Anopheles fuliginostts. 



in the Punjab (Lahore, &c.), in Madras, and several places on 

 the East Coast, in the Central Provinces (Nagpur, &c. ), in Southern 

 India ( Travancore), in Bombay, in the Berars ( Ellichpur , and in Goa. 



In Calcutta it was the commonest species in the Fort, and in 

 Nagpur it was also found in large numbers in the houses ; in other 

 places it is rarely found in houses, and approaches in habits to 

 barbirostris and niyerrimus. 



In Nagpur and in Madras its larvse were found in large 

 natural ponds with grass and weed at the edges ; in the Punjab 

 its larvae occur along with those of niyerrimus and barbirostris 

 in shady, weed-grown pools under trees. In Bombay it is fre- 

 quently found in tanks. 



The characters of fuliginosus are sufficiently well marked 

 to easily distinguish it from other Indian species ; the white patch 

 near the lower end of the femur in the mid legs is a very constant 

 and characteristic marking. 



Variations. Major Adie, I.M.S., has noted that the number 

 of white bands on the palpi and the number of pure white hind 

 tarsi, as well as the distribution of white scales on the veins of the 

 wings, are not by any means constant in this species. A common 

 variety having four white palpal bands and two white hind tarsi is 

 found in the Punjab throughout the winter. This variety, if 

 examined alone, might easily be taken for a new species, but breed- 

 ing experiments have shown that it is not so. An interesting 

 observation by Major Adie, confirmed by one of us, is that at the 

 end of the autumn in the Punjab the ordinary form of this mosquito 

 is gradually replaced by the variety with four white palpal bands 

 and two white hind tarsi, and that in the spring a return to the 

 ordinary form occurs an excellent instance of " seasonal variation " 

 in mosquitoes.
