Anopheles gigas. 



There is an additional white spot on the posterior branch near its 

 termination. 



Third long vein with light scales near its inner extremity, and 

 also at its outer extremity ; otherwise covered with dark brown scales. 



Fourth long vein covered with dark scales except for a light 

 spot on each of its branches ; the spot on the anterior branch is on 

 the middle of its course ; the spot on the posterior branch is at its 

 outer extremity. 



Fifth long vein for the most part covered with dark scales, 

 except at its bifurcation where there are white scales. There are, 

 in addition, two light-scaled areas on its anterior branch. 



Sixth long vein covered with dark scales except at its tip. 



The wing fringe is interrupted by light scales. 



The legs are for the most part covered with dark scales. 

 There are light scales at the distal extremities of the femora and 

 tibiae in all the legs. The hind femora have a characteristic broad 

 white band in the middle third of their length. 



Characters of the larva. Dr. Christophers states that the 

 larval antennae of this species are provided with a small rudimentary 

 branched hair somewhat like the branched hair on the antennae of 

 the larvae of barbirostris and nigerrimus. The frontal hairs are 

 simple and unbranched. There are no thoracic palmate hairs. 



Habitat and observations. This species appears to occur only 

 in hill districts. A few specimens were obtained at Reneghat 

 (Bengal) at an elevation of about 4,000 feet. It also occurs at 

 Bakloh (6,000 feet) in the Punjab, and at Naini Tal (6,500 feet).

Anopheles gigas (Theobald). 



We regret that we have not been able to obtain specimens of 

 this mosquito. The following description is extracted from Mr. 

 Theobald's Monograph, Vol. II, p. 308. 



Thorax fawn-coloured in the middle, dark brown on each side ; 

 abdomen dark brown ; legs dark brown with basal pale bands, pale 

 at the base ; wings with two large black spots along the costa and 

 black patches on the wing field ; fringe with pale areas.
