three sword -like bristles and a foliate plate ; a comb-like plate of 

 six dark teeth close to the basal process, between it and the 

 olasper. 



Length. — 4 • 3 to 4*5 mm. 



Habitat — Newcastle, Jamaica, W.I. (Dr. Grabham). 



Observations. — Described from several J 's and two $ 's sent 

 by Dr. Grabham. 



It was at first supposed to be Culex secutor, but can at once 

 be told by the two pale spots on the thorax, the more 

 prominently banded abdomen and by the apical segment of 

 the male palpi being longer than the penultimate, not the same 

 length as is the case in C. secutor. Otherwise strongly 

 resembling secutor. It also resembles Culex janitor, Theobald, 

 but this species has unbanded abdomen in the female, and the 

 male palpi have the two apical segments equal, and there is only 

 one pale band. 



The larvae, Dr. Grabham writes, are very different from those 

 of C. secutor.
