 the day and causes painful swellings. 



Culex quasisecutor. n. sp. 



Thorax deep brown with small dull golden-brown scales,

 extending backwards from them, and traces of pale scales in 

 front over the head, two median short basal lines as in secutor. 

 Abdomen deep brown, with basal pale bands. Legs deep brown 

 wibh prominent apical and basal pale banding to the hind legs, 

 just traces of it on the fore and mid legs. Proboscis unhanded
