trunk and not in the burrow. This is not the only species among those enumera- 
ted that enters the tree from beneath the soil. Bembeciformis and Sphegiformis 
both do the same thing. It might be thought that the object of this is conceal- 
ment since there is no frass or visible opening to betray the presence of a larva, 
but I think the more probable reason is that the bark in this situation being thin 
and soft the little grub has less difficulty in entering here than elsewhere. 
This brings my notes to an end, they are necessarily short and imperfect 
as time has not allowed me to go more fully into the subject. I have therefore 
drawn attention to those points chiefly which are not so generally known, and 
which may enable some other Lepidopterist, I wish there were more such in the ; 
country to fill up some blank spaces in his cabinet. ,
