examined I)}- the writer l)ut several larvae were found in mate- 

 rial from both clay and mud bottoms. A single larva of 

 NympJmla was found at a depth of nine feet on a mud bot- 

 tom. Elophila was collected on a boulder bottom in shallow 

 water. The larvse collected in these bottom deposits were evi- 

 dently washed from their usual habitat on the lily leaves and 

 sank to the bottom (see Welch, '16, p. 171, etc.). Dr. Welch 

 has made a study of these aquatic larv?e from parts of Oneida 

 Lake and his report will contain a full account of these inter- 

 esting insects. Identifications by Dr. Paul S. Welch.
