probably in search of a suitable situation for a 
permanent abode. When obtained, or perhaps 
when nature calls for sustenance, it makes its 
attacks upon any part of the tree, either trunk 
or branches, leaves or fruit ; all appears to be 
alike that happens to fall in the way, and soon 
after being permanently fixed, it commences 
manufacturing itself a film, which at an early 
state of its process is nearly round, white, and 
downy, which gradually becomes testacious, in- 
creased in size, and altered in form, and when 
attained to its completion the shell is brown, 
about an eighth part of an inch long, obtuse at 
one end, and gradually tapers to the other end : 
it is rather arcuated or bended. The whole is em- 
blematical of a Cow’s horn, except that side which 
adheres to the tree, which is flat. This side of the 
shell is always closely and firmly cemented to 
the tree, I believe without being moved, after the 
commencement of its formation. They will fre- 
quently be found so numerously and closely assem- 
bled as to render it impossible for them to form 
fresh habitations. About the latter end of August 
the parent quits her eggs, which are quite white, 
rather of an irregular long round form, and of the 
amount of twenty to thirty, and shortly after dies 
in the shell. The scale or shell still assumes the 
same appearance, and if not dislodged, would pro- 
bably remain on the tree for several years. About 
the middle of May many of the young are moved 
to (piit the ova, and from this period till about the
