46 SCOLYLUS SP. 
The over-wintering larva were discovered by Mr. Ribbentrop: 
curled up in the end of their galleries in the pupa-cradle. In 
other cases he found a hole at the end of the larval gallery 
- through which the perfect beetle had made its exit from the tree. 
It will not unlikely be found that the October beetles bore a 
little way into the bark of fresh trees and hibernate in it through 
the winter, coming out ta May of the following year and boring. 
into fresh trees to lay the eggs of the first generation of the year. 
Localities from which reported. 
The insect was first discovered by Mr. Minniken in the 
deodar forests of the Bashahr State in August 1900. The fol- 
jowing year the writer found it in ceodar trees in the Jaunsar 
division of the North-West Provinces some 100 ‘miles or so to 
the south-west of the area in which it was originally discovered. 
Relations to the Forest. 
The discovery of this Sco/ytus is of some scientific interest, 
since | am not aware that the genus Sco/ytws has previously 
been reported as attacking conifers in India. It does not do 
so in Europe, where it confines its attacks to broad-leaved trees, 
although it has been reported from America in this connection. 
The beetle up to date has only been found attacking pole 
forest, boring galleries which are partly in the bark and partly 
in the outermost layers of the wood of the trees. 
The mother gallery is from 24 to 34 inches in length, ascend- 
ing and vertical, consisting of a series of short zig-zag curves 
along both sides of which small notches. are gnawed out and an 
egg deposited in each. The secondary galleries ramify from it 
in a most graceful manner, the ones taking off from the centre 
portion of the main gallery being at right angles, whilst those 
more; remote trend away from these at ever-widening angles, 
the upper ones in an upward direction, the lower ones ina 
downward one. These galleries are “not broader at their 
ends than the mother gallery; they lie close together and are 
long, sometimes as much as 3} to-4 inches though generally 
about 3 inches inlength. See PI. IV, fig. 4, c. Pupal. chambers 
are excavated in the bark or sap wood.
