Anopheles culicifacies. 



The palpi have three small, almost equal, yellow areas, namely, 

 at the apex, at the joint between the third and fourth segments, 

 and at the joint between the third and second segments. 



The head is covered with yellowish-white and brown upright 

 scales, and has a small frontal tuft of white hairs. 



The thorax is covered with brown and yellow hairs and hair- 

 like scales inserted on a dark back-ground. There is a distinct 

 median, dark, longitudinal line. The lateral aspects of the thorax 

 are darker than the dorsum. 



The abdomen is of a dark brown colour and is covered with 

 long yellow hairs but is without scales. 



The wing is covered with narrow spindle-shaped scales. 



The costa has five yellowish -white scaled portions, the innermost 

 of which is of very small size ; the outermost is apical in situation. 



The first longitudinal vein shows five small yellow-scaled areas 

 corresponding exactly with the similar costal areas. 



The second long vein has three light-scaled portions, the two 

 inner are situated at the transverse veins, while the outer is situ- 

 ated at the bifurcation of the vein, and involves, for a short 

 distance, both branches. 



The third long vein is dark-scaled throughout, except at its origin. 



The fourth long vein has three light-scaled areas, one towards 

 its inner end, one at the situation of the transverse veins, and one 

 at the point of bifurcation ; the light-scales are continued on the 

 branches for a short distance. 



The fifth long vein has only one light scaled area on the main 

 stem, and one on each of its branches. 



The sixth long vein has one light-scaled spot. The distal ex- 

 tremities of the posterior branch of the fourth longitudinal, and the 

 anterior branch of the fifth longitudinal are alone light-scaled, and only 

 at these points is the costal fringe interrupted by lighter scales. * 



The legs are of a dark brown colour throughout, but some- 

 times show, at the distal extremity of the tibia, a small spot of 

 yellowish scales. 



Variations. There may be (1) an increase in the number of 

 light-scaled interruptions in the wing fringe; (2) a tendency to 



* These two light-scaled areas on the wing fringe are sometimes indistinct. This is shown 

 in the wing of the right side in the specimen from which the coloured plate was drawn.
