however, to retain the name given by Fabricius and to abolish 

 Villiers' species, as the description is unintelligible and the type 

 has long ago ceased to exist. To save endless confusion the 

 term by which this species is universally known is retained 

 here. 



Regarding its distribution and possible spread Howard* 

 says: "We may expect to find this species everywhere in the 

 moist tropical zone, or at all events, when introduced at any 

 point within the low moist tropics, it may be expected to 

 establish itself." 



It is interesting to note that at present this species is confined 

 in Malay to the ports only. 



Some excitement has arisen from the fact of this insect being 

 carried in banana ships, that it might and even had invaded

 mosquito in question proving to be one of our native species, f 

 It is very unlikely that fasciata would live here if they survived 

 the sudden change of temperature coming from Central America 

 or the West Indies in the banana ships. It is interesting to 

 note, however, that it seems to have invaded New Orleans in 

 that way, and to have occasioned the recent great outbreak of 

 yellow fever there. 



Professor Hubert Boyce and others have shown that in New 

 Orleans and other neighbouring cities and towns fasciata breeds 

 in the large water cisterns seen behind nearly every house,
