Dr. Annett, the 9’ s i 11 perfect condition. It is a very pretty 
distinct Culex, resembling to some extent the members of the 
genus Janthinosoma, but the legs are not densely scaled, and 
can thus easily be told from species of that genus. The thoracic 
ornamentation resembles G. gelidus, but the thoracic scales are 
much longer in form, and the metallic purple abdomen will at 
once separate it from that species. The specimens were taken 
in the “ bush near the cemetery ” at Bonny. I have only placed 
it provisionally in the genus Culex.
