, with 

 pale narrow-curved scales and black border-bristles, seven to the 

 mid lobe ; metanotum black ; pleurae black with three patches 

 of white scales.
