On the Qnekett excursion to Tring last July our late member 

 Mr. Bird «1 it. — — • ' 1 t" r « » 1 1 1 a pond a large amount of Anacharis alsina- 

 8trum } which appeared to be covered with a mass of [jink-coloured 



ly. On further examination it was seen to be the ova of a 

 water-mite. I took a quantity home with me, which hatched in 

 ,i few days and produced larvae of a species of the genus Eulais — 

 which one I should not like to say, as the genus contains a large 

 Dumber of species all very much alike in the larval stage. The 



Fig. 1. 



in this case were deposited round the stem of the plant, 

 between the leaves, as shown in Fig. 1, a, and when a section 

 was cut through the stems it could be . seen that the eges 

 were arranged two or three deep, in an almost colourless 

 gelatinous film. 



There is another common mite, Llmnesia histrionica, which is 

 also very loud of depositing its eggs on Anacharis; but its 

 favourite position is on the under-side of the leaves (see Fig. 1, b), 

 Tli.' Arrhenuri do uot seem so particular, for although I have had 

 water-plants in the small glass tank in which I have kept females, 

 ,, "'- v " " as ,i " 1 deposit their eggs on the sides of the glass.
