 S. crystallina, Edw. 

 Professor Allman lately sent me sketches of a DnpJim'a obtained by 

 him during autumn in a little subalpine lake near Killarney, where it 

 was in profusion adhering to the under sides of the leaves of the water- 

 lily {Niimphaa aiha). On the sketches being transmitted to Dr. Baird of 

 the British Museum, he at once recognised in them the D. crystallina, 

 Miill. {sida, Straus), adding that he had met with the species but in two 

 localities — -near London — and in both sparingly.
