STROM ATIUM ? sp. 381 

in length bored downwards and confined to the stem 
only, Gallery slightly winding. 
2nd—Old Gallery.—The eggs were probably laid upon the 
bark of a side branch. The gallery commenced in this. 
The young larva on hatching out had bored straight 
to the heart of the branch and then bored down its 
centre till it reached the main stem, down the heart- 
wood of which it carried its tunnel. Length of gallery 
in main stem 7 inches. The larva had pupated at the 
end of the gallery, the extreme end of it being packed 
with wood chips. The rest of the gallery, with the 
exception of the pupal chamber, was blocked with 
a dark red hard mass (the heart-wood is reddish) 
consisting of chewed wood. A large hole starting at 
one side near the upper end of the pupal chamber was_ 
Sored horizontally through the wood to the outside, 
This exit-hole was very visible on the outside of the 
stem. 
grd—Old Gallery.—This one also commenced in a side 
branch, the larva working down the branch into the 
main stem and then down the centre of this latter, 
finishing up close to where No. 2 joined the main 
stem. It did not join this latter, Length about 1 foot. 
An air-hole had been bored to outside. Exit-hole 
of beetle bored in the same way as in No, 2. 
4th— A New Gallery.—Contained a living larva which was 
about to pupate. It had enlarged the end of its 
gallery for this purpose. About 3 inches of the gallery 
was free of the compressed wood excreta. Length of 
gallery 114 inches. Was confined tocentre of the stem 
and contained one air-hole bored to outside about 
half-way down, In this case the egg must have been 
laid by the mother beetle either on the outside of 
the bark ina crevice or in the softer layer of tissue 
below. 
5th—Old Gallery.—This gallery started at the point where 
tbe main stem branched into two or three forks, z.e., 
where the crown commenced. It began about 14 inch
