Mr. Knab spoke of the finding, by Mr. J. B. Van Duzee, 

 of a psychodid larva in water between the leaves of a Bromelia 

 in Florida. The adult, on examination, seemed to be a new 

 species. Another psychodid larva he himself found to be very 

 abundant in moisture at the margin of a sewer outlet in Mex 

 ico. Mr. Barber referred to his former note before the Society 

 (see p. 102) on a blood-sucking psychodid, Flebotomus sp., 

 found in Guatemala, and stated that a species of Flebotomus, 

 had lately been discovered by him at Plummers Island, Mary 

 land, and that this species had the same annoying habit.
