On a Larva Form of Insect. 
By C. Tomss, Esq. 
We have received a very interesting communication 
from Mr. C. Tomes, on the subject of a larval form of 
insect, referable, in all probability, to the genus Hydroptila, 
which is remarkable for the curious and beautiful cocoon it 
forms of a silky material, covered on the exterior with por- 
tions of a Conferva arranged in a remarkable manner. A 
brief notice of apparently the same object, was given to the 
Dublin Microscopical Club by Dr. John Barker, as reported 
in our January number. 
Mr. Tomes’s paper was, unfortunately, put into our hands 
too late for insertion in the present number, but will appear 
with full illustrations by Mr. Tuffen West in our next.
