Anopheles turkhudi. 



of the thorax are covered with brown scales. The abdomen is of a 

 dark olive green colour, and is covered with many light yellow hairs. 

 The wings are covered with long spindle-shaped scales. 



The costa shows six white-scaled portions ; one of these is 

 apical. 



The first longitudinal vein has white areas corresponding with 

 the outer five white areas on the costa. There is, however, in 

 addition, a small white-scaled interruption at the position of the 

 transverse vein. 



The second longitudinal vein has five white-scaled areas ; two 

 at the position of the transverse veins, one at the bifurcation of the 

 vein and two on its anterior branch. 



The third long vein has two light-scaled portions one at the 

 position of the transverse veins, and the other immediately below 

 the white area on the bifurcation of the second long vein. 



The fourth long vein is white-scaled at its base, and has in addi- 

 tion a white-scaled portion at its bifurcation, and another at the 

 position of the transverse veins. 



The trunk of the fifth longitudinal is white-scaled, except for 

 a single small dark-scaled portion. At its bifurcation it is dark- 

 scaled ; and its branches are dark-scaled, except for one white-scaled 

 portion on each. 



The sixth long vein has a single white-scaled area. The wing 

 fringe is interrupted by light scales at the distal extremities of all 

 the veins except the sixth. 



The legs are dark-scaled throughout, except for a few yellow- 

 ish-white scales at the distal extremities of the femora and tibiae. 



The extremities of the claspers of the male genitalia are of a 

 different shape to those in most other " anopheles." 



Characters of the eggs and larvce. Dr. Christophers has shown 

 that the eggs of this species are very peculiar in that the lateral floats 

 are exceedingly rudimentary and sometimes are scarcely to be made 

 out at all (Fig. 8, p. 39). 



The larvae are also peculiar in that there are, as a rule, no pal- 

 mate hairs on the first three abdominal segments, these hairs being 

 borne only by the fourth to the seventh segments. For this reason 

 the larvae rest at the surface of the water in a somewhat oblique 

 attitude. The shape of the palmate hairs is shown in the figure ; in
