I have once more to express my gratitude to Mr. "W. R. Jeffrey, 
of Ashford, for persevering aid in carrying on my observations on this 
species, by means of which I am in a position to offer several particu- 
lars as additions to my former paper in the February No. of Ent. Mo. 
Mag. for 1876 (vol. xii,p. 210). That paper contained descriptions of 
the larva, and of its case when made from Potamogeton , and was sup-

polyphagous, and not confined to Potamogeton only. I have the 
pleasure of commencing my present notes by furnishing a full confir- 
mation of this belief ; I shall then relate in detail the movements of 
larva?, which I watched very carefully and minutely while they w r ere 
engaged in case-making. I have to give an account of a moult which
