Time of capture. —March (Grabham) (11). 
Habitat. —J amaica. 
Observations. —Described from a series sent by Dr. Grabham. 
It is very close to TJ. Nataliae of Arribalzaga, but differs from it 
in having only one pearly abdominal band. 
The species can easily be told from the other Uranotaeniae of 
the West Indies and South America by this character and by 
the unbanded legs, with the white knee and tibial spots which 
sometimes show pale blue. Dr. Grabham writes: “ Found in 
association with Anopheles larvae in stagnant permanent pools, 
about the Kingston district. I have not been able to persuade 
this form to feed from my Anger when placed in the netting of 
the breeding jar.”
