Soon the damaged shoot flags and later falls with the contained maggot or egg to the ground. The curious cut off and blunt shoots are very charac- teristic on attacked trees. The yellow ovum liatches in a few days, and the wdiite footless maggot feeds upon the pith and in a month it reaches maturity. It then leaves its shelter and pupates in the soil, in a small earthen cell. In dry weather large numbers of them doubtless die, owing to the shoot and pith rapidly shrivelling up. As far as 1 could obsei'\-e the pupa remains in the snil until the following spring. The only treatment consists of jarring oft' the Vieetles and raking together the fallen shoots and burning them.

It is steel blue in colour, the thorax finely punctui'ed and slightly pubescent; elytra with punctate stria', the interstices also furnished with a single row of punctures ; antenna-, I'ostrum and legs deep steel blue; length ji,, inch. <Jn the Continent it seems to do serious damage at times.
