obtained, which, as the borings both of beetle and larve go down 
into the sapwood as well as up into the bark, remains indelibly 
impressed on them (see PI, X, fig. 3, d, and Pl. XI, d). 
When full fed, the larva bores a small pupating chamber half 
in the sapwood and half in the bark, and pupates within it, In 
saplings the pupating chamber is bored at times entirely in the 
wood at a little distance from the end or at the end itself of the 
larval gallery (see Pl. X, fig. 3,d(3)). The beetle on maturing 
bores its way out of the tree by a horizontal tunnel to the 
outside. i 
The mother gallery of this small Sco/ytus is from ths to 24 
inches in length (Pl. X, fig. 3, d, and Pl. XI, d), though it may 
be even shorter, and, as! have said, is composed of a series of 
continuous short zig-zag curves. The larval galleries branching 
off from this are about 1 to 2} inches in length and increase in 
breadth as they get further and further away from the main 
gallery. The egg galleries made in the bole of large trees are 
usually shorter than those made in their branches or in saplings 
and small poles. 
The beetles which appear in May are those of the overwin- 
tering stage, having hibernated through the winter either as larva 
or beetles, and they lay the eggs of the first generation of the 
year. About a month is spent in the larval state at the higher 
elevations, the grubs which hatch out during the last week in 
May becoming full grown in the last week in June. The beetles 
from these issue in July. 
| have not at present any notes on the further life history of 
the pest, but as the latter is up to this period identical with 
that of its companion, Scolytus major, it will probably be 
found to run through a second generation before the close of 
the year (see No. 1, p. 45). 
Locality from where reported. 
This beetle was discovered by the writer in 1go1 in the Jaun- 
sar Bawar and Tehri Garhwal deodar forests of the Jaunsar 
Division in the United Provinces.

From the descriptions giver of its habits it is evident that 
this insect is capable of proving a serious pest to the deodar
