Small dark mosquitoes breeding in natural 

 waters. 



1. M. funesta. — Costa : six white spots. 

 Basal spots with pale interruption. Wing fringe : 

 pale spots at ends of all the veins, except sixth. 

 Palpi : three bands, the basal one further from 

 the middle one than the apical. A variable 

 species : third long vein may be dark. Resembles 

 listoni and rhodestensis (Fig. 51). 



2. M. listoni. — Third long vein light. Wing 

 fringe, four or more light spots (Fig. 51). Palpi, 

 two broad apical bands further apart than in 

 funesta, one narrow basal. Basal portion of 

 costa uniformly black (characteristic). Attitude, 

 Anopheline-like. Associated with high endemic 

 index in the Duars, Bengal. Larval characters : 

 antennae with simple hair. Clypeal hairs simple. 

 Palmate hairs on thorax and on all abdominal 

 segments. 



3. M. aconita. — aconita = unspeckled, be- 

 cause at the commencement of the third long vein 

 the usual dark spot is absent. Palpi, four bands. 

 Costa, four spots, light interruption in basal spot. 

 Fringe, several pale areas. Anterior forked cell 

 much longer and narrower than posterior. Differs 

 from listoni in palpi. Sumatra, Java. 



4. M. cidicifacies. — Third longitudinal vein 

 dark. Wing fringe, three spots at most. Palpi, 

 three equal bands, two at the joints, one at the 

 apex. Attitude, Cidex-like. Associated with high 

 endemic index of malaria in the Punjab and 

 Madras. Larval characters as in M. listoni. Ova : 

 floats do not touch margin of upper surface 

 (Type i) (Fig. 54).
