Genus Stegomyia. 187 



distinct species, easily told by the single median yellow thoracic 

 line and legs from S. scutellaris, Walker, and by the single, not 

 double line, seen in S. simpsoni, as well as by the legs. It is a 

 very handsome species, and so far nothing like it has occurred 

 outside Natal. Probably it will be found in the Transvaal and 

 other neighbouring regions. Apparently closely related to 

 c/ardnerii, Ludlow, from the Philippine Islands, but easily sepa- 

 rated by the large anterior silvery-white thoracic spot and by 

 the ornamentation of the hind tarsals.
