Anopheles karwari. 



Antennae black with silvery hairs. 



Thorax black, covered with numerous snowy white spindle- 

 shaped scales on its dorsal aspect. Three longitudinal dark lines 

 devoid of scales can be made out on the dorsum as well as a lateral 

 eye-like bare spot on each side and a median bare spot posteriorly. 

 Pleurae black with two indistinct longitudinal white lines on each 

 side. 



Scutellum with some scales like those on the thorax and with 

 bristles. 



Abdomen black, thickly clothed with golden hairs ; on the last 

 two segments the hairs are very dense, and a number of scales are 

 also present on these segments, those which project from the sides 

 of the segments being dark coloured and the others golden brown ; 

 the remainder of the abdomen is devoid of scales. 



Wings with the veins clothed with black and white scales 

 forming dark and light areas as follows: The costa shows four 

 large dark-scaled areas and two small ones ; the first longitudinal 

 vein shows dark-scaled areas exactly corresponding to those on the 

 costa except that the large middle area is divided into three by two 

 small white spots. The second longitudinal vein has one dark spot 

 on its main stem and two on each of its branches. The third longi- 

 tudinal vein is white-scaled except for a small dark area at its be- 

 ginning and another at its termination. The fourth longitudinal 

 vein has three small spots on its main stem, and two on each of its 

 branches. The fifth longitudinal vein has one small dark area on its 

 main stem, three on its anterior branch, and one on its posterior. 

 The sixth longitudinal vein shows two dark-scaled areas. The wing 

 fringe is interrupted by light-scaled areas at the terminations of all 

 the longitudinal veins and their branches,
