Stegomyia scutellaris, Walker. 



This species requires to be mentioned, as, although it is 

 not known to have any pathogenic business with man, it is 

 very common in many tropical towns and in many particulars 

 resembles S. fasdata. 



Stegomyia scutellaris is a common house-haunting mosquito 

 in all parts of the Oriental Region, also extending northwards 

 to Japan, eastwards to New Guinea, and south-westwards to 

 Mauritius and the Seychelles. Like S. fasdata, it is active in 

 the daytime and breeds in house-water. It differs from 

 S. fasdata in the colour-marking of the scutum, which consists 

 of a single median longitudinal white stripe. 



The larva is very much like that of S. fasdata; but the 

 scales of the 8th abdominal segment are seven or eight in 

 number and are long and somewhat bayonet-shaped. 



Stegomyia pseudoscutellaris, Theobald. 



This species seems to be very common in Fiji, and is said 

 to haunt houses and to be active in the daytime. It has the 

 median white stripe on the scutum, like S. scutellaris, but 

 is distinguished from that species (i) by the presence on the 

 pleural aspect of the thorax of three parallel white bands, the 

 uppermost of which forms a white lateral border to the 

 scutum on either side ; and (2) by the white bands on the
