It is probable that the beetle will be found on the \ving some time during the summer months, and it may be that the larvae pupate at irregular intervals through-out the summer, so that some beetles will always be found between June orJuly and October. This point has to be definitely ascertained.

The following description of a patch of deodar sowingexamined by myself is typical of what occurs and of what took place inMr. Billsons infested sowings :— There were probably twenty-five seedlings originally in the patch. Atthe time of inspection five green unattacked ones were all that remainedstanding in the soil. Of the rest a few dead ones remained standing, andthese came away in the hand, being cut through below the surface, or theroots came away with the dead upper part and were seen to be girdled.
