1096 CYRTOTRACHELUS LONGIPES. 
as a decaying lump of vegetation mixed with earth mould, 
From the above account it becomes apparent that some ten 
months of the insect’s life history are passed in the pupal stage, 
about 5 weeks in the imago and egg-laying stage (excluding the 
period the insects remain alive after egg-laying, which period 
requires further observation to ascertain definitely the number 
of eggs laid by the beetle) and three to four weeks in the larval 
or destructive stage. 
Locality from where reported. 
This weevil is plentiful in the Chittagong Hill Tracts in the 
bamboo jungles adjacent to the Karnafuli river. 
It has also been reported from the Cape of Good Hope. 
Relations to the Forest. 
C. longtpes has proved a most serious pest to the Melocanna 
bambusotdes bamboo killing off young shoots over a fairly wide 
area both in r899 and 1goo. In these years large numbers of 
young bamboo shoots were observed springing up in the forests 
at the commencement of the rains. By August some 30 to 4o 
per cent. on areas inspected round Kaptai and elsewhere had 
been killed off, in the damper localities the attack being even 
more severe, The infestation appeared to diminish as the 
moister localities near the river were left behind, and almost 
disappeared as one went up the slopes of the hills. I am of 
Opinion that the severity of the attack was probably due to 
the great clearance made in the portions of the forest which 
lay in the path of the great cyclone of October 1897 which 
swept up into the Hill Tracts from the Bay of Bengal, destroying 
some valuable teak plantations near Kaptai and laying low most 
of the trees it met with far up into the hills. As a result 
of this clearance of large tree growth in the forest, the muli 
bamboo commenced to shoot up in dense masses during the 
rains of 1898, and this was followed by the heavy and localized 
attacks of the beetles in 1899 and1goo. I have-no information 
as to whether they were continued the following year, as I 
was unable to visit the area in question,
