32 A Monograph of Culicidae. 



covering distal third, becoming short and start at the apex ; a 

 light area at base of three distal segments, giving a slightly 

 banded appearance ; two distal segments spatulate, proboscis 

 scaled except labella, labella covered with median stout setae, a 

 few light hairs at apex. 



Thorax : prothoracic lobes dark ; mesothorax dark brown at 

 sides, with scattered light hairs, a broad light brown patch in the 

 middle ; within this light area a median line and obscure lateral 

 lines i scutellum light with single horizontal row of hairs ; 

 metanotum dark without hairs ; halteres dark covered with 

 thick pubescence and emarginate scales, stalks light without 

 scales. 



Abdomen, basal area of each segment light, covered sparingly 

 with long, light hairs ; two stiff hairs on posterior margin of 

 distal segment, stout hairs on margin of genital lobes. 



Legs, coxae and trochanters light, the latter, femora, tibiae 

 and tarsi covered with short, dark, emarginate scales and setae ; 

 ungues of front legs very unequal, the larger ones with a large 

 median tooth and small basal lobe ; median ungues curved, with 

 blunt basal lobes ; posterior ungues equal, simple ; posterior 

 metatarsus slightly longer than tibia. 



Wings with dark costa, with two distinct, nearly equal, 

 yellow spots, one at distal end of sub-costal vein, one at and 

 involving distal end of first long vein ; fringe dark, with a yellow 

 spot at the end of each vein except at the end of the sixth ; the 

 first spot carried on to the first long vein, the apical spot carried 

 past over long vein on to the upper branch of the second long 

 vein ; the second long vein dark except for a few basal light 

 scales ; third long vein yellow in the middle, dark at the base and 

 apex ; light area at base of third long vein carried over the 

 fourth on to upper branch of the fifth, with a few light scales at 

 base ; main branch of fifth long vein light, except at base and 

 apex ; distal half of sixth dark, except at apex, basal half light ; 

 sub-costal with a light spot carried to the first long vein (in one 

 specimen the light spot on sub-costal missing) ; third long vein 

 prolonged into basal cell ; first sub-marginal cell longer and 

 slightly narrower than the second posterior cell, stem twice the 

 length of the cell ; stem of second posterior cell prolonged to base 

 of wing; supernumerary cross-vein adjacent to or but very 

 shortly removed from mid cross-vein and equal to it in length 

 when removed nearer to apex of wing; posterior cross- vein a 

 little longer than mid cross-vein and varying in distance from it
